This book was released on 2019-11-18 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are numerous problems in the world that need to be dealt with in order to achieve sustainable development. The energy system has significant negative impacts on many of these problems, and there is a need for a transition towards more sustainable energy. Sweden has already started this transition and is using large amounts of renewable energy. However, within the transport sector and the manufacturing sector in particular, large amounts of fossil fuels are still used. Biogas is one alternative that can help solve several sustainability problems and that could be part of a future more sustainable energy system. However, it is not certain what biogas is most suitable to be used for. The aim of this thesis is to investigate how biogas should be used in a future more sustainable energy system, by answering three research questions: 1) In what ways can biogas be used in a more sustainable energy system? 2) How can we assess whether biogas is suitable in a specific context? and 3) What determines whether it is easy or difficult for a user to start using biogas? These questions are explored in a Swedish context using four appended articles, which are based on two collaborative projects using a combination of workshops, literature reviews and interviews. Biogas can be used for heat, electricity or fuel in the manufacturing or transport sector. In Sweden, heat and electricity are mainly of interest for smaller production scales, while production on larger scales will likely be dominated by upgrading mostly to CBG but also to LBG. CBG can be used for less energy-intensive purposes, such as cars or buses, while the growing interest in LBG in Sweden may open up new market segments for biogas which are more energy-intensive, such as heavy trucks or shipping, or in geographical locations that are further away from the site of production. Several sustainability assessment methods exist that can be used to evaluate whether biogas is suitable in a specific context, such as multi-criteria assessments or scenario analyses. These methods can include a number of different aspects that are relevant to biogas use, such as GHG emissions, safety issues, and the vitality of the surrounding region. In order to introduce biogas, six main factors were identified that can make this easier or more difficult: technical maturity, tank volume, distance between the producer and the user, scale of energy use, policies and costs, and strategies of individual organizations. Overall, the rise in LBG production creates new opportunities for biogas use in both geographical and usage areas that did not previously use biogas. There is no simple answer to what biogas should be used for in the future – rather, this depends on the circumstances. It is also possible that the usage areas that are most suitable now for biogas might not be the most suitable areas in the future, depending on developments within, for example, the electricity system and hydrogen. However, CBG and LBG are likely to dominate biogas production in Sweden until then.
Book Synopsis System studies of biogas production by : Emma Lindkvist
Download or read book System studies of biogas production written by Emma Lindkvist and published by Linköping University Electronic Press. This book was released on 2020-04-29 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biogas has the potential to be part of the transition towards a more sustainable energy system. Biogas is a renewable energy source and can play an important role in modern waste management systems. Biogas production can also help recirculate nutrients back to farmland. Besides all this, biogas is a locally produced energy source with the potential to increase global resource efficiency, since it can lead to more value and less waste, as well as decreased negative environmental effects. However, biogas production systems are complex, including different substrates, different applications for biogas and digestate, and different technology solutions for digestion, pre-treatment and for upgrading the raw gas. To increase the development of biogas production systems, knowledge sharing is a key factor. To increase this knowledge sharing, comprehensible analysis and comparisons of biogas production systems are necessary. Thus, studies are needed to verify the resource efficiency of biogas production systems from different perspectives. The aim of this thesis is to perform a systems analysis of biogas production systems and to explore how to analyse and compare biogas production systems. An additional aim is to study biogas production systems from a systems perspective, with a focus on environment, energy and economy. Studying biogas production systems from different system levels, as well as from different approaches, is beneficial because it results in deeper knowledge of biogas systems and greater opportunities to identify synergies. Systems studies of biogas are important, since biogas systems are often complex and integrated with other systems. In this thesis, biogas systems analyses are performed at different levels. In the widest system study, classifications of different biogas plants are analysed and classifications in different European countries are compared, with the prospect of paving the way for a new common classification for biogas plants in Europe. Today, classifications