Penspen wins detailed design contract for the Flintshire CO2 pipeline

Penspen was awarded detailed design by United Living Infrastructure Services, covering six valve stations and a branch to Padeswood cement works.

Penspen was reported to have won the detailed design contract for the HyNet CO2 pipeline through Flintshire, awarded by United Living Infrastructure Services. The scope includes six valve stations and five major installations, including a 35 by 30 metre valve station at Aston Hill, Mancot, and a branch to the Padeswood cement works. Total investment across the project was reported at around £5.5 billion.

Why it matters for contractors

Padeswood is close to Buckley, so Mount Pool Retreat is a short drive from one of the key connection points.
