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

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

   Author : Jakob Bergene; Jonathan Bruchhausen; [2023]
   Keywords : 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;

   Abstract : 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. READ MORE

3. 7. Sustainable Polymer Production: Investigating Synthesis and Copolymerization of Cyclic Ketene Acetals

   University essay from KTH/Kemiteknik

   Author : Soufian Bourraman; Stella Staffas; Adam Brandt; Simon Isaksson; [2023]
   Keywords : Monomers; polymers; radical; radical ring opening polymerization; polymerization; BMDO; MMA; MVL; MBL; comonomer; copolymer; rROP; sustainable; biobased; degradable; monomer synthesis; plastic; polyester; bulk; solution; NMR; FTIR; TGA; DSC; SEC; hydrolysis; molecular weight; diol; ester bonds;

   Abstract : The large amount of non-degradable plastic waste has become a significant environmental concern, leading to an increased need for degradable plastics. Here in, to create degradable polymers, polyesters were produced through radical ring opening polymerization using cyclic ketene acetals. READ MORE

4. 8. Effects of soil factors on pioneer bryophyte species composition

   University essay from Lunds universitet/Examensarbeten i biologi

   Author : Dora Mijić; [2023]
   Keywords : Biology and Life Sciences;

   Abstract : Bryophytes play a significant role in various ecological processes, including soil succession and colonization after disturbances. Although they are commonly believed to take up nutrients from soil solutions rather than the soil itself, the influence of soil on their growth and distribution is evident from previous studies.

5. 9. Modeling of an Electrolysis System for Techno-Economic Optimization of Hydrogen Production

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

   Author : Jürgen Köstlbacher; [2023]
   Keywords : Hydrogen; Hydrogen Production; Green Hydrogen; LCOH; Electrolysis; PEM; AEL; MILP; Optimization; Techno-Economic Analysis; Cost Optimization; PPA; vätgas; vätgasproduktion; grön vätgas; LCOH; elektrolys; PEM; AEL; MILP; optimering; tekniskekonomisk analys; kostnadsoptimering; PPA;

   Abstract : In face of climate change, Europe and other global actors are in the process of transitioning to carbon-neutral economies, aiming to phase out of fossil fuels and power industries with renewable energies. Hydrogen is going to play a crucial role in the transition, replacing fossil fuels in hard-to-decarbonize industries and acting as energy carrier and energy storage for renewable electricity.

6. 10. Modelling and Simulation of Hydrogen Electrolyzers for Power System Applications

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Javier Vinuelas Ferrando; [2023]
   Keywords : ;

   Abstract : The rapid increase in the share of intermittent renewables in the energy mix is exacerbating the complexity of the grid stability. To facilitate the inclusion of these green technologies and achieve the climate targets set by the EU, the generation and storage of hydrogen through electrolysis may be crucial. READ MORE
