▼ The main heat sources of numerous district heating networks are unable to produce all required heat, due to fluctuating demand throughout seasons. Consequently, inefficient natural gas-fired boilers are often used to compensate for peak heat demand, while there is a surplus capacity or even surplus production of heat during summer. Seasonal
thermal energy storage can store heat from the main heat sources during summer and produce it at peak demand in winter, thereby increasing the
energy efficiency of district heating networks.
A promising technology to facilitate seasonal
thermal energy storage is high-temperature
aquifer thermal energy storage(HT-
ATES). After technical issues led to the shutdown of most HT-
ATES projects in the 1980s, there currently is renewed interest for HT-
ATES as proven solutions have since become available to the technical issues.
To facilitate its implementation, this thesis aims to develop a methodology for HT-
ATES potentials assessment and to identify the conditions, drivers and barriers for HT-
ATES implementation. Through literature research and brainstorm sessions with experts, the parameters relevant for HT-
ATES potentials were mapped and classified. Parameter values, formulas and boundaries were proposed and integrated in a methodology to design frameworks for the assessment of the theoretical, technical and market potential of HT-
ATES. The market potential assessment framework was applied to two quantitative case studies to illustrate the application of the frameworks and develop quantitative insights in conditions, drivers and barriers for implementation. A market potential of 14 kt of avoided CO2-emissions was found in Groningen; no market potential was found in the Rotterdam case study.
The potential assessment frameworks provide a step-by-step methodology that can be used in future research to fully quantify HT-
ATES potentials. The case studies revealed promising prospects for HT-
ATES in combination with geothermal heat and exposed shortcomings and weaknesses in the policy package in the Netherlands.

▼ Groundwater is potentially a useful source for storing and providing thermal energy to the built environment. In a nordic context, aquifer thermal energy storage, (ATES) has not been subject to a wider extent of research concerning environmental impact. This thesis intends to study the impact on groundwater chemistry from an ATES that has been operational since 2016 and is located in the northern part of Stockholm, on a glaciofluvial deposit called the Stockholm esker. Analysis of groundwater sampling included a period of 9 months prior to ATES operation as well as a 7 month period after operation and sampling was conducted in a group of wells in vicinity of the installation and within the system as ATES operation began. Means of evaluation constituted a statistical approach which included Kruskal-Wallis test by ranks, to compare the ATES wells with the wells in the surroundings and principal component analysis, (PCA), to study the chemical parameters that could be related to ATES. In addition, a geophysical survey comprising 2D-resistivity and induced polarization, (IP) was done to elucidate whether the origin of high salinity could be traced to nearby possible sources. The analysis was based on foremost the cycle of cold energy storage. The results showed large variations in redox potential, particularly at the cold wells which likely was due to the mixing of groundwater considering the different depths of groundwater being abstracted/injected from different redox zones. Arsenic, which has shown to be sensitive to high temperatures in other research showed a decrease in concentration compared to surrounding wells. There were found to be a lower specific conductivity and total hardness at the ATES well compared to their vicinity. That indicates that they are less subject to salinization and that no accumulation has occurred to date. It is evident that the environmental impact from ATES is governed by the pre-conditions in soil- and groundwater.

▼ Aquifer thermal energy storage (ATES) is a sustainable technology that provides thermal energy to buildings in temperate climates. The principle of ATES is to temporary store thermal energy in aquifers in a warm and cold well in order to use this thermal energy for heating and cooling in the next season. Because the available subsurface space is limited, congestion problems can occur in areas with high ATES density. In these areas a conflict of interests exists between private parties who want to achieve maximum efficiency by avoiding negative influence of other systems (leading to large buffers between wells), and the public interest to maximize the amount of thermal energy stored in the aquifer. One solution to this problem is to reduce the distance between wells of the same temperature, creating one large thermal zone around the wells. The main goal of this research is to quantify the change in performance of ATES systems when their thermal zones are connected. The results of this research are as follows. Connecting the thermal zones of wells of the same temperature increases the thermal recovery efficiency of individual systems. This increase is between 8-15% for an average ATES system with a storage volume of 250.000 m³. It is even higher for smaller systems, 15-40% for a system with a storage volume of 50.000 m³. This is crease in efficiency is due to lower losses to the surroundings due to a lower area of the thermal zone compared to the volume of the thermal zone. The reduced distance between wells leads to an increase in pumping energy. Therefore an optimal distance between wells of the same temperature of 0.5 times the thermal radius is found. The distance between wells of opposite temperature should be larger than 3 times the thermal radius.