vary between countries, and hence comparisons of plants in different countries are difficult. In the narrowest system study, a new methodology for analysing energy demand at different biogas production plants has been developed. The aim was to develop a methodology that is applicable for all kinds of biogas plants with energy inputs. The methodology describes the process of analysing energy demand and allocating energy to sub-processes and unit processes. Further, an approach for assessing the resource efficiency of different treatment options for organic waste was designed. The approach includes environmental, economic and energy perspectives, and was applied to five different regions with several food manufacturing companies. A study of treatment options for organic waste from a single food company was also conducted. The results showed that biogas production is a resource-efficient way to treat waste from the food industry. The approach enables a wider analysis of biogas systems, and the results from the applications show the complexity of assessing resource efficiency. It is also shown that it is important to understand that the resource efficiency of a system is always in relation to the substituted system. In this thesis, three different approaches to analysing biogas production systems are presented: categorization, resource efficiency analysis and energy demand analysis. These approaches all contribute to the understanding of biogas systems and can help, in different ways, to increase knowledge about biogas systems in the world. If knowledge about different biogas systems can be easily disseminated, more of the unused potential of biogas production may be realized, and hence more fossil fuels can be replaced within the energy system. Biogas har potentialen att vara en del av övergången till ett mer hållbart energisystem. Biogas är en förnybar energikälla som kan spela en viktig roll i moderna avfallshanteringssystem. Produktion av biogas kan även hjälpa till att återcirkulera näringsämnen tillbaka till jordbruksmark. Förutom allt detta är biogas en lokalt producerad energikälla med potential att öka resurseffektiviteten i världen, eftersom det kan leda till ökat värde och mindre avfall samt minskade negativa miljöeffekter. Dock är biogasproduktionssystem komplexa, inklusive exempelvis olika substrat, användning för biogasen och rötresterna, olika tekniska lösningar för rötresterna såväl som förbehandling av substrat och uppgradering av rågas. För att öka utvecklingen av biogasproduktionssystem är kunskapsdelning en nyckelfaktor. För att öka kunskapsdelningen är tydliga analyser och jämförelser av biogasproduktionssystem nödvändiga. Därför behövs studier för att verifiera resurseffektiviteten för biogasproduktionssystem från olika perspektiv. Syftet med denna avhandling är att utföra systemanalyser av biogasproduktionssystem och att undersöka hur man analyserar och jämför biogasproduktionssystem. Vidare är syftet också att studera biogasproduktionssystem ur ett systemperspektiv med fokus på miljö, energi och ekonomi. Det är fördelaktigt att studera biogasproduktionssystem på olika systemnivåer och utifrån olika tillvägagångssätt, eftersom kunskapen om biogassystem fördjupas och möjligheterna att hitta synergier ökar. Systemstudier av biogas är viktigt eftersom biogassystem ofta är komplexa och integrerade i andra system. I denna avhandling utförs analyser på olika nivåer av biogassystemen. På den högsta systemnivån analyseras klassificeringar av olika biogasanläggningar. Klassificeringar i olika europeiska länder jämförs, med förhoppningen att bana väg mot en ny, gemensam klassificering för biogasanläggningar i Europa. Idag varierar klassificeringarna mellan länder och därför är jämförelser av anläggningar mellan länder svåra. På den lägsta systemnivån utvecklades en ny metod för analys av energibehov vid olika biogasproduktionsanläggningar. Syftet var att utveckla en metod för alla typer av biogasanläggningar. Metodiken beskriver processen för att analysera energibehov och fördela energin till delprocesser och enhetsprocesser. Vidare utformades en metod för att bedöma resurseffektiviteten hos olika behandlingsalternativ för organiskt avfall. Metoden inkluderar miljö, ekonomi och energi och tillämpades i fem olika regioner med flera livsmedelsindustriföretag. En studie av behandlingsalternativ för organiskt avfall från ett enda livsmedelsföretag genomfördes också. Resultaten visade att biogasproduktion är ett resurseffektivt sätt att behandla avfall från livsmedelsindustrin. Metoden möjliggör en bredare analys av biogassystem och resultaten från tillämpningarna visar komplexiteten i att utvärdera resurseffektiviteten. Det visas också att det är viktigt att förstå att ett systems resurseffektivitet alltid är i förhållande till det substituerade systemet. I denna avhandling presenteras tre olika metoder för analys av biogasproduktionssystem: kategorisering, resurseffektivitetsanalys och energibehovsanalys. Dessa tillvägagångssätt bidrar alla till att förstå biogassystem och kan på olika sätt bidra till att öka kunskapen för biogassystem i världen. Med bra system för att sprida kunskap om olika biogassystem kan mer av den outnyttjade potentialen för biogasproduktion realiseras och därmed kan fler fossila bränslen i energisystemet ersättas, samtidigt som de övriga fördelarna med biogas också kommer samhället till nytta.
