▼ Fossil fuel burning within residential, industrial and power generation sectors represents a persistent source of air pollution within many parts of South Africa, with the contribution of road transport emissions becoming increasingly important. Additionally, biomass burning, including agricultural burning and wild fires, represents an intermittent but seasonally significant source of atmospheric emissions. Effective air pollution control was historically hindered by the absence of enabling legislation and cooperative governance. The promulgation of the National Environmental Management: Air Quality Act, Act 39 of 2004 represented a major step forward in the evolution of air quality management within South Africa. The historical debate regarding the practicability of effective air quality management is however ongoing. South Africa‟s continued dependence on coal to support its energy-intensive industrial and mining sectors, continued household fuel burning for space heating and cooking purposes within a number of areas, and the dire need for employment creation and focus on rapid development continue to challenge the realisation of air quality improvements. This study investigates the multiple factors contributing to the degradation of air quality in South Africa, and the consequent human health, environmental and economic effects of this pollution. The study critically examines legal, technical and social measures implementable within a tailored system of air quality management which is compatible with socio-economic growth. This thesis integrates and expands on pertinent components of several individual research projects completed by the author during her tenure as a doctoral candidate. The research projects were completed during the period (2002 – 2009) on behalf of various parties including national and local government, standards setting bodies and private organisations. Quantification of health risks associated with significant anthropogenic sources within several South African conurbations, covering 40% of the national population, and the establishment of cost-optimised air pollution interventions, forms a key component of the thesis. In this externalities study, emissions were estimated and effects and associated costs quantified for household fuel burning, power generation, industrial and commercial fuel burning and road transport. Total direct health costs related to inhalation exposures to fuel burning emissions were estimated to be of the order of 3.5 billion 2002 Rands per annum across health effects, conurbations and source groupings assessed. Household fuel burning was estimated to be responsible for about 68% of the total health costs estimated across all conurbations, vehicle emissions for 13%, industrial and commercial fuel burning for 13%, and power generation for about 6%. Emission reduction opportunities were identified and assessed for residential fuel burning, coalfired power generation, road transport, coal-fired industrial boilers and specific individual industries. It was concluded that…

The production of energy and chemicals from renewable resources has gained
significant attention as the global effort and legislated requirements to transition
from fossil fuels to biofuels intensifies. The synthesis of furfural from biomass has
resulted in extensive fine chemical production. The main hydrogenation product of
furfural is furfuryl alcohol which has been produced industrially with the use of a
copper chromite catalyst. Elimination of the environmentally toxic Cu-Cr catalyst
was the focus of this research culminating in the synthesis of a reusable bimetallic
catalyst with high selectivity to furfuryl alcohol.
This work initially focused on the synthesis of monometallic catalysts by wet
impregnation and concentrated on metals such as platinum, palladium, copper and
nickel. Platinum displayed higher selectivity to furfuryl alcohol while palladium
showed higher furfural conversion under the conditions studied. Experiments
conducted using ethanol as the solvent had a negative effect on the selectivity to the
desired product, furfuryl alcohol, with high quantities of 2-furaldehyde diethyl acetal
and difurfuryl ether also formed. Commercial catalysts were employed which
confirmed the involvement of ethanol in the formation of additional products.
Consequently, toluene was selected as an alternative solvent facilitating selectivity to
furfuryl alcohol only under all conditions studied. A 0.9%Pt/SiO2 catalyst was
selected as the most suitable catalyst for furfural hydrogenation to furfuryl alcohol
following characterisation which highlighted that increased metal loading resulted in
a larger particle size and lower metal dispersion. This catalyst became the focus of
subsequent research.
Subsequently, the focus of the research was the production of bimetallic catalysts
using the 0.9%Pt/SiO2 catalyst as a base for the selection of promoter metals. The
bimetallic catalysts were synthesised using the controlled surface reactions
technique. It was found that, while the selectivity of all catalysts to furfuryl alcohol
was close to 100%, the conversion was influenced significantly by the promoter
metal and followed the order tin>molybdenum>manganese>barium>iron>nickel.
Furfural conversion of 47% and close to 100% selectivity to furfuryl alcohol was
achieved using a 0.6%Pt0.4%Sn/SiO2 catalyst at 100°C and 20 bar hydrogen
pressure.
Synthesis techniques including sequential impregnation and co-impregnation were
investigated and compared to the controlled surface reactions technique. Coimpregnation
was the best technique giving a furfural conversion of 62 % compared
to the controlled surface reactions catalyst with 47% conversion. Detailed
characterisation of the controlled surface reactions catalyst
0.6%Pt0.3%Sn/SiO2(CSR) and the co-impregnation catalyst 0.7%Pt-
0.3%Sn/SiO2(Co-I) demonstrated electronic modifications of the bimetallic catalysts
caused by charge transfer from platinum to tin. TEM analysis showed that the
particle size ranged from 1.5–3 nm for the…

