  1. 1. Investigation of new refrigerants for a large-scale heat pump and evaluation of system performance

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Hanna Grahn; Matilda Eriksson; [2023]
    Nyckelord :Large-scale heat pump; refrigerant; COP;

    Sammanfattning : Heat production accounted in 2021 for 50 % of the energy end use globally, where a strongconnection to fossil sources still exists. Large-scale electrical heat pumps can therefore have akey role in the energy system to enable a decreased reliance on fossil fuels and at the same timecontribute to stable system when incorporating more intermittent renewable sources.

  3. 2. Production and harvesting of volatile jet fuel precursors from Synechocystis sp. PCC 6803

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Johan Sjölander; [2019]
    Nyckelord :Jet fuel; isoprene; isobutene; cyanobacteria; solar fuel; photobioreactor; photosynthesis;

    Sammanfattning : The world is currently faced with the enormous challenge of slowing down human triggered global warming. As the global energy demand increases, there is an urgent need for renewable and carbon-neutral fuel-sources. LÄS MER

  4. 3. Photosynthetic production of raw materials for jet fuel using cyanobacteria : In vivo study of recombinant oleate hydratase for isobutene production

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Siri Norlander; [2018]
    Nyckelord :cyanobacteria; oleate hydratase; biofuel; protein expression; isobutene; isobutanol; synechocystis;

    Sammanfattning : Aviation accounts for a significant part of the world’s CO2 emission from the transport sector, but sustainable jet fuels are not as developed or as commonly used as renewable fuels for road vehicles. Biofuels produced through photosynthesis in cyanobacteria are of interest to help solve the pressing issue of CO2 emissions and increased global warming. LÄS MER
