    Sammanfattning : The European Energy system is currently transitioning towards a reduced use of fossil fuels and increasing use of renewable energy. Hydrogen as energy carrier for renewable electricity has a potential to play a significant role in this transition. LÄS MER

  3. 2. Underground Thermal Energy Storage for District Heating : A Feasibility Study

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Emma Arnfelt; [2022]
    Nyckelord :;

    Sammanfattning : Global warming is one of the largest challenges and most important issues within the energy sector. As the society’s demand for energy increases, the environmental impact must continue to decrease to reach global targets. LÄS MER

    Sammanfattning : 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. LÄS MER

  5. 4. Techno-economic Pricing model for Carbon Neutral Fuels as Seasonal Energy Storage

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Ananya Saraf; [2021]
    Nyckelord :Hydrogen; seasonal storage; geological storage; carbon-neutral fuels; Vätgas; säsongslagring; geologisk lagring; koldioxidneutrala bränslen;

    Sammanfattning : Green hydrogen produced through electrolysis of excess renewable energy is a promising seasonal energy storage solution with the potential to decarbonize the energy sector. However, it has physical properties that make it difficult to store and transport on a large scale for grid scale storage applications. LÄS MER

  7. 5. Konvertering av oljelager till värmelager : I Sundsvalls fjärrvärmesystem

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Love Hagstedt; [2020]
    Nyckelord :TES; Thermal Energy Storage; District Heating; Waste to heat; conversion; Transient heat flow; Rock cavern; Termiskt värmelager; Energi lager; överproduktion; oljelager; värmelager; Fjärrvärme; bergrum; transient värmeflöde; värmeflöde;

    Sammanfattning : This study has examined how an oil storage could be converted into a thermal heat storage (TES). Focus was put on the transient thermal heat flow that occurs during the early years when using a rock cavern as a TES. First existing literature were studied to learn from earlier experiences. LÄS MER
