  1. 1. Feasibility Study of Available Hydrogen Production Techniques in Sweden using Single-Issue LCA Carbon Footprint

    Master-uppsats, KTH/Industriell bioteknologi

    Författare :Beatrice Westén; [2022]
    Nyckelord :Hydrogen; biohydrogen; LCA; Single-Issue LCA; streamlined LCA; Life Cycle Assessment; Carbon Footprint; CF; Environmental System Analysis; Sweden; holistic; future scenarios; Vätgas; biovätgas; LCA; Single-Issue LCA; streamlined LCA; Life Cycle Assessment; Carbon Footprint; CF; Environmental System Analysis; Sverige; holistisk; framtida scenarios;

    Sammanfattning : Sverige har som mål att bli helt fossilfri till år 2045. Energymyndigheten har därför tagit fram ett förslag till Vätgasstrategi för att ställa om vätgasproduktionen till att vara helt fossilfri till 2045. Idag används ca 180 000 ton vätgas, vilket motsvarar ett energiinnehåll på ca 6 TWh. LÄS MER

  3. 2. Climate impact of bioH2 production from biogas using CO2 mineralization for carbon capture and storage

    Kandidat-uppsats, SLU/Dept. of Energy and Technology

    Författare :Hera Harðardóttir; [2022]
    Nyckelord :carbon capture and storage; carbon dioxide mineralization; biohydrogen production; global warming potential; greenhouse gases;

    Sammanfattning : Carbon dioxide (CO2) concentrations in the atmosphere are increasing and are now higher than they have ever been, mostly because of CO2 released from burning fossil fuels for energy. Global energy demand will continue to rise in the future, resulting in increased carbon emissions. LÄS MER

  4. 3. A future introduction of biohydrogen to the Swedish energy system

    Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Fritiof Pröjts Erlandsson; [2020]
    Nyckelord :Energy stragegy; emission reduction; Biohydrogen; Sweden; Earth and Environmental Sciences;

    Sammanfattning : Biohydrogen is increasingly being explored as part of strategies to achieve deep emission reductions. While much research has focused on the technical dimension of biohydrogen, fewer efforts have positioned it in larger contexts. LÄS MER

  5. 4. Biohydrogen and Volatile Fatty Acids Production form Food Waste Hydrolysate

    Magister-uppsats, Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Författare :Yaswanth Lingam; [2018]
    Nyckelord :Biohydrogen; Food waste; volatile fatty acids; acetic acid; wastewater;

    Sammanfattning : This work focused a pH readjustment strategy has been applied for the enhancement ofbiohydrogen production form food waste hydrolysate in a semi-pilot scale bioreactor seededwith selectively enriched mixed microbial culture. Different initial pH (pH 6, pH 7, and pH8) was selected for biohydrogen production from FW. LÄS MER

  7. 5. Evaluation of the software SuperPro Designer through simulation of a biohydrogen production process

    Master-uppsats, Lunds universitet/Bioteknik; Lunds universitet/Kemiska institutionen

    Författare :Erik Bergman; [2016]
    Nyckelord :Teaching; Academia; Biofuel; Biohydrogen; Bioprocess; Software; Biotechnology; Process Simulation; SuperPro; SuperPro Designer; Bioteknik; Technology and Engineering;

    Sammanfattning : A simulation in bioprocess technology was carried out in order to evaluate the accessibility and adequacy of the simulation software SuperProDesigner used on an academic level. This was done by recreating an existing process and studying the results as well as observing the diculties and limitations along the way. LÄS MER
