Just look at the map of where the biggest sources of atmospheric methane are located and then look at a map of the biggest coal deposits. Quite a match, don’t you think. Coal seams are one of the bigger natural sources for atmospheric methane. If we started to cultivate them as methane factories for clean energy, we reduce one big source of methane that goes where it does not belong and power on our economy at the same time. Win-win.
CBM refers to methane that is found in coal seams. It is formed during the process of coalification, the transformation of plant material into coal. CBM is also known as virgin coal seam methane or coal seam gas.
