▼ Wind generation presents variability on every time scale, which must be accommodated by the electric grid. Limited quantities of wind power can be successfully integrated by the current generation and demand-side response mix but, as deployment of variable resources increases, the resulting variability becomes increasingly difficult and costly to mitigate. In Chapter 2, we model a co-located power generation/energy storage block composed of wind generation, a gas turbine, and fast-ramping energy storage. A scenario analysis identifies system configurations that can generate power with 30% of energy from wind, a variability of less than 0.5% of the desired power level, and an average cost around $70/MWh. While energy storage technologies have existed for decades, fast-ramping grid-level storage is still an immature industry and is experiencing relatively rapid improvements in performance and cost across a variety of technologies. Decreased capital cost, increased power capability, and increased efficiency all would improve the value of an energy storage technology and each has cost implications that vary by application, but there has not yet been an investigation of the marginal rate of technical substitution between storage properties. The analysis in chapter 3 uses engineering-economic models of four emerging fast-ramping energy storage technologies to determine which storage properties have the greatest effect on cost-of-service. We find that capital cost of storage is consistently important, and identify applications for which power/energy limitations are important. In some systems with a large amount of wind power, the costs of wind integration have become significant and market rules have been slowly changing in order to internalize or control the variability of wind generation. Chapter 4 examines several potential market strategies for mitigating the effects of wind variability and estimate the effect that each strategy would have on the operation and profitability of wind farms. We find that market scenarios using existing price signals to motivate wind to reduce variability allow wind generators to participate in variability reduction when the market conditions are favorable, and can reduce short-term (30-minute) fluctuations while having little effect on wind farm revenue.

▼ The solar energy field has grown vastly in the past decades, and this trend seems to continue also in the future. But there is still a lot of work to be done in order to make solar energy competitive to other energy production systems. Because of this, there is constant research toward improving existing solar energy systems, and to find new materials to lower the initial cost and increase efficiency of energy producing units. Recently, a material called perovskite has received a lot of attention from the solar industry by potentially offering a cheap and efficient material for solar cell production. With efficiency increasing every year, this could potentially be the next dominant design for solar energy extraction. One of the main concerns brought up related to this new technology is the lead content of the perovskite solar cell. Because of the toxic nature of lead, and the potential of these cells to be produced in large quantities in the future, the possible impacts of lead to the environment have to be assessed. This thesis consists of life cycle assessment of a perovskite solar cell and comparison to the currently most used common solar cell, which is the silicon solar cell. Several parameters were varied in the study in order to see which processes that have the largest influence to the environmental performance. From the study, it was found that perovskite solar cells could be competitive with silicon solar cells from an environmental point of view if produced on a large scale. Management of lead use and emissions during the production process of perovskite cells had the largest impact on the results. If all of the lead used would be supplied from recycling, and emissions of lead from the cell itself during and after the use phase is completely prevented, perovskite cells show better environmental performance than silicon cells. Regarding manufacturing technology, the study showed that the blade coating technology is environmentally preferable over spin coating for large scale production of perovskite cells.

▼ With intermittent renewable power being integrated in the power system, which is targeted to increase in the future as countries attain their renewable energy goals, there has been increased concern over solving the problem of intermittency. Demand Side Management (DSM) is an energy management concept which targets the demand side of the energy system and has gained lot of attention in recent times because of its potential to solve the issue of intermittency. Load shifting is one of the DSM measures which intends at shifting the demand towards more favourable time periods. Electricity consumption in Swedish households holds a significant share of Sweden’s total electricity consumption (around 29%). The possibility of getting charged for consumed electricity on hourly cost basis in Sweden has also opened an opportunity for electricity consumers to reduce their electricity costs by managing their loads. This thesis work investigates the potential for DSM in the form of load shifting common residential electrical loads in Swedish households. The loads examined are dishwasher, laundry and water heater loads. The possible effect on the load curve at a national level is also analysed. Further analysis has been made to estimate possible monetary savings that can be attained by consumers through load shifting. An optimization model built on a GAMS platform is used to calculate a shifting of load in order to minimize yearly cost of consuming electricity. The model is based on linear and mixed integer programming which gives least-cost load curve as an output. The Swedish households are divided into various archetypes, and for each of these a monetary saving potential is calculated. The scaling up of the results from the model is done based on statistical data available for Sweden to calculate the load shifting potential on the national level. The results indicate a significant load shift potential with reduction in peak hours reaching 6% of the peak load. However, savings in monetary terms for individual households is quite modest (~100 SEK) pointing towards a low motivation for consumers to manage their loads. The results also show that the water heating load forms a large part of the load which can be shifted and this load shift is highly seasonal. Thus the overall potential depends upon level of hourly price fluctuation and the season.

