Significant Opportunities for Dual Fuel to Accelerate RNG/CNG Usage in Heavy-Duty Transportation Adoption ALGONA, IA / ACCESS Newswire / May 18, 2026 / American Power Group Corporation (OTC Pink:APGI) the leading U.S. based dual fuel diesel engine conversion technology company today shares some of their CEO's insights from his attendance at the Advanced Clean Transportation ("ACT") Expo held May 4-7, 2026, at the Las Vegas Convention Center, Las Vegas, Nevada. The ACT Expo is the largest fleet technology show which delivers peer-vetted, field-tested insights from fleets, OEMs and technology providers who put advanced solutions to work. Chuck Coppa, APG's CEO/CFO, stated, "I attended multiple presentations featuring some of the biggest names in heavy-duty trucking industry including OEMs, fleet operators as well as fueling and technology companies which provided great insights into the challenges as well as opportunities facing the transportation sector. In every presentation I attended, the underlying sentiment was that any solution must be cost-effective and make good business sense before the decision to deploy is made which is why APG's proven dual fuel solution makes so much sense here."Mr. Coppa added, "I especially enjoyed the Transport Project and California Renewable Transportation Alliance's breakout sessions addressing "The Case for RNG: The HD Trucking Solution that Delivers" which provided great insights into efforts to drive demand for cleaner burning, low-carbon RNG and other gaseous fuels in the heavy-duty transportation sector. It has been widely reported that over 80% of natural gas utilized by the transportation sector is RNG but that natural gas is only a tiny fraction of the overall fuel sources used by the heavy-duty transportation sector which is where APG's dual fuel solution can help drive significant demand. Based on annual statistical performance information obtained from the American Trucking Association, for every 1,000 of the estimated 3 million Class 8 heavy-duty SCR trucks operating in the U.S. converted to run APG's V7000 dual fuel solution, we estimate they would consume approximately 11 million GGEs ("Gasoline Gallon Equivalents") of natural gas at a 50% displacement rate. If this adoption rate increased to 25,000 trucks or approximately 1% of the overall market, the estimated total natural gas consumption would increase to 273 million GGEs. In addition, if those 25,000 trucks were running dairy RNG at a 50% displacement rate, the overall reduction in CO2 would be approximately 12.5 million tons given the beneficial emission related properties of using dairy RNG. Utilizing APG's vehicular dual fuel solution, fleet owners can avoid spending $300,000+ on a new alternative fuel heavy-duty truck by investing only a small fraction of that cost on upgrading their existing diesel truck engines with our dual fuel solution and an appropriate natural gas storage tank."Mr. Coppa concluded, "We, along with many of the presenters at ACT acknowledge there is no one silver bullet solution available today to increase demand for RNG but APG's dual fuel diesel engine conversion technology is a proven, cost-effective and readily available option to help operators and fleets start the progression towards utilizing abundant and cleaner burning domestic natural gas".About American Power Group Corporation (www.americanpowergroupinc.com)American Power Group's subsidiary, American Power Group Inc., ("APG"), provides cost-effective alternative fueling solutions for diesel engines to significantly reduce methane criteria pollutants and help accelerate a low-carbon future. APG's Dual Fuel conversion technology is a unique patented hardware and software solution that enables high-horsepower diesel engines to safely displace up to 65% of diesel fuel with natural gas. Engines equipped with APG's Dual Fuel technology can use renewable natural gas (RNG), compressed natural gas (CNG), liquefied natural gas (LNG), captured flare-stack methane and conditioned well-head gas resulting in lower cost, lower carbon, and lower criteria pollutant emissions. Additionally, APG's Dual Fuel conversion technology remains fully compatible with eligible biodiesel blends and renewable diesel fuels further reducing a diesel engine's carbon footprint and provide users with a proven regulatory compliant technology.Caution Regarding Forward-Looking Statements and OpinionsThe matters described herein contain forward-looking statements and opinions, including, but not limited to, statements relating to outstanding dual fuel conversion quotes for $2 million + and our ability to turn these quotes into actual orders.