▼ All over Europe, the expansion of renewable energy sources is quickly proceeding, fueled by environmental and political motives. The power generated by renewables is heavily subject to the intermittency of the source, e.g. the availability of wind or solar irradiance. Consequently, electrical grids that rely on renewable sources alternate between periods of excess power availability and periods with lack of power production. Excess power is often curtailed or exported, whereas the shortage of power production must be imported or produced through the deployment of more expensive production units. Power-to-X strategies aim to utilise the excess power from renewables more effectively, by converting power to another energy carrier within the grid, e.g. heat or hydrogen. By allowing the transition of power to another energy carrier, the system is transformed into a so-called multi-energy system. Therefore, the system takes into account the multiple energy carrier's system characteristics and loads in an integrated way. This formulation allows for optimal scheduling of energy flows in the system while taking into account characteristics of each energy carrier, e.g., storage characteristics, time-varying costs or production emissions. The main focus of this thesis to deal with the tasks of an energy management system for the aforementioned system using Model Predictive Control. The Model Predictive Control framework allows real-time optimal scheduling while incorporating data-driven forecasts of future loads and generation in the grid. Due to the stochastic nature of these forecasts, this thesis also looks into extensions of Model Predictive Control that can cope with uncertainties. Furthermore, to handle the different timescales of the grid dynamics, Model Predictive Control for multi-timescale systems is investigated. In particular, the performance of a Heuristic Model Predictive Control scheme and a Hierarchical Model Predictive Control scheme on the control of a simulated Power-to-X based energy system are compared. The simulation is based on a conceptual Power-to-X system based on historical data of the Dutch energy sector. Based on this case study, a statement is made about the suitability of the Power-to-X principles to future Dutch sustainable neighbourhoods. Moreover, a statement regarding the economic viability of the presented concept is made based on the simulations.

▼ Underground thermal energy storage (UTES) is an efficient technique to fulfill the heating and cooling demand of buildings. UTES uses stable subsurface temperatures store and extract energy. This study covers two types of UTES systems: aquifer thermal energy systems (ATES) and borehole heat exchangers (BHE). UTES systems in the Netherlands have seen a significant growth over the past years (Bloemendal, 2018) and are expected to contribute up to 20% of the heating and cooling demand of buildings by 2050 (Naber et al., 2016). As more UTES systems are installed, the risk of unwanted interaction between different system increases. However, ATES-BHE interaction is largely unknown. The objective of this study is to gather more insight in the interaction of ATES system on the efficiency of BHE systems. A numerical model is used to simulate an ATES well near a BHE system using SEAWAT (Langevin et al., 2008). The model is used to run different simulations, from which the efficiency of a BHE system is computed under different circumstances over a five year period. Four conclusions are drawn from the results. First, groundwater and temperature interference from ATES systems affect the efficiency of a BHE system differently. Simulations show that the effect of groundwater flow induced by an ATES system always has a positive effect on the efficiency of a BHE system. The effect of temperature interference is dependent on the temperature of the ATES well. Groundwater was also found to interfere at larger distances between both systems compared to temperature. Second, the degree of interference is related to the distance between the ATES and BHE system. For distances smaller than 0.5 times the thermal radius of the ATES system, interference from temperature was found to be dominant in the simulations. For distances larger than 0.5 times the thermal radius of the ATES system, groundwater interference was found to be the dominant factor. The third conclusion is that the depth placement of the ATES well screen has little to no effect on the amount of interference on the BHE system. Fourth, it is important to realize that no energy is spontaneously generated or lost as BHE efficiencies increase or decrease respectively. Energy is simply exchanged between the ATES and BHE system through the subsurface. Whether that is disadvantageous depends on the energy demands of both systems. Most energy demands are imbalanced, meaning either cooling or heating demand is larger than the other. It is recommended to consider UTES system installations from a holistic point of view.

▼ Aquifer Thermal Energy Storage (
ATES) systems provide sustainable space heating and cooling for buildings. In future, many buildings in moderate climates rely on
ATES for their space heating and cooling. However, the subsurface space available for heat
storage is limited and, there is a trade-off between individual
ATES system efficiency and minimizing greenhouse gas emissions in an area by facilitating as much
ATES systems as possible. Therefore, is it important to explore how aquifers can be utilized sustainably and to its full potential to maximize
energy saving with
ATES. In this dissertation methods for design, governance and planning of
ATES systems in busy areas are presented. It is also identified where in the world suitable aquifers and climatic conditions coincide with urban areas; the future hot-spots for
ATES, where these methods are needed. The presented design methods result in more efficient use of the subsurface and lower heat losses during
storage for individual systems. The results also show that in areas with many buildings with
ATES, the developed mathods for governacne and planning of
ATES wells result in much larger
energy savings by sustainably accommodating more
ATES system than is done and allowed in current practice.