▼ Lithium-ion battery technologies have always been accompanied by severe safety issues; therefore recent research efforts have focused on improving battery safety. In large part, the hazardous nature of lithium-ion batteries stems from the high flammability of liquid electrolytes. Consequently, numerous researchers have attempted to replace liquid electrolytes with nonflammable solid electrolytes in order to avoid potential safety problems. Unfortunately, current solid electrolytes are incapable of performing as effectively as liquid electrolytes in lithium-ion batteries due to inferior electrochemical capabilities. While some "all-solid-state" batteries have found niche application, further technological advancement is required for large scale replacement of liquid-based batteries. The goal of this research is to develop all-solid-state batteries that can outperform liquid batteries and understand the mechanisms that dictate battery operation and behavior. This involves fabrication of highly conducting solid electrolytes, production and analyzation of batteries employing state-of-the-art electrode materials, and generation of high power and high energy density lithium batteries. In this dissertation, the first objective was to manufacture highly conducting solid electrolytes that are stable in contact with lithium metal. Numerous characterization techniques were used to gain understanding of physical and chemical properties of solid electrolytes, as well as mechanisms for fast ion conduction. A new process for production of highly conducting and stable solid electrolytes is developed and materials are used to evaluate performance of electrodes in an all-solid-state construction. The second objective of this work was to research the performance of both positive and negative electrodes incorporating solid electrolyte. Evaluation of electrochemical results allowed for a good understanding of reaction mechanisms taking place within composite battery materials and at electrolyte/electrode interfaces. Variation of solid electrolyte make-up and composite electrode architecture reveals numerous advantages of solid state batteries over liquid batteries. The third and final objective of this work was to demonstrate high energy/power density all-solid-state rechargeable batteries. Electrode materials with fast lithium diffusion and kinetic properties were investigated. Alteration of particle size and testing temperature exposed the capability of solid state batteries to achieved high performance, comparable to that of liquid electrolyte batteries.

▼ Today 57.7 % of Nigerians has access to electricity with less than 1 % using electric stoves for cooking. Fuelwood is used for cooking in 63.7 % of the households and is one of the main contributors to Nigeria having the third highest deforestation rate in the world with 410 000 hectares of forest cut down per year. The country is also listed as one of the ten most vulnerable countries to climate change in the world. The main objective of this thesis is therefore to evaluatea key section of the integrated Climate, Land, Energy and Water system (CLEWs) nexus for Nigeria between 2015–2030 with the main CLEWs interlinkages focused on being the ones between energy (electricity & cooking), land (deforestation) and climate (CO2 emissions). The further aim of this thesis is to contribute in the UNDP’s work towards the SDG 7 (affordable andclean energy) and 15 (life on land). Through the modelling of 10 different scenarios in the long-term energy planning tool OSeMOSYS (Open Source Energy Modelling System) the outcomes of all scenarios are analysed and compared regarding costs and their implications on the deforestation rate and CO2 emissions. The results show that the scenarios with NREEEP leads to a 30 % reduction in CO2 emissions in Nigeria compared to those in the cost-optimized scenarios. The results on deforestation show that the forests in the country will be gone or almost gone by 2030 both in the cost-optimal scenarios as well as in the business as usual and high growth scenarios. The No fuelwood and charcoal scenario saved the most of the forests, but had the highest CO2 emissions which indicates that there is a conflict between SDG 7 and 15. For futurework it is recommended to expand the modelling work done in this study through, among other things, enforcing OSeMOSYS to create an optimal cooking sector based on environmental factors through the use of parameters such as emission penalty and implementing other types of innovative stoves in the model to analyse the outcomes.

▼ The objective of the present work is to improve the accuracy of Actuator Line Modeling (ALM) in predicting the unsteady aerodynamic loadings on turbine blades and turbine wake by assessing different methods used to determine the relative velocity between the rotating blades and wind. ALM is incorporated into a Large Eddy Simulation (LES) solver in OpenFOAM (Open Field Operations and Manipulations). The aerodynamic loadings are validated by experiment results from National Renewable Energy Laboratory (NREL). Turbine wakes are validated by predictions of large eddy simulation using exact 3D blade geometries from a two-blade NREL Phase VI turbine. Three different relative velocity calculation methods are presented: iterative process in Blade Element Momentum (BEM) theory, local velocity sampling, and Lagrange-Euler Interpolation (LEI). Loadings and wakes obtained from these three methods are compared. It is discovered that LEI functions better than the conventional BEM with iterative process in both loading and wake prediction. Then LES-ALM with LEI is performed on a small wind farm deploying five NREL Phase VI turbines in full wake setting. The power outputs and force coefficients of downstream turbines are evaluated. The LES-ALM with LEI is also performed on a small wind farm deploying 25 NREL Phase VI turbines with different inflow angles (from full wake setting to partial wake setting). The power outputs and force coefficients of each turbine are evaluated under different inflow angles (the angle the rotor has to turn to make the rotor plane face the incoming wind) (0, 5, 15, 30 and 45 degree). The power coefficient distributions and thrust coefficient distributions of the wind farm under each inflow angle are compared. The range of inflow angle which is best for power generation is also discussed. The results demonstrate that the LES-ALM with LEI has the potential to optimize wind farm arrangement and pitch angle of individual turbines. Advisors/Committee Members: Jun Chen, Jun Chen, J.

