The testing took place at IMI Remosa’s facility in Cagliari, where the electrolyser was validated for performance, safety, and control systems under factory conditions before shipment – minimising the risk of delays during installation and commissioning.

The FAT safeguards the buyer in Klaipėda Port, confirms IMI’s delivery, and ensures the unit arrives in Lithuania ready for seamless integration into balance-of-plant systems.

“Our engineering team worked closely with IMI to make sure the electrolyser production plant meets the highest standards for quality and safety,” explained Vaidas Belčetis, Engineering Manager at EPC firm MT Group.

“Completing the FAT is a big step toward delivering Klaipéda’s first green hydrogen station and setting a benchmark for future projects in the region.”

IMI agreed to supply its PEM electrolyser to Klaipėda Port last January, ahead of hydrogen production slated for 2026.

Once commissioned, the unit is expected to produce 127 tonnes of hydrogen per year, or approximately 350kg per day, to power vessels, trucks, buses, and port machinery located in Klaipeda.

The electrolyser is fully customisable in terms of size, capacity, and configuration, ranging from 100kW to 5MW, and can be expanded up to 20MW through its modular design.

Construction of the refuelling facility began in June following a permit granted to the Klaipėda State Seaport Authority.
