Building on the successful work of the Clean Hydrogen Partnership with regions and on the learnings of the BIG-HIT project supported under the Call for Proposals 2015 of the Clean Hydrogen Partnership, support to Hydrogen Valleys has been included in all JU Call for Proposals since 2019. Against this backdrop, projects such as HEAVENN (Call 2019) and Green Hysland (Call 2020) have become pioneers and flagships of the Hydrogen Valley concept.
Building on the above activities, Hydrogen Valleys have been identified in the RePowerEU plan as a essential in order to scale up Europe’s hydrogen economy. This is the case because they bring together clean hydrogen production, storage of hydrogen and distribution to end-uses while creating regional value chains. Against this backdrop, the European Commission’s inspirational target is to have at least 50 Hydrogen Valleys under construction or operational by 2030 across the entire EU1.
Acknowledging the role of the Clean Hydrogen JU in initiating the concept of Hydrogen Valleys and of its initial support, the European Commission allocated to the Clean Hydrogen Partnership an additional €200 million through RePowerEU, to double the number of Hydrogen Valleys in Europe by 2025.
Altogether, the Clean Hydrogen JU has supported to date 24 hydrogen valleys projects across 21 European countries, out of which 23 projects are still ongoing. Together they represent project costs for more than €1.5 billion, with total JU funding of more than €300 million.
A list of the hydrogen valleys supported by the Clean Hydrogen Partnership to date can be found below.

2 HEAVENN is supported under the Call 2019; the Call requirement was to produce and consume at least 1500 tonnes/year of H2
3 BIG-HIT was supported under the Call 2015; at the time referred to as a Hydrogen Territory, there were no minimum requirements in the Call for the levels of hydrogen production / consumption
4 GreenHysland is supported under the Call 2020; the Call requirement was to produce and consume at least 300 tonnes/year of H2
Latest events
The Clean Hydrogen Partnership is pleased to announce that the third edition of the Hydrogen Valleys Days will take place on 4–8 May 2026 at the Port House (Port of Antwerp-Bruges), in Antwerp.
Join us at 'Hydrogen Valleys: Driving Europe’s Competitiveness' on 24-25 June 2025 in Brussels. Engage with industry leaders, explore pioneering hydrogen projects, and discover opportunities for growth, innovation, and collaboration. Be part of shaping Europe's clean energy future!
The event, co-organised by the Clean Hydrogen Partnership and the European Commission - DG Research and Innovation, will take place in Brussels on 17-18 June 2024, at the Hotel, and builds on the successful work of the Clean Hydrogen JU with European regions and cities, including project development assistance and funding of 15 hydrogen valleys across Europe. This groundwork sets the stage for the launch of an EU roadmap for Hydrogen Valleys and related facility.
Based on extensive collection of primary data from the projects, the platform provides comprehensive insights into the most advanced and ambitious Hydrogen Valleys around the globe.
The purpose of this two-day workshop was for the regional and local actors to talk about current opportunities and challenges in rolling-out and scaling-up Hydrogen Valleys in Europe. The workshop was by invitation only and targeted stakeholders of existing and future hydrogen valleys.