▼ This master thesis examine how a low temperature radiator systemcan be implemented in a new built office and what effects this will have on the return temperature. One point in the system was logged and data was collected. A model was then developed in VIP-Energy to determine the heating demand for an office building which were compared to the supply. A cost analysis was also performed on different types of low temperature radiator systems. These were compared to a conventional radiator system with a supply temperature of 55°C and a return temperature of 45°C. A cost analysis was also done on whether to build energy efficient or not. The study shows a strong correlation between the heat demand and the time of day. The demand is low during office hours and high during nights and weekends with a peak demand of 70 kW. The low demand is due to the high amount of process energy an office uses. The point in the system can supply the heat demand during almost every hour of the year. For the few hours where there is a mismatch between supplied heat and demand, a shunt solution can supply the return water with primary heat. If the heat demand is scaled up with ten or twenty identical houses the point will be unable to supply enough power to cover the heat demand for more hours a year. The most cost-effective radiator system is Purmo Belize with a supply temperature of 40°C and a return temperature of 30°C. Purmo Belize has built in fans that can improve the heat supply to the room with up to 80 %. Compared to a conventional radiator the payback time is 9 years, with a return on investment of 12,8 percent and a net present value of 151 762 kr. A 40/30°C-system will lower the return temperature in the measured point with 0,4°C. For the whole system this means a reduced temperature of 0,00003°C if the total flow is 50 m3/s and the average return temperature is 50°C. From a strictly economic point of view, an extra energy efficient house will be beneficial if the extra cost is up to 5 000 000 kr or around 700 kr/m2 with a depreciation time of 25 years.

Biokol har potential att vända trenden med ökande halter av koldioxid i atmosfären. Genom pyrolys formeras kolet i biomassan i stabil form i hundratals till tusentals år. Ett positivt klimatavtryck skapas genom att avskilja kol ifrån den snabba omsättning som förbränning och kompostering innebär. Biokolet har även jordförbättrande egenskaper genom sin porösa struktur och stora aktiva yta vilket kan nyttjas av både jordbruk, hobbyodling och urban grönstruktur. Stockholm har i ett innovativt projekt satt upp en pilotanläggning för biokolsproduktion införlivat i ett urbant flöde. Trädgårdsavfall ifrån villaträdgårdar matas in i biokolsanläggningen, värmen som alstras under processen växlas mot fjärrvärmenätet och biokolet delas ut till boende i staden samt används i stadens planteringar. Syftet med denna undersökning är att utvärdera betydelsen av biomassans bearbetning eftersom mängden energi och resurser som investeras i förbehandlingen påverkar projektets totala hållbarhetspotential. Genom att praktiskt testa detta kan användbar kunskap gagna biokolsprojektet och liknande projekt samt agera förstudie till vidare forskning och utveckling. Två olika bearbetade fraktioner av biomassa undersöktes empiriskt i anläggningen under driftens första månader. Analyser av biobränslen och producerat biokol utfördes av ett ackrediterat laboratorium och driftsfunktionen observerades. Fraktionerna bearbetades med olika metoder vilket medförde olika egenskaper. Den ena var av krossat biomassa där stor andel oorganiskt material följt med och den andra var huggen flis i dimensionen 30mm. Ingen av de testade fraktionerna fungerade tillfredställande i drift. Den krossade biomassan innehöll för mycket små partiklar vilket gav problem med valvning och matning. Hög askhalt och lågt värmevärde gjorde att mycket extern energi behövde tillföras. Den flisade fraktionen innehöll för många bitar som översteg 30mm vilket orsakade många driftstopp. Analysen visade på hög askhalt i den andra fraktionens biokol vilket kan tyda på att förbränning förekommit. Företeelsen bör undersökas närmare. På grund av ojämn drift och andra osäkerheter bör inte de resultat som balansräkningarna för kol och energi visar betraktas som representativa tal för utbyten i anläggningen, utan endast ligga till grund för diskussion, jämförelse och planering av fortsatta försök. Första prioritet för biokolsprojektet bör vara att finna en fungerande fraktion, exempelvis genom att sålla bort de minsta partiklarna ur krossat material eller att hugga fliset i mindre dimensioner. Därefter kan vidare undersökningar göras i syfte att justera systemet för att förbättra egenskaper hos biokolet och dess produktionsprocess.

Biochar has the potential to reverse the trend of increasing levels of carbon dioxide in the atmosphere. Biochar has soil&improving properties through its porous structure and large active area which can be used by agriculture, hobby cultivation and urban green structure.

