1. 1. Techno-economic analysis of commercial battery storage systems in Northern Europe

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

   Författare :Albert Bergström; [2020]
   Nyckelord :;

   Sammanfattning : As the world looks to lower its need for fossil fuels, photovoltaics has been put forward as one of the proposed solutions. There is, however, one major drawback with the electricity production coming from photovoltaics – it is intermittent and rarely matches the electricity demand profile of society. LÄS MER

3. 2. Temperature and concentration dependence of hydrogen diffusion in vanadium measured by optical transmission

   Kandidat-uppsats, Uppsala universitet/Materialfysik

   Författare :Stefan Book; [2014]
   Nyckelord :Hydrogen diffusion; Vanadium; Metal hydride; Hydrogen storage; Hydrogen economy;

   Sammanfattning : Hydrogen diffusion is investigated in a 50 nm film of vanadium and a vanadium superlattice. Diffusion constants for three different temperature and pressure pairs are determined for the 50 nm film. The diffusion constants for the temperature and pressure pairs are determined to be 4.5 $\pm$ 0. LÄS MER
