Submission + - Carbon Capture Works at Wisconsin Coal Plant

Thomas Content writes in the Milwauke Journal Sentinel that a coal-fired power plant in southeastern Wisconsin has been successful in grabbing 90% of greenhouse gas using chilled ammonia to capture carbon dioxide from the smokestack. The technology is one of several being tested by utilities that are seeking to ways to continue burning coal from their existing fleet of coal plants even if the United States embarks on a national plan to slash emissions of greenhouse gases. "One of the biggest challenges facing our industry is the development of cost effective technology that will allow us to capture carbon from the operation of power plants around the world," says Gale Klappa, chairman and chief executive of We Energies. The next phase of testing at the Mountaineer power plant in West Virginia will go one step further by testing not only the capture but the sequestration of the carbon dioxide where the gas will be compressed, pipelined, and injected into two different saline reservoirs located approximately 8,000 feet beneath the plant site. The experiment, which the company says could begin in the next few days, is riveting the world's coal-fired electricity sector, which is under growing pressure to develop technology to capture and store carbon dioxide. The technology is certain to devour a substantial amount of the plant's energy output — optimists say 15 percent, and skeptics, 30 percent leaving less electricity available to send out to the power grid and utility customers. "Key questions around energy consumption — a key driver of cost — and other important technical issues will be addressed as larger-scale demonstrations work to fully optimize the technology."