A major challenge facing the world is the need to enhance sustainability urgently as
we face the inter-related challenges of climate change, dependence on fossil fuels,
food shortages and growing population. The International Panel on Climate Change
indicates very high confidence that the effect of human activities has been one of
warming. If nations are to stabilise carbon dioxide (CO2) concentrations at 550-
590ppm, then global emissions need to peak between 2010 and 2030. Given the
slow movement towards a more sustainable system, more radical and systematic
policies are needed. While technological development is crucial, significant gains
may be made through the wider adoption of existing proven technologies through
improved planning and behaviour change, on the basis that if such technologies be
used to their full effect there would be a large reduction in human impact on the
environment and dependency on fossil fuels. It is however unclear to policy makers
which technologies should be prioritised and there is need for quantitative evidence
to guide policy prioritisation and implementation. Work described here aims to
identify and evaluate feasible policy interventions aimed at Irish citizens which
would be expected to increase sustainability. Quantitative data on more than 300
economic, social and environmental attributes of 79 small to medium sized
urban Irish settlements were assembled into a database. This provided a baseline
against which projected impacts of fresh policy implementation may be
evaluated. The method has been named Sustainability Evaluation Metric for Policy
Recommendation (SEMPRe), and is designed to be user-friendly for decision
makers. SEMPRe assigns each candidate policy a numeric value indicating its
projected effectiveness in enhancing settlement sustainability as an aid to evidence
based decision making. SEMPRe estimates the impact of proposed policies, using
peer-reviewed published analyses and direct Irish experience. The most cited and
appropriate policies were chosen in the policy arenas of transport, food, housing and
urban form, energy, waste and water. As a further step in facilitating selection of
most appropriate policies, a novel method using multi-criteria decision analysis was
developed for feasibility testing of policy initiatives. As further quantitative
assessment of impacts of additional policies are published in future, the range
of policies testable will increase. The method has been developed for Irish urban
areas but may have relevance for policy prioritisation in other comparable states.

▼ In a relatively short time, the fossil-fuel divestment movement has emerged with global momentum, in light of the industry’s influence on carbon induced anthropogenic climate change. Divestment is pursued by investors as a means to either mitigate against the risks of a tightening carbon budget and of stranding assets or as a means of activism to force change on the fossil fuel industry. Literature on the topic to date suggests that divestment may have a direct impact on share prices or indirect impact stigmatizing the fossil fuel industry. Conversely, skeptics argue that divestment may be too small to have a measurable impact. However, there is no empirical study that distinctly measures the impact of divestment and related events on the fossil fuel industry.
The objective of this thesis is to objectively measure the impact of divestment events and compare its efficacy relative to similar events. Thus, the purpose of this thesis is two-fold, asking whether divestment events impact the fossil fuel industry and whether divestment events are more impactful than events on the carbon budget and stranded assets. In line with existing literature from the anti-Apartheid divestment movement, this study adopts the event study methodology to measure the impact.
The findings indicate that announcements of fossil-fuel divestment, stranded assets, and the carbon budget do negatively impact the share price of fossil fuel firms equally, on and around the event date. These results infer that the financial market perceives divestment and related events to be a material threat to the performance of fossil fuel firms. This thesis contributes to existing literature on fossil-fuel divestment by strengthening the ethical case that divestment can not only ‘do well’ as a financial tool but ‘do good’ as an activism tool as well.

▼ Research Doctorate - Doctor of Philosophy (PhD)
Historically, fossil fuels have been vital for our global energy needs. However climate change is prompting renewed interest in the role of fossil fuel production for our energy needs. In order to appropriately plan for our future energy needs, a new detailed model of fossil fuel supply is required. It is critical to know if fossil fuels will still be able to supply most of our energy requirements and meet the ever increasing energy demand in the future. Answering these questions is critical in order to identify potential periods of energy shortages; so that alternative energy resources can be utilised in a timely way. The aim of this study was to develop a model to predict fossil fuel production for the long term based on historical production data, projected demand, and assumed ultimately recoverable reserves for coal, gas and oil. Climate change is an important issue confronting society, and it is hoped that the work contained in this thesis will aid climate change modeling by focusing attention to realistic fossil fuel production projections.Fossil fuels are currently an essential component in the global economy and the growth of the human population. The fossil fuel production projections from this study suggest that many of the IPCC fossil fuel projections appear overly optimistic. Based on the assumed URR values, it is predicted that global fossil fuel production will peak before 2030. For this reason, it is imperative that appropriate action be taken as early as possible to mitigate the effects of fossil fuel decline, to avoid energy shortages in the near future.

▼ M.Ing. (Mechanical Engineering)
Fossil fuels have been the backbone for the world in terms of fulfilling energy requirements. One of the best used types of fuel is the coal due to its availability throughout the globe. However, the coal resources cannot be reproduced hence the future generation may be negatively affected by the present method of generating energy. Unfortunately, these resources have undesirable effects to the environment which may lead to global warming. Other various sources may include oil and gas, nuclear, and the renewables. Oil and gas have diverse use currently especially in the transportation of goods and people across the continents. Nuclear energy is a mature technology but recent disasters have led to the public to be anti-nuclear. This perception is also fuelled by the in NGOs who are staunch supporters of renewable power. In addition, the issue about nuclear energy revolves around the undesirable side effect like the production of atomic bombs which are dangerous weapons ever. To produce nuclear energy, usually uranium is used which is also not available in abundance. Therefore, limiting their use will ensure that our future generations enjoy these benefits. Renewable sources like wind, wave, and solar, hydro, geothermal and tidal energies needs to be explored further for the sake of our future generations. The challenges which are faced by policy makers regarding the fossil fuels include catastrophic disasters which require billions of dollars in the form reconstruction after heavy drought and floods which damage the infrastructure and the economy at large. These disasters can be prevented if all governments are working together to eliminate or reduce the causes of climate change due to global warming. Unfortunately climate change must be addressed by all nations as it is no use for say one country to reduce emissions while others are not doing enough as we share the same atmosphere. The cost of renewable energy has been on the decline as the technology becomes more mature and the installed capacity across the globe increases. Thus more data is available to obtain understanding about the operations and maintenance of these systems. The other advantages of renewable sources are input costs are minimal for example wind energy comes from wind which is free. Same applies to solar energy which uses radiant energy from the sun which is also freely available. The coal and nuclear fuel power stations are currently in the forefront due to the fact that both stations may be used as based load to maintain grid stability in terms of power frequency. The renewable energy sources are very unreliable as they heavily dependent on weather. Unfortunately weather cannot be controlled.The renewable power is derived from biomass, geothermal, hydroelectric, solar, wave and wind. The renewable power tends to be the most expensive option in comparison to the traditional sources (coal, oil and gas, and nuclear). Technology for electricity generation from these renewable sources is now becoming mature and both…

