DoE funds carbon-capture projects

The US Department of Energy (DoE) is to fund three projects with almost $1bn (£0.6) to accelerate the deployment of carbon-capture and storage technologies on a commercial scale.

In the first project, American Electric Power (AEP) will design, construct and operate a chilled-ammonia process that is expected to capture at least 90 per cent of the CO2 (1.5m metric tons per year) in a flue-gas stream at the existing 1,300MW Appalachian Power Company (APCo) Mountaineer Power Plant near New Haven in West Virginia.

The captured CO2 will be treated, compressed and transported by pipeline to proposed injection sites located near the capture facility. During the operation phase, AEP plans to permanently store the entire amount of captured CO2 in two separate saline formations located approximately 1.5 miles below the surface.

The project team includes AEP, APCo, Schlumberger Carbon Services, Battelle Memorial Institute, Consol Energy, Alstom and an advisory team of geologic experts. The 10-year project will be funded with $334m (£203m) from the DoE.

In the second project, Southern Company Services (SCS) will retrofit a CO2-capture plant on a 160MW flue-gas stream at an existing coal-fired power plant - Alabama Power’s Plant Barry - which is north of Mobile, Alabama.
