Résumé :

In Europe, 70% of citizens live in urban areas and consume around 75% of the primary energy supply. In order to reduce the impact of energy consumption and improve the competitiveness of local energy systems, Energy Communities may help to address the challenges of urban sustainability and energy security through local energy production and self-consumption. Solar, biomass and wind are the main sources of renewable energy that are generally used in cities. However, not all the sources available in urban environment are usable, due to the limited availability, or other technical or non-technical limits and constraints. In order to promote renewable energy technologies in buildings it is necessary to consider architectural, cultural, energy, technical and economic feasibility. This work defines a methodology for the optimal design of grid connected PV-battery systems in urban environments. The model was applied to two districts located in the city of Turin with the aim of evaluating the technical feasibility of combining multiple residential users at city level. The purpose of this work is to promote self-consumption and self-sufficiency from the network, using the integration of solar energy with PV-battery systems, and to reduce electrical losses in favor of both the single user and the distribution system. Results show that different values of self-sufficiency and self-consumption can be reached depending on the shape and dimension of each building. It was shown that it is possible to satisfy the current requirements to become an Energy Community in an urban environment with good levels of self-sufficiency.

Résumé :

The aim of the study is to analyze the level of energy self-sufficiency at the regional and local level. At the level of voivodships, the production of electricity, its relation to the energy consumed, the volume and dynamics of changes in the production of renewable energy in 2010-2016 and its share in total production are presented. Autonomous energy regions have been characterized as structures allowing to strive for energy self-sufficiency. The tests and analyzes used a comparative method and a breakdown of individual categories according to the analyzed values. As a result of the conducted analyzes, it was found that an important role in achieving energy self-sufficiency will be performed by micro and small installations based on local resources.

Résumé :

The war between Russia and Ukraine has started to have its biggest effects on the most used products by people around the world. The rise in energy prices has been the main headline of this war. In addition to the conventional regional and global security threats due to Russian aggression against Ukraine, the world is facing the unconventional threat of energy security. The energy produced in Russia is used as the main supplier for the economies of many bordering or non-bordering states, turning this product into a lever used by Russia to fuel its war and into a source of conflict among European allies and beyond. In this context, Albania cannot be immune to the skyrocketing energy prices. On the other hand, seeing Albania’s favorable situation in diversifying the necessary energy for the daily activities of families and businesses in our country, the government has undertaken the initiative to turn Albania into a net energy exporter until 2030. This means that Albania will no longer be so energy-dependent on fluctuations in prices on global stock exchanges, or dependent on the use of temporary regional initiatives such as “Open Balkans” to secure supply from other countries in the region but will become a country that achieves energy self-sufficiency in the coming decade. This work aims to highlight the threat to national security from the energy crisis and to use quantitative and qualitative data to understand whether this initiative is achievable in the years to come. Keywords: energy security, sustainable development, green renewable energy, Western Balkans.

Résumé :

Due to increased grid problems caused by renewable energy systems being used to realize zero energy buildings and communities, the importance of energy sharing and self-sufficiency of renewable energy also increased. In this study, the energy performance of an energy-sharing community was investigated to improve its energy efficiency and renewable energy self-sufficiency. For a case study, a smart village was selected via detailed simulation. In this study, the thermal energy for cooling, heating, and domestic hot water was produced by ground source heat pumps, which were integrated with thermal energy storage (TES) with solar energy systems. We observed that the ST system integrated with TES showed higher self-sufficiency with grid interaction than the PV and PVT systems. This was due to the heat pump system being connected to thermal energy storage, which was operated as an energy storage system. Consequently, we also found that the ST system had a lower operating energy, CO2 emissions, and operating costs compared with the PV and PVT systems.

