  2. 16. Light-Metal Hydrides for Hydrogen Storage

    Author : Martin Sahlberg; Yvonne Brandt Andersson; Björgvin Hjörvarsson; Björn Hauback; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Metal-hydrogen compounds; hydrides; hydrogen storage; X-ray diffraction; neutron diffraction; thermal desorption spectroscopy; Chemistry; Kemi; Inorganic chemistry; Oorganisk kemi; Inorganic Chemistry; oorganisk kemi;

    Abstract : Demands for zero greenhouse-gas emission vehicles have sharpened with today’s increased focus on global warming. Hydrogen storage is a key technology for the implementation of hydrogen powered vehicles. READ MORE

  4. 17. Thermal response test : method development and evaluation

    Author : Signhild Gehlin; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Abstract : Since the first introduction of thermal response tests with mobile measurement devices in Sweden and USA in 1995, the method has developed and spread in North America and Europe. Thermal response tests have so far been used primarily for in situ determination of design data for BHE (borehole heat exchanger) systems, but also for evaluation of grout material, heat exchanger types and groundwater effects.

  6. 19. Mixing and Stagnation in Drinking Water Storage Tanks

    Author : Ola Nordblom; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; storage tank; service reservoir; jet mixing; khappa - epsilon model; stagnation; tracer test; temperature measurement; thermal stratification; buoyant jets; CFD model;

    Abstract : This thesis contributes to studies of the assessment of mixing conditions in drinking water storage tanks and analyses of parameters governing mixing rates and formation of stagnant zones. The work also contributes to a validation of Computational Fluid Dynamics (CFD) models of jet-forced mixing in storage tanks under neutral and thermally stratified conditions. READ MORE

  7. 20. Exploring Devices for Molecular Solar Thermal Energy Storage Systems

    Author : Zhihang Wang; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar energy; photochromic molecule; dihydroazulene vinylheptafulvene photoswitches; energy conversion; norbornadiene quadricyclane photoswitches; energy storage;

    Abstract : The sun is considered to be one of the most abundant and renewable sources of energy. During recent last decades, technologies for solar energy capture and storage have been significantly investigated. An attractive way to store solar light, is to use photochromic molecules that can capture and store solar energy in chemical bonds. READ MORE
