A British-Canadian consortium will develop advanced carbon capture technology specifically for gas-fired power stations in a £20m project for the ETI.
ETI, a partnership between government and several major businesses, wants to see a 5MW carbon capture demonstration plant that can capture up to 95 per cent of carbon dioxide emissions designed, built and tested by 2016.
Canadian firm Inventys will lead the consortium, working with Howden, Doosan Power Systems and MAST to develop a post-combustion capture system suitable both for new combined cycle gas turbine power stations and for retrofitting to existing CCGT plant.
ETI’s carbon capture and storage (CCS) project manager, Rebecca Sweeney, explained: “When you put capture technology onto any type of power station, there’s an inevitable penalty in terms of the cost of the electricity you’re exporting from that power station and also the additional cost of building in the equipment. Our projects in this area are focused on reducing that cost penalty.”
In the first phase, a 30kW-scale prototype will be created in Vancouver, with laboratory work and techno-economic assessment to confirm the projected benefits, then conceptual design for a larger-scale demonstrator plant.
That will be followed by further investments over three years in the detailed design, assembly and testing of a 5MW demonstrator plant in the UK.
“The total cost of the project will be in the region of £20m, and we’re hoping to be able to demonstrate that this technology can reduce the cost of electricity coming from the power station by 13 per cent compared to conventional amine capture technology,” said Sweeney.
Inventys will design the carbon dioxide capture system, based on its VeloxoTherm temperature swing adsorption process. Howden will manufacture the large rotating devices in which the carbon adsorbents will be housed, Doosan Power Systems will provide expertise in engineering design, system integration and assessing the commercial value of developing such technology, MAST will manufacture the carbon adsorbent material, and ETI member Rolls-Royce will offer specialist engineering support.
