European Hydrogen Week 2025: Scaling Innovation Across the Hydrogen Value Chain

European Hydrogen Week 2025 returns to Brussels from 29 September to 3 October, offering the most comprehensive overview of hydrogen innovation, market development, and policy in Europe.

This annual event, now a staple in the clean energy calendar, convenes industry leaders, policymakers, researchers, and investors to exchange on how hydrogen can power Europe’s decarbonisation and competitiveness goals.

Over five days, the agenda includes plenaries, breakout sessions, exhibitions, project spotlights, and networking zones. Whether you are leading a Hydrogen Valley, investing in electrolysers, managing infrastructure, or shaping national hydrogen strategies, this is where decisions get made and partnerships forged.

Hydrogen Week will also showcase EU-funded success stories and give space to startups, SMEs, and pilot projects paving the way for large-scale deployment.

Organised by Hydrogen Europe, the Clean Hydrogen Partnership, and the European Commission, the event brings together the public and private sector to advance Europe’s clean hydrogen strategy—from lab to market.

Key themes include:

• Scaling production and reducing costs of renewable and low-carbon hydrogen
• Building robust infrastructure and storage systems
• Cross-sector integration (transport, industry, energy)
• Policy and regulatory frameworks for sustainable deployment
• International collaboration and hydrogen diplomacy