Download or read book Biogas written by Abd El-Fatah Abomohra and published by BoD – Books on Demand. This book was released on 2021-04-28 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anaerobic digestion (AD) is by far the most important technology for providing clean renewable energy to millions in rural areas of many developing countries. AD of biowastes produces both biomethane and anaerobic digestate as a byproduct that can be used further as a biofertilizer. Biowastes including sewage, food processing wastes, animal wastes, and lignocellulosic wastes typically produce biogas containing 55%–70% biomethane. In the context of energy consumption, more than 85% of the total energy consumed currently comes from non-renewable fossil resources. Biogas technology can provide sustainable, affordable, and eco-friendly energy through waste recycling. This book provides basic knowledge and recent research on biogas production, focusing on the enhancement of biomethane and production routes integrated with microalgae cultivation or agriculture.

This book was released on 2024-04-16 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biogas offers a sustainable alternative to fossil fuels, promoting circularity and local economic growth. It is, therefore, increasingly prioritised by decision-makers within Sweden and the EU. Despite its advantages, the Swedish market is perceived as underachieving in terms of scale and penetration. Biogas, a socio-technical system, has necessitated state and regional support for its establishment and expansion, given its competition with entrenched fossil fuels and its inherent material limitations. This thesis primarily seeks to explore how the interplay of political, societal, and market perspectives has influenced the biogas market. The research zeroes in on the Swedish biogas market, with a special focus on the impact of geographical regions on market shaping. Using in part a longitudinal case study revealed that historically, successful regions have relied heavily on translations of missions and visions for developing the biogas markets. These translations were found to build heavily on local concerns and local resources. The consequence of this meant that the global context of the climate problem was not always the focus of policy and strategies. The significance of local interpretation was further unveiled as a component of value creation, where value is closely tied to the material and social conditions of local geographies. Value creation for intricate systems like biogas, which are multifunctional and span various social domains, indicates that biogas and biofertilisers are entities that are both naturally and socially constructed, underlining the impossibility of separating the natural from the social. The socio-material properties were important for biogas market shaping, as shown by tracing both biogas and biofertilisers. The connections between methane and fossil gas were found to be positive and negative for the biogas market. The reliance on fossil gas has created conditions that allow the biogas market to expand. However, the narrative of fossil gas as a bridge has, at times, led to doubts about biogas, and there is a risk that instead of biogas greening fossil gas, fossil gas has a ‘browning’ effect on the biogas market. For biofertiliser, the socio-material was found to be in a phase of change. It was found that the biogas market has been built for the energy market, but increasingly, it is important to consider the role of biofertiliser in this market. What was previously considered to be a by-product and a problem for the producers, is increasingly seen as an asset. Similar to the findings of the connection between fossil gas and biomethane, this is a change in social framings more than a change in the material. The movement from waste to by-product to an asset can be an important view both empirically and theoretically to foreground that for an object to be understood as valuable or sustainable, work is needed. This highlighted that markets do not simply appear, and objects are not inherently valuable or sustainable. It is instead an interplay between the social, material, and technical, which (re)shapes products and their markets. Lastly, this thesis, through the lens of marketisation, traced the concerns of the bio-gas market. It found that the biogas market is still evolving often referred to as a hot market. The boundaries of the market, including what is considered an externality, are still being defined. While this doesn’t fully account for the slow growth, it does enable stakeholders to use this understanding to influence the market’s development. As the biogas