▼ Against the backdrop of rising fuel prices and increasing transport fuel demand, biofuel production, driven by the potential to contribute to energy security, climate change mitigation and rural development has experience rapid growth in recent years. Apart from a few private initiatives, South Africa has no commercialized biofuel industry to date. The concerns are that economic, environmental and socio economic issues can be a hindrance to the success of the industry. In response to these concerns this research intends to ascertain whether biofuel production could offer a viable economic alternative to
fossil fuels in South Africa. For decision makers it is hard to find reliable reference material and solid guidance. Uncertainty over the potential risks and benefits has left potential investors unsure whether biofuel production could be a viable investment opportunity. The aim of this study was to determine if the benefits derived from biofuel production are significant enough to justify the substantial investment required. The findings reveal that in the absence of clear government strategies and the availability of low cost feedstocks the production of biofuel cannot be viewed as viable. The results show that bioethanol from grain sorghum and sugarcane are not economically viable since the results turn out to be negative in terms of both net present values (NPV) and internal rate of return (IRR) calculations, thus rendering a viable payback (PBP) period as unattainable. Similarly, the NPV and IRR for biodiesel from soya beans and sunflower is negative and the PBP also unattainable. Sensitivity analyses indicate that these crops (except for sunflowers) could only become viable if there were to be a substantial reduction in feedstock prices. All other changes in parameters would not render any of the production plant viable.

Carbon dioxide (CO2) is one of a number of gases known as green-house gases which are believed to contribute to global climate change. Anthropogenic sources of CO2 emissions have increased significantly in the atmosphere. It is believed that the burning of fossil fuels in electric power generation plants is one of the main contributors as in these plants CO2 is released in the flue gas. This is one of the most serious challenges facing our world.
The current liquid amine scrubber used for CO2 capture from flue gas stream is inefficient. This work focused on the synthesis of a more efficient solid amine sorbent to remove CO2 from flue gas streams and also ambient air. Two amines; APTES and TEPA were successfully fixed onto SBA-15, Al-SBA-15 and PE-SBA-15. These solids successfully removed CO2 from a gas stream from the laboratory test rig. 70%TEPA/SBA-15(I) showed a particularly high capacity and proved stable over 5 CO2 adsorption/desorption cycles. This solid also successfully captured CO2 from ambient air with a relative humidity of 89 % and 100 %. This solid is one of the highest capacity solids for CO2 capture from ambient air.
Two methods of pelletising were investigated. The first method utilised the use of a binder and plasticiser (kaolin and methylcellulose). This method was used to pelletise SBA-15, resulting in cylindrical pellets 1 mm in diameter and 2 mm in length. 70%TEPA/SBA-15(I) was not successfully pelletised using this method, as TEPA was lost during the calcination stage. Therefore the SBA-15 pellets were modified after pellet formation. The second method involved simply pressing 70%TEPA/SBA-15(I) into a circular pellet. The binder based method produced strong, durable pellets, while the self-supported method produced less durable pellets. It is likely that the binder adds strength to the SBA-15 pellets as it bind the SBA-15 particles together into a cohesive unit.
The effect of pressure and temperature were also investigated on 70%APTES/SBA-15(CI) and 70%TEPA/SBA-15(I). Temperature, in particular was found to impact adsorption capacity, while both solids showed high CO2 uptake at low partial pressures. Overall, the solids showed adsorption characteristics similar to the Dual-

▼ peer-reviewed
Hydrogen is increasingly used in a variety of applications and holds promise as a replacement for fossil fuels. Biomass derived formic acid represents an excellent renewable material for hydrogen storage. This thesis is devoted to an investigation of different catalysts aiming ultrapure hydrogen production from formic acid decomposition.
Two research directions were considered: (I) decomposition of formic acid over Au catalysts supported on a selection of metal oxides, and (II) decomposition of formic acid over Ru, Pd and Pt catalysts supported on a variety of N-free and N-doped carbon materials. A series of characterization methods were applied to understand the promotion of the catalysts with the nitrogen incorporated into the carbon structure, which should be taken into the account when designing a catalyst for particular use.
A study of ~2.5 wt.% Au catalysts supported on different metal oxides (Al2O3, ZrO2, CeO2, La2O3 and MgO) with the same mean Au particle sizes showed that alumina is the most efficient support for stabilization of Au species providing almost CO free hydrogen production for at least 16 h. High activity of Au catalysts was associated with acid–base properties of the support.
N-doping of Ru catalysts supported carbon nanofibers (CNFs) demonstrated an increase of the rate of the formic acid dehydrogenation reaction and lead to an increase of the selectivity to hydrogen from 83 to 92%. The increase in activity was explained by coordination of the Ru species by pyridinic nitrogen located on the open edge of graphene layers of the herringbone type CNFs used.
The effects of preparation variables, structure of the carbon supports (carbon nanofibers and porous carbon network), and surface functional composition on catalytic properties of the Pd and Pt catalysts were studied. Single Pd atoms and single Pt atoms on nitrogen-functionalized carbon materials, observed by aberration-corrected scanning transmission electron microscopy were found to contribute considerably to the catalytic activity, selectivity and did not affect the stability of the catalysts at least for 30 h in hydrogen production. XPS analysis proved the presence of Pd2+ ions in significant concentration even after treatment of the catalyst with H2 and interaction of Pd atoms with pyridinic nitrogen of the support was recognized.