▼ Seasonal
Aquifer Thermal Energy Storage (SATES) is an increasingly popular type of renewable
energy. Hereby summer heat and winter cold is stored in the subsurface for use in the opposite seasons. SATES systems are realized in high density in urban areas, where large amounts of contaminants are present. It is not fully understood to what extent interactions between the different SATES systems cause spreading of contaminants and to what extent SATES systems are a threat for the water quality, as groundwater protection zones are often present close by the urban area. In this study, analytical solutions, a theoretical model and a case study model of the city of Utrecht are used to describe, quantify and explain contaminant spreading in a high density SATES system area. Furthermore, these results are used to place the effects it in a regional perspective.
Model simulations showed that SATES systems contribute significantly to contaminant spreading, by two mechanisms.
1. Recirculation is the extraction of (contaminated) water by a SATES well and re-injection in the other SATES well. More wells within a SATES system and a larger distance between the extraction and injection wells increase the spreading effect of recirculation. As there is no straightforward way to model recirculation, the most realistic method, cross coupling of wells, is chosen out of several options.
2. SATES induced head changes increase spreading significantly, also in the vertical direction, and contribute to contamination dilution from a dense non-aqueous phase liquid (DNAPL).
Interaction between SATES systems is determined by overlapping capture zones. SATES induced head changes enlarge capture zones and increase the hydrological interaction of SATES systems. This results in more contaminant spreading.
Spreading is increased in such a degree, that on a timescale of decades all contaminations in a cluster of SATES systems are mixed to a single contamination plume. Contaminant travel times within a SATES system area are very small, but a buffer zone without SATES systems between the contaminated area and drinking water wells can extend the travel time significantly. In a regional perspective, other extraction wells (e.g. on building sites) are at least as important for the water quality as SATES systems, because of their purely extracting character and their much larger discharge.
This study shows how contaminant spreading is significantly increased in a high density SATES system area. It provides hands-on analytical relationships to describe the impact of several well variables on the amount of spreading. Besides, this report contains methods to properly model SATES specific processes that affect contaminant spreading. Also, the modeled contaminant spreading is placed in a larger perspective. Future research should focus on how this knowledge can be applied in regional subsurface planning.

▼ Aquifer thermal energy storage (
ATES) is a growing technology in the Netherlands. There are two kinds of
ATES configurations the doublet and the single borehole
ATES (SB-
ATES) layout. The limited subsurface space in combination with the lower construction cost and the lower performance of the SB-
ATES lead to the need to optimize their design. This master thesis focuses on gaining a better insight in the processes that occur around this configuration. Specifically, how anisotropy influences the efficiency of the design and what the optimal distance between filter screens is, in order to limit the interference between the screens, as it has a negative impact on system performance. To meet these two objectives, an axisymmetric numerical model was developed in a MATLAB environment, using MODFLOW and MT3DMS or SEAWAT groundwater flow and transport simulators. The simulation of heat advection was conducted applying the finite different method (FD method), it was the only method compatible with axial symmetric models that produced consistent results. As the FD method is subjected to numerical dispersion, three different grid resolutions were tested that were the 0.25, 0.50 and 1.00 m, respectively. The finest grid was decided to be used in the elaboration, as it gave the most accurate results compared to larger thickness width grid cells. Capacity test and borehole profile data were used to calibrate the overall vertical anisotropy of the case-studies. The capacity test allowed the calibration of one hydraulic parameter, for which the overall vertical anisotropy was chosen. The Kozeny-Carmen equation was used to calculate the hydraulic conductivity of each soil layer. This overall vertical anisotropy even though was estimated roughly, can be used to determine the presence of overlooked clay layers during the drilling of the borehole (anisotropy <<2) or whether high permeable layers are between the screens (anisotropy >>10). A sensitivity analysis was applied to estimate the optimum distance between the filter screens. Three different types of SB-
ATES, called GT15xx, GT20xx and GT25xx, were examined separately. The numbers indicate the installed pump capacity in m3/h while their mean and representative screen lengths are 5, 7 and 10m respectively. For the sensitivity analysis, three discharge fractions, Qfrac, were tested with values 0,25, 0.50 and 1.00 and three anisotropy values of 2, 5 and 10, these values are representative for sandy soils. The simulation time was 5 years, which was sufficient to the recommended efficiencies. The results showed that the maximum efficiency is practical independent of system type. The optimum separation distance for an anisotropy of 2 is respectively, 25, 30 and 35 m for Qfrac 0.25, 0.50 and 1.00. The evaluation of the sensitivity analysis was conducted, using real-scale case-studies and taking into account the distribution of conductivities along the layers. The available 18 case-studies were examined in terms of efficiency; it was found that a thin resistance layer between the screens,…

▼ This study introduces a new concept of
ATES system, which is called ATEST system, to fulfill the transport function while crossing the barriers in water transmission and pipe replacements. Firstly, analytical models were used to help understand the physical process and range the working conditions of the ATEST system. Then numerical models were used to prove the feasibility and the value of this new conceptual system. Acceptable system performance that can meet the heat demand was iterated in case simulation; and the economical advantages were identified by comparing it with traditional
ATES systems. The ATEST system showed a greater practical value than the
ATES system in: 1) solving the discrepancy between heat service and heat demand in space, and 2) crossing barriers where pipes cannot be buried. However, the system should be further modified in operation to acquire better performance and avoid practical problems.

▼ The focus of this project is the storage of thermal energy in packed beds for bulk electricity storage applications. Packed beds are composed of pebbles through which a heat transfer fluid passes, and a thermodynamic model of the heat transfer processes within the store is described. The packed beds are investigated using second law analysis which reveals trade-offs between several heat transfer processes and the importance of various design parameters. Parametric studies of the reservoir behaviour informs the design process and leads to a set of design guidelines. Two innovative design features are proposed and investigated. These features are segmented packed beds and radial-flow packed beds respectively. Thermal reservoirs are an integral component in a storage system known as Pumped Thermal Energy Storage (PTES). To charge, PTES uses a heat pump to create a difference in internal energy between two thermal stores; one hot and one cold. The cycle reverses during discharge with PTES operating as a heat engine. The heat pumps/engines require compression and expansion devices, for which simple models are described and are integrated with the packed bed models. The PTES system behaviour is investigated with parametric studies, and alternative design configurations are explored. A multi-objective genetic algorithm is used to undertake thermo-economic optimisations of packed-bed thermal reservoirs and PTES systems. The algorithm generates a set of optimal designs that illustrate the trade-off between capital cost and round-trip efficiency. Segmentation is found to be particularly beneficial in cold stores, and can add up to 1% to the round-trip efficiency of a PTES system. On the basis of the assumptions made, PTES can achieve efficiencies and energy densities comparable with other bulk electricity storage systems. However, the round-trip efficiency is very sensitive to the efficiency of the compression–expansion system. For designs that utilised bespoke reciprocating compressors and expanders, PTES might be expected to achieve electricity-to-electricity efficiencies of 64%. However, using compression and expansion efficiencies typical of off-theshelf devices the round-trip efficiency is around 45%.