market changes, along with other factors such as the role of fossil gas, the impact of material changes with liquified biogas, and the growth of the concentrated biofertiliser market, it’s evident that the narratives will shift. This thesis adds to the empirical literature on renewable energy by emphasising that regions that depend on creating value for their citizens by promoting a local narrative will need to adapt to reflect the new material realities. This will influence both how valuation processes are conducted and the use of missions and visions by both the public and private sectors. Biogas är ett hållbart alternativ till fossila bränslen och kan dessutom främja cirkularitet och lokal ekonomisk tillväxt. Därför har biogasen alltmer prioriterats av beslutsfattare i Sverige och EU. I Sverige anses dock biogasmarknaden vara underpresterande när det gäller storlek och räckvidd. Biogas är ett sociotekniskt system som har krävt omfattande stöd från stat och lokala regioner för att etableras på grund av konkurrensen från fossila bränslen men också till följd av dess materiella restriktioner. Det primära syftet med denna avhandling är att undersöka hur samspelet mellan olika politiska, samhälleliga och marknadsmässiga inramningar har format biogasmarknaden. Studien fokuserar på biogasmarknaden i Sverige, med särskild tonvikt på olika geografiska regioners roll. En longitudinell fallstudie har gjort det möjligt att observera vilken central roll tolkningar av uppdrag och visioner har spelat för att motivera lokala aktörer att framgångsrikt utveckla biogasmarknaderna i utvalda regioner. Lokala policy-tolkningar visade sig i hög grad bygga på lokala problem och resurser som finns tillhands. Detta innebar också att klimatproblemen i en global kontext inte alltid var i fokus. Den lokala policytolkningen visade sig vidare vara en del av värdeskapandet, där värdet kopplades nära den regionala materiella och sociala kontexten. Dessa värdeskapandeprocesser visade också tydligt att biogas och biogödsel är objekt som är både naturligt och socialt konstruerade. Analysen visade den bristande förmågan att skilja på det naturliga och det sociala i komplexa system som spänner över flera sociala sfärer. De socio-materiella egenskaperna hos biometan och biogödsel är viktiga för utformningen av biogasmarknaden. Ett tydligt exempel är den nära relationen mellan biometan och fossilgas som har visat sig ha både för- och nackdelar för biogasmarknadens utveckling. En fördel är att biometan genom att använda fossilgasinfrastruktur lätt kan expandera. Narrativet om fossilgas som en brygga till fossila-fria samhället kan ses som en nackdel eftersom det har lett till tvivel om biogasens roll. Det finns en uppenbar risk för att biogasen genom fossilgaskopplingen bara anses göra fossilgas mer accepterad. Att biogödselns ställning på biogasmarknaden håller på att förändras påverkar också biogasproduktionens förutsättningar. Det som tidigare betraktades som en biprodukt till produktionen av förnybar energi och ett problem för producenterna kan numera användas som en tillgång. I likhet med effekterna av samspelet mellan fossil gas och biometan rör detta sig om en förändring av de sociala ramarna snarare än en materiell förändring. Att detta förändrade synsätt varit av central betydelse är en observation som är viktig både ur en empirisk och teoretisk synvinkel. Det visar att det går att förändra uppfattningen om ett objekt. Om objektet ska förstås som värdefullt eller hållbart krävs emellertid omfattande insatser. Det rör sig om ett samspel mellan de sociala, materiella och tekniska aspekter som (om)formar produkter och marknader. Slutligen, användningen av begreppet ”marketisation” bidrog till att synliggöra biogasmarknadens problem. Analysen visar att biogasmarknaden fortfarande utvecklas och är vad som, brukar kallas en ”het marknad. Gränserna för marknaden, inklusive vad som betraktas som externa effekter, håller fortfarande på att definieras. Även om detta inte helt förklarar den långsamma tillväxten, gör det möjligt för intressenter att använda denna kunskap för att påverka utformningen av marknaden. När biogasmarknaden förändras, tillsammans med andra faktorer såsom rollen för fossilgas, effekten av materiella förändringar med flytande biogas, och expansionen av den koncentrerade biogödselmarknaden, är det tydligt att narrativen kommer att behöva förändras. Avhandlingen bidrar till den empiriska litteraturen om förnybar energi genom att visa hur regioner genom lokalt förankrade narrativ motiverat hur biogas-satsningarna, skapat värde för medborgarna. Dessa narrativ kommer att behöva anpassas för att återspegla de nya materiella verkligheterna.