▼ Genom att samhället utvecklas och bland annat strävar mot effektivare energianvändning, ökning av andelen förnyelsebara energikällor samt sänkta koldioxidutsläpp. Är det ofrånkomligt att energisystemen i samhället inte påverkas. Bland annat så krävs det inte lika mycket energi för att täcka byggnaders energibehov i dag än tidigare. Detta medför att energisystemen i samhället utvecklas och strävar efter att bli mer effektiva. I Sverige är fjärrvärmen den vanligaste uppvärmningsformen där mer än 50 % av alla bostäder och lokaler använder fjärrvärme som värmekälla. Fjärrvärmens grundtanke är mycket enkel och beprövad. Den går ut på att producera värme storskaligt vid ett eller flera värmeverk och distribuera värmen i två stålrör som ligger nedgrävda i marken ut till kunder som har värmebehov. När värmen når kunden genom framledningsröret finns där en fjärrvärmecentral som växlar värmen till fastighetens egna interna värmesystem. Det avkylda fjärrvärmevattnet pumpas då tillbaka i det andra röret (returledningen) till produktionsanläggningen för att återigen värmas upp. Genom åren har fjärrvärmen utvecklas, och ser man från de första fjärrvärmesystemen (generation 1) till dagens system (generation 3) har utvecklingen generellt varit att gå mot lägre temperaturer i systemen. Man menar nu att det är hög tid att gå från generation 3 till 4:e generationens system som generellt strävar efter att sänka temperaturerna ytterligare i systemen. Sänkta temperaturer gällande fjärrvärmesystem har visat sig ge positiva effekter gällande ekonomi, miljö och resursutnyttjande. Dels så ger sänkta temperaturer effektivare produktion eftersom mer el kan genereras i kraftvärmeverken och större andel rökgaskondensering kan användas samt att mer integrering av spill- och restvärme från industrier kan utnyttjas. Det finns olika förslag på hur man ska gå mot lägre temperaturer i systemen. Rapporten ämnar att undersöka om en ny fjärrvärmeteknik som kallas 4GDH- 3P kan vara lönsam att redan idag implementeras i befintliga fjärrvärmenät. Teknikens grundtanke är att förlägga 3 distributionsledningar istället för 2, detta för att kunna få ner temperaturerna samt spara energi och helt enkelt få mer effektiva system. Tekniken är i grunden till för nyanslutningar av lågenergihus och är under utveckling. I denna studie undersöks vilka möjligheter som finns i att ansluta ett exploateringsområde på 63 lägenheter i Borlänge. Kostnader jämförs, beräkningar på hur mycket energi som kan sparas samt vilka möjligheter det finns att sänka temperaturerna i nätet med hjälp av tekniken utreds. Resultaten visar att den nya tekniken är relativt dyr att bygga jämfört med att bygga på konventionellt sätt. I detta sammanhang visar det sig att investeringen av den nya tekniken uppskattas bli ca: 70 % dyrare än vanlig konventionell byggnation. Resultaten visar också att med den nya tekniken kan man teoretisk gå mot lägre returtemperaturer på uppemot 12,5 °C i en bestämd punkt i returledningen. Energibesparingen uppgick till 62,57 MWh under perioden…

Av Sveriges totala växthusgasutsläpp är det i nuläget transportsektorn som står för den största andelen och står för mer än 30 % av alla utsläpp. Med ett ökande fordonsbestånd och ett fortsatt behov av transporter blir lösningar som minskar utsläppen från denna sektor avgörande för Sveriges hållbara utveckling. Eftersom 93 % av Sveriges drygt 4,7 miljoner personbilar drivs av fossila bränslen skulle investeringar i alternativa färdmedel såsom elbilar kunna leda Sverige i rätt riktning. Författarna till denna rapport tror att, om man kan hitta ekonomiskt lönsamma lösningar för företag att investera i mer miljövänlig teknik, skulle det hjälpa samhället att tackla miljöproblemen. Det här projektet undersöker om elbilar med tillhörande solcellssystem för laddning kan vara en ekonomiskt och miljömässigt hållbar investering för ett företag. För att ta reda på detta skapades en fallstudie med specifika bilmodeller och en specifik solcellsteknik. Fallstudien delades upp i två framtidsscenarier för respektive bilmodell som förmånsbil. Detta för att kunna jämföra kostnad och miljöpåverkan under en 25-årsperiod. Den elektriskt drivna bilen som användes var Nissan Leaf 24 kWh och den bensindrivna var Mercedes-Benz A 180. Solcellerna var av typen CIGS (Copper Indium Gallium Sellenide) med en verkningsgrad på 12,3 %. Utifrån fallstudien skapades en beräkningsmodell i MatLab för att kunna göra specifika beräkningar på hur de olika alternativen stod mot varandra. Resultatet av studien visade att solcellerna inte kunde förse elbilarna med deras laddningsbehov under största delen av vinterhalvåret och el var tvunget att köpas in från det svenska elnätet. På sommarhalvåret var det istället en överproduktion av el som kunde utnyttjas av företagsbyggnaden. Elbilarna med tillhörande solcellssystem beräknades till att både vara mer ekonomisk och miljömässigt hållbara sett över hela 25-årsperioden. Elbilarna stod dock för det högsta utsläppet av de två bilmodellerna vid tillverkning medans bensinbilarna stod för det högsta vid drift. Elbilarna med solcellssystemet hade en dyrare ingångskostnad men bensinbilarna var väsentligt dyrare i drift. Det är svårt att generalisera resultatet från denna studie då den enbart undersöker ett fall med specifika antaganden och avgränsningar, men för att sätta fallstudien i ett större perspektiv måste en viss generalisering göras. Slutsatsen som kan konstateras är således att det generellt sett finns stor potential och rimliga möjligheter till att få det både lönsamt och miljövänligt att investera i elbilar med anknutet solcellssystem.