▼ For decades, load shifting control, one of the most
effective peak demand management methods, has attracted attention
from both researchers and engineers. Various load shifting controls
have been developed and introduced in mainly commercial buildings.
Utility companies typically penalize consumers with “demand rates”.
This along with increased population and increased customer energy
demand will only increase the need for load shifting. There have
been many white papers, thesis papers and case studies written on
the different types of Thermal Energy Storage and their uses.
Previous papers have been written by Engineers, Manufacturers and
Researchers. This thesis paper is unique because it will be
presented from the application and applied perspective of the
Facilities Manager. There is a need in the field of Facilities
Management for relevant applications. This paper will present and
discuss the methodology, process applications and challenges of
load shifting using (TES) Thermal Energy Storage, mainly ice
storage.

▼ In the subsurface beneath the campus of Apeldoorn Achmea, the groundwater flow velocity is high. This causes a problem for its
Aquifer Thermal Energy Storage (
ATES) system: Infiltrated water with
thermal energy may be lost from the systems range if it is extracted with the accustomed control strategy. In this research project, an analytical model was built in an Excel work sheet, to quantify the
thermal energy distribution within the subsurface under influence of infiltration and extraction by 2 hot wells and 2 cold wells. This quantification should help to gain insight in how to smartly manage
thermal energy distribution through varying infiltration and extraction rates.
Studying the physical processes concerning
ATES, geohydrological subsurface characteristics, and
ATES system characteristics led to the creation of the analytical model in which a variety of problem related parameters can be adjusted and ultimately the infiltration and extraction rates can be adapted. The analytical model is validated qualitatively and with the numerical groundwater modeling program PMWIN.
Optimization of the accustomed infiltration and extraction rates is performed according to 3 strategies. The results of these 3 strategies are judged on its quality with a set of assessment criteria. This resulted in a chosen 'useful optimized control strategy' which reduced
energy loss from the system through varying the infiltration and extraction rates. This 'optimized control strategy' showed to be very robust.

▼ The building sector currently accounts for approximately one-third of the global demand for
energy, and one-fifth of all
energy-related greenhouse gas emissions (GHG). The development and adoption of
energy-efficient technologies in this sector is therefore a key element towards efforts for the mitigation of climate change. In particular, heating is the single largest end use of
energy in buildings; basic trends towards urbanization, as well as climate change, are also expected to significantly increase the demand of
energy for cooling by the middle of the century.
Energy technologies which can address both of these aspects are thus particularly promising. In this context,
Aquifer Thermal Energy Storage (
ATES) is an increasingly popular shallow geothermal
energy technology. This method uses natural
aquifer formations to seasonally store
energy for heating and cooling, using “warm” and “cold”
storage wells combined with a heat pump. This approach can reduce
energy demand by more than half in larger buildings.
ATES is used in nearly one-tenth of new commercial and utility buildings in the Netherlands, where suitable aquifers – combined with increasing demand for
energy-efficient technologies – make the technology especially competitive. However, this growth has already...

▼ As the worldwide energy demand continues to increase, scientists and engineers are faced with the increasingly difficult task of meeting these needs. Currently, the major energy sources, consisting of oil, coal, and natural gas, are non-renewable, contribute to climate change, and are rapidly depleting. Renewable technology research has become a major focus to provide energy alternatives which are environmentally-friendly and economically competitive to sustain the future worldwide needs. Thermal energy storage using adsorption is a promising technology which can provide energy for heating and cooling applications using solar and waste heat sources. The current work aims to improve adsorption systems to provide higher energy outputs and therefore, more economical systems. New adsorbents and operating conditions were tested with the goal of storing the available energy more efficiently. A model was also developed to gain a better understanding of the adsorption system to improve this developing technology.

▼ The objective of this research was to measure the effect of
thermal cycling on the nanoparticle distribution and specific heat of a nanocomposite material consisting of a eutectic of lithium carbonate and potassium carbonate and 1% by mass alumina nanoparticles. The material was subjected to
thermal cycling in a stainless steel tube using a temperature controlled furnace. After
thermal cycling, the stainless steel tube was sectioned into three equal parts – top, middle and bottom. Composite material samples were taken from the central region and near the wall region of each section.
The specific heat of this material in the temperature range of 290°C-397°C was measured using the Modulated Differential Scanning Calorimeter (MDSC) method. The concentration of alumina nanoparticles in this material was measured using neutron activation analysis. The average specific heat of the uncycled material was found to be 1.37 J/g°C.The average specific heat of the thermally cycled material was between 1.7-2.1 J/g°C. It was found that the concentration of the nanoparticle varied along the height of the sample tube. The nanoparticles tended to settle towards the bottom of the tube with
thermal cycling. There was also migration of nanoparticles towards the wall of the sample tube with
thermal cycling. Despite these gross movements of nanoparticles, there was no significant change in the specific heat of the nanocomposite due to
thermal cycling.

