    Sammanfattning : Energisystemet omstruktureras. Nya energikällor tillkommer och andra fasas ut samtidigt som efterfrågan på energi kvarstår ur ett globalt perspektiv. LÄS MER

  3. 17. Development and characterization of functional composite materials for advanced energy conversion technologies

    Författare :Liangdong Fan; Bin Zhu; Torsten Fransson; Mahmut D. MAT; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low temperature ceramic fuel cell; Ceria-carbonate composite; Electrolysis; Transition metal oxide; Symmetrical fuel cells; All-nanocomposite fuel cell; Electrolyte-free fuel cell; Solar cell; ion conductor and semiconductor; SRA - Energy; SRA - Energi;

    Sammanfattning : The solid oxide fuel cell (SOFC) is a potential high efficient electrochemical device for vehicles, auxiliary power units and large-scale stationary power plants combined heat and power application. The main challenges of this technology for market acceptance are associated with cost and lifetime due to the high temperature (700-1000 oC) operation and complex cell structure, i. LÄS MER

  4. 18. Integrated regional energy planning for islands : Development of a decision-aiding methodological framework and application

    Författare :Andrew Barney; Heracles Polatidis; Stefan Ivanell; Magdalena Kuchler; Jesús Ramos-Martín; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Natural Resources and Sustainable Development; Naturresurser och hållbar utveckling;

    Sammanfattning : Clear and inclusive planning guidance for island planners seeking transitions away from traditional fossil fuel based energy systems is currently needed. At present, the guidance from the scientific community has largely been provided piecemeal and with significant focus on the specifics of single islands and, more often than not, on proposed energy systems’ techno-economics.

  5. 19. Study into the Potential and Feasibility of a Standalone Solar-Wind Hybrid Electric Energy Supply System

    Författare :Getachew Bekele; Björn Palm; Philip Eames; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wind Speed; Sunshine Duration; Solar Radiation; Feasibility Study; Standalone System; Solar-Wind Hybrid; Thermal energy engineering; Termisk energiteknik;

    Sammanfattning : The tendency to use renewable energy resources has grown continuouslyover the past few decades, be it due to fear over warnings of globalwarming or because of the depletion and short life of fossil fuels or evenas a result of the interest which has developed among researchers doingscientific research into it. This work can be considered as joining any ofthese groups with an objective of giving electric light to the poorpopulation living in one of the poorest nations in the world. LÄS MER

  7. 20. Balancing variable renewable electricity generation using combined heat and power plants, large-scale heat pumps, and thermal energy storages in Swedish district heating systems

    Författare :Svante Monie; Magnus Åberg; Annica Nilsson; Joakim Widén; Magnus Wallén; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; District heating systems; Power-to-Heat; Heat pumps; Combined heat and power; Thermal energy storage; Power balance; Variable renewable electricity; Biomass fuel; Engineering Science with specialization in Civil Engineering and Built Environment; Teknisk fysik med inriktning mot byggteknik och byggd miljö;

    Sammanfattning : The global ambitions to hamper the greenhouse effect has led to ambitious targets for increasing renewable energy use. This, in combination with recent years' vast development of wind and solar power, implies that there will be significant amounts of variable renewable electricity (VRE) in future energy systems.