▼ ENGLISH ABSTRACT: The development and application of biorefineries is the promising effective use of lignocellulose in the substitution of
fossil fuel-based chemicals, materials and
fuels. The biorefineries are attractive as they will utilise all lignocellulose components (cellulose, hemicellulose and lignin) for production of various products. The biorefineries require efficient lignocellulose fractionation methods, which are able to overcome the recalcitrance of lignocellulose to dissolution and chemical conversion, giving high yield, purity and preferably polymeric forms of all three major fractions.
The aim of the study was to compare organosolv and ionic liquid fractionation methods on sugarcane bagasse (SCB) and Eucalyptus grandis (E. grandis), in terms of extraction and separation efficiencies, as well as operational challenges. Effects of alkaline extraction of hemicellulose on efficiencies of organosolv and ionic liquid fractionation methods were also studied.
The choice of feedstocks was based on the availability and industrial processing in the Southern Hemisphere. Alkaline pre- and extractions of hemicelluloses were carried out using sodium hydroxide solutions. Organosolv fractionation of both SCB and E. grandis was carried out using aqueous ethanol and conditions adapted from Huijgen et al. (2012). The ionic liquid used was 1-ethyl-3-methylimidazolium acetate, [EMIM]OAc. Central composite design of experiments was used to optimise aqueous ionic liquid fractionation, and obtained desirable conditions were used for comparison study. The mass balances and quality of fractions were used to compare organosolv and ionic liquid fractionations in terms of extraction and separation efficiencies.
The results obtained showed that alkaline pre-extraction method extracted and preserved hemicellulose (xylan) in polymeric form. Alkaline pre-extraction solubilised significant amount of hemicelluloses, and that preserved reasonable amount of hemicellulose from degradation by either organosolv or ionic liquid process. When alkaline post-extraction was coupled with organosolv and ionic liquid fractionation methods, the recovered hemicelluloses had lower molecular weight, and were accompanied by very low xylan balances. The alkaline pre-extraction combinations with organosolv and ionic liquid fractionation methods outweighed alkaline post-extraction combinations.
Ionic liquid fractionation yielded highly digestible solid residues (≥98 %), while organosolv yielded less digestible solid residues (≤63 %). Both organosolv and ionic liquid fractionation methods resulted in high quality lignin. Ionic liquid fractionation outweighed organosolv process in terms of hemicellulose preservation. In terms of robustness to different feedstocks, ionic liquid fractionation was more robust than organosolv process. In terms of separation efficiencies, ionic liquid fractionation produced fractions which were easily separated than organosolv process (particularly hemicellulose-lignin mixture). Although ionic liquid fractionation outweighed…

▼ While many are aware of the inputs required to maintain food production at an
industrial level in the United States, we seldom reflect on the profound significance of a
food system that is so deeply rooted in what Matthew Huber calls the “dead ecologies
of fossilized energy.” In order to more fully understand and critique the linkages
between fossil fuels and agriculture, as well as their ecological and social implications, I
examine the use of fossil fuels in agriculture through an eco-socialist framework. I
employ Wim Carton’s fossil fuel landscape and Marx as developed by John Bellamy
Foster’s concept of metabolic rift to illuminate the linkages between combustible
carbons and the food we eat. Ultimately, these two concepts lead to a place of critical
understanding in attempts to envision a more sustainable and resilient future. Such an
inquiry is of the upmost urgency considering the dual threats of climate change and soil
erosion. Both threats are exacerbated by our continued use of fossil fuels and the
machines they power.

▼ Energy production from coal comes with an environmental cost because of the toxic waste produced during coal combustion such as coal ash and brine which are potential water and soil pollutants. Coal ash and brine contain toxic elements which can leach and contaminate soils and ground water if not properly disposed. This study investigated the mobility of species in coal fly ash co-disposed with brine at Sasol Secunda power station in order to establish if the ash dam could act as a salt sink. The ash was dumped as a slurry with 5:1 brine/ash ratio and the dam was in operation for 20 years. It was hypothesized that the disposed Secunda fly ash was capable of leaching toxic metal elements into the surrounding soils and ground water and therefore could not be used as a long term sustainable salt sink. Weathered fly ash samples were collected along a 51 m depth core at the Secunda ash dam by drilling and sampling the ash at 1.5 m depth intervals. A fresh fly ash sample was collected from the hoppers in the ash collection system at the power station. Characterization of both Secunda fresh ash and Secunda weathered ash core samples was done using X-ray diffraction (XRD) for mineralogy, X-ray fluorescence (XRF) for chemical composition and scanning electron microscopy (SEM) for morphology. Analysis of extracted pore water and moisture content determination of Secunda fresh ash and Secunda weathered ash core samples was done in order to evaluate the physico-chemical properties of the fly ash. The chemical partitioning and mobility of metal species in the ash dam was evaluated using the sequential extraction procedure. The XRD spectra revealed quartz, mullite and calcite as the dominant mineral phases in the weathered Secunda ash core samples while Secunda fresh ash contained quartz, mullite and lime. The major oxides identified by XRF analysis for both Secunda fresh ash and Secunda weathered ash include: SiO₂, Al₂O₃, CaO, Fe₂O₃, MgO, Na₂O, TiO₂ and K₂O. The minor oxides identified for both Secunda fresh ash and Secunda weathered ash were P₂O₅, SO₃ and MnO. The trace elements identified for both Secunda fresh ash and Secunda weathered ash were As, Ba, Ce, Co, Nb, Ni, Pb, Rb, Sr, V, Y, Zr and Th. However, U was detected in some of the Secunda weathered ash samples but not in Secunda fresh ash. Both Secunda fresh ash and Secunda weathered ash was classified as class F based on the sum of the oxides of silicon, aluminium and iron by mass and the CaO content as reported by XRF analysis, and further classified as sialic and ferrocalsialic type highlighting the significant levels of Si, Al, Ca and Fe in the fly ash based on XRF analysis. The XRF analysis further showed that brine codisposal on the ash may have been responsible for the slight enrichment of some species such as Na, SO₄²⁻, Mg, K and V in the disposed Secunda weathered fly ash. However, there was no significant accumulation of these species in the disposed fly ash despite continuous addition of an estimated 117.65 billion litres of brine over the 20 year period that…

