Coal | National Geographic Society
Coal is a black or brownish-black sedimentary rock that can be burned for fuel and used to generate electricity.It is composed mostly of carbon and hydrocarbons, which contain energy that can be released through combustion (burning). Coal is the largest source of energy for generating electricity in the world, and the most abundant fossil fuel in the United States.

What is coal used for? | U.S. Geological Survey
Coal is primarily used as fuel to generate electric power in the United States. In coal-fired power plants, bituminous coal, subbituminous coal, or lignite is burned. The heat produced by the combustion of the coal is used to convert water into high-pressure steam, which drives a turbine, which produces electricity. In 2019, about 23 percent of all electricity in the United States was,

Understanding carbon capture and storage - British,
After capture, CO 2 must be transported to suitable storage sites. Pumping it though pipelines is the cheapest form of transport and is a well known and reliable technology. There are 5800 km of CO 2 pipelines in the United States transporting CO 2 to oil production fields, where the CO 2 is injected to help produce more oil. This process is called enhanced oil recovery or EOR.
