A pilot carbon capture project in Pleasant Prairie, Wisconsin claims to be safely sequestering carbon emissions using a chilled ammonia process.
"We Energies, Alstom and The Electric Power Research Institute (EPRI) have used, since early 2008, a patented chilled ammonia process that is able to remove over 90 percent of the carbon dioxide from the plant's flue stream. The carbon is then "compressed, pipelined, and injected into two different saline reservoirs" that are about 8,000 feet beneath the plant. The test runs through the end of this year, and the operators have already begun scaling up the system to work on larger plants that produce tons more emissions."
