Coal Mine Gas

Our solution

Working with its partners, Green Gas has built a reputation for solving CMM problems. By integrating the technical solutions needed at every stage of gas-release from coal seams with the efficient utilisation of the resulting gas flows, Green Gas helps gas owners to maximise revenues from the sale of power, heat and carbon credits.

To facilitate the subsurface stage of this process, Green Gas employs international best practice techniques for gas capture at high purity from underground sources, taking into account the local geological setting and mining methods.

In the proportions dictated by local conditions, the resulting commercial-quality gas streams will be a combination of gas which has been:

  • Drained directly from the seams before mining
  • Drained from gas horizons affected by the mining process, and
  • Collected from voids left behind after mining.

Our solution:
























By 'capturing' gas in this way, Green Gas is able to facilitate a significant improvement in mine safety. This is because the gas that would otherwise flow into the working areas of the mine is instead removed from the mine at a safe concentration.

Green Gas utilises the captured gas in a combination of class-leading high-temperature flares and combined heat and power (CHP) plants, designed and operated to maximise the value from the gas resource.

By adopting this integrated approach Green Gas has become an industry leader, closely matching the specification of the utilisation equipment to the optimised and accurately-predicted gas flows, enabling the equipment to be operated continuously at maximum efficiency.

Partners benefit from:

  • Improved coal mine safety and productivity
  • Reduced greenhouse gas emissions
  • Fossil fuel energy sources replaced with green energy
  • Additional revenue from the sale of heat, power and carbon credits
