  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. 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.

  4. 3. Enhancing Mineral Carbonation of Olivine with CO2

    University essay from KTH/Kemiteknik

    Author : Ikaros Altantzis; [2023]
    Keywords : CO2 sequestration; Dissolution rate; Mineral carbonation; Olivine; Particle size; CO2-inlagring; Upplösningshastighet; Mineral kolsyrning; Olivin; Partikelstorlek;

    Abstract : Koldioxidutsläpp (CO2) från energiproduktionsindustrin och transportsektorn globalt påverkar miljön negativt. Länder har enats om att minska utsläppen för att nå målet om en genomsnittlig temperaturökning på 1,5 °C till 2030. READ MORE

  5. 4. Desulphurisation of cement flue gases

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Ellen Sjöstrand; [2023]
    Keywords : Flue Gas Desulphurisation; FGD; gypsum; cement;

    Abstract : Flue gas desulphurisation (FGD) is a crucial method to minimise the SO2 emissions from industrial processes. The FGD system utilise an alkaline sorbent to remove SO2 from the flue gases. Calcium in form of limestone is a commonly used sorbent where gypsum is produced asa by-product. READ MORE

  6. 5. Solubility of Wood Xylans, Effect of pH and Concentration

    University essay from KTH/Glykovetenskap

    Author : James Carlsson; [2022]
    Keywords : Xylan; Wood; Solubility; Dynamic Light Scattering; Filtration; Xylan; Trä; Löslighet; Dynamisk ljusspridning; Filtrering;

    Abstract : Lösligheten av xylaner utvunna från trä undersöktes med Dynamisk Ljusspridning i syfte att observera eventuella förändringar i hydrodynamisk volym och ζ-potential. Xylaner extraherade från bok, björk och gran användes, där alkalisk extraherad bok erhölls kommersiellt och prover från björk och gran extraherades i förhand med subkritiskt vatten och alkalisk extraktion.