Résumé :

Amid the ongoing climate crisis, the international community is enacting policies to promote low-carbon energy-sharing communities. The primary objective of such communities is to enhance community-level energy self-sufficiency. Accurate energy self-sufficiency assessments are paramount in planning energy-efficient architectural designs, urban landscapes, and communal environments. In this study, the energy self-sufficiency rate of an energy-sharing community was estimated at the design stage and compared with the actual energy self-sufficiency rate calculated based on data collected over the following year (April 2022 to March 2023). The outcomes reveal that the estimated energy self-sufficiency rate is 171%, whereas the realized rate is 133%, underscoring the disparity between the projections and outcomes. An analysis of the seasonal variations in these discrepancies elucidated a correlation between the differences in the insolation levels between standard typical meteorological year (TMY) data that are conventionally used for energy generation projections and the actual meteorological conditions. Moreover, a notable incongruity surface exists between the monthly average electricity consumption of a standard four-person household, as stipulated by the Korean Electric Power Corporation (KEPCO) at 273 kWh, and the empirical power consumption at 430 kWh, resulting in a variance of approximately 157 kWh. This study illuminates the complex relationship between variables affecting energy self-sufficiency in energy-sharing communities. It serves as a crucial step towards informed decision making and precision in sustainable urban energy solutions.

Résumé :

Energy has become an important issue for governments, communities and individuals, as concerns about energy prices, security of supply and climate change increase. Community scale low carbon energy systems could play an important role in future energy systems, but until recently UK government policy focussed on centralised energy systems. A number of rural communities elsewhere in Europe have made transformational whole settlement transitions from fossil fuel dependent towards renewable powered energy systems; however, the number of these in the UK is limited. Using a case study approach of European and UK cases, this research examines: reasons why rural communities embark on journeys towards whole place energy self-sufficiency; what capacities are present and contributions of these on outcomes achieved; whether there are similarities or differences between Europe and the UK and whether these are generalisable. European cases are examined using secondary and UK cases mainly primary data sources. Cases had varying rationales for embarking on whole settlement approaches to energy self-sufficiency. Whilst these don’t appear to determine the degree of energy self-sufficiency achieved, a whole settlement approach was considered important. No cases achieved energy self-sufficiency, but most made significant progress towards this and the idea did function as a boundary object. A number of capacities were present across all the cases such as public funding for energy system delivery, some capacities were present in the majority of cases and there were differences in capacities between the European and UK cases including leadership by local government. If the UK is serious about whole place energy self-sufficiency there needs to be; a commitment to public funding and resolving whether local authorities at their current scale and resourcing can provide leadership, or if alternative forms of local governance need to be found.

Résumé :

The consequences of over-reliance on fossil fuels for energy supply, namely climate change and security of supply, are pushing for the use of local, renewable energy sources which are usually variable in nature, prompting the need for energy storage. Today, there is a trend towards distributed energy storage, justified by the distributed nature of renewable energy sources and the important share of energy consumption in buildings. Important information on such small scale energy storage installations, however, is still missing and the results of the existing literature vary widely. To account for these research gaps, a thorough characterisation of energy storage technologies is performed, together with the dimensioning and optimisation of such installations in buildings, as well as some aspects of their impact on the grid.It is found that storage is still far from grid parity and expensive when compared to other solutions, although necessary for a high share of renewables. Also, energy storage is subject to important economies of scale and technical limitations that counter the reasoning for a distributed approach. There is an important lack of practical information on several energy storage technologies, and many studies on distributed storage use downsized values from large-scale installations that do not correctly depict smaller installations, leading to biased results. Nevertheless, today, lithium-ion batteries seem to be the most appropriate electrical energy storage technology for buildings, being well adapted to short term storage. On the other hand, a very high share of renewables will push for long term storage, itself a challenge given the high cost brought by a low utilisation factor. A high share of distributed generation also impacts the grid, a problem which most final consumers have no economic incentive to mitigate. Storage by itself, without a sound control strategy, does not help as it tends to increase the load variability while the peak load remains the same. Specific control algorithms could change that but incentives must be present, namely through the adaptation of current grid tariffs that do not correctly allocate existing costs. These findings are essential in the future planning of energy systems as well as in energy policy.

