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

   University essay from KTH/Industriell ekonomi och organisation (Inst.)

   Author : Simon Nordenskiöld; [2024]
   Keywords : 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;

   Abstract : 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. READ MORE

3. 2. Investigating the dynamics between the developing Nordic hydrogen market and the electricity system under uncertainty

   University essay from KTH/Energiteknik

   Author : Timon Renzelmann; [2024]
   Keywords : energy modelling; energy storage; global sensitivity analysis; hydrogen; Method of Morris; Nordics; OSeMOSYS; uncertainty analysis; energimodellering; energilagring; global känslighetsanalys; vätgas; Morris-metoden; Nordiska länder; OSeMOSYS; osäkerhetsanalys;

   Abstract : The potential of hydrogen as a clean energy carrier is hotly debated, but it promises to significantly contribute to a sustainable energy future. Hydrogen can replace fossil fuels in carbon-intensive industries, heavy transport and aviation, and support a renewable energysystem by acting as energy storage to balance intermittent supply.

4. 3. TECHNOLOGICAL ASSESSMENT OF HYDROGEN (FUTURE SCENARIOS: SOCIOLOGICAL, ENVIRONMENTAL, ECONOMIC, AND ENERGETIC ASPECTS)

   University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

   Author : Arturo Martínez Lozano; [2023-03-08]
   Keywords : ;

   Abstract : Nowadays, the term energy transition is coming into vogue, as many countries are adopting the climate change agenda across the world to achieve sustainable development goals and change from nonrenewable energies to those coming from inexhaustible energy sources, that are more efficient and less polluting. Power-to-hydrogen is an auspicious solution for storing variable renewable energies. READ MORE

5. 4. Integrating Waste Heat from Hydrogen Production Into District Heating

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Fawzi Kayali; [2023]
   Keywords : Hydrogen; Electrolysis; Waste Heat Recovery; Combined Heat and Power Plant; District Heating; Simulation; Sustainable Heating Systems; Technology and Engineering;

   Abstract : The aim of this research is to explore the feasibility of the integration of waste heat from electrolyzers within a Combined Heat and Power (CHP) plant and district heating (DH) network and suggest a practical setup for integration. With the escalating emphasis on the development of green hydrogen through electrolysis powered by renewable energy, a substantial amount of waste heat is generated, typically left unused. READ MORE

6. 5. Exhaust system for hydrogen fuelled combustion engines: effect of high-water content on the SCR vanadium catalyst

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

   Author : Cecilia Zambelli; [2023]
   Keywords : ;

   Abstract : Transportation represents a key secot in the journey towards a greener future, and alternative solutions are needed to meet the decarbonaisation need. Hydrogen internal combustion engines could represent a solution in the short-term, allowing for emission reduction with limited modification to the already existing traditional combustion engines.
