Fascinating stuff. I'm originally from Derbyshire and that has a long mining history.
I've read the term 'in situ Coal-To-Gas' -is this what it sounds like?
Nick.
Nick:
generally in-situ coal to gas will likely refer to in-situ coal gasification, which is where you burn the coal in place, but control the flow of oxygen so that the gas that comes out of the second, recovery hole is a combination of hydrogen and carbon monoxide that can then be burned at the surface to generate power or provide other useful heat. (It is called producer gas).
