Hydrogen in the Reformed EU ETS

Figure: Comparing green (left) and blue hydrogen (right) costs accounting for EU ETS impacts (assumed CO2 price: 80 โฌ/tCO2) based on the optimistic end of near-term cost estimates for 2025 to 2030. The value of free allocations is calculated based on CBAM factor of 100 %, which applies until the end of 2025. No additional subsidies considered here.
Hydrogen in the Reformed EU ETS: What It Means for Competitiveness and Emissions Reductions?
๐น Key insights:
๐ The EU ETS alone cannot make hydrogen competitive.
- Hydrogen production (both renewable and blue) remains significantly more expensive than natural gas โ currently 4 to 6 times more costly.
- The value of freely allocated ETS allowances does little to close this gap, as illustrated in the picture below with the green part, especially with today’s relatively low COโ prices.
๐ To bridge the cost gap and enable a fuel switch from natural gas to low-carbon or renewable hydrogen, COโ prices of โฌ300โ500/tCOโ would be necessary.
๐ Switching from blue to green hydrogen would require โฌ2500/tCOโ if only downstream emissions are priced.
โ
Policy recommendations include:
๐ Expanding the EU ETS to cover upstream emissions for a more accurate climate cost signal.
๐ Gradually lowering the emission intensity threshold (currently 28.2 gCOโeq/MJ) for low-carbon hydrogen to encourage innovation and deeper decarbonisation.
๐ก To use hydrogen for the energy transition, it is essential to go beyond emissions pricing and rethink how to support its competitiveness and climate impact.
