1. 6. 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.

3. 7. Managing Domestic Wells in Sweden. Investigating the role of domestic wells in ensuring a reliable drinking water supply and assessing their vulnerability to climate change

   University essay from Göteborgs universitet/Institutionen för geovetenskaper

   Author : Alice Stenfelt; [2023-08-28]
   Keywords : Domestic wells; Individual drinking water supply; Climate change; Sustainable development; Drinking water management; resilience water supply; Climate adaption; Sweden;

   Abstract : Domestic wells provide drinking water for a significant proportion of the population in Sweden, especially in rural areas where public water supplies are not available (Drage, 2022; Hjerne et al., 2021). Domestic wells typically lack regulation (Gunnarsdottir et al., 2020; Stoll et al. READ MORE

4. 8. 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. 9. Selected PFAS in the water treatment at the waste-to-energy plant in Umeå : Investigating concentration and composition of selected PFAS in different water treatment steps

   University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Author : Amanda Carlund; [2023]
   Keywords : ;

   Abstract : The present study investigated the changes in concentration and composition of five selected PFAS substances in the water treatment at the waste-to-energy plant in Umeå. The five PFAS were PFHxA, PFHpA, PFOA, PFHxS and PFOS. As PFAS exists in a variety of consumer products, they will to some extent end up in waste incineration. READ MORE

6. 10. 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
