Coal is a black or brownishblack sedimentary rock that can be burned for fuel and used to generate 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.

A synthesis gas can also be created by reacting coal or biomass with hightemperature steam and oxygen in a pressurized gasifier. This converts the coal or biomass into gaseous components—a process called gasification. The resulting synthesis gas contains hydrogen and carbon monoxide, which is reacted with steam to separate the hydrogen.

Introduction The term natural gas refers to hydrocarbonrich gas; it is a gaseous fossil fuel that is found in oil fields, natural gas fields, and coal beds ( Carroll, 2010, Speight, 2007 ). The first recorded natural gas well was drilled by William Hart, who is considered to be America's "father of Natural Gas," in 1821 in Fredonia, United States.

In this process, coal is combined with oxygen and steam to produce a combustible gas, waste gases, char, and ash. The more than 70 coal gasification systems available or being developed in 1979 can be classified by the heating value of the gas produced and by the type of gasification reactor used. HighBtu

Exactly how much CO 2 is emitted in the long process of making a battery can vary a lot depending on which materials are used, how they're sourced, and what energy sources are used in manufacturing. The vast majority of lithiumion batteries—about 77% of the world's supply—are manufactured in China, where coal is the primary energy source.
