Little to Lose: The Case for a Robust European Green Hydrogen Strategy

The EU targets 10 Mt of green hydrogen production by 2030 but has not committed to targets for 2040. Green hydrogen competes with carbon capture and storage, biomass, and imports as well as direct electrification in reaching emissions reductions; earlier studies have demonstrated the great uncertainty in future costoptimal development of green hydrogen. In spite of this, we show that Europe risks little by setting green hydrogen production targets at around 25 Mt by 2040. Employing an extensive scenario analysis combined with novel near-optimal techniques, we find that this target results in systems that are within 10% of cost-optimal in all considered scenarios with current-day biomass availability and baseline transportation electrification. Setting concrete targets is important in order to resolve significant uncertainty that hampers investments. Targeting green hydrogen reduces the dependence on carbon capture and storage and green fuel imports, making for a more robust European climate strategy.
