Gasification of coal is the oldest method for the production of hydrogen. Coal gasification is a process that converts coal from a solid to a gaseous state. The gas that is created is very similar to natural gas and can be used to produce chemicals, fertilizers, and/or the electric power [1]. Cleanest of all coal-based electric power technologies, gasification has significantly lower levels of air emissions (including volatile mercury), solid wastes, and wastewater.Due to its high efficiencies, gasification also uses less coal to produce the same amount of energy, resulting in lower carbon dioxide (CO2) emissions. Some scientists believe that CO2 in the atmosphere contributes to a "greenhouse effect" that will lead to the global warming. Coal gasification has a proven technology for capturing CO2 at a fraction of the cost required for coal combustion technologies.