Résumé :

A growing world population has resulted in an increasing number of people being homeless or living in inadequate housing. In addition, the threatening climate crisis and the world’s limited resources calls for a more sustainable way of living. The organization Stockholm Tiny House Expo aims to contribute a solution to these issues: an artificial island with several tiny houses, able to adapt to rising sea levels, having net-zero-waste and completely self-sufficient regarding energy. This island will symbolize the sustainable development goals and will be an attraction for tourists, as well as create several job opportunities. In order to realize this vision, research needs to be conducted to find solutions to make this island become reality. Therefore, the aim of this project is to evaluate the economic and environmental feasibility of a high degree of self-sufficiency regarding energy, by locally producing heat and power, on an artificial island in Stockholm. Firstly, a literature review is conducted to find suitable technologies to supply the island with heat and power. Subsequently, the software tools IDA ICE and HOMER Pro are used to simulate the energy demand and supply of the island. Eight different scenarios, with different types of supply and demand, are created to investigate different possibilities of the island. The scenarios are evaluated using technical-, economic- and environmental key performance indicators. A scenario where the demand is reduced and heat and power are supplied only by resources on the island, is deemed most relevant based on Stockholm Tiny House Expo’s vision. A sensitivity analysis is therefore performed on this scenario. The results indicate technical and environmental feasibility; however, the economic evaluation showed that this scenario will be non-profitable. Although the scenario is non-profitable, if further measures are taken to create a pricing model to customers, it could be possible. In conclusion, the results of this research indicate that it is possible for Stockholm Tiny House Expo to be self-sufficient regarding heat and power solely utilizing renewable energy. The evaluation of the results, however, showed that it is not economically feasible. In addition, the national grid did not contribute to an impact on the surrounding environment, nor to a considerable amount of greenhouse gas emissions. Hence, grid connection is recommended for Stockholm Tiny House Expo.
En växande världspopulation har resulterat i att ett ökande antal människor är hemlösa eller bor i bristfälliga bostäder. Den hotande klimatkrisen och jordens begränsade tillgångar kräver dessutom en hållbarare livsstil. Organisationen Stockholm Tiny House Expo vill bidra med en lösning till dessa problem: en artificiell ö med flera småhus, som kan anpassa sig till stigande havsnivåer, har noll nettoavfall och är helt självförsörjande gällande energi. Denna ö kommer symbolisera FN:s hållbarhetsmål och vara en turistattraktion så väl som skapa ett flertal arbetsmöjligheter. För att förverkliga denna vision krävs forskning för att hitta lösningar och göra denna ö till verklighet. Därmed är syftet med detta projekt att undersöka den ekonomiska och miljömässiga genomförbarheten av en hög grad av självförsörjning av energi, genom att lokalt producera kraft och värme, på en artificiell ö i Stockholm. Först utförs en litteraturstudie för att hitta lämpliga teknologier för att försörja ön med kraft och värme. Därefter används programvarorna IDA ICE och HOMER Pro för att simulera energibehovet och energiförsörjningen för ön. Åtta olika scenarier, med olika typer av försörjning och behov, konstrueras för att undersöka olika möjligheter för ön. Scenarierna utvärderas med hjälp av tekniska-, ekonomiska- och miljömässiga nyckeltal (key performance indicators). Ett scenario där behovet är reducerat samt att kraft och värme endast försörjs av resurser på ön, bedöms vara mest relevant baserat på Stockholm Tiny House Expos vision. En känslighetsanalys utförs därför på detta scenario. Resultaten tyder på att scenariot är tekniskt och miljömässigt genomförbart; dock visade den ekonomiska utvärderingen att det inte är lönsamt. Trots detta så skulle det kunna vara möjligt om vidare åtgärder tas för att skapa en prissättningsmodell mot kunderna. Sammanfattningsvis så tyder resultaten på att det är möjligt för Stockholm Tiny House Expo att vara självförsörjande gällande kraft och värme som endast utnyttjar förnybar energi. Utvärderingen av resultatet visade dock att det inte är ekonomiskt genomförbart. Det nationella kraftnätet bidrog dessutom inte till påverkan på den omgivande miljön och inte heller någon betydande mängd växthusgasutsläpp. Följaktligen rekommenderas nätanslutning för Stockholm Tiny House Expo.

