1. Natura 2000-områdens roll i omprövningen av vattenkraftens miljötillstånd
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Miljö- och energisystemSammanfattning : Vattenkraften utgör ungefär 45 % av Sveriges elproduktion och har varit en stabil energikälla med lågt koldioxidutsläpp under lång tid. Med ett allt större inslag av intermittenta energislag i elsystemet, fyller vattenkraften också en viktig funktion med sin reglerförmåga för balansering. LÄS MER
2. Evaluating the accuracy of NEWA, ERA5 and NORA3 in predicting onshore wind conditions: a comparative study using ICOS meteorological mast data in Sweden
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The ECMWF Reanalysis v5 (ERA5), the New European Wind Atlas (NEWA), and the 3 km Norwegian Reanalysis (NORA3) are reference datasets that are available for industry and research. The resolution of 3km in both the NORA3 and NEWA datasets sets them apart, while ERA5, with its 31km resolution, continues to serve as a reliable data source that is widely used in the industry.

3. Navigating Sustainability : A case study exploring alternative energy sources for maritime shipping
Master-uppsats, KTH/Industriell ekonomi och organisation (Inst.)Sammanfattning : This master thesis studies alternative energy sources for maritime shipping in Sweden. With current climate goals, and a need for change, the maritime sector currently undergoes intense transitions. For shipping companies to lower their carbon footprint, the need to replace non decarbonised fuels is hence critical. LÄS MER
4. Exploring potential E-fuel production pathways for maritime and aviation sectors in France : a techno-economic and environmental assessment
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : The aviation and maritime industries pose significant challenges for decarbonization, having increased activity in the past decade. One promising solution to limit emissions in these sectors is Electrofuels (E-fuel), derived from water electrolysis hydrogen and captured CO2 or nitrogen. LÄS MER
5. Impact of nitrogen availability and nitrogen structural composition on fungal enzymatic activity and growth : how nutrient availability governs response and development of three saprotrophic Basidiomycetes
Master-uppsats, SLU/Dept. of Soil and EnvironmentSammanfattning : Fungi excrete a wide variety of extracellular enzymes to scavenge for nutrients, such as the often scarce yet essential nutrient nitrogen. All fungi produce highly specialized hydrolytic enzymes, e.g. peptidases, that depolymerize organic molecules. LÄS MER
