1. 1. Integrating Waste Heat from Hydrogen Production Into District Heating

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Fawzi Kayali; [2023]
   Keywords : Hydrogen; Electrolysis; Waste Heat Recovery; Combined Heat and Power Plant; District Heating; Simulation; Sustainable Heating Systems; Technology and Engineering;

   Abstract : The aim of this research is to explore the feasibility of the integration of waste heat from electrolyzers within a Combined Heat and Power (CHP) plant and district heating (DH) network and suggest a practical setup for integration. With the escalating emphasis on the development of green hydrogen through electrolysis powered by renewable energy, a substantial amount of waste heat is generated, typically left unused. READ MORE

3. 2. Unlocking the Potential of Solar-Hydro Hybrid Solutions: Feasibility and Economic Analysis

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : Måns Rosberg; [2023]
   Keywords : Hydropower; Solarpower; Hybrid power production; Solar-hydro hybrid power; Reservoir storage; Energy storage; Pumped hydro power; Floating PV; PV; Photovoltaics; Technology and Engineering;

   Abstract : Hybrid solutions that combine multiple renewable energy sources, such as solar power and hydro power, are gaining popularity as a means of meeting the growing energy demands while minimising environmental impacts, but also as an opportunity of connecting solar power plants to the grid in areas where this might not be possible unless large investments are made. This master thesis aims to evaluate the feasibility and economic viability of integrating solar panels with an existing grid connection point at a hydro power plant, along with the introduction of an energy storage solution using a hydro power plant reservoir.

   Keywords : Heating; Ventilation; Free cooling; Borehole; Ground source heat pump; Compact unit; Solar thermal collector; District heating; Underfloor heating; Radiators; Convectors; Thermal energy storage; Norway; Sweden; Finland.; Technology and Engineering;

   Abstract : To meet the aims of the Paris climate agreement, it is necessary to reduce energy use in buildings. Efficient HVAC systems are a critical part in achieving a low delivered energy use. READ MORE

5. 4. ManagementPractical Aspects of Aqua Ammonia as Secondary Refrigerant in Ice Rinks

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

   Author : Jacqueline Pierri; [2021]
   Keywords : Ice rink; secondary refrigerant; refrigeration; refrigerant management; secondary fluid; natural refrigerant; aqua ammonia;

   Abstract : The transition from fluorinated gases to natural refrigerants could be key to reducing the impacts of climate change. Ice rinks are energy-intensive buildings, with large heating and cooling demands. The pumping power required to move the secondary refrigerant typically accounts for a sizable amount of the energy use of the refrigeration system. READ MORE

6. 5. Internal strain in the magnetocaloric alloy MnCoSi

   University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Author : Olivia Vaerst; [2021]
   Keywords : MnCoSi; Magnetocaloric Effect; Arc Melting; Strain; X-Ray Diffraction; Williamson-Hall; Rietveld Refinement; Physics and Astronomy;

   Abstract : Cooling systems based on magnetic refrigeration are a promising and environmentally friendly alternative to commonly used gas-compression refrigeration. Magnetic refrigeration is based on the magnetocaloric effect. READ MORE