Résumé :

The task of this master thesis is to evaluate the potential and economic feasibility of a solar photovoltaic project at the Castle Château de la Chaize, situated near Lyon in France. The domain of the Château de la Chaize aims to be more ecologically responsible, by producing organic wine, using geothermal energy and producing its own electricity, using solar energy. The solar system would hence be used to produce the electricity that the castle and the vineyard would use. Since the whole domain is changing in order to be more sustainable, the energy consumption is still unclear. Three consumption scenarios are thus studied to model: the current situation (108 MWh), the change in energy needs due to the renewal of the wine making process (568 MWh), and finally the additional energy demand due to the construction of a spa on the domain lands (1056 MWh). The project site is also situated in the domain, near the Castle. The meteorological data and the shading scene are gathered from databases and site visits. Since the site is oriented towards the North-West and the South and East sides are blocked by a forest, significant shading losses are expected. In order to maximize the potential of the PV system, the use of Li-Ion batteries, to increases the self-generated part of the consumed electricity, is also considered. Simulations for the system production and the matching of the consumption and production is lead using the PVsyst software. Standard modules and inverters are used to run the simulation. The different configurations (energy consumption, size of the PV system, battery,...) are compared using the self-generation rate (part of the energy that is consumed that comes from the PV system) and financial criteria such as the Internal return rate or the profit at year 20. The results show that using a solar system to provide electricity for the current scenario would not be financially viable. For the renovation scenario, the best system design is the southward oriented fixed tilted plane at 350 kWp. It generates a profit of 71 k€ and has a self-generation ratio of 31.5 %. For the spa scenario, the 350 kWp south-oriented system is also the most interesting, with a self-generation rate of 29.8 % and IRR of 9.33 %. The financial analysis of the systems with batteries shows that the investment costs of the storage system are too high, and its lifetime is too short to be profitable. It would be interesting to see the evolution of the energy storage market, that is expected to develop, to see the economic interest of installing storage systems.
Uppgiften för detta examensarbete är att utvärdera potentialen och den ekonomiska genomförbarheten för ett solcellsfotovoltaikprojekt vid slottet Château de la Chaize, beläget nära Lyon i Frankrike. Domänen för Château de la Chaize syftar till att vara mer ekologiskt ansvarig, genom att producera ekologiskt vin, använda geotermisk energi och producera sin egen elektricitet med solenergi. Därför skulle solsystemet användas för att producera den elektricitet som slottet och vingården skulle använda. Eftersom hela området utvecklas för att bli mer hållbar är energiförbrukningen fortfarande oklar. Tre konsumtionsscenarier studeras sålunda för att modellera: den aktuella situationen (108 MWh), förändringen i energibehov på grund av förnyelsen av vinframställningsprocessen (568 MWh) och slutligen den extra energibehovet på grund av ett nytt spa på domänen landar (1056 MWh). Projektplatsen ligger också i domänen, nära slottet. Meteorologiska data och skuggningsscenen samlas in från databaser och webbplatsbesök. Eftersom platsen är inriktad mot nordväst, och södra och östra sidan blockeras av en skog, förväntas betydande skuggningsförluster. För att maximera PV-systemets potential övervägs också användning av Li-Ion-batterier för att öka den självgenererade delen av den förbrukade elen. Simuleringar för systemproduktion och matchning av konsumtion och produktion är bly med hjälp av PVsyst-programvaran. Standardmoduler och inverterare används för att köra simuleringen. De olika konfigurationerna (energiförbrukning, storleken på PV-systemet, batteriet, ...) jämförs med hjälp av självproduktionshastigheten (en del av energin som förbrukas som kommer från PV-systemet) och ekonomiska kriterier som intern avkastning eller vinsten vid år 20. Resultaten visar att användning av ett solsystem för att tillhandahålla el till det aktuella scenariot inte skulle vara ekonomiskt hållbart. För renoveringsscenariot är den bästa systemdesignen det söderutorienterade fasta lutningsplanet med 350 kWp. Det ger en vinst på 71 k € och har en egenproduktionsgrad på 31,5 %. För spa-scenariot är det sydorienterade systemet med 350 kWp också det mest intressanta, med en egenproduktionshastighet på 29,8 % och IRR på 9,33 %. Den ekonomiska analysen av systemen med batterier visar att investeringskostnaderna för lagringssystemet är för höga och att dess livslängd är för kort för att vara lönsam. Det skulle vara intressant att se utvecklingen av energilagringsmarknaden, som förväntas utvecklas, att se det ekonomiska intresset av att installera lagringssystem.

