EC considers nuclear a low-carbon source of hydrogen

The European Commission will consider hydrogen produced from nuclear power as "low-carbon", Paula Abreu Marques, head of unit for renewables and CCS policy at the European Commission's energy directorate told the European Parliament on 16 November.

On 8 July, the European Commission adopted the EU Hydrogen Strategy, which sets out how hydrogen can support the decarbonisation of industry, transport, power generation and buildings. The strategy addresses the investments, regulation, market creation, and research and innovation required to enable this.

The strategy says that between 2020 and 2024 the European Commission will support the installation of at least 6 GW of renewable hydrogen electrolysers in the EU, and the production of up to 1 million tonnes of renewable hydrogen. From 2025 to 2030, there needs to be at least 40 GW of renewable hydrogen electrolysers and the production of up to 10 million tonnes of renewable hydrogen in the EU. From 2030 to 2050, renewable hydrogen technologies should reach maturity and be deployed at large scale across all hard-to-decarbonise sectors, it says.

"Hydrogen can power sectors that are not suitable for electrification and provide storage to balance variable renewable energy flows, but this can only be achieved with coordinated action between the public and private sector, at EU level," the Commission said. "The priority is to develop renewable hydrogen, produced using mainly wind and solar energy. However, in the short and medium term other forms of low-carbon hydrogen are needed to rapidly reduce emissions and support the development of a viable market," it added.

The strategy defines 'renewable hydrogen' as "hydrogen produced through the electrolysis of water (in an electrolyser, powered by electricity), and with the electricity stemming from renewable sources. It says 'low-carbon hydrogen' "encompasses fossil-based hydrogen with carbon capture and electricity-based hydrogen, with significantly reduced full life-cycle greenhouse gas emissions compared to existing hydrogen production." The strategy, however, did not specifically mention nuclear power among low-carbon electricity sources.

The European Commission wants hydrogen to be complementary to a renewables-based energy system with renewable electricity at its core, Marques told the European Parliament's committee on environment, public health and food safety.

"Electrolysis can be powered by renewable electricity, which would then be classified as renewable hydrogen," she said. "If you have electrolysers connected to nuclear power stations, this would be classified as low-carbon hydrogen."

"I'm surprised that hydrogen from nuclear energy is not mentioned [in the strategy]," French MEP Joëlle Mélin was quoted as saying by Euractiv. "Renewables won't be enough. I think that we need to go further in defining clean hydrogen."