Of Sweden's total greenhouse gas emissions, the transport sector currently accounts for the largest proportion, accounting for more than 30% of all emissions. With an increasing vehicle stock and a continued need for transport, solutions that reduce emissions from this sector are crucial for Sweden's sustainable development. Since 93% of Sweden's more than 4.7 million passenger cars are driven by fossil fuels, investments in alternative means of…

▼ Sverige är ett av många länder som behöver bryta sitt beroende av fossil energi för att nånationella och globala klimatmål. Ett sätt att bidra till detta är genom ökad elektrifiering, att ersätta fossil energi med el. Rapporten är en förstudie till Kungl. Ingenjörsvetenskapsakademiens (IVA) kommande projekt “Elens roll för ökad hållbarhet” och lyfter fram lovande elektrifieringsinitiativ för att ge förståelse för den potential som elektrifiering kan ha på olika sektorer. Arbetet har utgått från två frågeställningar och ämnar till att besvara vilka elektrifieringsinitiativ som finns i Sverige inom transport- och industrisektorn och vilka konsekvensersamt potentiell reducering av landets klimatutsläpp olika elektrifieringsinitiativ kan ledatill inom respektive sektor. Rapporten har kartlagt 27 initiativ. Analys har gjorts på personbilar, tunga lastbilar, lätta lastbilar, arbetsmaskiner, bussar, järn och stålindustrin och kort kring övrig industri. En djupare analys på personbilar ger slutsatsen att även en ambitiös satsning mot 100% supermiljöbilar, elbilar och laddhybrider, inybilsförsäljningen år 2025 inte ger mer än 60% minskning i utsläpp från personbilar mellan 2015-2030. Det jämförs med dagens trend från beslutade åtgärder som ger 39% utsläppsminskningunder samma period. Många osäkerheter påverkar detta både positivt och negativt, där nybilsförsäljning med restriktioner, utsläpp från nordisk elmix, självkörande bilar, vilja och möjlighet att inte ha bil, utsläpp från elbilsproduktion och främjande av laddhybriderär några viktiga faktorer. En djupare analys för tunga lastbilar visar att två elvägsinitiativ, eHighway och eRoadArlanda,har potential att minska utsläppen från vältrafikerade vägar. Det är dock ingen lösningför alla tunga lastbilar, utan ytterligare initiativ eller minskade godstransporter behövs. Övriga analysen visade att utsläpp från lätta lastbilar är ett växande problem, arbetsmaskinerhar potential att göra stor påverkan globalt och bussar inte bidrar till stor utsläppsminskningmen kan vara nyckeln till att minska utsläppen från personbilar. I Järn- och stålindustrinfinns omfattande initiativ som på sikt kan minska utsläppen nästan helt, men projekten ärfortfarande så pass nya att det troligtvis inte kommer att ske stora förändringar innan 2020. Det finns stora vinster i att ligga först i utvecklingen mot ett hållbart samhälle eftersom exportmarknaden för grön teknik kan förväntas växa i framtiden. Det gör att svensk konkurrenskraft kan gynnas av att testa prototyper som sedan kan exporteras till andra länder. Rapporten avslutas därför med ett antal förslag på hur beslutsfattare kan fortsätta framåt. Den viktigaste av dessa är att teknikutveckling är en del av lösningen, men att ett större systemperspektiv behövs för att kostnadseffektivt minska utsläppen. Sammantaget så kommer målet om fossilfri fordonsflotta inte att nås till 2030, men många andra vinster kan göras av utvecklingen. Tydligare konkreta handlingsplaner behövs för att åstadkomma förändring och regeringen…

