A natural gas or methane that occurs in coal beds and has been created during the conversion of plant material to coal.
Methane released from coalbeds in the same way that natural gas is produced from other strata. Normally considered a safety hazard, the capture and utilization of otherwise vented methane can constitute an effective carbon offset.
Natural gas formed as a byproduct of the coal formation process, which is trapped in coal seams and produced by non-traditional means.
Natural gas generated during the coalification process and trapped within coal seams, commonly referred to as natural gas from coal
Methane that is produced from coalbeds in the same manner as natural gas produced from other strata. Methane is the principal component of natural gas.
Methane produced from coalbeds in the same way that natural gas is produced from other strata. See "methane."
Methane is generated during coal formation and is contained in the coal microstructure. Typical recovery entails pumping water out of the coal to allow the gas to escape. Methane is the principal component of natural gas. Coalbed methane (CBM) can be added to natural gas pipelines without any special treatment.
Coalbed methane is a very important future alternate source of energy in Canada, and all around the world, or coalbed gas, refers to methane deposits in the pores of coal seams. It is also referred to as 'sweet gas' because of its relative lack of hydrogen sulfide. It is created by the same process by which plant material is converted to coal.
