APG GreenMan Targets the Frack Patch

American Power Group reports favorable emission results paving the way for its diesel-natural gas dual fuel retrofits for the many powerful engines used in hydraulic fracturing for natural gas.

American Power Group is aiming its dual fuel conversion technology at the numerous powerful engines used in natural gas fracking.

As elsewhere in oil and gas, large engines have run successfully on a diesel-natural gas mix – APG alone claims more than 45 installations – and the trend is spreading to the more numerous and much larger engines for the pressure pumps that enable fracking.

There’s far more fuel burned at a fracking site than most truck fleets use, says APG CEO Lyle Jensen.

Thousands of Powerful Engines

“During the past fifteen months, we have gone from two initial installations in the oil and gas industry to over 45 retrofits to-date,” Jensen says – with “the most popular lower horsepower 1475 HP engines traditionally used by the major oil and gas exploration companies.”

But, Jensen says, “While a traditional oil and gas drilling site operates three diesel engines, a typical hydraulic fracturing site is comprised of up to twenty high-horsepower diesel pumps.

“Our initial target market is the estimated 2,000 new high horsepower diesel pumps being deployed by the hydraulic fracturing industry annually in the United States,” he said in a release.

Used non-road compression ignition (diesel NCRI) engines represent the engineering and economic sweet spot, APG says, for its “non-invasive” through-the-air-intake natural gas fumigation system. Diesel displacement is less than with OEM fuel injection, but the engines run cooler, APG says, retain OEM diesel compression ratios and oil-change intervals, avoid fuel-injector cost and maintenance issues, and can return to full diesel operation anytime.

“The proprietary technology seamlessly displaces up to 80% of the normal diesel fuel consumption with the average displacement ranging from 40% to 65%.”

Citing success with Australia’s Wesfarmers and others, APG continues to pursue on-road opportunities for its duel fuel system as well.

APG is offering the upfits under the U.S. EPA’s Memo 1A process, whereby “a company must demonstrate good, sound engineering judgment and have sufficient, reliable data which clearly demonstrates the conversion technology is emission compliant for that appropriate model year converted.

A Partnership with Linde for LNG Delivery

“Therefore, while no specific EPA approval is granted under this process, we are highly confident our emission results are defendable if audited,” APG says.

Using the Memo 1A alterative process, the company explains, emission testing was conducted “on a popular 2,500HP IUL (connoting an engine of intermediate age) by a third party per NRCI constant speed engine D2/ 5 Mode protocol in accordance with EPA 40 CFR Part 89 Appendix B and utilizing EPA 40 CFR 89 specified test equipment, equipment calibration, and test methodologies.

“The resulting emission levels of APG’s dual fuel system were lower than the EPA Tier 2 emission standards in effect for the applicable tested engine,” states an APG release.

For delivering natural gas fuel to the frackers, APG has formed a partnership with Linde for LNG.

APG is the sole operating business of parent GreenMan Technologies (OTCQB:GMTI).
