Corinth Pipeworks secures major award for HyNet CO² Pipeline in Liverpool Bay

Cenergy Holdings announces that Corinth Pipeworks, its steel pipes segment, is participating in the Liverpool Bay Carbon Capture and Storage (CCS) project in the United Kingdom. The project is operated by Eni as part of the HyNet industrial cluster and marks a key milestone in the UK's energy transition and decarbonisation roadmap.

Under this contract, Corinth Pipeworks will supply and deliver approximately 41 kilometers of Longitudinal Submerged Arc Welded (LSAW) steel pipes and hot induction bends, in diameters of 20", 24" and 36", complete with external anti-corrosion coating, for the onshore and offshore sections of the CO₂ pipeline system.

The Liverpool Bay CCS project forms the backbone of HyNet, one of the world's most advanced CCS clusters, which aims to capture and permanently store industrial CO₂ emissions from the North-West of England and North Wales. The infrastructure will transport captured CO₂ through new and repurposed pipelines to be safely stored in Eni's depleted gas reservoirs beneath Liverpool Bay.

"We are honored to contribute to a project of such strategic importance to the UK's decarbonization goals and global climate efforts," said Ilias Bekiros, General Manager at Corinth Pipeworks. "Our advanced technology, high standards for sour service applications, and

commitment to sustainable practices make us a trusted partner for low-carbon infrastructure projects across Europe and beyond."

This contract underscores Corinth Pipeworks' leading position in the European CCS market, supporting key initiatives in carbon management and enabling industrial decarbonization through the delivery of high-specification pipe solutions.
