The environmental impact of CBM

World Coal,


Natural gas has seen an increase in interest as an energy resource due to its lower greenhouse gas (GHG) profile and the impact of the shale gas revolution in the US. This does not mean, however, that natural gas is without impact on the climate.

The environmental impact of various types of natural gas were recently calculated using a life cycle environmental model for natural gas that has been developed by the US National Energy Technology Laboratory and peer reviewed by several external sources. The model accounts for all significant activities in the life cycle of natural gas power generation. The boundaries of the model begin with the extraction of raw natural gas, include gas processing, pipeline transport, power plant operations and electricity transmission, and end with 1 MWh of electricity delivered to an end user. Environmental burdens include the air emissions and resource consumption that result from construction and operation of equipment, fugitive and point source emissions of natural gas and the combustion of fuel for energy.

In this white paper, Tim Skone, NETL, and James Littlefield, Booz Allen Hamilton, discuss the upstream and downstream emissions and water footprint of different types of natural gas product, including coalbed methane (CBM), as described by the NETL model.
