American Power Group's Initial V6000 Dual Fuel Demo Truck Test Yields An Impressive 60% Diesel Displacement Rate Resulting in Net Fuel Savings of 25% to 30%

ALGONA, IA / ACCESSWIRE / May 16, 2022 / American Power Group Corporation ("APG") (OTC PINK:APGI) today announced the results from a month-long test drive of APG's V6000 Dual Fuel system by Sapphire Gas Solution, ("Sapphire") a Conroe, Texas based industry leader in mobile RNG, LNG, and CNG services across the U.S. Sapphire has been using APGI's 2015 Freightliner CC132 Coronado Sleeper with a Detroit Diesel 505HP diesel engine upfitted with APG's new V6000 Dual Fuel system to pull heavy-haul LNG tankers with a combined truck/tanker load approximating 80,000 pounds across Texas.

Sam Thigpen, CEO of Sapphire Gas commented, "We have been impressed with the performance and results of operating APG's new V6000 Dual Fuel truck. Our drivers reported the truck "performed like a diesel engine with no difference in power or torque" while operating APG's Dual Fuel system and their new natural gas telematics system allowed us to validate a consistent on-road displacement rate of near 60% with an overall average route diesel displacement of approximately 50% when running on dual fuel. Based on our current fuel costs, this equates to an impressive 25% to 30% net fuel savings of $1.40 to $1.70 per gallon over 100% diesel fuel which is currently around $5.30/gallon in Texas. Based on these initial results and APG's low cost of conversion, we can now have a more productive discussion regarding dual fuel and our fleet."

Matt Van Steenwyk, APG's Chairman responded, "I am delighted, but not surprised to hear the positive feedback from Sapphire's month-long evaluation of our new V6000 Dual Fuel demo truck. We have repeatedly proven over the years that we can safely displace a high percentage of diesel fuel with LNG, RNG, CNG, or treated flare gas with no loss of power or torque on engines ranging from 400-600HP Class 8 diesel trucks to 1500-3000HP off-road generators and diesel pumps. Sapphire and the thousands of existing people and organizations that rely on diesel engines have a ‘ready now', inexpensive solution for the reduction of criteria pollutants and carbon emissions that costs less to operate and, when running on diary RNG, actually can turn the carbon clock backwards."

Chuck Coppa, APG's CEO/CFO stated, "With diesel prices continuing to soar, our ability to provide fleet operators with a 25% to 30% net fuel savings is significant. In addition, from a de-carbonization perspective, our V6000 dual fuel system displacing 50% to 60% of diesel consumption with domestically available RNG from dairy manure could eliminate between 500 to 610 metric tons of CO2 per year per vehicle and generate a significant negative Carbon Intensity Score (-104 to -145 gCO2e/mj)."

Mr. Coppa added, "With approximately 2 million late-model Class 8 diesel trucks operating in the U.S. and assuming an estimated CO2 reduction of 500 metric tons per truck per year that equates to the elimination of potentially 1 billion metric tons of CO2 reduction per year. With these third-party validated results, we have a real opportunity to take existing diesel fleets and convert them to low-carbon or even negative-carbon green fleets when using RNG today!"

American Power Group and Sapphire Gas Solutions will be attending and highlighting their dual fuel experience at the RNG Coalition Summit in Houston, TX on May 17-19, 2022. The APG V6000 Dual Fuel demo truck and Sapphire's LNG Tanker will be available to view on Tuesday May 17^th.
