1. 21. Life cycle assessment on sodium-ion cells for energy storage systems : A cradle-to-gate study including 16 environmental perspectives, focusing on climate change impact

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

   Author : Rebecca Nibelius; [2023]
   Keywords : Sodium-ion batteries; Life cycle assessment; Cradle-to-gate; Natriumbatterier; Livscykelanalys; Vagga-till-port;

   Abstract : Because of the changing energy supply landscape, with the transition towards renewable energy, an emerging demand for energy storage systems (ESS) is expected in the near future. Battery energy storage is promising to contribute to mitigate the greenhouse gas emissions, but face issues considering resource use (IEA, 2023; IRENA, 2022). READ MORE

3. 22. Investigation of new refrigerants for a large-scale heat pump and evaluation of system performance

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Hanna Grahn; Matilda Eriksson; [2023]
   Keywords : Large-scale heat pump; refrigerant; COP;

   Abstract : Heat production accounted in 2021 for 50 % of the energy end use globally, where a strongconnection to fossil sources still exists. Large-scale electrical heat pumps can therefore have akey role in the energy system to enable a decreased reliance on fossil fuels and at the same timecontribute to stable system when incorporating more intermittent renewable sources.