▼ Colorado's forests are facing threats from wildfires, insect and disease epidemics and human encroachment. At the same time, Coloradans are facing energy security problems from
fossil fuel price volatility, unintended consequences from continued
fossil fuel dependence, problematic alternative, non-renewable fuel promotions and a struggling renewable energy industry. Subsequently, natural resources managers in Colorado are facing two imposing challenges simultaneously: 1) the need to restore forest health and 2) to manage energy resources sustainably, equitably and with public safety in mind. Policy entrepreneurs invested in forest energy found ways to link forest health emergencies to energy security crises. This dissertation is a study that explores how that link was forged and what happened in Colorado as result, looking at the actions taken by the four major federal land management agencies (U.S. Forest Service, Bureau of Land Management, National Park Service and the U.S Fish and Wildlife Service). This study also traced briefly how the State of Colorado responded to these crises, too. First, this study qualitatively surveyed literature in the forest history and policy arenas and energy history and policy arenas to chart how prior events led to current conditions. Media articles were tabulated and coded to quantitatively gauge how salient their respective issues were over time. Using Multiple Streams Theory, policy windows were identified. Second, the Punctuated Equilibrium Theory was applied to the emerging forest energy policy arena during the time frame identified by the policy windows. Finally, interviews and meetings were held with employees at the federal, regional/state and local levels and with members of state government to determine how the increased saliency of forest and energy issues translated to forest energy policy actions on the ground in Colorado. This dissertation concludes that federal land management agencies took greater interest and made significant efforts to promote forest energy in Colorado between the years 2000 and 2013. This increased interest resulted in increased funding, regulation and project development and implementation in the state. However, while activity increased, opportunity for additional actions remains. Coloradans would be wise to foster additional public-private initiatives and work to promote forest energy among large groups of proximal forest communities. Inevitably, as
fossil fuel supplies decrease and prices increase, Colorado, along with the rest of the country, will in part be forced to return back to its "roots" and Dukert's notion of "the future behind us."

▼ Biomass gasification is considered a key technology in reaching targets for renewable energy and CO2 emissions reduction. This thesis studies the feasibility of a new technology of biomass gasification called WoodRoll for the production of Syngas with the aim to replace fossil fuels in the furnaces of the steel company OVAKO in Hofors. This research attempts to study the techno-economic viability of WoodRoll technology integration with the district heating company HEAB, creating a synergy between the companies and WoodRoll technology. Moreover, a theoretically study of the environmental impact, concerning greenhouse effect and pollutants it is also carried out. In the future scenario HEAB, as an energy supplier will be the gasification plant owner supplying with Syngas 5% cheaper than the fuels that they use today to Ovako. Three different scenarios have been studied varying the capacity of the gasification plant. The scenarios are 5MW, 10MW and 15MW capacity. The study show that the system is technically viable being possible to create a synergy between the three process improving efficiency and decreasing cost and CO2 emissions. The results from the economic study show that biomass gasification using WoodRoll technology is a highly interesting investment option for HEAB. From Ovako side, the project is very interesting too since the company can have a combustible 5% cheaper than the fuels used today without doing any investment. In 5MW scenario, 40GWh per year are converted in Ovako from oil to Syngas. With an investment for HEAB of 9.8 mSEK, profits were a Net Present Value of 6.3mSEK with 7.8 years of payback period. In 10MW scenario 80GWh were replaced. In this scenario, required investment was 146 mSEK with a NPV of 32.5 mSEK . Payback in this case was 6.3 years. The most profitable scenario was the case of 15M. With an investment of 188 mSEK the profits of the project were 60mSEK with a payback period of 5.8 years. In the three cases, especially in 15MW case, sensitivity study of the system show that it is very robust to changes in biomass cost and Syngas price. This parameters have a big impact on the profits but a big margin until becomes unfeasible. From Ovako side, savings for the fuel conversion were 1.2; 2.4 and 3.6mSEK for the 5, 10 and 15MW respectively. Reduction of CO2 emissions was 11, 20 and 30 thousands of CO2 tons for the three scenarios allowing the company to sell CO2 allowances and having an extra profit of 3, 6 and 8mSEK per year in the 5, 10 and 15MW scenario respectively.

