GE Waukesha natural gas engines now EPA-certified for mobile use

WAUKESHA, Wis. -- U.S. Environmental Protection Agency has certified two of GE’s Waukesha natural gas-fueled engine models for mobile, non-road applications. GE is able to offer a new, lower cost, lower emission choice for powering drill rigs and oilfield equipment, in place of older diesel units, as producers seek to meet the country’s increased demand for cleaner natural gas by developing unconventional oil and gas fields across the U.S. and Canada.

As GE awaited the EPA’s decision to grant the mobile certification for its VHP engine family, client Patterson-UTI Drilling replaced existing diesel systems with three Waukesha VHP L7044GSI gas engines at a well site in Harrison County, W.Va.—units that received EPA permit exemptions pending the agency’s mobile certification ruling. Patterson-UTI and GE are also working to replace additional diesel units with EPA-certified Waukesha L7044GSI-EPA engines in other locations in Ohio and Colorado.

With performance ratings at altitudes up to 8,000 ft, with no de-rate, the L7044GSIEPA and L5794GSI-EPA models use Non-Selective Catalyst Reduction (NSCR) technology—commonly referred to as a Three Way Catalyst (TWC)—achieving very low NOx, CO and VOC values, enabling more cost-effective operation, and providing greater return on investment.
