Adding CCS to CCGT

The three parties will identify and develop potential project opportunities for existing and new build plants, as well as conducting feasibility and FEED studies to explore possible locations for carbon capture systems in combined cycle plants.

GE says it will build on its experience in advanced technology and control concepts to integrate DL E&C and CARBONCO capture technology with combined cycle power plants, with the goal of ensuring dispatchability, lower carbon intensity, high flexibility and reliability, and lower capital cost.

GE notes that there is an installed base of over 1300 of its gas turbines in Asia.

DL E&C and CARBONCO carbon capture capabilities include technologies able to manage CO2 emissions of more than 3000 tons per day (about 1 million tons per year), modularisation that facilitates quality control and risk management, and utilisation concepts that envisage transformation of the collected CO2 into useable compounds (eg, liquid carbonic acid) and carbon mineralisation.

“GE holds advanced power generation technologies, and DL E&C and CARBONCO have the experience of commercialising Korea’s first carbon capture plant and carbon capture plant design capabilities,” said Jae-hyung Yoo, chief executive, business development office at CARBONCO. “With the collaboration and synergy with GE, we plan to actively expand our decarbonisation business overseas.”

Meanwhile in the UK, SSE Thermal and Equinor are proposing to develop 910 MW CCGT+CCS power plants at Keadby (Scunthorpe, Lincolnshire) and Peterhead (Aberdeenshire coast, Scotland). Planning applications have been submitted.

For CO2 disposal, Keadby 3 would connect to shared infrastructure being developed by the East Coast Cluster (a collaboration between Zero Carbon Humber, Net Zero Teesside and Northern Endurance Partnership).

The Peterhead Carbon Capture Power Station (aka Peterhead 2) would have access to the CO2 transport and storage infrastructure being developed as part of the Acorn Project, which plans to sequester CO2 about 100 km offshore in rock formations CO2 below the North Sea.
