1. 1. Comparative Analysis of On-site vs Off-site green-Hydrogen Value Chain Scenarios to cover projected Aviation demand : A case for Toulouse Blagnac Airport in France

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

   Författare :Stathis Alexandrou; [2023]
   Nyckelord :Hydrogen Production; Value Chain Analysis; Levelized Cost of Hydrogen Production LCOH ; Hydrogen for Aviation; France; Toulouse Airport; Analys av vätgasens värdekedja; kostnader för vätgasens försörjningskedja; LCOH; flytande vätgas; vätgas för luftfarten; Frankrike; Toulouse Airport; ;

   Sammanfattning : Amidst the efforts to mitigate the energy-related carbon emissions of human activities and pursuing a net-zero future by 2050, the aviation sector, as part of a wider group of hard-to-decarbonize sectors is responsible for 12% of all the transportation emissions globally. Green Hydrogen as a zero-emissions alternative fuel from water and renewable energy serves as a prime candidate to replace conventional aviation fuels and lead the way towards carbon-free flights.

3. 2. Kväve och Mikroplast i anlagda våtmarker

   Kandidat-uppsats, SLU/Dept. of People and Society

   Författare :Anna Wiklund; Lisa Kröss; [2023]
   Nyckelord :Kväve; mikroplast; sediment; anlagda våtmarker; föroreningar; svavelväte; norden och skåne län; SLU;

   Sammanfattning : De anlagda våtmarkerna genomgår en internationell kris, detta bör tas på allvar annars blir konsekvenserna förödande. De anlagda våtmarkernas syfte är bl. a öka biodiversitet och få en varierande landskap samt kunna kontrollera vattennivåer, föroreningar och näring. Våtmarker fungerar som naturliga reningsverk i naturen. LÄS MER

4. 3. A Techno-Economic Case Study of the Implementation of Hydrogen Technology in Connection to a CHP Plant

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Kristina Häggström Wedding; Amanda Kander; [2023]
   Nyckelord :Hydrogen Technology; Electrolyzer; Fuel Cell; Ancillary Services; Electricity Markets; Power Balancing; Balancing Markets; Power to Gas; Power to Power; Combined Heat and Power; District Heat; Heat Utilization; Flexibility; Optimization; Technology and Engineering;

   Sammanfattning : With climate change as the main driving force, the energy system is currently undergoing changes. Both the share of renewable resources used to produce electricity and the overall electrification is increasing. A way to handle the resulting challenges from more intermittent electricity production is by the implementation hydrogen technology. LÄS MER

5. 4. Research on the Hydrothermal Conversion of Xylose Catalysed by CO2-H2O into Furfural

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

   Författare :Robert Liao; [2023]
   Nyckelord :;

   Sammanfattning : Agricultural waste treatment and carbon dioxide emissions from fossil fuel combustion have been critical challenges for sustainable development. This work is part of a study on converting straw into biofuels, which involves using xylose as the material, carbon dioxide (CO2) as the catalyst, and water (H2O) and Gamma-Valerolactone (GVL) as the solvent to produce furfural through hydrothermal conversion.

7. 5. A study on solar assisted hydrogen production with seawater electrolysis for British household heating applications

   Master-uppsats, KTH/Kraft- och värmeteknologi

   Författare :Lucas Chaubier; [2022]
   Nyckelord :;

   Sammanfattning : In the United Kingdom, 85% of households rely on natural gas for space/water heating and cooking. On average, the yearly demand for one household for providing heat from natural gas is 13300 kWh. LÄS MER