▼ The focus of this project is the storage of thermal energy in packed beds for bulk electricity storage applications. Packed beds are composed of pebbles through which a heat transfer fluid passes, and a thermodynamic model of the heat transfer processes within the store is described. The packed beds are investigated using second law analysis which reveals trade-offs between several heat transfer processes and the importance of various design parameters. Parametric studies of the reservoir behaviour informs the design process and leads to a set of design guidelines. Two innovative design features are proposed and investigated. These features are segmented packed beds and radial-flow packed beds respectively. Thermal reservoirs are an integral component in a storage system known as Pumped Thermal Energy Storage (PTES). To charge, PTES uses a heat pump to create a difference in internal energy between two thermal stores; one hot and one cold. The cycle reverses during discharge with PTES operating as a heat engine. The heat pumps/engines require compression and expansion devices, for which simple models are described and are integrated with the packed bed models. The PTES system behaviour is investigated with parametric studies, and alternative design configurations are explored. A multi-objective genetic algorithm is used to undertake thermo-economic optimisations of packed-bed thermal reservoirs and PTES systems. The algorithm generates a set of optimal designs that illustrate the trade-off between capital cost and round-trip efficiency. Segmentation is found to be particularly beneficial in cold stores, and can add up to 1% to the round-trip efficiency of a PTES system. On the basis of the assumptions made, PTES can achieve efficiencies and energy densities comparable with other bulk electricity storage systems. However, the round-trip efficiency is very sensitive to the efficiency of the compression–expansion system. For designs that utilised bespoke reciprocating compressors and expanders, PTES might be expected to achieve electricity-to-electricity efficiencies of 64%. However, using compression and expansion efficiencies typical of off-theshelf devices the round-trip efficiency is around 45%.

▼ This research examined what mix of building types result in the most efficient use of a technology known as Aquifer Thermal Energy Storage (ATES). Hourly energy simulation models for six different building archetypes were created based on representative building characteristic and energy use data from the Toronto area. A genetic algorithm optimization tool was then created to vary scheduling and production properties of the ATES system and the relative number of different building archetypes. The tool found that a cooling season from weeks 16‐42 maximized the useful energy output of the ATES and resulted in roughly 30% reduction in heating and cooling energy use and associated GHG emissions. It was also found that creating a mix consisting of a higher percentage of larger buildings than is currently found in most neighbourhoods could reduce energy usage by an additional 10%.

▼ Solar thermal energy harvesting is a promising solution to offset the electricity demands of a growing population. The use of the technology is however still limited and this can most likely be attributed to the capital cost and also the intermittent nature of solar energy which requires incorporation of a storage system. To make the technology more attractive and effective, cheap means of harvesting solar energy and the development of efficient and inexpensive thermal energy storage devices will improve the performance of solar energy systems and the widespread use of solar energy. Heat storage in a packed-bed rock with air as the working fluid presents an attractive and simple solution for storing solar thermal energy and it is recommended for solar air heaters. A packed-bed rock storage system consists of rocks of good heat capacity packed in a storage tank. The working fluid (air) flows through the bed to transfer its energy. The major concern of the design for a packed-bed rock thermal storage system is to maximize the heat transfer and minimise the pressure drop across the storage tank and hence the pumping power. The time duration the stored energy can be preserved and the air flow wall effect through the bed are the common complications encountered in this system. This study presents an experimental and analytical analysis of a vacuum storage tank with the use of expanded perlite for high temperature thermal energy storage in a packed-bed of rocks. Dolerite rocks are used as the storage medium due to their high heat capacity and as they are locally available. To minimise the pressure drop across the tank, moderate rock sizes are used. The tank contains baffles, allowing an even spread of air to rock contact through the entire tank, therefore improving heat transfer. There is a good correlation between the predicted and the actual results (4 percent) which implies that the baffles incorporated inside the vacuum tank forces the air through the entire tank, thereby resulting in an even lateral temperature distribution across the tank. The investigation of heat loss showed that a vacuum with expanded perlite is a viable solution to high temperature heat storage for an extended period. The research also focuses on the investigation of a proposed low cost parabolic trough solar collector for an air heating system as shown in Figure (1.3). The use of a standard solar geyser evacuated tube (@R130 each) has cost benefits over the industry standard solar tubes normally used in concentrating solar power systems. A mathematical was developed to predict the thermal performance of proposed PTC and it was found that the measured results compared well with the predictions. The solar energy conversion efficiency of this collector is up to 70 percent. This research could impact positively on remote rural communities by providing a source of clean energy, especially for off-grid applications for schools, clinics and communication equipment. It could lead to a significant improvement in the cost performance, ease of installation…

