  1. 1. Solar receiver development for gas-turbine based solar dish systems

    Author : Lukas Aichmayer; Björn Laumert; Konstantinos Kyprianidis; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concentrating solar power; volumetric solar receiver; development; experimental evaluation; validation; Koncentrerad solkraft; volumetrisk solmottagare; utveckling; experimentell utvärdering; validering; Energy Technology; Energiteknik;

    Abstract : Small-scale concentrating solar power plants such as micro gas-turbine based solar dish systems have the potential to harness solar energy in an effective way and supply electricity to customers in remote areas. In such systems, the solar receiver transfers the power of concentrated solar radiation to the working fluid of the power conversion cycle. READ MORE

  2. 2. Solar heat pump systems for heating applications : Analysis of system performance and possible solutions for improving system performance

    Author : Stefano Poppi; Per Lundqvist; Chris Bales; Kai Siren; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar heat pump systems; techno-economics; solar thermal; system improvements; cost-effectiveness; Energiteknik; Energy Technology; MacSheep;

    Abstract : Solar heat pump systems (SHPs) are systems that combine solar energy and heat pumps. SHPs have been investigated for several decades and have been proven to increase the share of renewable energy and reduce electric energy demand in residential heating applications. READ MORE

  3. 3. Solar integrated heating systems: Applications in buildings and industries

    Author : Puneet Kumar Saini; Joakim Widén; Xingxing Zhang; Frank Fiedler; Thomas Olofsson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar heating systems; Renewable heating systems; Decarbonization; Solar thermal; Techno-economic analysis; Thermal energy storage.; Engineering Science with specialization in Civil Engineering and Built Environment; Teknisk fysik med inriktning mot byggteknik och byggd miljö;

    Abstract : “Heat is half” of the global final energy consumption, and the decarbonization of the heating sector is critical to achieving climate goals. This thesis employs a system modelling approach to evaluate renewable heating systems. READ MORE

  4. 4. Cosmogenic radionuclides in environmental archives – A paleo-perspective on space climate and a synchronizing tool for climate records

    Author : Florian Mekhaldi; MERGE: ModElling the Regional and Global Earth system; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Comogenic radionuclides; 10Be; 36Cl; Solar energetic particles; Solar storms; Paleoclimate; Time-scales; Solar activity;

    Abstract : The Sun is the primary source for Earth’s climate system. Its fluctuations in irradiance are also known to have an impact on climate. In addition, changes in solar activity modulate the atmospheric production rates of cosmogenic radionuclides (e.g. READ MORE

  5. 5. Gas-filled, flat plate solar collectors

    Author : Johan Vestlund; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mechanical stresses; collector material; heated cavity; Modelling; Solar collectors;

    Abstract : This work treats the thermal and mechanical performances of gas-filled, flat plate solar collectors in order to achieve a better performance than that of air filled collectors. The gases examined are argon, krypton and xenon which all have lower thermal conductivity than air. The absorber is formed as a tray connected to the glass. READ MORE
