CLEANHYPRO: The journey continues with open calls and new resources
CLEANHYPRO is establishing a European open innovation test bed focused on advancing circular innovative materials, components and stacks for electrolysis.

Several months into the CLEANHYPRO journey, some key updates are topical as we transition from planning into our crucial implementation phase.
The clean hydrogen sector is at a pivotal moment: the technology is ready, but high costs and a lack of accessible, large-scale testing infrastructure remain major barriers to widespread adoption.
CLEANHYPRO is dedicated to meeting this challenge by establishing this first open innovation test bed. The fundamental goal is simple: to provide a single entry point, where industrial partners, especially innovative SMEs, can access the expertise and equipment they need.
This network of technical and business support minimises the typical costs and risks associated with scaling revolutionary electrolysis technologies. This collaborative model is essential to ensure Europe maintains its competitive edge in the global hydrogen race.
Methodology and project progress
The open innovation test bed model is built on two core pillars: technical infrastructure, and collaboration and knowledge dissemination.
On the technical front, the integration of nine pilot lines has been finalised. These advanced manufacturing and testing facilities cover all major electrolysis technologies (AEL, PEM, AEM, SOEC) and are designed to validate materials and components up to TRL7. The consortium, comprising 28 leading research and industrial partners, ensures that services cover the entire development cycle, from initial material design and modelling to final component testing and certification.
Beyond testing, we are working to broaden public understanding and support our applicants. The recently launched Hydra's Academy is a new educational initiative designed to simplify the clean hydrogen transition. This campaign is aimed to introduce our key terms to the general public and provide a space to learn the basics about these subjects.
This learning hub provides concise content on the basics of hydrogen, electrolysis and the mechanisms of the open innovation test bed and single entry point. We invite you to visit our website to watch the educational videos and download the infographics to make these complex technologies more accessible.
Open calls: Opportunities for innovation
A significant milestone in the project has been the launch of the first wave of open calls (OC1). This application period has now officially closed. Ten applications were received from across Europe, including Spain, Germany, Estonia, the Netherlands, Belgium and the UK. Following a rigorous evaluation based on excellence, impact and capacity, six applications were selected for support comprising three startups, two SMEs and one large enterprise.
These open calls are unique because they provide fully supported services rather than financial grants. Selected participants gain access to the nine pilot lines, utilising world-class equipment for manufacturing and performance testing. They also receive guidance on certification and compliance from partners like Bureau Veritas, alongside non-technical support such as market analysis and networking with investors.
For those who missed the first window, a new wave of open calls is coming later this year. All European innovators are encouraged to keep in touch and follow us for more information on how to secure this supported access to industrial readiness.
Conclusion
The success of the first open calls marks the transition of CLEANHYPRO from a planning phase to an operational reality. We are opening our doors to European innovators who share our vision of a sustainable, cost-effective hydrogen economy. The support offered through the open innovation test bed is the fastest, lowest risk path for upscaling technologies currently between TRL4 and TRL7.
