Coal - Wikipedia
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is 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.

in making bridges, ships, cars, truck bodies and many other articles, the monetary loss due to rusting is huge. The process of rusting can be represented by the following equation: Iron (Fe) + Oxygen (O 2, from the air) + water (H 2 O) → rust (iron oxide Fe 2 O 3) For rusting, the presence of both oxygen and water (or water vapour) is essential.

An Introduction to CO2 Separation and Capture Technologies
Integrated coal gasification combined cycle (IGCC) plants are an example of the hydrogen route. Coal is gasified to form synthesis gas ( syngas) of CO and H 2. The gas then undergoes the water-gas shift, where the CO is reacted with steam to form CO 2 and H 2. The CO 2 is then removed, with the hydrogen being sent to a gas turbine combined cycle.
