1. 26. Greenhouse gas emissions and energy efficiency of various renewable energy pathways in the truck industry : An LCA and energy efficiency analysis on fuel production for and manufacturing of 40 tonne heavy trucks in Sweden

   Master-uppsats, Linköpings universitet/Institutionen för tema; Linköpings universitet/Filosofiska fakulteten

   Författare :Jacob Axell; [2023]
   Nyckelord :Hydrogen; Sweden; 40-tonne haulage truck; LCA; Wind energy; Bio fuel; Energy efficiency; CO2 emissions;

   Sammanfattning : This study focuses on assessing the greenhouse gas emissions and energy efficiency of 40-tonne haulage trucks in fuel production and manufacturing in a Swedish context. The aim was to provide accurate greenhouse gas accounting and evaluate the contribution to mitigating climate change. LÄS MER

3. 27. The EU Taxonomy and the Energy Supply Sector - A qualitative case study on the implications of the EU Taxonomy on the regulatory reporting requirements in the energy supply sector

   Kandidat-uppsats, Lunds universitet/Ekonomisk-historiska institutionen

   Författare :Hannah Beckenbauer; [2023]
   Nyckelord :Business and Economics;

   Sammanfattning : The EU Taxonomy provides a clear set of criteria for identifying sustainable economic activities and facilitating investment flows in alignment with sustainable practices. Although dynamic, the Taxonomy emphasizes the mitigation of greenhouse gas emissions and biodiversity conservation, making it crucial for companies, policymakers, and capital markets. LÄS MER

4. 28. Possibility for Positive Energy Retrofit in Borlänge

   Magister-uppsats, Högskolan Dalarna/Institutionen för information och teknik

   Författare :Daniel Nay Myo Tun; Abideen Olaide Bakare; [2023]
   Nyckelord :;

   Sammanfattning : The built environment accounts for 40% of annual carbon dioxide (C02) emissions. Among the total emissions, building operations generate approximately 27% annually. Other than this, building materials, infrastructural materials, and construction (embodied carbon) contribute to an additional 13% annually [1]. LÄS MER

5. 29. Reprocessing and Characterization of Polybenzimidazole for High-Temperature Polymer Electrolyte Membrane Fuel Cells

   Master-uppsats, Lunds universitet/Centrum för analys och syntes

   Författare :Douglas Björkengren; [2023]
   Nyckelord :polymer electrolyte membrane fuel cells; PEMFC; HTPEMFC; polymer technology; polymer characterization; reprocessing; recycling; polybenzimidazole; PBI; Technology and Engineering;

   Sammanfattning : A reprocessing method of poly(2,2’-(m-phenylene)-5,5’-bibenzimidazole) (PBI) membranes recovered from the production line of High-Temperature Polymer Electrolyte Membrane Fuel Cells (HT-PEMFC) at Blue World Technologies (BWT) has been developed in order to reduce material loss in the production. Redissolution of scrap PBI membranes in poly(phosphoric acid) (PPA) and phosphoric acid (PA) was successful and the subsequent washing procedure produced PBI that could be redissolved in N,N-dimethyl acetamide (DMAc) and suitable for solution casting of new membranes.

7. 30. Synthesis and characterization of lactic acid-based elastomers

   Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Författare :Afsaneh Makhdoumi; [2023]
   Nyckelord :Lactic acid; Elastomer; Bio-based elastomer; Renewable resource;

   Sammanfattning : Synthesized polymer from bio-based and renewable resources reported as an attractive substitution for fossil-fuel based polymers. Therefore, this work has focused on using sustainable material for production of elastomers to reduce the environmental impact of fossil-based elastomers and overcome the shortage of non-renewable fuels.
