1. 1. Leveraging green hydrogen to decarbonise the aviation industry : A case study on electrofuels in Sweden

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

   Författare :Jakob Bergene; Jonathan Bruchhausen; [2023]
   Nyckelord :Electrofuel; e-fuel; electrokerosene; e-kerosene; SAF; sustainable aviation fuel; sustainable aviation; complementarity formation mechanisms; technology value chains; TVC; Techno-economic analysis; TEA; Elektrobränsle; e-bränsle; elektrofotogen; e-fotogen; SAF; sustainable aviation fuel; sustainable aviation; komplementära formationsmekanismer; technology value chains; TVC; Techno-economic analysis; TEA;

   Sammanfattning : For the EU to reach its 2050 climate targets the aviation industry that is highly dependent on fossil fuels needs to drastically reduce its emissions. In the decarbonisation of the aviation industry drop-in sustainable aviation fuels (SAFs) have been identified as a promising solution to abate the industry’s emissions. LÄS MER

3. 2. Accelerating the Green Transition - Investigating the Feasibility of E-Fuel Production Connected to a CHP Plant

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Johanna Scholtz; Alice Maillard; [2023]
   Nyckelord :CCU; CHP plant; e-fuels; e-methane; e-methanol; e-kerosene; Technology and Engineering;

   Sammanfattning : The overall purpose of this thesis is to investigate the feasibility of producing electrofuels from CO2 and H2 in connection to a CHP plant equipped with carbon capture technology. This is done by investigating the production of e-methane, e-methanol and e-kerosene from captured CO2 and H2 produced from electrolysis. LÄS MER

4. 3. Linking the selectivity of varying surface phases of a real palladium catalyst toward specific methane oxidation pathways with Ambient Pressure X-ray Photoelectron Spectroscopy

   Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Författare :Ulrike Küst; [2023]
   Nyckelord :APXPS; catalysis; palladium; methane; Physics and Astronomy;

   Sammanfattning : The study of heterogeneous catalysis, especially within methane oxidation, is of high importance in order to more efficiently remove unburned methane from bio-fuel exhausts. This is relevant as bio-fuel engines will replace those driven by fossil fuels in the coming decades. LÄS MER

5. 4. Biogas Potential in the North of Sweden : Inventory and Techno-Economic Assessment of Substrates for an Increased Biogas Production in Norrbotten

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Alma Fahlén Hammar; [2023]
   Nyckelord :Biogas; anaerobic digestion; AD; Norrland; bioenergy; fossil-free; chemical engineering; Chemistry; Technology and Engineering;

   Sammanfattning : Great investments are planned in the north of Sweden the coming years, not the least in the county of Norrbotten where the projects collectively are referred to as the green transition due to the focus on fossil-free techniques. But to be able to secure a sustainable energy supply and reach the goal set by the member states of the European Union of a carbon dioxide neutral union in 2050 the production of alternative energy sources needs to intensify.

7. 5. Understanding the potential future capacity of distributing green steel solutions - current knowledge and future challenges

   Magister-uppsats, Linnéuniversitetet/Institutionen för biologi och miljö (BOM)

   Författare :Heba Alwan; [2023]
   Nyckelord :Carbon dioxide CO2 ; greenhouse gas GHG emissions; Steelmaking fossil-free; direct hydrogen reduction; Sustainability transitions.;

   Sammanfattning : Transitioning from the conventional steel process to a direct hydrogen reduction process in the steel industry is a significant step towards reducing carbon dioxide emissions and achieving greater sustainability. The process involves using hydrogen gas as a reducing agent instead of carbon to remove oxygen from the iron ore. LÄS MER
