Two 'world leading' carbon capture projects primed for construction in the UK

The 'trailblazing projects' will break ground at cement works in Flintshire, North Wales, and a waste-to-energy facility in Cheshire.

The UK’s first carbon capture-enabled cement plant at Padeswood, developed by Heidelberg Materials UK, and one of the world’s first, full-scale, carbon-capture-enabled, waste-to-energy facilities at Protos in Ellesmere Port, developed by Encyclis, have signed final contracts with government to begin construction.

They will generate 500 workers in North Wales and the North West.

These are the first two anchor projects to join Eni’s Liverpool Bay Transportation & Storage network, part of the HyNet carbon capture cluster which was green-lit by the Prime Minister in April.

HyNet is a network of new and repurposed infrastructure, such as pipelines, spanning North Wales and the North West of England that will capture carbon emissions and store them safely underground.  

The carbon capture facility at Padeswood is designed to capture almost all (around 95%) of the CO₂ emissions from the process. The emissions captured from the kiln include biogenic CO₂ from biomass fuels, mainly from domestic food, wood and paper wastes that cannot be recycled, which could allow the cement produced at Padeswood to be net negative.

The carbon captured at Padeswood will be compressed and transported via an underground pipeline for secure storage under the seabed in Liverpool Bay.
