When coal is used to generate electricity in power plants, carbon from the coal bonds with oxygen from air to make carbon dioxide (CO2). Due to concerns about how CO2 impacts global climate, scientists at DOE's National Energy Technology Laboratory are developing materials and processes to separate and capture it from power plants for permanent disposal. Ideally, the capture process will not create new waste materials, is quick and efficient, and the CO2 ends up as a high-pressure gas that can be transported in a pipeline to be injected into an oil field or a deep geologic formation.