Available in PDF, EPUB and Kindle. Book excerpt: This book sets the questions of energy and the environment in the North in the global context and further addresses historical developments, views on energy taxation and tariffs, and effects of EU energy policy. Climate change appears more frequently than ever on the top of global and national policy agendas. In the current situation traditional environmental concern and environmental policy may not suffice in the face of the global challenge as manifested by climate change and the depletion of fossil energy resources. But as new data comes to light, new energy policies and changes in economic structures are crucial for putting into action global climate policy. Crucial tasks in environmental policy are the sustainable utilisation of natural resources and the conservation of natural and human-made habitats. One of the areas of the world where this comes into play the most is in the Nordic countries. Northern societies are predominantly high tech, high consumption and high energy supply societies. And with the transition from older energy sources (wood for heating and stream water for power production) to newer ones (oil and nuclear energy) discussions on the environmental impact have led to public and corporate action. The Northern countries have been at the forefront in finding sustainable alternatives to solve conflicts arising from the rise in energy needs. However, these countries have taken different pathways with different policies in attempting to achieve this. As the needs and concerns from climate change arise, a Northern dimension, involving policies that contrast to European and global trends, emerges. Energy, Policy, and the Environment: Modeling Sustainable Development for the North explores that dimension.
Book Synopsis How do biogas solutions influence the sustainability of bio-based industrial systems? by : Linda Hagman
Download or read book How do biogas solutions influence the sustainability of bio-based industrial systems? written by Linda Hagman and published by Linköping University Electronic Press. This book was released on 2018-11-26 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biomass is a valuable and limited resource that should be used efficiently. The potential of replacing fossil-based products with bio-based ones produced in biobased industrial systems is huge. One important aim of increasing the share of biobased products is to improve the sustainability of systems for production and consumption. Therefore, it is important to evaluate what solutions are available to improve the sustainability performance of bio-based industrial systems, and if they also bring negative impacts. The thesis focuses on assessing the role of biogas solutions in developing sustainable bio-based systems. Such assessments are often quite narrow in their scope and focus on quantitative environmental or economic aspects. This thesis aims at also including feasibility related aspects involving the contextual conditions that are assessed more qualitatively. Biogas solutions are identified as a versatile approach to treat organic materials which are generated in large volumes in bio-based industrial systems. The results show that biogas solutions in bio-based industrial systems (i) improve circular flows of energy and nutrients, (ii) are especially viable alternatives when the quality of the by-product streams become poorer, and (iii) may improve the profitability of the bio-based industrial system. To perform better assessments of these systems, it seems valuable to broaden the set of indicators assessed and include feasibility-related indicators, preferably through the involvement of relevant stakeholders as they contribute with different perspectives and can identify aspects that influence the sustainability in different areas. Future studies could benefit from applying those broader assessments on more cases to build on a more generalisable knowledge base.

