Linde North America announced that its solution for using liquefied natural gas (LNG) to fuel power-generating diesel engines (gensets) is getting good grades during testing in southwest Pennsylvania.

Linde North America is a member of The Linde Group, a world –leading gases and engineering company.
The test is being conducted by CONSOL Energy’s gas division.  A publicly owned Pittsburgh-based producer of coal and natural gas, CONSOL Energy has active exploration and production operations in the Marcellus and Utica shales. CONSOL Energy has been testing the solution in three diesel engine-based gensets to produce power used by drilling rigs.

“We’re looking forward to verifying the expected cost savings and emissions reductions, and then taking advantage of these benefits throughout our rig fleet,” said Steve Winberg, CONSOL Energy’s vice president of Research & Development.

The hybrid LNG-diesel solution, which lowers the cost of producing on-site power at oil and gas sites and burns cleaner than pure diesel, is a collaboration between Linde and American Power Group (APG). Linde provides expertise in the production, supply, logistics and on-site application of LNG.  APG provides a patented dual-fuel technology that converts diesel engines to run on an average of 40 to 60 percent natural gas.

“We see a bright future for LNG in dual-fuel and dedicated engine applications,” said Bryan Luftglass, head of strategic market and business development for Linde Energy Solutions’ LNG business. “We’re delighted to be working with innovators such as CONSOL Energy that are demonstrating leadership in adopting this cutting-edge technology.”
