The biggest problem with Coal gas is that the 2 useful burnable substances are hydrogren and carbon-monoxide. Both are problems! I designed gas detection systems for leaks on 2 of the pilot plants, in the mid 90's.
GE finally bought the TEXACO division which was working on coal gas. They are located here in Houston, headquartered in the Post Oak area.
