Clean Power Hydrogen has completed an investigation into a May 2026 system failure of its 1MW membrane-less electrolyser. The company determined the fault was due to operational issues rather than fundamental design flaws and subsequently ended a planned £750,500 loan deal with Hidrigin.
Why it matters
The findings help clear the path for the company to continue refining its proprietary membrane-less architecture. Stabilizing the technology is critical for the firm as it moves toward potential manufacturing partnerships across the US, Canada, and Mexico.
The investigation into the MFFE220 unit failure confirmed the core membrane-less electrolyser architecture is sound at its 1MW capacity. Engineers identified specific gas flow and valve configuration issues alongside particle contamination as the failure drivers.
The players
Clean Power Hydrogen
A UK-based manufacturer developing membrane-less electrolysis technology for hydrogen production.
Hidrigin
An Ireland-based engineering and manufacturing firm previously linked to a potential partnership and loan arrangement.
The details
The MFFE220 unit, a 1MW system designed to generate hydrogen without the use of traditional ion-exchange membranes, suffered significant damage during factory acceptance testing. Engineers attributed the failure to gas flow and valve configuration errors that allowed particle contamination to compromise internal systems. The team is currently redesigning these components and implementing stricter manufacturing controls to align with European Industrial Gases Association safety guidance.
Timeline
May 2026: The MFFE220 electrolyser unit failed during factory acceptance testing.
June and July 2026: The company raised over £10 million in new capital.
The Tech Race
Clean Power Hydrogen is realigning its technical roadmap to meet rigorous international safety standards. The company is now pivoting away from the failed Hidrigin loan to focus on broader manufacturing partnerships in the US, Canada, and Mexico.
Stakeholders and potential industrial customers can expect the company to move forward with manufacturing design improvements as it secures new funding. The shift in partnership strategy suggests a focus on scaling production across North America and Europe.
The takeaway
The company maintains that its core technology remains viable despite the recent testing setbacks and the termination of the Hidrigin agreement. Watch for future announcements regarding new manufacturing partners as the firm integrates its updated design controls.
