1. 1. 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. 2. 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. 3. 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.

5. 4. Characterization of potato protein and its calcium binding capacity

   University essay from Lunds universitet/Beräkningskemi; Lunds universitet/Tillämpad biokemi

   Author : Signe König; Erika Thomson; [2023]
   Keywords : Patatin; Calcium; Food supplement; Calcium Assay; Alcalase; potato protein; Applied biochemistry; Biology and Life Sciences; Technology and Engineering;

   Abstract : Calcium is essential for the human body as it has functions in the nervous system, bones and formation of teeth. Deficiency in this important nutrient can be detrimental to health and cause life-long issues. Calcium can be found in various foods, like dairy products, but certain plant-based alternatives to milk needs to be fortified with calcium. READ MORE

6. 5. Fouling modelling in a UHT unit based on plant data.

   University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

   Author : Thai Lam; [2023]
   Keywords : UHT; dairy; tubular heat exchanger; fouling development; fouling removal; food engineering; Technology and Engineering; Agriculture and Food Sciences;

   Abstract : Heat treatment of dairy products is essential for food safety, one way to perform this is ultra-high temperature (UHT) processing. During the process, macronutrients and minerals form fouling deposits which impairs heat transfer. Eventually the fouling needs to be removed chemically by alkaline and acidic detergents. READ MORE