Résumé :

Este trabalho apresenta os estudos técnicos para implantação de um sistema de geração de energia que atenda a demanda dos circuitos eletroeletrônicos de um queimador de biogás, tornando-o autossuficiente energeticamente e viabilizando sua instalação em locais distantes e não atendidos pelo sistema convencional de distribuição de energia. O projeto do sistema de geração de energia tem como base a associação das tecnologias fotovoltaica e termoelétrica direta, tipo efeito Seebeck. O queimador de biogás descrito neste projeto é instalado em miniestações de tratamento de efluentes com produção de biogás, onde o aproveitamento energético da forma tradicional é inviável em função da baixa e inconstante vazão de biogás. O queimador de biogás possui um circuito eletrônico de controle que determina o tempo de combustão do biogás, onde, através de um microcontrolador, recebe informações do circuito eletrônico de controle e registra o volume de biogás queimado, objetivando a obtenção dos créditos de carbono. O queimador de biogás tem como objetivo somente o saneamento, provocando a queima do gás metano (CH4) presente no biogás e permitindo a busca por créditos de carbono, contribuindo para a diminuição dos efeitos provocados pelos gases do efeito estufa (GEE). Durante os estudos, foi constatado que a energia gerada pelo painel fotovoltaico é suficiente para atender a demanda de energia do circuito eletroeletrônico do queimador de biogás, enquanto que o sistema termoelétrico direto obteve resultados desprezíveis. Constatou-se também que parte do circuito do controlador de carga, utilizado nesse estudo, pode futuramente ser inserida no firmware do microcontrolador já existente no projeto, reduzindo assim significativamente os componentes do circuito.
This paper presents the technical studies for the implementation of a system of power generation to meet the energy demand of biogas burner electronics circuits, making it self-sufficient energy and enabling installation in remote locations not served by the conventional system of energy distribution. The design of the power generation system is based on the combination of photovoltaic technologies and thermoelectric direct like Seebeck Effect. The biogas burner described in this project is installed in mini-stations for treatment and biogas production, where energy reuse in the traditional way is not feasible due to the low and variable flow of biogas. The biogas burner has an electronic control circuit which determines the time of combustion of biogas, which, through a microcontroller receives information from the electronic control circuit and registers the volume of biogas flared aiming to get carbon credits. The biogas burner, aims only sanitation, causing burning methane gas (CH4) present in biogas and allowing the search for carbon credits, helping to reduce the effects caused by greenhouse gases (GHG). During the studies, it was found that the energy generated by the photovoltaic panel is enough to attend the energy demand of the electronics circuit of biogas burner, while the direct thermoelectric system obtained a negligible result. It was found that part of the charge controller, used in this study, in the future can be inserted into the firmware of the microcontroller existing of the in the project, reducing therefore the circuit components significantly.

Résumé :

Energy storage is of increasing interest as an enabler of incorporating renewable intermittent power in the power systems globally. There are several technologies for energy storage, and this thesis focuses on battery energy storage systems (BESS). Previous research has shown that it is difficult to install BESS with a payback time within the battery lifetime, making it a challenge to realise profitable investments. The complexity of developing an optimal control of the battery is also documented in research as another challenge. Optimal sizing of the BESS could be a solution to the challenge of reaching profitability. The thesis is identifying and analysing some important technical and energy-related parameters affecting the performance of BESS installations. Identification and analysis of parameters affecting the performance will help build insight into the optimization of BESS and help enable the development of more efficient sizing and operation. By developing an algorithm simulating the BESS when controlled using two different strategies, this thesis additionally contributes to the research by displaying the complexity of battery control, which is realised by the energy management system (EMS). Thereby the thesis is adding to the research base for the future development of smarter and more optimal EMS. The main research methodologies used in the thesis was a literature study and a case study. The results suggested that the energy management strategy used in the battery control was gravely affecting the performance in terms of economic profitability, self-sufficiency and environmental impact. It was also implied that it is difficult to develop an efficient battery control to reach the full potential of the storage system. The main conclusions in this paper are that the most important parameters to consider when implementing a battery storage in a residential multifamily building are battery technology, battery capacity, building load, renewable energy generation, energy management strategy as well as the electricity prices and investment cost. The energy management strategy most favourable for the case building studied was found to be a combination of optimizing the self-sufficiency and performing peak shaving. It would also be preferable to further develop the battery control to also take electricity prices and balance services into consideration. For this, AI and machine learning could be integrated in the control of the system. According to the case study results, the lithium ion battery technology had better potential for reaching economic profitability while the nickel metal hydride technology showed better potential in terms of environmental performance. The choice of battery technology and energy management strategy should however be adjusted to the customer specific demands and prerequisites.