Sustainable, effective and affordable access to energy plays a significant role when it comes to improving people's living conditions, and supporting human and economic development. Therefore, the access and availability of electricity is an important factor and indicator of how well developed a country is. Furthermore, the generation of electricity is often strongly interlinked with other sectors such as climate, land use, and water. All these resources’ systems can have a certain effect on the energy production and vice versa. It is therefore a complex sector, and it needs to be developed with these interlinkages in mind. The aim of this project is to study and analyze the future electricity system in Ghana and its linkages to climate change and water resources. In this project, the modelling tools focus to optimize the electricity generation in consideration of economic values, as well as analyzing climate change and its impact on electricity generation by hydropower. To make a projection of the electricity system in Ghana, two modelling tools were used in the study, OSeMOSYS and ONSSET. The results generated by the models give an indication of potential optimal generation mixes between 2015 and 2050, for the different set of considerations on which the scenarios were built. The projected electricity generation consists of a combination of both renewable energy technologies and fossil fuel dependent technologies. The contribution from concentrated solar power (CSP) stands for the largest share of the mix in the long term. The results also suggest that climate change most certainly will have an impact on the electricity production in Ghana, due to its effect on the performance of hydropower production. This is an indication that Ghana’s reliance on hydropower for its electricity production, could not be sustainable and reliable in the long term. Ghana is an unequally developed country and there are still many undeveloped regions with poor access to electricity, especially in the northern parts of the country. There is also a rising demand of water and land for agricultural use. Since these resources also are important for the sustainable production of electricity, further and more detailed investigation of the conflicts between these sectors is necessary for a sound and compatible sectoral development and sustainable management of resources.

Hållbar, effektiv och prisvärd tillgång till energi och elektricitet är en viktig del i att förbättra människors livsvillkor och för stödja mänsklig och ekonomisk utveckling. Tillgången till elektricitet är på grund avdetta en viktig indikator på hur väl utvecklat ett land är. Vidare är produktionen av elektricitet stark sammankopplad med andra sektorer såsom klimatet, landanvändning och vatten, då alla dessa resurser påverkar energiproduktionen och vice versa. Energisektorn är därför mycket komplex och utvecklingenav den kräver att dessa kopplingar till andra sektorer respekteras. Syftet med det här projektet är att studera och analysera…

Electricity is a fundamental part a functioning society. Ghana’s electricity system is strained by an ever-growing climate instability and increase of population. Therefore, it is crucial for the country's development that it's electricity supply is done in a sustainable way. This report aims to analyze Ghana’s ability to reach SDG 7.1 and the Marrakech Vision, an outcome from the COP 22 meeting in Morocco. This was done by creating a model over Ghana’s electricity system and how it develops over time, called BAU, using the analytical tools: OSeMOSYS and OnSSET. A practical implementation of BAU was then discussed. After that, three development scenarios with different renewable energy targets for the electricity system, were implemented in the model. The results show that CSP and natural gas power plants were the most prominent electricity producers. The growing share of renewable energy in the target scenarios was mostly due to wind power, replacing the natural gas power plants. Ghana has local natural gas resources as well as high solar potential. The rising share of renewable energy limits the fossil fuel emission. At the same time, this increased share also endangers the reliability of the electricity supply, as the capacity of renewable energy resources fluctuate and could lead to high investment costs. BAU can be a possible solution which minimizes the fossil fuel consumption and limits the CO₂ emissions, but at the risk of possibly having an unreliable electricity supply. To be able to meet SDG 7.1, increasing the share of renewable energy in electricity generation can be a solution, but at the same time, not all requirements of the goal will be fulfilled.

Elektricitet är en grundläggande del av ett välfungerande samhälle. Ghanas elsystem påfrestas allt mer av skiftande klimat och växande befolkning. Därför är det oumbärligt för landets utveckling att elförsörjningen sker på ett hållbart sätt. Denna rapport syftar till att undersöka Ghanas förmåga att uppnå SDG 7.1 och Marrakech-visionen, vilken landet förband sig till under COP 22 mötet i Marocko. Detta genomfördes genom att utveckla en modell över Ghanas elsystem och dess utveckling, kallad BAU, med de digitala verktygen: OSeMOSYS och OnSSET. Därefter diskuterades dess genomförbarhet. Fortsatt undersöktes tre utvecklingsscenarier med olika mål för andel förnybar energi i elproduktionen, i modellen. Resultatet visar på att CSP och gaskraftverk var de mest framträdande elproducenterna. En stigande andel förnybar energi utspelade sig som en ökad elproduktion från vindkraftverk och minskad från gaskraftverk. Ghana besitter naturgastillgångar och hög solpotential. Den stigande andelen förnybar energi begränsar koldioxidutsläppen. Samtidigt kan den ökande andelen förnybar energi sätta pålitligheten i fråga då tillgången till sådan energi fluktuerar, och innebära höga investeringskostnader. Således kan BAU vara genomförbar sett till begränsning av koldioxidutsläpp, men kan eventuellt inte tillhandahålla tillförlitlig…

