1. 1. IMPLICATION FOR THE UNIVERSITY OF GOTHENBURG TO ALIGN WITH THE GOVERNMENT’S TARGET REGARDING CLIMATE NEUTRALITY BY 2045 - Scenarios and Consequences

   University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

   Author : Nafiseh Kazemi Ashtiani; [2023-06-21]
   Keywords : Climate Neutrality; GHG emissions; higher education institutions HEIs ; Net Zero emission; carbon footprint; carbon capture and storage CCS ;

   Abstract : It is widely acknowledged that one of the most significant global challenges of the 21 st century is climate change. In its Fifth Assessment Report (2014), the Intergovernmental Panel on Climate Change (IPCC) described the present extent of the problem and the hazards involved, citing greenhouse gas emissions from human activities as the primary contributor to global warming since the mid-20th century.

4. 3. Major Component Replacement on Floating Wind Turbines

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

   Author : Kilian Galle; [2023]
   Keywords : ;

   Abstract : Among the challenges that floating offshore wind (FOW) energy faces today, operation and maintenanc ecosts, and especially major component replacements (MCR), are an important cost reduction lever. MCRs are defined as any failure on a wind turbine requiring the change of an entire main component of the turbine, such as a gearbox, generator, blade, nacelle, etc. READ MORE

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

   University essay from Lunds universitet/Centrum för analys och syntes

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

   Abstract : 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.
