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. Optimization of Thermal Comfort on Electric Buses : A Comprehensive Study on Passenger Satisfaction in Stockholm, Sweden

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

   Author : Ellinor Hambraeus; Maxwell Minotta Cuervo; [2023]
   Keywords : Electric bus; Bus temperature; Thermal comfort; Energy efficiency; Predicted Mean Vote; Equivalent temperature v; Elbuss; busstemperatur; termisk komfort; energieffektivisering; Predicted Mean Vote; Ekvivalent temperatur vii;

   Abstract : The transition towards electrification in the bus sector is necessary to achieve the global climate goals and has gained significant traction in recent years. However, there are critical challenges associated with this transition, one of them being the absence of excess heat that traditional combustion engines provided to warm the bus cabin. READ MORE

4. 3. Evaluating the effects of climate change on Arctic char : including impacts of brown trout competition

   University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

   Author : Ola Carlström; [2023]
   Keywords : arctic char; brown trout; climate change; diet; habitat use; temperature;

   Abstract : Climate change is predicted to increase the average global temperature with 1.5 °C between 2030 and 2052. The areas that are most vulnerable for climate change are the arctic regions. Arctic char (Salvelinus alpinus) is a cold-water salmonid species with the most northern distribution of all freshwater fish species. READ MORE

5. 4. Heating system performance and thermal mass evaluation of a former military building in mid-Sweden

   University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

   Author : Javier Ruiz Pacheco; [2023]
   Keywords : Thermal mass; District Heating; IDA-ICE; Sweden; C02 emissions;

   Abstract : The concern about global warming is gaining momentum. So, many initiatives, such as the Green European pact, which aims to reach to zero greenhouses emissions in 2050, are emerging to halt it. READ MORE

6. 5. Global Warming Induced by Oceanic Anoxic Event 1a Had a Pronounced Impact on the Early Cretaceous Terrestrial Vegetation of Southern Sweden

   University essay from Uppsala universitet/Paleobiologi

   Author : Marcos Amores; [2022]
   Keywords : palynology; spore-pollen; biostratigraphy; oceanic anoxic event 1a; high-latitude; Early Cretaceous;

   Abstract : The Mesozoic is punctuated by several rapid global warming events that are marked by the worldwide deposition of organic-rich marine sediments. These events, known as oceanic anoxic events (OAEs), are characterised by intervals where the worldwide carbon cycle suffers a disruption due to major palaeoceanographic and climatic shifts, leading to anoxic marine environments and the creation of black shales.