Rwanda is a small country in Central Africa with plans on 100% electrification and 60% renewable energy in the electricity mix by 2030. Today 31% of the country’s population has access to electricity and hydropower yields approximately half (44%) of the country’s electricity generation. The country’s plans include an aggressive development plan, which aims to foster multi-sectoral development and elevate the country from poverty. Water is a critical resource, heavily exploited by both the power and agriculture sector. This thesis intends to investigate the role of hydropower in Rwanda’s electrification plans, identify critical points in the use of water and explore the possible effects of climate change. Two energy modelling tools were used, namely OnSSET and OSeMOSYS. Water balance equations were developed manually based water demand data from the Rwandan Ministry of Natural Resources and three climate scenarios based on data from KNMI Climate Explorer. The results show that hydropower’s share is expected to vary between 7 - 47% in the electricity mix by 2030, with its penetration highly depending on both electricity demand and climate scenario selected. It was also concluded that water availability will not be able to sufficiently cover the expected water demand in the country after 2026. Hence, Rwanda’s aggressive hydropower expansion plans might need to be reconsidered.

Rwanda är ett litet land i centrala Afrika med mål att elektrifiera hela landet samt att ha en elmix med 60% förnyelsebart år 2030. Idag har 31% tillgång till el och vattenkraft står för 44% av elmixen. Vatten är emellertid en begränsad resurs med ökande behov från inte minst jordbruket. Denna rapport utreder vattenkraftens roll i Rwandas elektrifieringsplaner och klimatförändringars påverkan på vattentillgång. För att modellera elmixen har OnSSET och OSeMOSYS som är två modeller utvecklade på KTH dESA använts. Beräkningar på vattentillgänglighet har gjorts med hjälp av vattentillgång utifrån flera klimatscenarion samt prognoser av framtida vattenbehov från Ministry of Natural Resources i Rwanda. De framtagna resultaten visade att vattenkraften år 2030 bidrar med 7 - 47% till elmixen beroende på klimatscenario och elbehov. Denna variation beror dock framförallt på skillnaderna i de årliga variationerna i nederbördsmönster mellan olika klimatscenarion snarare än minskad total vattentillgång pga klimatförändringar. Oberoende av klimatförändringarna kommer vattentillgången inte kunna täcka det uppskattade vattenbehovet och de framtida vattenplanerna kan därför behöva omprövas.

▼ Today, the great importance and benefits of renewable energies as a source of endless energy is obvious for all. Wind is recognized as one of the most stable and safest type of energy, due to ease of access as well as applying modern technical and scientific methods in order to its extraction. In this regard, much effort has been done in the developed societies to obtain knowledge besides getting access to new techniques in the exploitation of this unlimited wealth. Apart from the new aspects of the proposed research in wind area, the extraction operation requires specialists to advanced techniques and scientific research. The development of societies and their increasing necessity to energy resources have increased the importance of safe and clean renewable energy. This study investigates a technique to specify the power performance of the wind turbine directly from measured data which fluctuate with high frequency. This project is a review of a dynamical method for the specification of wind turbines' power curves. Considering the power output of a wind turbine in this study, the basic concept is to divide its dynamics into two components; a deterministic(relaxation) and a stochastic(noise) functions which are equivalent to the wind turbines' real behavior itself and the exterior wind turbulence. It specifically presents a procedure to estimate the reaction of the wind turbine as a machine to the wind speed dynamically. In this method, reconstruction of the coefficients from the measured data and extraction of the specification of the power output have been done. The main focus of this technique is on differential equations which are recognized as Langevin equations. As the consequence, it is shown; with this method we will be able to percept the conversion dynamics of wind turbines and get the power curves' results with high precision. The results demonstrate that power performance's specification is accurately reconstructed from the measured data by the quick estimation of the coefficients from data. Furthermore, the high accuracy and fast estimation of the power curves would be considered as preferences in this method.

