CMM (Coal Mine Methane) is an activity whereby mine gas, largely methane, is extracted from abandoned coal mines and used for power generation to feed the electricity supply grid.
We have been producing electricity for more than 20 years and have worked on more than 25 abandoned coal mines. We have experience in developing and operating (24/7) CMM sites using modular reciprocating gas engine generating sets. In some cases the gas is extracted via a disused mineshaft where left unfilled by the previous mine operator, while in others we drill a borehole steered from surface to intercept a previously identified target location in the mineworkings.
Our CMM generation sites range in size from around 1MWe up to 10MWe, the capacity being a function of the volume of the underground void space and the gas content of the coal seams in the locality. We also sell mine gas direct to an end consumer.
Our CMM activities are largely based in the central belt of the UK in the Yorkshire, Nottinghamshire, Derbyshire and Staffordshire Coalfields and operate under licences granted by government via the Oil and Gas Authority (OGA).
