Clean Coal by What Definition? | Pembina Institute
Clean coal is and should be defined as the use of coal to produce electricity or heat, which results in zero emissions to the atmosphere. Technology that comes close to this does exist — through the process of coal gasification with the resulting emissions captured and stored underground. Such plants are operating in Europe and the U.S.Web
