1. 1. Navigating Sustainability : A case study exploring alternative energy sources for maritime shipping

   Master-uppsats, KTH/Industriell ekonomi och organisation (Inst.)

   Författare :Simon Nordenskiöld; [2024]
   Nyckelord :Maritime shipping; Alternative energy sources; Alternative fuels; Hydrogen-based fuels; Sustainable shipping; Electrofuels; Electro-methanol; Liquid Hydrogen; Electro-ammonia; Sails; Wind; Technological Innovation System; Sjöfart; Alternativa energikällor; Alternativa bränslen; Vätebaseradebränslen; Hållbar sjöfart; Elektrobränslen; Elektrometanol; Flytande väte; Elektroammoniak; Segel; Vind; Technological Innovation Systems;

   Sammanfattning : This master thesis studies alternative energy sources for maritime shipping in Sweden. With current climate goals, and a need for change, the maritime sector currently undergoes intense transitions. For shipping companies to lower their carbon footprint, the need to replace non decarbonised fuels is hence critical. LÄS MER

3. 2. Evaluating the Performance of a Solar Thermal Field: A Case Study with Proposed Improvements

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Anton Segovia Lundh; [2023]
   Nyckelord :solar thermal; concentrated solar power CSP ; renewable energy; performance evaluation; Technology and Engineering;

   Sammanfattning : Given the urgency of climate change, alternative energy sources, and policy strategies are needed to reach the net-zero emission goals and halt global warming. Solar thermal energy is a renewable and abundant energy source that could be a part of the solution. LÄS MER

4. 3. Flexible Sector Coupling (FSC) of Electrical and Thermal Sectors via Thermal Energy Storage (TES) : A Case Study on Oskarshamn Energi

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

   Författare :Raúl Calvo García; Jose María Marín Arcos; [2023]
   Nyckelord :Flexible sector coupling FSC ; district heating DH ; thermal energy storage TES ; heat pump HP ; capacity optimization; dispatch optimization; open-access tools; Flexibel sektorkoppling; fjärrvärme; termisk energilagring; värmepump; kapacitetsoptimering; leveransoptimering; verktyg med öppen tillgång;

   Sammanfattning : The integration of distributed energy sources and systems is of high relevance for the transition towards a more sustainable energy system. Taking into consideration the  amount of emissions produced by the heating sector, which account for at least half of the energy demand in buildings, district heating systems have the potential to play a key role in the transition, by enabling the integration of various energy sources and provide flexible energy services to the grid.
