   Abstract : 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. READ MORE

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

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Emma Arnfelt; [2022]
   Keywords : ;

   Abstract : 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. READ MORE

   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

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

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

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

   Abstract : 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. READ MORE

6. 5. Rock cavern as thermal energy storage

   University essay from Luleå tekniska universitet/Energivetenskap

   Author : Simon Berglund; [2020]
   Keywords : Rock cavern; Waste heat; District heating; Intermittent operation; Sustainability; Heat storage; Carbon dioxide reduction; Bergrum; Spillvärme; Fjärrvärme; Intermittent drift; Hållbarhet; Värmelagring; Koldioxid reducering;

   Abstract : In the fall of 2019, a comprehensive idea study was conducted on heat storage in two rock caverns located at Näsudden in Skelleftehamn and was part of the project course "Energiteknik, huvudkurs" at Luleå University of Technology. This idea study investigated the conditions of using waste heat from Boliden AB:s copper smeltery (Rönnskär) and storing this waste heat in two rock caverns and use them as seasonal thermal storage tanks, with the purpose of using the heat in the nearby district heating network, thus replacing some of the oil burned at Rönnskär.
