EU’s green hydrogen goals could gobble up 30% of all European renewables supply by 2030: report
Non-profit warns that electrolysers producing ten million tonnes of H2 per year would need more electricity than Germany

REPowerEU is also targeting 592GW of solar capacity (up from around 209GW in 2022) and 510GW of wind power (up from around 255GW in 2022) by 2030, producing around 1,962TWh per year — which RGI said would be enough to sustain both green hydrogen production and the EU’s target of achieving 69% of renewable penetration in its power supply by 2030.
“The prioritisation of hydrogen production over direct electrification means Europe will have to use significant amounts of electricity based on wind and solar in an inefficient way, which will generate energy losses and will not serve to optimise the system,” the report says.
This means that electricity will be consumed in making green hydrogen — which has 60-90% efficiency depending on the electrolysis technology — rather than running directly to the customer, meaning that Europeans would pay more for less.
“[It] seriously questions the ‘energy efficiency first’ principle, as this additional renewable energy capacity could feed more electric vehicles instead of using hydrogen for transport, and heat pumps, instead of blending [into fossil-gas networks] outlined in REPowerEU,” the non-profit explains.
RGI, which includes 13 power grid transmission system operators and 15 environmental NGOs among its members and is partly funded by the EU and the German government, singled out the use of hydrogen in transport and blending as a particularly egregious use of Europe’s renewable resources.
“Directing additional renewables proposed by REPowerEU towards more efficient electrification options for transport and heating would contribute to significant savings and system optimisation,” it says. “This is especially true for hydrogen intended for the transport sector (excluding synthetic fuels) and blending (for heating), which in REPowerEU accounts for 3.6 million tonnes [of green hydrogen].”
