1. 21. Klimateffekterna av elektrobränsle för flyg

   University essay from SLU/Dept. of Energy and Technology

   Author : Jonatan Persson; [2023]
   Keywords : Livscykelanalys LCA ; växthusgaser; klimatförändringar; Carbon Capture and Utilization CCU ; flygindustrin; utsläppsminskningar; HySkies;

   Abstract : Kan elektrobränsle vara den nyckeln som flygindustrin behöver för att bekämpa klimatförändringarna? Detta arbete handlar om att utföra en livscykelanalys av elektrobränsle för att bedöma dess effektivitet som en hållbar lösning för att minska klimatpåverkan från flygindustrin. Elektrobränsle är en variant av hållbart flygbränsle, SAF (Sustainable Aviation Fuel). READ MORE

3. 22. How is carbon stored in boreal forest soils? - A method development which investigates at what protein concentration ferrihydrite and goethite are saturated.

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

   Author : Louise Berild; [2023]
   Keywords : Soil nitrogen; soil carbon; boreal forest; ectomycorrhizal fungi; decomposition; adsorption; ferrihydrite; goethite; Earth and Environmental Sciences;

   Abstract : Boreal forests store the majority of their carbon in the soil and play an important role in the global carbon cycle. However, the mechanisms that control carbon storage in boreal soils are not well understood. READ MORE

4. 23. Assessing the EnvironmentalPerformance of an In-Store VerticalFarming System : Identifying environmental hotspots for an in-store hydroponic vertical farmingsystem, using Life Cycle Assessment

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Axel Karlsson; [2023]
   Keywords : Vertical Farming”; “Life Cycle Assessment; Sweden; Environmental impacts; industrial symbiosis; Urban farming; Vertical Farming; Livscykelanalys; Sverige; Miljöpåverkan; Industriell symbios; Stadsodling;

   Abstract : The world is facing many challenges to be able to ensure food security, such as anincreased food demand coming from an expanding world population andurbanisation, worsened agricultural opportunities from increased land deteriorationand significant environmental impacts coming from the food sector. Thus, there is aneed for new agricultural solutions to meet our needs whilst decreasing impactssimultaneously. READ MORE

5. 24. Applying LPJ-GUESS on the Arctic: A model evaluation and benchmarking study

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Margot Jeanne Knapen; [2023]
   Keywords : Physical Geography and Ecosystem Analysis; LPJ-GUESS; Arctic; FLUXNET; Gross Primary Productivity; Ecosystem Respiration; Permafrost; Active Layer Thickness; Snow Depth; Earth and Environmental Sciences;

   Abstract : Warming in the Arctic occurs at a much higher rate than the global average, which has a considerable impact on the Arctic terrestrial carbon cycle. Permafrost thawing can release substantial amounts of carbon, whilst tundra shrubification and tree-line advance, on the other hand, may compensate for this. READ MORE

6. 25. Lifecycle Assessment of a Lithium-ion Battery Storage System for Frequency Regulation in a Real-World Application

   University essay from

   Author : Samuel Sulemanu; [2023]
   Keywords : Frequency Containment Reserve - Disturbance FCR-D ; Frequency Regulation; Life Cycle Assessment LCA ; Lithium-ion Battery; Simapro; Renewable Energy; Solar PV; Wind; Energy; Climate Change;

   Abstract : Integrating more renewable energy sources into the grid has caused increased instability due to the intermittency of renewable energy sources. Hence, the need for grid balancing strategies such as frequency regulation has intensified. READ MORE