Book Synopsis Handbook of Bioenergy Economics and Policy by : Madhu Khanna
Download or read book Handbook of Bioenergy Economics and Policy written by Madhu Khanna and published by Springer Science & Business Media. This book was released on 2009-12-02 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concerns about energy security, uncertainty about oil prices, declining oil reserves, and global climate change are fueling a shift towards bioenergy as a renewable alternative to fossil fuels. Public policies and private investments around the globe are aiming to increase local capacity to produce biofuels. A key constraint to the expansion of biofuel production is the limited amount of land available to meet the needs for fuel, feed, and food in the coming decades. Large-scale biofuel production raises concerns about food versus fuel tradeoffs, about demands for natural resources such as water, and about potential impacts on environmental quality. The book is organized into five parts. The introductory part provides a context for the emerging economic and policy challenges related to bioenergy and the motivations for biofuels as an energy source. The second part of the handbook includes chapters that examine the implications of expanded production of first generation biofuels for the allocation of land between food and fuel and for food/feed prices and trade in biofuels as well as the potential for technology improvements to mitigate the food vs. fuel competition for land. Chapters in the third part examine the infrastructural and logistical challenges posed by large scale biofuel production and the factors that will influence the location of biorefineries and the mix of feedstocks they use. The fourth part includes chapters that examine the environmental implications of biofuels, their implications for the design of policies and the unintended environmental consequences of existing biofuel policies. The final part presents economic analysis of the market, social welfare, and distributional effects of biofuel policies.

Book Synopsis Multiple Imaginaries of the Fossil Fuel Free Future by : Amelia Mutter
Download or read book Multiple Imaginaries of the Fossil Fuel Free Future written by Amelia Mutter and published by Linköping University Electronic Press. This book was released on 2020-02-03 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: I kölvattnet av klimatkrisen har det blivit allt tydligare att det fossilbaserade transportsystemet måste genomgå en global omvandling. Många alternativ för förnyelsebara drivmedel har föreslagits, alla omgivna av föreställningar om hur dessa tekniker kommer att bidra till en bättre framtid. Dessa föreställningar påverkar utvecklingen eftersom implementeringen av varje alternativ teknik kräver uppbyggnad av mångfaldiga socio-tekniska ensembler som stöder dess användning. Som ett resultat av detta är det troligt att processen för att ersätta fossila bränslen med dessa förnybara alternativ kommer bli komplex. Avhandlingen betraktar uppkomsten av två av dessa föreställningar om förnybara bränslen och studerar visioner om biogas och el i ett svenskt sammanhang. Biogas har en lång historia som transportbränsle i Sverige där, även om den utgör en liten andel av den totala bränsleanvändningen, utgör den ändå grunden för många kommunala kollektivtrafiksystem. Elektriska fordon har blivit alltmer attraktiva när fler aktörer anammar en föreställning som ser en framtid där fordon är delade, autonoma och elektriska. Denna interaktion exemplifieras i kollektivtrafik i städer eftersom många kommuner börjar implementera elbussar i ett försök att öka energieffektiviteten och minska föroreningarna. Denna avhandling följer tre fallstudier där föreställningarna om biogas och elfordon samverkar: kollektivtrafik i städerna Linköping respektive Malmö samt en analys av det omfattande nationella policydokumentet Fossilfrihet på väg. Avhandlingen bidrar till en bredare förståelse för hur visioner kan påverka tröghet och förändring av transportalternativ inom den bredare omställningen till en fossilfri framtid. In the wake of the climate crisis, it has become increasingly evident that the fossil fuel-based transport system must undergo a global transformation. Numerous renewable fuel alternatives have been suggested, accompanied by imaginaries of how these technologies will contribute to a better future. These imaginaries have a wide-ranging impact because the implementation of each alternative technology will require the build-up of multifarious socio-technical ensembles that support their use. As a result, replacing fossil fuels with these renewable alternatives is likely to be a complex process. This dissertation considers the emergence of two such visions of renewable fuels studying imaginaries of biogas and electricity in the Swedish context. Biogas has a long history of use as a transport fuel in Sweden, where although it makes up a small percentage of total fuel use it also forms the basis of numerous municipal public transport systems. Meanwhile, electric vehicles have become increasingly attractive as more actors subscribe to an imaginary that sees the future of vehicles as shared, autonomous, and electric. This interaction is exemplified in urban public transportation as many municipalities begin to implement electric buses in an attempt to increase energy efficiency and reduce pollution. This thesis follows three case studies where the imaginaries of biogas and electric vehicles interact: urban public transport in the municipalities of Linköping and Malmö, and analysis of a comprehensive national policy document Fossil fuel freedom on the road. It contributes to a wider understanding of how visions can influence obduracy and change of transport alternatives within the wider transformation to a fossil fuel free future.

