  2. 1. Life performance assessment methodologies for combined solar energy technologies : a case study on system parts in nordic climates

    Author : Bojan Stojanovic; Christer Sjöström; Björn Karlsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; life performance; assessment; combined solar energy technologies; degradation; component and system performance; Building engineering; Byggnadsteknik; Materials science;

    Abstract : The main questions concerning energy technologies today are their economical and environmental impacts. These entities are (at the present) assessed on the basis that operations proceed as newly installed/designed systems, during an assumed working life period. READ MORE

  4. 2. Island-based Polygeneration Systems : On the Feasibility of Solar-Biomass-driven Distributed Concepts

    Author : Moritz Wegener; Anders Malmquist; Andrew R. Martin; Antonio Isalgué; Natasa Nord; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polygeneration; Distributed energy systems; Biomass; Solar energy; PV-Battery; Small-scale energy systems; techno-economic analysis; Island-based systems; Energy Technology; Energiteknik;

    Abstract : The colossal risks and challenges posed by climate change require innovative solutions that must fulfil energy service demands sustainably. The concept of small-scale, biomass-based polygeneration (SBP) is one such technological approach, which optimizes locally supplied fuels to provide several energy services like electricity, heating, cooling, potable water, and/or bio-chemical products.
