en.Wedoany.com Reported - British green hydrogen technology and manufacturing group Clean Power Hydrogen (CPH2) has decided to abandon its membrane-free electrolyzer manufacturing plans. This follows a severe failure of its 1 MW MFE220 unit during factory acceptance testing, which the company assessed as irreparable for continuing the testing process, forcing a strategic shift from manufacturing to commercial operations.

The failure occurred during the third and final phase of testing, as the equipment was executing a standard shutdown procedure. CPH2 stated that the cause of the incident is still under investigation. Technical and operations leaders believe that a major redesign of the product solution is required before a design can ensure the safe operation of the mixed gas system under all operating conditions.

The company stated in a release that it currently lacks the financial, engineering, or technical resources required for a redesign, resulting in significant uncertainty regarding its ability to continue as a going concern. Its shares on London's AIM market remain suspended, and financing negotiations with shareholders and potential new investors have also been terminated.

CPH2 emphasized that its intellectual property still holds considerable commercial value and is currently exploring technology licensing and other viable options to maximize value for shareholders and stakeholders. This situation stands in stark contrast to the company's previously optimistic outlook—it had planned to complete factory acceptance testing in May and recently signed a non-binding memorandum of understanding with Siemens to advance capacity expansion.

This incident highlights the practical challenges faced in transitioning hydrogen electrolysis technology from proof-of-concept to commercial deployment, particularly when safety issues, engineering changes, and funding pressures emerge simultaneously.