Résumé :

The issue of energy self-sufficiency is currently crucial. The concept of energy selfsufficiency is closely related to the concept of energy security; yet, there are many definitions for the term energy security. The essence of all of them is for a country to secure enough energy resources to cover its needs. If a country can secure these resources on its own without depending on imports from other countries, one refers to energy self-sufficiency. Energy self-sufficiency can be achieved in a number of ways such as reducing energy demand, improving fuel efficiency, securing physical infrastructure networks, increasing storage capacity, or increasing the use of renewable energy sources. Fundamental forms of energy self-sufficiency are external self-sufficiency, internal selfsufficiency, and energy consumption; overall, energy self-sufficiency consists of four components: availability; affordability; energy and economic efficiency; and environmental stewardship. Low energy self-sufficiency has a significant economic and social impact, which is reflected in a country's balance of payments and employment, it can lead to economic crises and price instability. Lack of access to reliable and affordable energy can result in food insecurity; health problems; limited access to education, social and economic development. The linkages between energy, food self-sufficiency, and self-sufficiency of water resources are considered in terms of the so-called WEF Nexus (Water-Energy-Food Nexus) that focuses on the interconnectedness of water, energy and food systems to promote sustainable development and address global climate change. Based on the application of scientific methods in relation to the investigation of energy self-sufficiency (the �E� Matrix in the framework of the WEF Nexus) on the background of quantitative & qualitative sustainable development and CSR trends, the main aim of our paper is to assess energy self-sufficiency in the context of the WEF nexus as well as in the light of the United Nations 2030 Agenda Sustainable Development Goals (SDGs) in order to formulate opportunities arising from the European Union Recovery and Resilience Plans. When documenting quantitative & qualitative sustainable development trends in the context of the WEF Nexus, our paper addressed the United Nations 2030 Agenda (alias �SDG diplomacy�) as well as the NextGenerationEU Agenda (alias �Green Deal diplomacy�).

Résumé :

To increase our food security in Västerbotten we will need to become more self-sufficient of both energy, feed and nutrients that are now imported to the region. Biogas production from different waste streams is one solution to this. Biogas is produced using biowaste or sewage sludge as substrate in the major cities Umeå and Skellefteå. Biogas systems offer a range of benefits to society. Biogas production is currently prized for its climate benefits when replacing fossil fuels for the production of heat, electricity and vehicle gas, but at Bothnia Nutrient Recycling we have studied how to use the digestate, i.e. the residual product of production, as fertilizer in agriculture. We have been working to improve profitability for biogas producers and develop sustainable products from recycled nutrients, like phosphorus and nitrogen. Improving the uses for digestate increases self-sufficiency in agriculture and contributes to a circular economy. We conducted three agricultural demonstration experiments in collaboration with agricultural high schools in Finland and Sweden to introduce digestate and digestate products to the future farmers in the regions. We found that it may be possible to replace cattle slurry with compost when growing maize despite the low levels of nitrogen, N, available to plants in the compost. In barley, NPK fertilizers gave the highest yield. Digestate from HEMAB and sludge biochar supplemented with recycled ammonium sulphate gave a smaller yield but higher than unfertilized crop. Digestate from a dry digestion biogas plant in Härnösand was better suited to barley than to grass because in an experiment on grass ley the viscous fertilizer did not penetrate the grass and did not increase the growth of the grass. Fertilizer effects on crop quality were small. There was no increased uptake of heavy metals in barley after fertilization with digestate or digestate products compared to NPK fertilization. These demonstration experiments show that more thorough scientific experimentation is needed as a foundation for recommendations to farmers. The amounts of nitrogen and phosphorous in digestate from Västerbotten that could become used as fertilizer were modelled. It showed that if sewage sludge digestate is used to make sludge biochar and ammonium sulphate and the other available digestates are used directly in agriculture, the entire phosphorous demand but only a small part of the nitrogen demand in the county, could be covered. Thus, to achieve a true circular food production, development and increase of both the waste handling sector and agriculture is needed.
