Phoenix Service Partners (“Phoenix”), in conjunction with Caterpillar Inc. (“CAT”), has successfully tested a large-horsepower gas compression system that delivers ultra-low methane emissions for the operator without requiring a connection to the power grid.

In a technical paper presented recently at the 2026 Gas Machinery Conference, Phoenix and CAT released the field trial results of an engine-mounted integrated oxidation catalyst (“IOC”) technology designed to reduce methane emissions, volatile organic compounds, and other exhaust constituents while preserving the operating advantages of lean burn natural-gas fueled engines for compression operations.

During the field trial, performed for a Phoenix customer in the Permian Basin, the unit reduced engine-out methane emissions by up to 73% relative to a standard Phoenix second-generation lean burn configuration – a configuration which already outperforms traditional compression fleets by a wide margin. VOC emissions decreased up to 90% in the trial, CO emissions decreased up to 91%, and formaldehyde emissions decreased up to 88%.

Across more than 4,000 operating hours over six months, the IOC unit moved approximately 13 million standard cubic feet per day and delivered on Phoenix’s standard 98% runtime guarantee.

Importantly, these emissions reductions were achieved without dependence on grid connectivity or stability in a remote field environment – offering all of the reliability of gas-powered compression while reducing methane emissions to a level approaching parity with electric compression.

“We aim to lead the industry, and technology is an important part of our success,” said Randy Dean, co-founder and CEO of Phoenix. “We are proud to partner with CAT in developing this new approach that will raise the bar for gas compression.”

“By reducing tailpipe emissions, this new system can not only help our customers meet their emissions objectives, but also support permitting and cost-effective site development by enabling the installation of more horsepower per location,” stated Marshall Taylor, Phoenix Vice President of Sales and Engineering.

Dan West, Managing Director at SCF Partners, said, “Operators need best-in-class reliability to keep their critical infrastructure running, and they also need to reduce emissions. With Phoenix, they can do both at once – without needing to wait for or depend upon the power grid.”
