30 September 2005 - Pilot testing of a new emissions removal technology that could be capable of removing 90 per cent of carbon dioxide is to begin at a plant in Ohio late in 2006.
Cost estimates from the US Department of Energy (DOE) predict that the ammonia based process could cost less than half of the next lowest cost carbon dioxide capture technology currently being researched.
Powerspan Corp., a clean energy technology company will test its new technology at FirstEnergy's R.E. Burger plant in Shadyside, Ohio, the same power facility it recently demonstrated its Electro-Catalytic Oxidation (ECO) multi pollutant control technology.
The carbon dioxide capture process will be integrated with the ECO technology, which uses aqueous ammonia to absorb sulphur dioxide, nitrogen oxides and mercury.
Developed in conjunction with the DOE, the new carbon dioxide removal process uses an ammonia based solution to capture the CO2 in flue gas and prepare it for subsequent sequestration; after regeneration the ammonia solution is recycled.
Initial laboratory testing conducted by Powerspan has demonstrated 90 per cent carbon dioxide removal under conditions comparable to a commercial-scale absorber.
