Electrolysers for the hydrogen revolution: challenges, dependencies, and solutions

Abstract

Due to Europe's gas crisis and the Russian invasion of Ukraine, ramping up the hydro­gen market has become more urgent than ever for European and German policymakers. However, ambitious targets for green hydrogen present an enormous challenge for the European Union (EU) and its young hydrogen economy. Apart from the demand for electricity, there is above all a lack of production capacities for electrolysers. The envisioned production scaling of electrolysers is almost impossible to achieve, and it also conflicts with import efforts and cements new dependencies on suppliers of key raw materials and critical components. Although a decoupling from Russia’s raw ma­terial supply is generally possible, there is no way for the EU to achieve its goals with­out China. Aside from loosened regulations and the active management of raw material supply, Europe should also reconsider its biased preference for green hydrogen. (author's abstract)