▼ One of the main challenges in the implementation of renewable energy is the mismatch between supply and demand. Energy storage has been identified as one of the solutions to the mismatch problem. Among various storage technologies, thermal energy storage (TES) is foreseen to have a significant role to achieve a low carbon energy systems because of the large share of thermal energy demand and its relatively low cost. However, integrating TES into energy systems requires careful design and implementation since otherwise potential financial and environmental savings may not be achieved. Computational-based design tools are ubiquitous in the design process of modern energy systems and can be broadly categorised into two methodologies: optimisation and simulation. In both cases, designing an energy system with storage technology is significantly more complicated than those without, mainly due to the coupling of variables between time steps. This thesis is concerned with two facets of the application of TES in energy systems. First, the role of TES in improving the performance of renewable-based domestic heating systems. Second, the implementation of optimisation and simulation tools in the design of energy systems with integrated TES. They are addressed by examining two case studies that illustrate the spatial and temporal variance of energy systems: a single dwelling heat pump system with a hot water tank, and a solar district heating system with a borehole thermal energy storage. In the single dwelling case study, the technical and financial benefits of TES installation in a heat pump system are illustrated by the optimisation model. A simulation model which utilises the optimisation results is developed to assess the accuracy of the optimisation results and the potential interaction between the two methodologies. The solar district heating case study is utilised to highlight the potential of a time decomposition technique, the multiple time grids method, in reducing the computational time in the operational optimisation of the system. Furthermore, the case study is also employed to illustrate the potential of installing a similar system in the UK. The latter study was performed by developing a validated simulation model of the solar district heating system. The findings of the analyses reported in this thesis exemplify the potential of TES in a domestic and community-level heating system in the UK. They also provide a basis for recommendations on the improved use of optimisation and simulation tools in the design process of energy systems.

▼ The increase in peak electricity demand in recent years has stressed the importance of peak electricity demand shifting technologies. Phase Change Materials (PCMs) have a potential to improve the building envelope by increasing the
thermal mass as well as contribute to a significant peak shift in whole building power demand. Therefore, special attention is given to properly capture the
thermal behavior of PCMs in advanced building
energy modeling software. Design of effective PCM
thermal storage systems requires accurate
energy modeling. There are analytical and numerical models developed during last few decades for this purpose, many have not been fully validated. Based on the current status of literature, the study identifies the limitations and drawbacks of existing methods. A parametric study is conducted to identify the optimum PCM thermo-physical properties, PCM locations in building envelope, under forced convection and a 5 hour pre-cooling strategy. Furthermore, an improved advanced numerical building envelope model is created in MATLAB to simulate the PCM performance in building envelope and an experimental apparatus is constructed to obtain useful experimental data for PCM included wall assemblies for validation purposes. This thesis also uses two datasets from laboratory studies of shape-stabilized and field studies nano-encapsulated PCMs to validate and compare PCM modelling algorithms of 6 modules in 5 building
energy modelling software. Finally, two macroencapsulated PCMs (Bio based PCM and hydrate salts) are tested using the experimental apparatus to obtain data for validation purposes. To approximate the heat transfer through a wall assembly with PCM pouches several techniques are investigated that can capture 3D heat transfer characteristics. Method with the highest agreement is used to validate and compare the developed MATLAB algorithm and different building
energy modelling software.

▼ High temperature
aquifer thermal energy storage (HT-
ATES) can potentially solve the mismatch between heat supply and demand. It can provide a large scale seasonal heat
storage solution. Thereby it enables an increase in full load hours of the base heat source, which can benefit project performance on both costs and emissions. However, the limited number of successful pilot projects indicates the technology has not escaped its state of infancy. There is a gap from concept to implementation, which is signified by the disagreement of experts on performance drivers and barriers of HT-
ATES. This research aims to narrow the described knowledge gap, by improving identification of HT-
ATES performance drivers and barriers. Thereby it strives to improve decision making of HT-
ATES implementation, and further enhance future HT-
ATES application in heating projects. The broad scope of research demands both a diagnostic and design-orientated approach, and fits seamlessly with a multi-criteria decision analysis. The analysis entails the stages of creating, evaluating, comparing and ranking of case-specific scenarios. Parametric variation changes the conditions for HT-
ATES implementation across the scenarios. A simulation model is developed and connected to a groundwater model to apply the parametric variation, to create the different scenarios, and consequently to produce the quantitative information for further evaluation. During the stages of creating, evaluating, comparing and ranking, the methodology systematically produces new results on the opportunities and risks introduced by HT-
ATES, and additionally on the HT-
ATES performance drivers and barriers. The results show that HT-
ATES enables the opportunity of improving project performance with respect to the internal rate of return and emissions. Groundwater impact remains the greatest risk, but it can be minimised with smart decision making. To support the decision maker and to overcome the risk of groundwater impact, the research proposes several performance-enhancing, non-explicit guidelines. The guidelines focus on realising an HT-
ATES implementation, where project performance with respect to internal rate of return, emissions and groundwater impact are balanced. Thereby they explain the major HT-
ATES performance drivers and barriers. The guidelines are summarised below. The decision maker is recommended to .. 1. .. minimise the uncertainty, through thorough subsurface characterization before implementation. Secondly, to focus on aquifers with a minimum depth of 200 [m] and a minimum hydraulic conductivity of 5 [m/d] 2. .. assure network return temperatures during peak demand are below expected
storage temperatures 3. .. not consider project life-times exceeding 20 years 4. .. assure yearly maximum base source heat production is always lower than yearly consumer heat demand 5. .. to strive for a flat demand curve and apply peak-shaving, by means of, for example, variable heat prices Currently, the guidelines have the purpose of giving direction to the decision maker, but…