▼ With limited indigenous conventional energy resources, Mauritius imports over 80% of its energy supply from foreign countries, mostly from the Middle East. Developing independent renewable energy resources is thus of priority concern for the Mauritian government. A tropical island surrounded by the Indian Ocean, Mauritius has enormous potential to develop various renewable energies, such as solar energy, biomass energy, wind power, geothermal energy, hydropower, etc. However, owing to the importance of conventional fossil energy in generating remarkably cheap electricity, renewable energy has not yet fully developed in Mauritius, resulting from a lack of market competition. So, in order to reduce the external dependency of fuel, and also to cut down the expenses involved in the imported fuels, the Mauritius Government introduced attractive policies and invited investors of the homeland and abroad to invest in renewable energy technologies. Consequently, numerous promotional and subsidy programs have recently been proclaimed by the Mauritian government, focused on the development of various renewable energies. Thus, the Government of Mauritius has a long-term vision of transforming Mauritius into a sustainable Island. One important element towards the achievement of this vision is to increase the country’s renewable energy usage and thereby reducing dependence on fossil fuels. Democratisation of energy production is determined to be the way forward. A step in this direction is to transfer citizens the ability and motivation to produce electricity via small-scale distributed generation (SSDG), i.e. wind, photovoltaic, Hydropower. As a stepping stone the Government and the Central Electricity Board, with the help of the UNDP, established a grid code in May 2009 which encompasses tariffs and incentive schemes that have in many countries proved essential in order to achieve any substantial development in renewable electricity production based on SSDG.
In line with the government’s vision on renewable energy, the University of Mauritius is working as a partner with DIREKT team to promote renewable energy infrastructure locally. The DIREKT (Small Developing Island Renewable Energy Knowledge and Technology Transfer Network) is a teamwork scheme that involves the participation and collaboration of various universities from Germany, Fiji, Mauritius, Barbados and Trinidad & Tobago. The aim of the DIREKT project is to reinforce the science and technology competency in the domain of renewable energy through technology transfer, information exchange and networking, targeting ACP (Africa, Caribbean, Pacific) Small Island developing states.
This study was therefore initiated to investigate the main renewable energy technologies that stakeholders, institutions as well as businesses and organizations would like to invest in Mauritius based in the attracting incentive schemes provided by the Government.
From the study it was found that the majority of the Organizations, Institutions,…

Tax Policy Analysis in a Flexible Computable General Equilibrium Model: Applications to Energy and Gross Receipts Taxation.

▼ In this paper, I construct a new general equilibrium model of the United States economy that is better able to analyze energy and gross receipts taxes than previous models. Existing models in the energy literature fall into two groups: general equilibrium models of the entire economy with exogenous energy resource supply and partial equilibrium models of the energy sector with endogenous resource supply. I combine the main advantages of these two strains of the literature by incorporating endogenous resource supply in a computable general equilibrium model with highly disaggregated and flexible industry cost and consumer expenditure functions. My new model is able to analyze all the major inefficiencies caused by energy taxation, i.e. those related to production, consumption, resource rents, and externalities.
In addition to its application in energy, my model is also ideal for looking at gross receipts and retails sales taxes. Gross receipts and retail sales taxes are important revenues sources for most US states and share many of the same issues as energy taxes. Retail sales taxes are commonly viewed as more efficient than gross receipts taxes because the latter apply to intermediate goods and thus result in production and consumption inefficiencies. However, in reality the retail sales taxes used by the US states are not pure consumption taxes, but tax many intermediate inputs while exempting many consumption goods. My model determines whether retail sales taxes are still more efficient than gross receipts taxes when these realistic factors are included.
As an application, I use the model to analyze two tax reforms for energy or gross receipts taxes. First, President Obama's 2014 budget proposes to reform energy taxation by eliminating
fossil fuel tax preferences. I find that the budget's tax increases for
fossil fuels increase household welfare if the social cost of carbon emissions is over $15 per ton but otherwise reduce welfare. Second, I also use the model to examine a tax reform that replaces a typical retail sales tax with a generic gross receipts tax. Contrary to the conventional wisdom, I find that the gross receipts tax is more efficient than the retail sales tax, with an efficiency cost that is 6.8 percent of revenues less than that of the retail sales tax. These results demonstrate that the predicted impacts of the tax reforms are significantly altered by the features included in my model: general equilibrium effects, flexible substitution, resource rents, and externalities.

▼ Since the Industrial Revolution,
fossil fuels have provided a cheap and efficient source of energy. Reliance on
fossil fuels, especially oil, supported economic growth under capitalism but also has led to climate change. As peak oil approaches, a transition towards renewable sources of energy is mandatory for ensuring future prospects of development and for reducing the effects of climate change. The transition to renewable energy sources could be made smoother if the subsidies provided to the
fossil fuel industry were phased out and governments provided incentives for initial investment, financing for research and development, and direct investment. With reference to renewables, a transition to hydroelectricity, in particular small-scale hydropower plants, could decrease long-term energy costs, aid in providing a secure energy supply and reduce the effects of climate change. Energy and natural resources are a critical component of any economy, and how they are used directly influences economic growth.

The use of thermostable lignocellulosic enzymes in a high-temperature process represents a number of advantages over their respective mesophilic counterparts, including increased solubility of the polymeric lignocellulosic substrates, enhanced enzyme processivity and reduced risk of bacterial and/or phage contamination during fermentation (Turner et al., 2007; Viikari et al., 2007). Alpha-L-arabinofuranosidases (AFases) participate in the deconstruction of lignocellulosic materials by hydrolysing the arabinofuranosyl bonds contained within the hemicellulosic portion of lignocellulose. In this study, three AFases isolated from compost-derived metagenomic DNA were characterised. Three genes derived from the fosmid metagenomic library constructed from 70°C compost were cloned into the pET21a(+) expression vector and expressed in E. coli BL21. The heterologously expressed proteins, AFase_H4, AFase_E3 and AFase_D3, were subsequently purified and their biochemical characteristics determined. All three AFases were shown to be active between pH 4.0 and 6.0. AFase_H4 and AFase_E3 displayed the highest activity at 60 °C, while AFase_D3 had an optimum temperature at 25 °C. Furthermore, the three AFases had differing thermostability profiles. In particular, AFase_E3 maintains 100% residual activity following 60 min incubation at 80 °C and 24 hour incubation at 60 °C. All three AFases have activity upon p-Nitrophenyl-arabinofuranoside and none against a range of alternative p-Nitrophenylglycosidic substrates. Phylogenetic analysis of the catalytic domain, identified within the amino acid sequences of the AFases, suggests that these AFases belong to glycoside hydrolase (GH) family 51. The difference in the AFase primary amino acid sequence motifs were used to infer differences in thermostability. All three AFases indicated similar biochemical and biophysical characteristics. AFase_E3 was determined to be the most thermostable amongst all three AFases. In the assessment of the three AFases respective suitability for inclusion in thermogenic bioethanol production processes, AFase_E3 was concluded as a suitable candidate for hydrolysis and synergistic testing on natural substrates. AFase_D3 possess the potential to be included in novel mesophilic industrialized process.

