Researchers at Colorado State University will lead a $1.8 million, federally funded study of how much air pollution in the oil and gas industry comes from compressor stations, which ensure natural gas is able to flow down a pipeline.

The two-year study, led by Daniel Zimmerle, senior researcher at CSU’s Energy Institute, will look at pollution coming from 80 compressor stations nationwide and more than 300 individual compressor units.

Methane is a major component of natural gas and also a greenhouse gas that’s 84 times more potent than carbon dioxide over a 20-year timeframe, according to CSU.

Natural gas pumped out of individuals wells is “gathered” into pipelines. Compressor stations act to increase the pressure of the gas for transport via the pipelines to processing plants and the larger national network of natural gas pipelines.
