1. 6. Characterisation of Ionic Liquid doped Polybenzimidazole Membranes for Application in High-Temperature Proton Exchange Membrane Fuel Cells

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Adam Jacobsson Trönndal; [2023]
   Keywords : Fuel cells; Phosphoric acid; Polybenzimidazole; PA-PBI; Ionic liquid; IL; High temperature proton exchange membrane fuel cell; HT-PEMFC; Electrochemical impedance spectroscopy; EIS; IL-PBI; Chemical engineering; Technology and Engineering;

   Abstract : In this study four membranes were tested and evaluated against each other for use in high-temperature proton exchange membrane fuel cell (HT-PEMFC) applications. A phosphoric acid (PA) doped polybenzimidazole (PBI) membrane, was used as a reference as the current state-of-the-art. READ MORE

3. 7. Battery Storage as Grid Reinforcement for Peak Power Demands

   University essay from Linköpings universitet/Energisystem

   Author : Jesper Hilleberg; [2023]
   Keywords : Battery Storage; Battery Energy Storage System; Grid Reinforcement; Flexibility; Lithium-ion battery; li-ion battery; Large Scale Grid Storage; BESS; Energy Storage; Peak Power Demand; Batterilagring; Batterilagringsystem; Nätförstärkning; Nätförstärkningsåtgärd; toppeffektlaster; Flexibilitet; Flexibilitetslösning; litiumjonbatteri; li-ion batteri; BESS; energilagring;

   Abstract : An increased amount of intermittent electricity production, more electric vehicles (EV), and an overall electrification of society may all cause a higher variability between the balance of supply and demand on the electric grid. Battery storage has been identified as a solution to the emerging problem asit can be charged during hours of low power demand and then discharged to help meet the power demand during peak loads.

4. 8. Solar cells to counter rising electricity prices : Self-consumption and profitability of solar cells for a SME in price area 2 in Sweden.

   University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

   Author : Johan Bergdahl; [2023]
   Keywords : SME; Solar cells; Gävleborg County; Self-consumption; Matching;

   Abstract : Increases in electricity prices in Sweden during the second half of 2021 have created a great deal of concern among companies in Sweden. Some companies report that they have stopped their production temporarily when electricity prices have been high. READ MORE

5. 9. Experimental Testing of Solar Photovoltaic/Thermal Collectors for Low Temperature Heat Pump Integration

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

   Author : Jaakko Eskola; [2023]
   Keywords : Solar photovoltaic thermal; PVT; heat pump; thermal performance; ISO 9806:2017; Solhybrid; PVT; värmepump; termisk prestanda; ISO 9806:2017;

   Abstract : A hybrid photovoltaic/thermal (PVT) collector enables simultaneous electricity and heat production from a single solar module. Integrating PVT collectors with a ground source heat pump (GSHP) improves the seasonal performance of the heating system and prevents from temperature degradation of the ground. READ MORE

6. 10. Lowering energy need and improving indoor climate - A case study of rural dwellings in Gammalsvenskby, Ukraine

   University essay from Lunds universitet/Institutionen för arkitektur och byggd miljö; Lunds universitet/Avdelningen för Energi och byggnadsdesign

   Author : Viktor Kauranen; [2022]
   Keywords : Gammalsvenskby; energy-efficient; indoor climate; rural buildings; renovation; Ukraine; Life cycle cost; Technology and Engineering;

   Abstract : A vast majority of rural dwellings in Ukraine are inefficient from an energy perspective, with a major need for energy-efficient renovations. A lot of these buildings are also having problems with the indoor climate, with poor ventilation combined with indoor combustion of fuel which can cause negative health effects. READ MORE
