  1. 1. Dynamics of Energy Systems - Methods of analysing technology change

    University dissertation from Environmental and Energy Systems Studies, Lund university

    Author : Lena Neij; [1999]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy research; evaluation; market transformation; PV modules; wind power; experience curves; air-distribution; lighting; vintage models; sustainable energy; renewable energy; energy efficiency; Energy; energy system; Energiforskning; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

    Abstract : Technology change will have a central role in achieving a sustainable energy system. This calls for methods of analysing the dynamics of energy systems in view of technology change and policy instruments for effecting and accelerating technology change. In this thesis, such methods have been developed, applied, and assessed. READ MORE

  4. 4. Molecular Solar Thermal Energy Storage System: Evaluation of Different Candidates

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Zhihang Wang; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy storage and release; Vinylheptafulvene; Catalyst; Quadricyclane; Solar Energy; Thermal dynamics; Molecular switches; Azobenzene; Norbornadiene; Energy conversion; Dihydroazulene;

    Abstract : The development of solar energy can potentially meet the growing requirements for a global energy system beyond fossil fuels, however necessitates new scalable technologies for solar energy storage. One approach is the development of energy storage systems based on molecular photoswitches, so-called molecular solar thermal energy storage (MOST). READ MORE

  5. 5. Energy Savings Using a Direct-Current Distribution Network in a PV and Battery Equipped Residential Building

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Patrik Ollas; [2020]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Efficiency; System Performance; PV Utilisation; Battery Energy Storage System; Residential Buildings; Energy Savings; Direct-Current Distribution; Solar Photovoltaic System; Battery Modeling;

    Abstract : Energy from solar photovoltaic (PV) are generated as direct current (DC) and almost all of today’s electrical loads in residential buildings, household appliances and HVAC system (Heating Ventilation and Air-conditioning) are operated on DC. For a conventional alternating current (AC) distribution system this requires the need for multiple conversion steps before the final user-stage. READ MORE
