Europe’s green hydrogen surge: 2025 set to triple growth

With over 60 projects under construction and nearly 200GW of capacity announced, the continent is gearing up for significant growth in green hydrogen. Much of this momentum is powered by early-stage developments, with large-scale projects exploring links to offshore wind and solar-plus-storage systems.

A trio of major installations, including RWE’s GET H2 Nukleus site in Germany, are set to drive nearly half of Europe’s new capacity in 2025. While fewer projects are expected than in 2024, the average project size is climbing, reflecting growing confidence and support, especially from EU funding frameworks.

Alkaline electrolysis remains the backbone technology, favoured for its lower costs, while PEM (proton exchange membrane) electrolysers are making inroads, particularly on smaller or high-efficiency projects. Newer technologies such as AEM (Anion Exchange Membrane) and SOEC (Solid Oxide Electrolysis Cell) are also starting to gain traction, backed by European innovation grants and pilot schemes.

Joe Hennessy from PV Tech Research said, “The size and complexity of projects are increasing – and Europe’s hydrogen future is being shaped by both scale and strategy.”

2025 won’t just be a milestone year in numbers, it will help define how green hydrogen takes root across the continent.
