3. 7. Bitcoin Mining in Sweden

   University essay from Lunds universitet/Miljö- och energisystem

   Author : Sixten Hager; [2022]
   Keywords : ASIC; Bitcoin; Bitcoin mining; proof-of-work; blockchain; district heating; heat recovery; climate change; Sweden; Technology and Engineering;

   Abstract : Bitcoin mining is an industry which for many years has been criticized for its electricity consumption, which globally today equals roughly that of small countries such as Sweden, and its subsequent contribution to climate change. However, electricity consumption does not by default equals greenhouse gas (GHG) emissions and not many studies have been done on the subject with a focus on Sweden, hence this study aims to provide some clarity to the otherwise opaque space of Bitcoin mining.

4. 8. Heat Export from Supermarkets : Refrigeration Systems Field Measurements and a Techno-economic Analysis

   University essay from KTH/Energiteknik

   Author : Julia Linnea Hildur Almebäck; Rebecka Magnius; [2022]
   Keywords : Heat Recovery; Heat Export; Supermarkets; Refrigeration Systems; CO2 Transcritical Booster Systems; Energy Efficiency; Värmeåtervinning; värmeexport; livsmedelsbutiker; kylsystem; CO2 transkritiskt boostersystem; energieffektivitet;

   Abstract : Supermarkets have a high energy demand where almost half of the energy is used within the refrigeration system. The refrigeration system utilises a cycle where heat is taken and rejected. The rejected heat could be recovered and utilised for other purposes, such as covering internal heating demand or be exported to other facilities. READ MORE
