The technology captures CO2 emissions from coal- or gas-fueled power facilities, cement plants and refineries, and converts it into solid carbonates that can be used as building materials in the form of aggregates or other cement-type materials.
Fredrick Palmer, senior vice president of Peabody, said: “Peabody is a global leader in clean energy solutions and is advancing more than a dozen projects and partnerships to commercialize low-carbon technologies. Calera’s emerging technology represents an innovative solution to advance our energy, environmental and economic goals by recycling carbon dioxide into beneficial building products.”
California-based Calera recently completed a demonstration project near Moss Landing, California, which used the emissions stream from a natural gas-fueled power plant. The Calera technology mixes CO2 with water from a variety of sources, causing the minerals to bond and release as synthetic limestone.
Peabody’s clean coal initiatives include serving as the only non-Chinese equity partner in China’s GreenGen power project; a founding member of the US FutureGen Alliance; and a founding partner of Australia’s COAL21 low-carbon project.
The company also is a founding member of the Global Carbon Capture and Storage Institute; the US-China Energy Cooperation Program; the Asia Pacific Partnership for Clean Development and Climate; the Consortium for Clean Coal Utilization; the National Carbon Capture and Storage Center; and others.
