Green Hydrogen in Europe: Who Stands to Benefit From Nuclear?

Why It Matters

Allowing nuclear in green‑hydrogen production would unlock a larger, more reliable low‑carbon power base, accelerating the EU’s climate targets and reducing import dependence. It also creates a competitive advantage for nations with existing nuclear fleets.

Key Takeaways

• EU's AccelerateEU may add nuclear to green hydrogen eligibility
• RFNBO certification currently requires 90% renewable grid share or direct renewable supply
• France, Finland, Sweden could meet 90% threshold with nuclear counted
• Spain, Germany have biggest hydrogen pipelines but only ~60% renewables
• Nuclear inclusion could ease project financing and grid constraints

Pulse Analysis

AccelerateEU reflects the EU’s urgency to diversify its energy mix amid geopolitical tensions and the looming need to meet the Renewable Energy Directive’s 2030 targets. Green hydrogen, classified as a Renewable Fuel of Non‑Biological Origin, has become a cornerstone of the bloc’s decarbonisation strategy, yet its growth is throttled by strict RFNBO rules that demand a near‑pure renewable electricity supply. By revisiting the definition of eligible power sources, policymakers are signaling a willingness to broaden the low‑carbon portfolio beyond wind and solar, potentially reshaping investment pipelines across the continent.

Nuclear power, long debated for its carbon‑free credentials, could serve as a bridge for countries with mature reactor fleets. France, home to the world’s largest nuclear capacity, along with Finland and Sweden, would instantly satisfy the 90% renewable‑grid benchmark if nuclear were counted, giving them a head‑start in securing RFNBO certification. This advantage may attract developers to locate electrolyser sites near existing plants, leveraging excess baseload capacity and reducing the need for costly renewable build‑outs. Conversely, nations like Spain and Germany, which host the most ambitious hydrogen project pipelines, would still need to boost renewable generation or procure additional clean power to meet the threshold, potentially slowing project timelines.

The inclusion of nuclear raises several strategic considerations. Regulators must define clear criteria for counting nuclear output, address public concerns about safety and waste, and ensure that any new builds align with the EU’s long‑term decarbonisation roadmap. From an investment perspective, the policy could lower financing costs for hydrogen projects by mitigating supply‑risk premiums, while also revitalising the nuclear supply chain. Ultimately, the decision will influence the geographic distribution of Europe’s green‑hydrogen hubs, the pace of infrastructure rollout, and the bloc’s ability to meet its climate commitments without over‑relying on imported fuels.
