Aberthaw Fact Sheet: Carbon Dioxide Capture and Storage Project

Company/Alliance: RWE nPower and Cansolv

Location: Aberthaw Power Station, Wales

Feedstock: Coal

Size: 3 MW slip stream from 1.5 GW power station (50 T/day)

Capture Technology: Post combustion

CO2 Fate: N/A

Timing: Start (January 13, 2013) Finish (May 2014)



Scale-up: Demonstration plant >25MW at Tilbury or Blyth power station. Cost of £50million. This did not go ahead.


Over the past few years, RWE has been increasing its reliance on gas and renewables and it is expected that Aberthaw will be the last of RWE nPower’s current fleet operating on coal by the end of the year.

RWE nPower expects the Aberthaw plant to help it optimize CCS technology and provide an insight into reducing emissions from coal power stations and the viability of running a full-scale carbon capture facility in conjunction with normal power plant operations.

RWE nPower operated a 1 Tons/day demo plant at Didcot Combustion Test Facility. This project was commissioned in 2008 and used a generic amine capture. The plan was to operate Aberthaw for 2 years before possibly increasing the pilot to a demonstration plant capturing 4000 Tons/ day.
