Coal Mine Gas

The green side of coal.

Coal mine gas develops during the geochemical conversion of organic substances to coal. It is present in fissures, faults and pores of coal seams and as adsorbed gas on the inner surface of coal and neighboring rock.

However, the potential danger of coal mine gas (CMG) and methane emissions can be greatly reduced when they are harnessed properly for power and heat generation. Since the early 1990s, Jenbacher gas engines product line, with an installed capacity of more than 400 MW running on coal mine gas worldwide, has provided solutions for this special application.

How does it work?

Today, most large underground hard coal mines potentially contain coal mine methane, and abandoned mine methane and can be effectively used for power and heat generation with gas engines.

Sudden changes in the composition of CMG put greater demands on the engine, however. INNIO offers a special gas mixing and engine control system that enables efficient use of this gas to a minimum CH4-concentration of only 25%.

Additionally, Jenbacher gas engines are designed to operate on full load, despite low gas pressure, high humidity, dust load, and altitude.

The generated energy can be used in the coal mine to meet electricity requirements or fed into the public power grid. Thermal energy can be used for onsite heating or fed into a district heating system.
