1. 1. 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.

3. 2. Comprehensive Study of Meta-heuristic Algorithms for Optimal Sizing of BESS in Multi-energy syste

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

   Author : Joakim Ginste; [2022]
   Keywords : BESS; Energy arbitrage; Firefly algorithm; Genetic algorithm; Peak shaving; BESS; energiarbitrage; Firefly algorithm; Genetic algorithm; spetslastutjämning;

   Abstract : The question of finding the optimal size for battery energy storage systems (BESS) to be used for energy arbitrage and peak shaving has gained more and more interest in recent years. This is due to the increase in variability of electricity prices caused by the increase of renewable but also variable electricity production units in the electricity grid. READ MORE

4. 3. Integration of Photovoltaic Thermal Technology in the Greenhouses (A case study of Greece and Portugal)

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Syed Aman Shah; [2022]
   Keywords : Renewable energy; photovoltaic; photovoltaic thermal; solar thermal; PV; PVT; crops plantation under greenhouses; greenhouses; climate change; and arable lands.;

   Abstract : The thesis work was done as a part of the company's proposal writing work for the Horizon Europe projects, which is the European Union's key funding program for research and innovation with a budget of €95.5 billion. READ MORE

5. 4. Optimization of a decentralized energy system by implementing three different storage solutions for a small residential district in Ludvika, Sweden

   University essay from Högskolan Dalarna/Institutionen för information och teknik

   Author : Mathieu Tayarani; [2022]
   Keywords : Energy storage; stationary batteries; hydrogen storage; residential energy system; energy optimization;

   Abstract : The acceleration towards achieving a low carbon society has raised many challenges in the energy sector. The existing systems, highly dependent on fossil fuels, are not sustainable and recommendations are made to accelerate the transition by using more renewable and low-carbon sources of energy.

6. 5. Smart charging of an electric bus fleet

   University essay from Uppsala universitet/Elektricitetslära

   Author : Emil Färm; [2021]
   Keywords : Smart charging; Electric vehicle; EV; Electric buses; Bus depot; Electrification; Frequency regulation; FCR; Load balancing; Electrical power systems; Smart laddning; Elfordon; EV; Elbussar; Bussdepå; Elektrifiering; Frekvensreglering; FCR; Lastbalansering; Elektriska system; Elnät;

   Abstract : Controlling the balance of production and consumption of electricity will become increasingly challenging as the transport sector gradually converts to electric vehicles along with a growing share of wind power in the Swedish electric power system. This puts greater demand on resources that maintain the balance to ensure stable grid operation. READ MORE
