Depending on the compostion and the amount of CMM (data delivered by a gas prognosis) and the kind of the mine (abandoned or acticve mine) different types of utilisation are possible. An overview of proved and tested utilisation technologies depending on the CH4 - content are shown in the table below:
| Technology | CH4 [%] | Status | Products | Remarks |
|---|---|---|---|---|
| Gas engines | (25) 30 - 100 | proved and tested | Power, heat, emission reduction | since 1996 over 100 units in operation |
| Boilers / Burners - monovalent | (20) 25 - 100 | proved and tested | Heat, emission reduction | since 1980th |
| Boilers / Burners - additional | (20) 25 - 100 | proved and tested | Heat, emission reduction | since 1900 on mines |
| CMM flaring | 20 - 100 | proved | Emission reduction | used on landfills |
| Liquified Natural Gas - LNG | 50 - 100 | tested | LNG, emission reduction | 660 Mio. m³ in 2006 (US-market) |
| VAM utilisation | 0,2 - 1,2 | demonstration | - | some are in operation |
| Gas turbines / mikro turbines | 40 - 100 | demonstration | - | - |
| Fuel Cells | 30 - 100 | pilot | - | - |
