  2. 16. Modelling interactions between distributed energy technologies and the centralised electricity supply system

    Author : Joel Goop; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy systems modelling; variable renewables; power systems; distributed generation; demand response; electricity storage;

    Abstract : Renewable electricity generators, such as solar photovoltaics (PVs), and variation management technologies, such as battery storage and demand response (DR) systems, can be deployed in a distributed fashion, which can benefit the overall system. Such distributed energy technologies interact with and influence the centralised generation and transmission systems. READ MORE

  4. 17. Conceptual design and investigation of hydrogen-fueled regional freighter aircraft

    Author : Kolja Seeckt; Arthur Rizzi; Petter Krus; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicle engineering; Farkostteknik;

    Abstract : This thesis presents the conceptual design and comparison of five versions of regional freighter aircraft based on the ATR 72. The versions comprise four baseline designs differing in their propulsion systems (jet/turboprop) and the fuel they use (kerosene/hydrogen). READ MORE

  5. 18. Time-dependent climate impact of production and use of wood pellets from short rotation forestry and logging residues

    Author : Charlotta Porsö; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Anthropogenic greenhouse gas (GHG) emissions are the main cause of climate change, with combustion of fossil fuels and land use changes being the main source of emissions. Wood pellets are considered a viable replacement for fossil fuels. Therefore this thesis sought to increase the knowledge base for planning new wood pellet systems. READ MORE

  6. 19. Environmental Assessment of Buildings and the influence on architectural design

    Author : Marita Wallhagen; Göran Finnveden; Mauritz Glaumann; Tove Malmqvist; Ole Jörgen Hanssen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; green building; sustainable building; environmental assessment; assessment tool; architectural design; CO2 Carbondioxide ; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

    Abstract : This licentiate thesis examines environmental assessment tools for buildings. This is done by investigating, analysing, comparing and testing how different environmental assessment tools measure the environmental performance of buildings and examining the consequences this may have on architectural design.

  7. 20. Household food waste management – Evaluations of current status and potential improvements using life-cycle assessment methodology

    Author : Anna Bernstad; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; waste management; household waste; food waste; life-cycle assessment; anaerobic digestion; systems analysis;

    Abstract : An increased understanding of the world’s limited resources and the negative environmental impacts connected to solid waste management has in recent years increased interest in separate collection and treatment of organic waste in many parts of the world. As an example, increased biological treatment of organic waste is an explicit goal within the Swedish national solid waste management strategy (SEPA, 2006) and the national environmental objectives state that 35% of all organic household waste should be treated biologically by 2010 (SEPA, 2007).
