Net Zero CO2 burial plan 'spur' will need 11km trench across NE Wales

16-INCH PIPELINE WOULD TAKE GAS FROM CEMENT WORKS CARBON CAPTURE TO DEPLETED NATURAL GAS FIELDS UNDER BAY

- By OWEN HUGHES

A Net Zero proposal would see an 11km trench dug across Flintshire and under the A55.

The scheme is part of the wider HyNet project that is set to take CO2 from high energy consuming businesses in North Wales and North West England and transport it to depleted gas fields under Liverpool Bay.

A plan is now in for the Padeswood Spur Pipeline to transport CO2 from the new carbon capture plant at the Heidelberg Materials UK cement works in Padeswood, to the HyNet Carbon Dioxide Pipeline at Northop Hall.

The pipeline will be approximately 11km in length, running between Mold and Buckley before crossing under the A55 near Northop Hall.

It is anticipated that if planning permission is granted for the Padeswood Spur Pipeline, that construction works will start in September 2026 and continue until February 2028.

The majority of the pipeline route will be installed by open trench construction methods.

The working width will be wide enough to allow construction activities to take place safely and efficiently. A standard construction corridor width of 25m is proposed.
