Coal pollution mitigation emissions of sulfur dioxide or oxides of nitrogen associated with the utilization of coal in the generation of electricity." Before being adopted in this fashion, historically "clean coal" was used to refer to clean-burning coal with low levels of impurities, though this term faded after rates of domestic coal usage dropped. The term appeared in a speech to mine workers in 1918, in context indicating coal that was "free of dirt and impurities." In the early 20th century, prior to World War II, clean coal (also called "smokeless coal") generally referred to anthracite and high-grade bituminous coal, used for cooking
Carbon capture and storage (timeline) intent to establish the Clean Energy Commercialization Centre. CECC aims to accelerate the development in China of clean coal conversion technologies and the creation of associated value chain investment opportunities through the commercialization of key technologies and coordinated management of large scale demonstration projects which primarily use coal as feedstock for fuel production, chemicals manufacturing and power generation. "Carbon Capture Journal" focuses on industrial carbon capture from power stations and industrial plants and carbon dioxide underground storage, including new technology, policy and projects. Since launching the website in May 2007, it has been actively sought out by the carbon capture
