  1. 21. 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. 22. Small-scale wave energy converter for wave tank facility

    University essay from Uppsala universitet/Elektricitetslära

    Author : Samir Asseh; [2023]
    Keywords : Wave power; small-scale; Wave tank; facility; Renewable resources; damping; froude scaling; magnets; copper coil; Uppsala University; buoy; MATLAB; COMSOL; PTO; WEC; Electricicity generation.; Förnybar energi; Vågtank; Vågkraft;

    Abstract : A small-scale wave energy converter was designed and built for teaching and academic purposes to be used at The Division for Electricity, in the Ångström Laboratory at Uppsala University. The design of the power take-off (PTO) makes use of magnets passing through a copper coil for electricity generation. READ MORE

  4. 23. Using a GIS to enable an economic, land use and energy output comparison between small wind powered turbines and large-scale wind farms: the case of Oslo, Norway.

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Colin Potter; [2023]
    Keywords : Geography; GIS; Wind power; Renewable energy sources; urban wind energy; urban areas; planning; vertical axis wind turbines; comparative studies; urban integrated energy systems; Oslo; Roan; Earth and Environmental Sciences;

    Abstract : Responding to an identified knowledge gap, the study aims to determine if smaller wind turbines located on top of existing urban buildings are more resource efficient (land utilization and economically) than large scale wind farms. To answer this question, using a GIS, the resource efficiency of the Roan wind farm in Northern Norway was compared to a theoretical modeled installation of small-scale wind turbines on top of buildings within a 2km radius study zone in central Oslo.

  5. 24. Solar industrial heating with a hybrid solar collectors’ configuration and thermal storage : Dynamic simulation and techno-economic analysis

    University essay from Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Author : Gisela Subirats Gonzalez; [2023]
    Keywords : Solar thermal; Thermal Energy Storage; TES; PV; Brenmiller; Absolicon.;

    Abstract : This study investigates the feasibility and performance of a hybrid system integrating photovoltaic (PV) and solar thermal technologies for industrial process heat. By analyzing various parameters including cost, income, energy production, and system specifications, valuable insights are obtained. READ MORE

  6. 25. Analysis of Microgrid Electrification on Phaluai Island : A Minor Field Study in Thailand

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

    Author : Leontina Walldén; Caroline Wahlberg; [2023]
    Keywords : Microgrid; Rural electrification; Rural islands; Thailand; Renewable energy; Microgrid; Elektrifiering av landsbygd; Isolerade öar; Thailand; Förnybar energi;

    Abstract : Similar to numerous other nations, Thailand aims to achieve carbon neutrality by 2050 by reducing reliance on fossil fuels and increasing the amount of renewable energy sources in electricity generation. The objective of the Thai Provincial Electricity Authority (PEA) is to ensure electricity access for all Thai households and villages. READ MORE
