Potential and risks of hydrogen-based e-fuels in climate change mitigation

Falko Ueckerdt starts with structuring the current hydrogen debate (in particular in Germany and the EU). Then he goes through key techno-economic aspects that determine the role of hydrogen-based e-fuels, particularly compared to a direct electrification. This includes green hydrogen electrolysis expansion (available quantities), energy efficiencies, climate mitigation effectiveness, as well as direct and abatement costs. Falko briefly discusses blue hydrogen and other options of bridging the low mid-term availability of green hydrogen. In his conclusions he argues that societies' hydrogen expectations should be focused on no-regret sectors. Broadly betting on (future) hydrogen, while neglecting available direct electrification technologies (and domestic renewable expansion), risks further fossil fuel dependence (new lock-ins).