▼ This master thesis is an investigation of environmental sustainability of photovoltaic (PV) modules. The purpose is to examine how purchasers of PV systems could put requirements on the modules so that their life-cycle carbon dioxide emissions reduces in the most effective way. The purpose is also to survey environmental third-party certifications for solar modules. Only mono- and multicrystalline silicon modules are considered. In the first part of the thesis, the carbon dioxide emissions from the manufacturing and transportation of different modules are calculated. Furthermore, the solar electricity production is simulated in the software PV syst. Modules with different peak power capacity, origins and manufactured with different techniques are compared. In part two, recycling techniques and regulations for management of end-of-life-modules are investigated. The number of end-of-life modules based on Solkompaniet Sverige AB´s historical installations are estimated and out of these, their potential economic value, based on two different recycling scenarios, is calculated. According to the results, monocrystalline modules cause higher emissions than equivalent multi-crystalline from the same manufacturer. Modules with the same peak power and silicon but with different origins and silicon manufactured with different technologies, produce about the same amount of electricity, but show a large variation in carbon dioxide emissions, mainly due the electricity consumption and the characteristics of the electrical mix used in the manufacturing process. The modules’ operating time in addition to pre requisite conditions for mounting are crucial for thee missions per produced kWh electricity, contrary the transports have very little effect on the total emissions. Carbon dioxide emissions could be reduced through re-usage of elements from recycled end-of lifemodules, particularly aluminum and silicon, but economic factors hinder this today, mainly due to too few end-of-life modules. Silveris the most expensive element in a module. The value of end-of-lifemodules will decrease by decreasing silver content, but overall increase due to increased waste volumes. The future economic value of end-of-life modules is hard to estimate, but could be crucial for the possibility to take advantage of the environmental benefit from treatment of end-of-life modules. In order to reduce carbon dioxide emissions from solar modules, requirements should be directed towards the module manufacturing process. This thesis emphasizes pre requisites expected to give lower emissions, hence modules that are more likely to cause lower environmental impact than others. To be able to develop specific requirements, more transparent and reliable energy consumption data is necessary. It exists very few, and no Swedish environmental certifications specifically designed for solar modules. The ranking list Solar Scorecard is not a certification but seems to be the most used in order to demonstrate manufacturers' environmental performances.

▼ This Thesis carries out a high level analysis of the financial feasibility of building integrated small scale renewable energy systems. A number of alternative system configurations have been established that include a mixture of grid connected wind turbines and solar photovoltaic (PV) applications to provide electricity to meet the demand of the base load demand of the building, with any occurrence of excess production sold back to the grid. A methodology to account for an analysis of their feasibility has been developed. The methodology is based on a well-known clean energy system analysis tool, namely RETScreen. The local climate data has been extrapolated and calculations carried out using the RETScreen database and software. From this, the maximum initial financial investment of the systems has been estimated, based on a given financial hurdle rate (i.e. the annual financial interest return on initial investment) and the savings and income generated from reduced grid electricity consumption and selling electricity back to the grid. The methodology is applied to an academic building located in the city of Visby on the Swedish island of Gotland, with a hurdle rate set to 7%. Electricity generation scenarios include 4 systems with 3.6 - 15.2 kW of wind, and 21.5 kW of PV located on a flat roof of a building containing office space, lecture rooms and a large student break area. Of the considered systems, it was concluded that the most feasible system was the system with a mixture of 15.2 kW of installed wind capacity and 21.5 kW of installed solar PV capacity. In addition, the results suggested that even with the grant system in place in Sweden for solar PV systems, the solar PV part of the systems would likely not be feasible. Therefore it was suggested that future work in this area should involve an investigation of a purely wind power system be carried out, as well as to investigate the hourly demand of the building and the hourly potential supply of the renewable energy system. The building permit process, installation and energy resources and requirements and installation should also be researched further, including taking actual energy consumption readings from the building and installing climate measuring instruments in the proposed positions on the roof in order to achieve more accurate input data.

▼ Modern energy systems face several challenges because of increased attempts by govern- ments and general public to push towards a sustainable future. Policy makers have been trying hard to construct policy frameworks that push the evolution of the energy system towards low carbon technologies. These policies are designed taking insights from com- puter models of the energy systems and their operation. Hence, modeling and analysis is important for understanding the impacts of certain policies on the energy system and comparing those impacts with the desired evolutionary path that the system must take in order to fulfill governmental targets in the context of sustainability. Since energy systems are complex with several inter connected sub systems and components, many models are required to simulate them in entirety. The multiplicity of models further increases when several distinct problems in the energy domain are desired to be modeled. This study investigates on creating a generic energy system modeling framework that will lay down a foundation and basis for several modeling problems in energy systems research. It also provides a common language for communication between modelers, therefore, easing the modeling process. This framework is realized by studying example problems which re- semble the problems that will be modeled in the future using this framework. Research questions are formulated and a literature survey is performed to create a knowledge base representing the modeling techniques used to models these problems and energy systems in general. Abstractions are drawn from all these exemplary studies and converted to con- crete concepts which can be represented as a piece of software. The conceptual framework uses an ontological approach to convert these abstractions into concretized software ele- ments. An agent based modeling approach is proposed as the primary modeling paradigm for the framework. The suitability of the ontological approach and agent based modeling is demonstrated and tested through the application of the framework for a case study. The case study is demonstrative, hence it is hypothetically formulated with assumed data values. In the case study, a hydrogen supply chain in a hypothetical energy system is mod- eled. The case study demonstrates energy system evolution, emergent effects of energy systems, features, strengths and weaknesses of the framework and agent based modeling as well. The conceptual framework developed in this thesis provides a preliminary step towards the standardization of the modeling process. Advisors/Committee Members: Boulouchos, Konstantinos, Georges, Gil.
