European Hydrogen Innovation Cluster
Seven EU projects, including CARMA-H2, join forces to accelerate hydrogen innovation and deliver real-world impact.

Hydrogen is unlocked by separating it from other elements. But to realise its full potential for the energy transition, it takes connection – uniting expertise, innovation, and commitment across borders.
That is the purpose of the European Hydrogen Innovation Cluster: an alliance bringing together pioneering European initiatives to accelerate clean hydrogen research and technologies. Among them is CARMA-H2, which collaborates with six sister projects to amplify impact and transform innovation into real solutions for a sustainable future. The other participating projects are:
- ANDREAH: Creates advanced ammonia cracking technology to deliver ultra-pure hydrogen at lower costs.
- AMBHER: Develops green ammonia for long-term energy storage and MOF-based materials for short-term hydrogen storage.
- APOLO: Designs ammonia-to-hydrogen systems for fuel cells and engines to decarbonise the maritime sector.
- CARMA-H2: Develops a protonic membrane reformer to produce purified, pressurized hydrogen and food-grade CO₂, demonstrated at a wastewater treatment plant in Spain.
- HERMES: Develops palladium and carbon-based membranes to cut hydrogen purification costs.
- HYIELD: Aims to convert biogenic waste into ultra-pure green hydrogen, with a demonstration plant at CEMEX’s cement factory in Spain.
- MEASURED: Demonstrates advanced membranes for gas separation and carbon capture in industrial settings.
