  1. 11. Research on the Hydrothermal Conversion of Xylose Catalysed by CO2-H2O into Furfural

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

    Author : Robert Liao; [2023]
    Keywords : ;

    Abstract : Agricultural waste treatment and carbon dioxide emissions from fossil fuel combustion have been critical challenges for sustainable development. This work is part of a study on converting straw into biofuels, which involves using xylose as the material, carbon dioxide (CO2) as the catalyst, and water (H2O) and Gamma-Valerolactone (GVL) as the solvent to produce furfural through hydrothermal conversion.

  2. 12. Decarbonisation of service vessels in offshore wind power through power-to-X self-sufficiency

    University essay from Lunds universitet/Miljö- och energisystem

    Author : Clemens Kellander; Ludvig Fredriksson; [2023]
    Keywords : Alternative fuels; compressed hydrogen; battery; production; energy storage; operation and maintenance; O M; offshore; wind power; service vessel; crew transfer vessel; CTV; service operations vessel; SOV; decarbonisation; global warming potential; life cycle; Technology and Engineering;

    Abstract : This report examines the possibilities of decarbonising operation & maintenance vessels for a prospective floating offshore wind power park at the Utsira Nord site in Norway, through self-sufficient energy carrier production utilizing power-to-X-solutions. Possible alternative fuels are identified as compressed hydrogen, batteries, liquid hydrogen, ammonia, methanol, and biofuels, out of which the former two are the subject for thorough investigation in this report.

  3. 13. Trade-induced Environmental Impacts Connected to a Policy Promoting Agricultural Biofuels in Sweden; A sensitivity analysis on an Agent-based Life Cycle Assessment

    University essay from Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Author : Fanny Elfgren; [2023]
    Keywords : AB-LCA; Life Cycle Assessment; Energy crops; Trade; Import; Biofuel; Sensitivity Analysis; Earth and Environmental Sciences;

    Abstract : The demand for biofuels is increasing as a result of increased climate mitigation ambitions aiming to replace the use of fossil fuels. To meet the increasing demand, energy crops grown on agricultural land used to produce biofuels is getting more and more attention. READ MORE

  4. 14. Climbing to new heights : The importance of considering passengers on the flight towards more sustainable forms of aviation

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

    Author : Eleanor Dowds; [2023]
    Keywords : Sustainable aviation; passengers; attitudes; SAF; biofuels; Diffusion of Innovation; Hållbart flyg; passagerare; attityder; SAF; biobränsle; Diffusion of Innovation;

    Abstract : Within the commercial aviation industry, with its ever increasing global carbon footprint rising with consumer demand, the need for more sustainable forms of aviation has become more necessary than ever. With growing demands for emission reductions and better energy management practices across all industries in initiatives such as the Paris Agreement, there has never been a more pressing time to explore the existing and potential pathways towards more sustainable forms of aviation.

  5. 15. Combining GHG Emissions and Soil Carbon Changes as a Single Metric to Evaluate Agricultural Policy Promoting Biomass for Biofuels

    University essay from Lunds universitet/Miljövetenskaplig utbildning; Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Author : Malin Lane; [2022]
    Keywords : Gräsvallar; klimatpåverkan; kolinlagring; jordbruk; biomassa; biobränslen.; Earth and Environmental Sciences;

    Abstract : Incorporating a multi-year grass ley into an arable crop rotation can increase soil organic carbon stocks, reduce carbon emissions and provide feedstock for biogas. This thesis set out to study how a policy promoting agricultural biomass for biogas impacts GHG emissions and carbon sequestration on a regional level over a temporal scale of 20 years. READ MORE