▼ The objective of this work is the creation of a framework for future priority-setting regarding the deployment of small modular reactor in isolated Northern energy grids. For this purpose this study uses a model-based approach, making use of the TIMES modeling environment. With energy being an absolute necessity in these regions, energy security is of the utmost importance. Currently, the most secure way of generating electricity comes mainly from diesel fuel. However, diesel power
comes at a high cost in the form of emissions, operational expenses and pollution. This puts an extreme financial burden on local communities and deters mining companies from investing in these inhospitable regions. The creation of the TIMES-Ring of Fire model makes it possible to analyze different scenario’s at the proposed Eagle’s Nest mine. Here, the proposed energy from diesel power is compared to multiple theoretical nuclear reactors. Small modular reactors prove to be competitive, however, they have a high level of uncertainty due to their limited data and experimental nature. With current assumptions, SMRs prove to be competitive between discount rates of 0-8%, and become increasingly competitive at longer energy-system lifetimes. The possible
introduction of a carbon tax increases SMRs competitiveness even further. Discount rates turn out to be a major variable in the assessment of SMR technology, as all investments are placed in
the first year, compared to diesel fuel which has most expenses in the future. Diesel fuel therefore is discounted more and has a relatively steady levelized cost of energy (LCOE). In contradiction, SMR LCOEs changes considerable with a varying discount rate. As a measure of competitiveness, the LCOE of nuclear power can drop to ∼ 31% of the comparable diesel system (20 year lifetime, linear carbon tax, 0% discount rate). This study, besides confirming past results, warrants future research and provides a flexible framework for this purpose.

▼ peer-reviewed
The valorisation of readily available and abundant lignocellulosic derived hexose carbohydrates by reaction with ethanol can provide an alternative to petroleum derived fossil fuels. The main barrier in effectively doing so is the lack of mechanistic knowledge regarding the reaction pathways linking the hexose sugar to the intended fuel component.
In pursuit of the chemical mechanisms responsible for the hydrolysis of; D-fructose, D-galactose, D-glucose, D-mannose to levulinic acid in aqueous systems using 2.5 wt% H2SO4 at 423 K is deciphered upon. The mechanistic comprehension gained is used as constraints to evaluate the more complex ethanolysis (ethanol/H2SO4/hexose) system. It is also comprehensively shown that formic and levulinic acids are not formed stoichiometrically from lignocellulosic derived hexoses, as is widely believed in the literature. At steady-state conversions of the reactant, the formic and levulinic acid ratio for D-fructose, D-glucose, D-mannose and D-galactose is shown to be 1.08 ±0.04, 1.15 ±0.05, 1.20 ±0.10 and 1.19 ±0.04 respectively.
Next, the ethanolysis process is introduced as a superior alternative to the aqueous hydrolysis systems. Two advantaged fuel components 5-ethoxymethylfurfural and ethyl levulinate are identified and numerical modelling is utilised to test the feasibility of carefully designed mechanistic propositions at 351 K catalysed by hydrogen cations. It is shown that the hydrogen cation is consumed by reaction with ethanol and that the overall system is ‘‘pseudo’’ catalytic. Condensed phase conditions (331-351 K) are deemed more suitable for the formation of 5-ethoxymethylfurfural, whilst biphasic conditions (>353 K) favours the formation of ethyl levulinate. A kinetic model is developed for the ethanolysis of D-fructose to 5-ethoxymethylfurfural (331-351 K), which includes kinetic contraints derived from conducting reactions with all key chemical intermediates in the system.
The reaction mechanism for the ethanolysis of D-glucose to ethyl levulinate (351-423 K) catalysed by H2SO4 (0.015-0.075) mol/L is deciphered upon, with no significant amounts of ethyl levulinate formed below 393 K. Significantly the main reaction flux for ethyl levulinate formation from D-glucose does not advance through any furan intermediates as it does in the D-fructose ethanolysis mechanism, which is not the proposed pathway in the literature. Finally, the fuel properties of the range of fuel molecules produced in ethanolysis systems are presented. It is shown that by integrating mechanistic understanding, kinetic parameters and fuel properties of the synthesized molecules, drop-in tailor-made fuel additives can be synthesized in a highly flexible “one-pot” process designed for specific purposes be it for ‘‘diesel’’ or ‘‘gasoline’’ fuels.

▼ This thesis evaluates the efficacy of carbon markets by assessing the impacts of the EU ETS and its links with the Kyoto Protocol’s flexibility mechanisms, the CDM and JI, on the socio-ecological, economic and political dimensions of climate change. The analysis of the relationship between the causes of climate change and the pollution movements, financial practices and policy debates that constitute these markets is developed by progressively introducing Marxist conceptions of the appropriation, commodification and capitalisation of nature, which organises the thesis in to three parts. The first part develops a critical understanding of the social relations, institutions and actors that produce climate change by appropriating carbon in capitalist economies. Mapping the organisation of capital and carbon to create a database of companies in the EU ETS reveals a concentration and centralisation of emissions among a relatively small number of publicly and privately owned corporations and large-scale power and manufacturing plants. The second part considers the processes that equalise differentiated relationships between installations and emissions, and offset projects and emissions reductions, in commodity form. Case studies of carbon allowance and credit networks associated with energy utilities RWE and E.ON illustrate the potential for the largest polluters to exploit unevenness in the production of climate change by trading transformative for marginal climate actions. The final part examines dynamics of accumulation and contestation in carbon markets in terms of the extent to which the capitalisation of carbon can support the expanded reproduction of capitalism. The crisis of the carbon market accumulation strategy and consolidation of the EU ETS in contestation over its reform are explained as outcomes of the contradictions faced by states in managing marketised environmental policy. Overall, the thesis argues that the EU ETS and its links with the Kyoto mechanisms have worked to entrench the production of climate change, necessitating a more efficacious and democratic approach to climate policy that directly targets the biggest corporate and state polluters.

