2019-11-16Coal gasification processes under active consideration for commercialization have been divided into three categories high, medium and low Btu gas processes. It has been determined, based on available environmental data, that high and medium Btu gasification processes have moderate to good probabilities of achieving environmental acceptability.
2 Coal is a chemically complex substance, naturally containing many trace elements including mercury, selenium and arsenic. The combustion of coal can result in trace elements being released from power stations with potentially harmful impacts to both human health and the environment.

Coal is one of the most plentiful and least expensive fossil fuels in world, and currently accounts for almost 40 percent of energy production in the U.S. The availability and affordability of coal come with trade-offs regarding its effects on the environment, particularly the atmosphere.
Coal gasification is looking to be the solution to the pollution problems that have led some of the country to a standstill. Although there are problems coal gasification actually produces more CO2 than traditional coal plants meaning that China will be using more coal and affecting the environment just as much. The second problem is water use.
The United States Department of Energys Office of Fossil Energy, through the Gasification Systems Program, is developing innovative and flexible modular designs for converting diverse types of US domestic coal into clean synthesis gas to enable the low-cost production of electricity, high-value chemicals, hydrogen, transportation fuels, and other useful products to suit market needs.
