  1. 1. Exploring Devices for Molecular Solar Thermal Energy Storage Systems

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Zhihang Wang; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy storage; norbornadiene quadricyclane photoswitches; photochromic molecule; Solar energy; energy conversion; dihydroazulene vinylheptafulvene photoswitches;

    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

  2. 2. Norbornadienes for Solar Thermal Energy Storage and New Applications

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Ambra Dreos; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; thermal energy storage; molecular logic; Solar energy; molecular switch- es; energy conversion; quadricyclane; molecular keypad locks; norbornadiene;

    Abstract : The energy demand worldwide is steadily increasing, therefore it is fundamental to efficiently utilise renewable energy resources. Energy storage technologies are partic- ularly relevant in order to be able to exploit renewable energy resources such as solar energy, since these are typically intermittent and not evenly distributed.

  3. 3. Norbornadienes for molecular solar thermal energy storage

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Maria Quant; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; energy storage; solar energy; norbornadiene - quadricyclane photo switches; synthesis of norbornadienes.;

    Abstract : Over the last decade, there has been great scientific progress in terms of harvesting solar energy but the area of storing energy is still facing challenges. One approach to store solar energy is via photoinduced isomerization of chemical bonds, referred to as molecular solar thermal energy storage (MOST). READ MORE

  4. 4. A novel solar-driven system for two-step conversion of CO2 with ceria-based catalysts

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Bo Wei; KTH.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CO2 conversion; solar; ceria; thermogravimetric test; exergy analysis; simulink; fluidized bed; gas-solid flow; simulation; Energiteknik; Energy Technology;

    Abstract : Global warming is an unequivocal fact proved by the persistent rise of the average temperature of the earth. IPCC reported that scientists were more than 90 % certain that most of the global warming was caused by increasing concentrations of greenhouse gases (GHG) produced by human activities. READ MORE

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

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Lukas Aichmayer; KTH.; [2018]
    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; Energiteknik; Energy Technology;

    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
