    Abstract : There has recently been an increased interest in hydrogen, both as a solution for seasonal energy storage but also for implementations in various industries and as fuel for vehicles. The transition to a society less dependent on fossil fuels highlights the need for new solutions where hydrogen is predicted to play a key role. READ MORE

  2. 2. Aviation’s future energy requirements

    University essay from Lunds universitet/Trafikflyghögskolan

    Author : Leonard Holmgren Holm; [2021]
    Keywords : Aviation fuels; Sustainable aviation fuels; Hydrogen power; Electric aircraft; Environmental impact; FLYL01; Technology and Engineering;

    Abstract : Flygindustrin närmar sig ett vägval där sektorn kommer behöva bestämma sig för vilken typ av framtida energimöjligheter den ska använda sig av. En väg är att även fortsättningsvis använda sig konventionellt flygbränsle vilket med stor sannolikhet kommer leda till fortsatt ökande utsläpp globalt, och den andra vägen leder sektorn till hållbart flygbränsle, vätgasdrift och batteridrivna elektriska flygplan.

  3. 3. Performance Evaluation of a Photovoltaic/Thermal (PVT) Collector with Numerical Modelling

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

    Author : Mila Ebrahim; [2021]
    Keywords : Solar energy; Renewable energy; Photovoltaic thermal collector; PV Thermal; PVT Collector; Performance; Numerical modelling; COMSOL Multiphysics; Ground Source Heat Pump; Solenergi; Förnybar energi; kominerad solcell solfångare; PVT panel; Prestanda; Numerisk modellering; COMSOL Multiphysics; Bergvärme;

    Abstract : In Photovoltaic/Thermal (PVT) technology, both PV and solar thermal technology are integrated in the same module for simultaneous electricity and heat production. Research has shown that there are multiple benefits from integrating PVT collectors with a ground source heat pump (GSHP) system, since it allows for seasonal storage of thermal energy over the year.
