  1. 11. Power-to-Gas and zero-emission buses in Uppsala : challenges and Opportunities from a techno-economic perspective

    University essay from SLU/Dept. of Energy and Technology

    Author : Mårten Rosell; [2021]
    Keywords : Power-to-gas; bränsleceller; medicinsk syrgas; modellering; lönsamhet;

    Abstract : This thesis has explored the use of power-to-gas technology as a means to produce hydrogen for fuel cell electric buses. The municipal council of Uppsala are looking at options to electrify the local city and regional bus fleet but have been faced with power capacity constraints on the local electrical grid. READ MORE

  3. 12. The influence of passive measures on the highly demanding room climate requirements of a museum building in terms of sustainability

    University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Author : Jasmin Jost; [2021]
    Keywords : museum; museum climate; conservation requirements; climate risk assessment; indoor environment; thermal comfort; thermal mass; moisture buffering; hygroscopic materials; life cycle assessment LCA ; Technology and Engineering;

    Abstract : In the exhibition space of a museum, a compromise between the requirements for the preservation of cultural goods and thermal comfort criteria for visitors has to be applied. Such a high level of control without allowing fluctuations in temperature and relative humidity poses a big challenge to the air conditioning systems to maintain these very specific hygrothermal conditions.

    Author : Felix Lindblom; [2021]
    Keywords : ;

    Abstract : In December 2015 Scania Oskarshamn started production in their new facility for the body in white (BiW) production. Heat capacity control (HCC) is used to control the RSW process for all the welding robots in this facility for BiW at Scania Oskarshamn. READ MORE

  5. 14. Aqua Ammonia as Secondary Fluid in Ice Rink Applications

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Brianna Kilberg; [2020]
    Keywords : Ice rink; secondary fluid; aqua ammonia; ammonia water; thermophysical properties; corrosion; pressure drop; pumping power; refrigeration;

    Abstract : Refrigerant management is crucial in the attempts to slow climate change. Emissions from the refrigeration sector are primarily due to poor management and unsafe destruction of refrigerants currently in circulation. Safe refrigerant management and improving system operating efficiency can result in a reduction of emissions. READ MORE

  6. 15. Techno-economic analysis of demand flexibility from heat pumps for multi-family buildings in Sweden based on two case studies

    University essay from KTH/Energiteknik

    Author : Hsin-Ting Ko; [2020]
