Techno-Economical Analysis of Power-to-Hydrogen with Alkaline or PEM Electrolysis: Results of the Study Plan-DelyKaD

摘要

Hydrogen generation by electrolysis is expected to play an important role as a crosslinking technology between power generation on one hand and transport and industry on the other hand. When produced by water electrolysis from renewable energies - such as solar or wind - hydrogen can directly replace fossil fuels in transport and industry, thereby helping in the integration of renewable energies in other energy sectors. The relevant technologies are either the mature alkaline water electrolysis or the newer proton exchange membrane (PEM) water electrolysis, which exhibits higher potentials for performance enhancement and cost reduction.