▼ Fossil fuels are an important source of energy, however, are finite resources and highly polluters . Biodiesel comes as an important alternative energy as a renewable and cleaner, emitting fewer pollutants .The advantages of this biofuel, however, are hindered by their high oxidative instability. The high content of unsaturated allows the formation of free radicals, and biodiesel easily oxidized in the presence of light, heat, humidity or in contact with air. Antioxidants are an alternative to prevent or slow the degradation of biofuel. In this study, we evaluated the oxidative stability of B100 biodiesel from soybean oil at different temperatures in the presence of three commercial synthetic antioxidants, butylhydroxyanisole (BHA), butylhydroxytoluene (BHT) and tert-butylhydroquinone (TBHQ), pure or blended, from the experimental mixture of simplex-centroid, using the program Statistica v.9. The reaction order and rate constant were also calculated for all trials at 30, 50 and 80º C. By the Rancimat method used at temperatures of 100, 110, 120 and 130° C. The results, except at 120°C, showed that the treatment containing pure TBHQ proved to be the most effective, proven by design, the optimum mixture obtained and the rate constant. Binary and ternary mixtures containing TBHQ also showed appreciable antioxidant effect.
Os combustíveis fósseis são uma importante fonte de energia, porém, são recursos finitos e extremamente poluidores. O biodiesel surge como uma importante alternativa energética, sendo uma fonte renovável e limpa, emitindo menos poluentes. As vantagens deste biocombustível, no entanto, esbarram em sua alta instabilidade oxidativa. O alto teor de insaturações permite a formação de radicais livres, sendo o biodiesel facilmente oxidado na presença de luz, calor, umidade ou em contato com o ar. Os antioxidantes surgem como alternativa para impedir ou retardar a degradação do biocombustível. Neste trabalho, avaliou-se a estabilidade oxidativa de biodiesel B100 de óleo de soja em diferentes temperaturas na presença de três antioxidantes sintéticos comerciais, butilhidroxianisol (BHA), butilhidroxitolueno (BHT) e terc-butilhidroquinona (TBHQ), puros ou em mistura, a partir do delineamento experimental de mistura simplex-centróide, utilizando-se o programa Statistica v.9. A ordem de reação e a constante de velocidade também foram calculadas para todos os ensaios a 30, 50 e 80ºC. Pelo método Rancimat utilizou-se as temperaturas de 100, 110, 120 e 130ºC. Os resultados, exceto à 120ºC, mostraram que o tratamento contendo TBHQ puro mostrou-se o mais eficiente, fato comprovado pelos resultados obtidos do delineamento, pela mistura ótima obtida e pela constante de velocidade. Misturas binárias e ternárias contendo TBHQ também apresentaram apreciável efeito antioxidante.

▼ In this thesis various forms of scenario analysis are discussed both to
explore 1) how energy system and associated greenhouse gas emissions may
develop in the absence of climate policy and 2) how strategies aimed at
drastically reducing greenhouse gas emissions may turn out. As
uncertainties play a major role in long-term scenarios, the thesis also
discusses various forms of dealing with uncertainty in scenario analysis.
The thesis finds that global emissions are expected to continue to grow
under a wide-range of different assumptions in the absense of climate
policy. At the same time, the required reductions for reaching low
greenhouse gas concentrations levels consistent with a 2 degree Celsius
target are shown to be technically feasible within a likely range of direct
costs of 1-2% of GDP. However, this will require immediate action using a
broad range of options and worldwide participation in mitigating greenhouse
gas emissions. Possible crucial factors in determining the likelihood of
achieving ambitious climate targets include assumptions on technology
development and the possible links between climate policy and such related
issues as the reduction of air pollution.

The costs and benefits of low carbon technology options are unique and affect different market participants in different ways. In this thesis, we examine the cost effectiveness of carbon mitigation technologies and policies from the social perspective and from the perspective of consumers. In Chapter 2, we perform an engineering-economic analysis of hybridizing concentrating solar thermal power with fossil fuel. We examine the cost effectiveness of substituting the solar power for new coal or gas and find the cost of mitigation to be approximately ~130/tCO2 to ~300/tCO2. In Chapter 3, we quantify some externalized social costs and benefits of wind energy. We estimate the costs due to variability and transmission unique to wind to have an expected value of ~20/MWh. In Chapter 4, we quantify the cost effectiveness of a renewable portfolio standard and a carbon price from the perspective of consumers in restructured markets. We find that both that the RPS can be more cost effective than a carbon price for consumers under certain circumstances: continued excess supply of capacity, retention of nuclear generators, and high natural gas prices. In Chapter 5, we examine the implications of lowering electricity sector CO2 emissions in PJM through a Low Carbon Capacity Standard (LCCS). We estimate that an LCCS would supply the same amount of energy (105,000 GWh) as the RPS’s in PJM and an additional ~10 GW of capacity. We find that the LCCS could be more cost effective for consumers than an RPS if it lowered capacity prices.
