Captured Mineral Methane (CMM)

Our Captured Mineral Methane (CMM) Division generates baseload power from 15 sites through the capture of CMM which is a methane rich gas accumulated over time in closed mines.

CMM is extracted in a controlled way by applying suction through the mine openings, or through boreholes.

It is then converted to electricity using CMM as a fuel source for modular reciprocating gas engines - exactly the same way as for Captured Landfull Methane (CLM).

Each year we capture in excess of 40,000 tonnes of methane in our CLM division.
