I started with coal gasification, followed by water shift reactions to produce a typical syngas having a 2:1 H 2 /C mole ratio. The quality of this coal, as indicated by its effective H/C ratio, is poorer than that of petroleum coke, but it costs about 23 normalized units, compared with 12 for coke (Table 1).

Clean coal technologies ideas are looking to use a relatively polluting fossil fuel in a less polluting way. Controversial for a number of reasons, including the belief the term is an oxymoron, there is still huge impetus to explore them.. Huge coal reserves still exist in many parts of the world. We also seem to have difficulty in seeing beyond fossilrelated fuels for our transportation needs.
Coal gas is a flammable gaseous fuel made from coal and supplied to the user via a piped distribution system. It is produced when coal is heated strongly in the absence of air.

Underground Coal Gasification (UCG) is a process for exploiting coal that cannot be mined because the seams are too deep, thin or fractured. Exploratory licenses have been granted for the Dee Estuary (Cluff Natural Resources) and Liverpool Bay (Riverside Energy). The process involves using the same sort of drilling technology usually used for fracking to.
