1MW MFE220 Factory Acceptance Test update

 

 

Clean Power Hydrogen plc (AIM:CPH2), the developer of market disrupting and
IP-protected Membrane-Free Electrolyser ("MFE") technology for the
co-production of high purity hydrogen and above medical-grade purity oxygen,
provides an update on the third and final Factory Acceptance Test ("FAT") of
its MFE220 1MW unit.

In the final stages of testing at the Company's dedicated and secure test site
facility in Rossington, near Doncaster, the unit experienced an unexpected
error, causing it to commence a standard shutdown procedure. During that
shutdown procedure, the unit experienced an incident which has caused
significant damage to the equipment. In line with the Company's health, safety
and environmental protection processes, all operations have been suspended and
a thorough investigation is underway into the causes of the original error and
the subsequent failure.

This unfortunate incident will materially delay successful completion of the
FAT for the MFE220 unit which was previously expected during May 2026 and the
Company will provide further updates in this regard in due course.

The Company also confirms it has been engaged in discussions with certain
existing shareholders and prospective new investors regarding a potential
equity capital raise to support the next phase of technical and commercial
development following completion of the FAT. In light of the incident during
testing, these discussions have been paused pending greater technical clarity.
As a result, the Company has a constrained working capital position and the
Board is actively evaluating potential funding and strategic options to
resolve the immediate liquidity requirement.

The Company is reviewing its insurance position in relation to the incident
and assessing the potential implications for its commercial arrangements with
customers. These discussions and investigations are ongoing and, while the
full impact on timing and contractual outcomes remains under review, the Board
is focused on establishing a clear path forward and will provide further
updates as appropriate.

Due to the ongoing uncertainty regarding the Company's financial position, its
current limited working capital and the circumstances noted above, the Company
has requested that its shares are suspended from trading on AIM with effect
from 7.30 a.m. today.

Commenting, Chief Executive Officer of CPH2, Jon Duffy, said: "This is a
disappointing outcome as we approached the final FAT Level 3 testing. However,
we will immediately start work towards resolving this technical issue so that
we are able to minimise any commercial impact on our business."
