Everfuel A/S provided an update on the commissioning of the 20 MW HySynergy 1 electrolyser. The Company continues to progress commissioning focused on the sub-systems required to start production and delivery of green hydrogen. As previously communicated, the main electrolyser facility is ready for start-up, while some sub-systems experience delays following commissioning tests.

This is impacting the planned start-up of the HySynergy 1 facility with production now expected to commence in the second half of 2024. Testing, verification and certification is being executed in close cooperation with the electrolyser supplier, Nel, and other sub-suppliers with focus on the following areas: · High-pressure systems · Compressors · Finalisation of software and automation, documentation and certifications . Since leakage was detected in February 2024, the electrolyser supplier has been working on completing the rebuild of the deoxidiser, which removes oxygen and moisture from the hydrogen flow as part of the electrolyser's high- pressure auxiliary system.

The supplier has implemented a solution currently awaiting PED (pressure equipment directive) certification. Everfuel and the electrolyser supplier agree that a safe and long-term robust solution is in the interest of both parties. Everfuel has implemented additional safety measures to ensure integrity of the plant resulting in identification of a leakage during verification test of the rebuild gas holder, which serves a pressure balancing and safety function.

The unit requires onsite rebuild and solutions are currently being investigated by the electrolyser supplier. Everfuel and sub-suppliers have committed highest attention and priority for completing the remaining commissioning steps which are strongly interdependent with certain steps subject to specific time windows for external expertise to undertake testing and verification. As a consequence of the mentioned activities, commissioning of the main compressor, final validation of the high-pressure system and completion of the automation and software system are affected.
