It is part of a group testing a novel process of injecting CO2 into Alberta´s vast, deep, unmineable coalbeds to release the trapped methane.

This process is called Enhanced Gas Recovery (EGR) and is similar to the popular practice of using carbon dioxide injection to enhance production from oil reservoirs.

With coal-based EGR, the injected CO2 is adsorbed in the coal and stored in the pore matrix of the coal seams, releasing the trapped methane.