Book Synopsis Small-Scale Renewable Energy Systems by : Sven Ruin
Download or read book Small-Scale Renewable Energy Systems written by Sven Ruin and published by CRC Press. This book was released on 2019-10-16 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: A revolution is ongoing in the field of small-scale energy solutions, which can enable lower impact on the environment, more robust supply and self-determination. Solar power and other forms of renewable energy sources, which you can implement to generate your own electricity, are growing quickly. Electromobility is transforming the car industry and transportation systems and can also play a role in your energy system. Electricity can be used much more efficiently than before, for example by using LED light, variable speed motor drives and efficient home appliances. Smart controls are available, sometimes with free open source software. All this opens up tremendous opportunities for energy independence, which is the focus of this book. The book introduces the reader to a number of renewable energy sources, to different options for storing electricity and to smart use of electricity, particularly in the context of small isolated systems. This is important because many renewable energy sources are weather- and season-dependent and usually require storage and smart control, in order to obtain a system that is completely independent of the electricity grid. In the book, overall system design is explained, including how to combine different sources in a hybrid system. Different system sizes and architectures are also covered. A number of real cases are described, where homes, businesses and communities have achieved a high level of energy independence or are on their way to achieving it. This book will prove useful in university education in renewable energy at bachelor and master level, and also for companies and private individuals, who want to start or expand activities in the area of renewable energy.

In the context of energy consumption, more than 85% of the total energy consumed currently comes from non-renewable fossil resources. A wide variety of biowastes can be used as feedstocks for biogas production. Biogas technology can provide sustainable, affordable, and eco-friendly green energy along with useful byproducts. This book discusses the basics of biogas production and aims to address the needs of graduate and postgraduate students as well as other professionals through further evaluation of biogas production via case studies.

Download or read book Low Carbon Energy Technologies in Sustainable Energy Systems written by Grigorios L. Kyriakopoulos and published by Academic Press. This book was released on 2021-01-08 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Low Carbon Energy Technologies for Sustainable Energy Systems examines, investigates, and integrates current research aimed at operationalizing low carbon technologies within complex transitioning energy economies. Scholarly research has traditionally focused on the technical aspects of exploitation, R&D, operation, infrastructure, and decommissioning, while approaches which can realistically inform their reception and scale-up across real societies and real markets are piecemeal and isolated in separate literatures. Addressing both the technical foundations of each technology together with the sociotechnical ways in which they are spread in markets and societies, this work integrates the technoeconomic assessment of low carbon technologies with direct discussion on legislative and regulatory policies in energy markets. Chapters address issues, such as social acceptance, consumer awareness, environmental valuation systems, and the circular economy, as low carbon technologies expand into energy systems sustainability, sensitivity, and stability. This collective research work is relevant to both researchers and practitioners working in sustainable energy systems. The combination of these features makes it a timely book that is useful and attractive to university students, researchers, academia, and public or private energy policy makers. Combines socio-cultural perspectives, environmental sustainability, and economic feasibility in the analysis of low carbon energy technologies Assesses regulatory governance impacting the environmental protection and the social cohesion of environmentally-directed energy markets Reviews the carbon trade exchange, attributing economic value to carbon and enabling its trading perspectives by people, companies or countries invested in low carbon technologies
