During that shutdown process, the unit suffered a significant equipment failure that caused substantial damage.\n\nAll testing operations have now been suspended while a full investigation is conducted into both the initial fault and the subsequent incident.\n\nThe setback materially delays completion of the MFE220 Factory Acceptance Test, which management had previously expected to complete during May 2026.\n\nThe timing is particularly significant as successful completion of the FAT was viewed as a critical commercial milestone for the company’s hydrogen production technology.\n\nManagement also disclosed that discussions with existing shareholders and potential new investors regarding a planned equity fundraising have been paused pending greater technical clarity around the incident.\n\nAs a result, the company warned it now faces a constrained working capital position and is actively evaluating funding and strategic alternatives to address immediate liquidity requirements.\n\nThe company is also reviewing its insurance coverage and assessing the potential impact on customer contracts and commercial arrangements.\n\nGiven the uncertainty surrounding both the technical investigation and the company’s financial position, Clean Power Hydrogen has requested a suspension of its shares from trading on AIM with immediate effect.\n\nChief executive Jon Duffy described the outcome as disappointing, particularly given the company was approaching the final level of Factory Acceptance Testing, but said efforts would now focus on resolving the technical issues and minimising any commercial impact.\n\nFor investors, the announcement represents a significant negative development. The combination of equipment damage, delayed certification, paused fundraising discussions, limited working capital and an AIM suspension creates substantial uncertainty until the company can establish both the root cause of the incident and a viable funding path forward."}