▼ Sweden is only utilizing half of the available excess heat. To utilize more of the excess heat a seasonal thermal energy storage could be implemented to store excessed heat from the summer when the demand is lower to the winter when the demand is higher. This can be achieved by an integration of a seasonal thermal energy storage to the district heating system. A seasonal thermal energy storage may also reduce the need of the system’s peak load, which often is economically costly and adversely affect the environment. The purpose of the paper is to investigate the possibility for Skövde Värmeverk to implement a seasonal thermal storage. The paper is performed by a literature collection and calculations are made by software programs. The result shows that it is technically possible to implement a pit thermal energy storage and a borhole thermal energy storage, but no outcome shows a profitability within 20 years. A pit thermal energy storage can replace the system’s peak load up to 79 percent and a borhole thermal energy storage up to 2,8 percent. The most suitable case for Skövde Värmeverk is to install a pit thermal energy storage with a storage capacity of 4 GWh.

▼ Na presente dissertação analisa-se a possibilidade de efetuar armazenamento de energia sob a forma de ar comprimido, vulgarmente designado por sistema CAES, na Marinha Grande.
A pesquisa petrolífera evidenciou a existência de um anticlinal bem definido nesta zona que pode constituir uma estrutura ideal para o CAES. Através da construção de um modelo geológico estático conclui-se que o reservatório mais favorável é constituído pela formação de Torres Vedras (Cretácico Inferior), em níveis saturados com água de elevada salinidade, compostos por grés argiloso, e com uma espessura de 52 metros.
Apesar das limitações dos dados existentes procura-se ilustrar conceptualmente o dimensionamento da componente subterrânea da central CAES na zona de estudo. Conclui-se que este reservatório pode armazenar 0,106 km3 de ar pressurizado a 61,64 bar e produzir 331,7 MWh de energia através de 7 poços verticais. Estima-se que os custos associados à componente de armazenamento geológico sejam de 34,1M €; “Hydrogeological characteristics of porous media for compressed air

Abstract:
This thesis adresses the possibility of developing a compressed air
energy storage system, commonly refered as CAES system, in Marinha Grande.
OIl exploration campaigns have highligthed the existence of steeped slopes anticline, an ideal structure for CAES, in this area. A static model of the geological sequence, made it possible to define a possible reservoir for compressed air
storage in the Torres Vedras formation (Lower Creataceous) in clayey sandtone layers saturated with high salinity groundwater, with an average thickness of 52 meters.
In spite of the limited data avilable, the design of the geological
storage component of a CAES facility is illustrated for the study area. Analytical solutions indicate that the selected reservoir sable to store up to 0,106 km3 of air compressed at 61,64 bar and produce 331,7 MWh of
energy from 7 vertical wells. The cost of the geological
storage component of the CAES facility are estimated at 34,1M €.

▼ In the context of the development of renewable energy sources in the U.K., and of the increase in anthropogenic atmospheric CO2, it is important to develop alternative ways of providing energy to the community. The shift to renewable sources of electricity comes to a cost: variable generation. At present, an important part of the renewable electricity capacity is being curtailed during low demand periods. One way to ensure that electricity supply matches demand is to store excess energy when it is available and deliver it when demand cannot be met by primary generation alone. Compressed Air Energy Storage (CAES) allows this storage. The aim of this project is to build upon existing knowledge on CAES using porous rocks (PM-CAES) to assess the technical feasibility for this storage technology to be developed offshore of the UK. The focus is on inter-seasonal storage. This assessment is undertaken by developing geological and power plant models to calculate the storage potential of offshore UK formations. Modelling of a conceptual aquifer air store enables approximations of the subsurface pressure response to CAES operations. These pressure changes are coupled with surface facilities models to provide estimates of both load/generation capacity and roundtrip efficiencies. Algebraic predictive models can be developed from the results of a sensitivity analysis of the store and plant idealised models. Screening of the CO2 Stored database, containing data on geological formations offshore of the UK (initially developed for CO2 storage), was then performed to estimate PM-CAES potential using the predictive models. The results suggest that there is substantial PM-CAES potential in the UK. Results indicate an energy storage potential in the range of 77-96 TWh, which can be released over 60 days. A geographic information system (GIS) study was then performed to identify the portion of the identified storage potential colocated with offshore windfarm. 19 TWh of the storage potential identified is colocated with windfarm and would be achievable at an average levelised cost of electricity of 0.70 £/kWh.

