Coal gasification current technology

A major reason for the difference between the target and current technology is the chemistry chosen and the way the flow sheet is put together. At present, CTL processes produce syngas (CO and as an intermediate by gasification of coal, and then convert the syngas into hydrocarbons by the Fischer-Tropsch process. The target for this route can also be calculated.

CS Size Hydrogen via Coal Gasification with Current Technology... 

With these factors in mind, the availability of pipeline-quality gas from coal may be projected to rise from about 0.1 Tcf in 1976 to 0.3 Tcf annually by 1980, with these volumes most likely entirely attributable to Lurgi-type plants. Gas available from added facilities based on the newer process technologies currently under development is projected to bring the total annual volumes of gas available from coal gasification to about 1.4 and 3.3 Tcf, respectively, in 1985 and 1990. 

Although no coal gasification-based polygeneration plant that coproduces hydrogen and electricity currently exists, the technologies required for such a plant are fairly mature. Many heavy oil-based facilities, which utilize similar technology, have already been in operation. There have been many studies and analysis conducted to evaluate the system performance and economics of such coal-to-hydrogen systems.
