Captured Mineral Methane (CMM)

Baseload power generated by extracting and combusting naturally occurring methane rich gas released from disused mines

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.
