Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Th e process of converting coal into electricity has multiple steps and is similar to the process used to convert oil and natural gas into electricity: 1. A machine called a pulverizer grinds the coal into a fi ne powder. 2. Th e coal powder mixes with hot air, which helps the coal burn more effi ciently, and the mixture moves to the furnace. 3.

Coal boilers also use small amounts of water for boiler blowdown. In this process, water is bled from the boiler to get rid of impurities that accumulate and form sludge that can impair a plant's performance. A more efficient coal technology, called integrated gasification combinedcycle (IGCC), is being commercialized.

The scenarios laid out by the IPCC make it clear that global coal use has to collapse to reach degrees. Coal use needs to fall by 75% by 2030, relative to 2019 (see Carbon Brief graphic below). That's much faster than gas or oil, which need to fall by 10% in the median scenario. In addition, coal is the only fossil fuel that needs to be phased out by 2050.

To produce hydrogen from coal, the process begins with partial oxidation, which means some air is added to the coal, which generates carbon dioxide gas through traditional combustion. Not enough is added, though, to completely burn the coal only enough to make some heat for the gasification reaction. The partial oxidation also makes its own ...
