Okoljski vplivi pridobivanja vodika z različnimi tehnologijami elektrolizerjev

Cimermančič, Matevž (author), Mori, Mitja (mentor)

Potrebe po energiji naraščajo, hkrati pa ostaja težnja po uporabi zelenih virov energije. Vodikove tehnologije ponujajo številne prednosti in se v tem trenutku zdijo primerna rešitev za zadostitev okoljskih zahtev. V nalogi so pregledane aktualne tehnologije elektrolizerjev, na podlagi katerih so postavljeni numerični modeli za študijo življenjskih ciklov posameznih tehnologij in njihova medsebojna primerjava okoljskih vplivov ob proizvodnji 1 kg vodika z uporabo električne energije iz virov v Sloveniji. Ugotovljeno je bilo, da je faza obratovanja elektrolizerjev bistvenega pomena iz vidika okoljskih vplivov, ter da je izbira vira električne energije odločujoča. Najbolj smiseln vir za napajanje elektrolizerja je hidro energija, medtem ko ni smiselno uporabljati slovenske energijske mešanice.

• Title: Environmental impacts of hydrogen production with different electrolyser technologies

Abstract

The needs for energy are growing, but a tendency to use green energy sources is the same. Hydrogen technologies offer many advantages and so far seem to be a suitable solution to meet environmental requirements. This work examines current technologies of electrolysers, based on which numerical models for life cycle assessment of individual technologies are set up. A mutual comparison between technologies is made regarding production of 1 kg of hydrogen. It was found that the operation phase of electrolysers is the most critical from the point of view of environmental impacts, and that the choice of Slovenian energy source is decisive. The most sensible source to power an electrolyzer is hydro energy, while it does not make sense to use a Slovenian energy mix.