▼ An ASR metric and site rating index applied to over 120 municipal and
agricultural locations across Oregon, combined with comparison to case study data from
existing ASR sites, indicate that more than 50% of selected sites are hydrogeologically
suitable for ASR. The ASR metric is a ratio of
aquifer storage to the rate at which surface
water is available for injection, with a result greater than one indicating sufficient
aquifer
storage. The site rating index evaluates
aquifer hydraulic parameters as well as economic
and engineering factors, and produces a percentage of ideal conditions. While economic
and engineering factors can determine ASR feasibility, transmissivity, depth to static
groundwater level and the desired injection rate are the controlling hydraulic parameters
for hydrogeologic ASR suitability. However, these factors have a flexible relationship;
for example, high transmissivity can compensate for small depth to groundwater and vice
versa.
In Oregon, most existing ASR sites target Columbia River Basalt interflow zones,
where transmissivity is high and native groundwater quality is generally suitable for
drinking water. These units are also prone to groundwater decline due to over-pumping,
which essentially creates
storage for ASR. Results show that suitable potential sites
correspond predominantly with Columbia River Basalt, Quaternary and late Tertiary
sediments. Potential
aquifer storage identified by this study is approximately equal to Oregon's annual public water supply in the year 2000, or 5 x 10⁸ m³ (160 billion gallons
or 502,809 ac-ft). This suggests that ASR expansion in Oregon can significantly increase
public supply and provide flexibility in the timing of water availability.

▼ Total produced energy in the world is mostly consumed as thermal energy which is used for space or water heating. Currently, more than 85% of total thermal energy consumption is supplied from fossil fuels. This high consumption rate increases the depletion risk of fossil fuels as well as causing a tremendous release of hazardous gases such as carbon dioxide, carbon monoxide, sulfur oxides, nitrogen oxides and particulate matter that effects both environment and human health. Those drawbacks force humankind to search for new technologies, like renewables, to reduce fossil fuel dependency on thermal energy production.
Thermal energy storage in adsorbent beds is one of the resulting technologies. Adsorption is an exothermic process in which a fluid (adsorbate) diffuses into the pores of a porous solid material (adsorbent) and trapped into the crystal lattice. In this system, exothermic adsorption of water vapor from air is carried out by using hybrid adsorbent of activated alumina and zeolite. In previous studies, through literature review, this adsorbent was selected to be the most efficient adsorbent for this process due to its high water adsorption capacity, high heat of adsorption, and stability [Dicaire and Tezel, 2011]. In this study, previous studies started on this project was confirmed and pursued by trying to increase the efficiency of the process and confirm the feasibility and applicability of this system in larger scales.
In this thesis, various zeolite and activated alumina hybrid adsorbents with varying zeolite compositions were screened to find the most efficient adsorbent for thermal energy storage process that gives the highest energy density. Then, existing small column was replaced with a new one, which is 16 times bigger in volume, in order to confirm the feasibility of this process at larger scales. Applicability of on-off heat release in adsorption process was also investigated by conducting several on-off experiments at different on-off time periods. Moreover, exothermic adsorption process was modeled by doing mass and energy balances in the column, water accumulation balance in the pellets, and energy balance in the column wall. Validity of this model was confirmed by comparing it with experimental results at different column volumes, and at different volumetric flow rates. Finally, an overall plant design, capital cost and thermal energy price estimations were done for adsorption thermal energy storage plants for different storage capacities and payback periods.

▼ Metal hydrides are a group of important materials known as energy carriers for renewable energy and thermal energy storage. A concept of thermal battery based on advanced metal hydrides is studied for heating and cooling of cabins in electric vehicles. The system utilizes a pair of thermodynamically matched metal hydrides as energy storage media. The hot hydride that is identified and developed is catalyzed MgH2 due to its high energy density and enhanced kinetics. TiV0.62Mn1.5, TiMn2, and LaNi5 alloys are selected as the matching cold hydride. A systematic experimental survey is carried out in this study to compare a wide range of additives including transitions metals, transition metal oxides, hydrides, intermetallic compounds, and carbon materials, with respect to their effects on dehydrogenation properties of MgH2. The results show that additives such as Ti and V-based metals, hydride, and certain intermetallic compounds have strong catalytic effects. Solid solution alloys of magnesium are exploited as a way to destabilize magnesium hydride thermodynamically. Various elements are alloyed with magnesium to form solid solutions, including indium and aluminum. Thermodynamic properties of the reactions between the magnesium solid solution alloys and hydrogen are investigated, showing that all the solid solution alloys that are investigated in this work have higher equilibrium hydrogen pressures than that of pure magnesium. Cyclic stability of catalyzed MgH2 is characterized and analyzed using a PCT Sievert-type apparatus. Three systems, including MgH2-TiH2, MgH2-TiMn2, and MgH2-VTiCr, are examined. The hydrogenating and dehydrogenating kinetics at 300 �C are stable after 100 cycles. However, the low temperature (25 �C to 150 �C) hydrogenation kinetics suffer a severe degradation during hydrogen cycling. Further experiments confirm that the low temperature kinetic degradation can be mainly related the extended hydrogenation-dehydrogenation reactions. Proof-of-concept prototypes are built and tested, demonstrating the potential of the system as HVAC for transportation vehicles. The performance of the concept-demonstration-unit show both high heating/cooling power and high energy densities. An extended cycling test shows degradation on the performance of the system. To solve this problem, a metal hydride hydrogen compressor is proposed for aiding the recharge process of the system.
