How is it work:
Believe it or not, gasification has been around for decades. Scottish engineer William Murdoch gets credit for developing the basic process. In the late 1790s, using coal as a feedstock, he produced syngas in sufficient quantity to light his home. Eventually, cities in Europe and America began using syngas -- or "town gas" as it was known then -- to light city streets and homes. Eventually, natural gas and electricity generated from coal-burning power plants replaced town gas as the preferred source of heat and light.
