CARMA‑H2

Carbon-negative pressurized hydrogen production from waste using an energy efficient protonic membrane reformer CARMA-H2

CARMA‑H2 is an EU co-funded project, supported by the Clean Hydrogen Partnership, demonstrating an innovative solution to produce clean hydrogen from biogas derived from organic waste. At the heart of the project is the protonic membrane reformer (bioPMR), which integrates multiple process steps into a single compact unit, delivering pressurised, high-purity hydrogen.

The pilot system, installed at the Arazuri wastewater treatment plant (Navarra, Spain), will operate for over 4,000 hours, producing up to 500 kg of hydrogen and over 4,000 kg of food-grade CO₂ per day. With its fully decentralised, carbon-negative approach, CARMA‑H2 supports the transition to a circular and climate-neutral energy system, especially for local communities.
