  1. 1. Greenhouse gas emissions from peat soil thawing in spring : a comparison between fertilized and unfertilized soil

    University essay from SLU/Dept. of Soil and Environment

    Author : Fanny Otterlin Karlsson; [2024]
    Keywords : agricultural soil; carbon dioxide; freeze-thaw cycles; nitrous oxide; soil temperature; water content;

    Abstract : Peat soils drained for agriculture and forestry contribute to a significant amount of greenhouse gas emissions. Nitrous oxide is a greenhouse gas with high warming potential and agriculture in general accounts for about 70 % of nitrous oxide emissions. READ MORE

  3. 2. The Operational Strategy Optimization of Distributed Energy System Based on MATLAB : A case study in Northeast China

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Yujun Han; [2023]
    Keywords : Distributed Energy System; CCHP; operational strategy; Distribuerat energisystem; CCHP; operativ strategi;

    Abstract : China is the largest energy consumer worldwide, with a fast-growing rate. But the energy and environmental problems brought by its unbalanced energy structure and low energy efficiency restrict the sustainable development of China. The Distributed Energy System (DES) is one of the internationally recognized solutions to the problems. READ MORE

  4. 3. Utilization of Biomethane in Decarbonising India´s Energy Mix

    University essay from KTH/Energiteknik

    Author : Niraj Ravindra Kunkulol; [2023]
    Keywords : Anaerobic digestion; biogas; biomethane; membrane filtration; pressure swing adsorption; Anaerob rötning; biogas; biometan; membranfiltrering; trycksvängadsorption;

    Abstract : This thesis investigates the potential of biomethane production in India, the impact of its integration into the energy mix, and the corresponding Greenhouse Gases (GHG) emission and potential reduction. India, with its huge population and being an agriculturally rich country, produces gigantic amounts of biodegradable waste from various sources such as Municipal Solid Waste (MSW),agricultural waste, animal husbandry, sugar industry, etc. READ MORE

  5. 4. Benchmarking a 1 kW hybrid hydrogen fuel cell system

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Jonathan Envall; [2023]
    Keywords : PEMFC; fuel cell; UAV; hybrid; Technology and Engineering;

    Abstract : Unmanned Aerial Vehicles (UAV's) offer great versatility in the tasks that they may perform and they are today used in many sectors. The H24LEO project, administered by the Lund University School of Aviation, aims to develop and demonstrate a hybrid proton-exchange membrane fuel cell-powered UAV to aid in search and rescue operations performed by the Swedish Maritime Administration, and reduce the greenhouse gas emissions compared to similar work performed by helicopters.

  6. 5. Pathway for Sustainable Aviation : Analysis of Science-Based Targets for Aviation

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

    Author : Sebastian Lindfors; [2023]
    Keywords : Aviation; Airline; Science-Based Targets initiative; Climate change; Sustainable transformation; Alternative fuels; Sustainable aviation fuels SAF ; Hydrogen; Electric aviation; Scenario analysis; Flygindustrin; Flygbolag; Science-Based Targets-initiativet; Klimatförändring; Hållbar transformation; Alternativa bränslen; Hållbart flygbränsle; Väte; Elektrisk flygning; Scenarioanalys 437 07-21;

    Abstract : In order for the aviation industry to meet the targets of the Paris agreement and reach net-zero by 2050, significant amounts of greenhouse-gas emissions are to be reduced. However, as the industry is essentially dependent on conventional jet fuel, it becomes necessary for alternative technologies to develop and phase out fossil-based fuels. READ MORE
