American Power Group and Aemetis Biogas Conduct Multiple California Demonstrations of American Power Group's V6000 Low-Carbon Dual Fuel Solution for Class 8 Trucks

ALGONA, IA / ACCESSWIRE / October 3, 2022 / American Power Group Corporation ("APG") (OTC PINK:APGI) and Aemetis, Inc. ("Aemetis") (AMTX), a renewable natural gas ("RNG") and renewable fuels company demonstrated APG's V6000 Low-Carbon Dual Fuel Solution last week in California for multiple truck fleet owners and operators who transport various products for Aemetis and other businesses in the region. In addition, the group presented to several regulatory agencies and policy makers in Sacramento. Based on existing and anticipated fleet interest, APG's 2014 Freightliner CA125 Cascadia day cab equipped with a Cummins ISX 15L diesel engine will be available for demo at Aemetis's Keyes, California renewable fuel production facility for the foreseeable future.

Matt Van Steenwyk, APG's Chairman noted, "We strongly believe our ability to utilize renewable natural gas, and renewable diesel represents a very compelling cost-effective carbon reduction solution available today for all fleets, especially those in California where approximately 98% of their heavy-duty fleets are diesel powered." Mr. Van Steenwyk added, "APG's V6000 dual fuel solution, displacing 50-60% of diesel consumption with RNG from dairy manure has been shown to produce an estimated Carbon Intensity ("CI") score of between -104 to -145 gC02e/MJ and avoid between 500 to 610 metric tons of CO2 per year per vehicle. When replacing fossil diesel fuel with renewable diesel the CI scores increase to between approximately -137 and -171 or up to 700 metric tons of avoided CO2, per vehicle per year. With an estimated 420,000 Class 8 trucks registered in California and countless more transiting California, the potential annual reduction is in the millions of metric tons of CO2 based on full adoption."

Chuck Coppa, APG's CEO/CFO stated, "APG's dual fuel solution is available for virtually any diesel engine with our heavy-duty truck conversion cost at approximately $10,000 plus the cost of a natural gas tank which would be determined based on route structure and refueling availability." Mr. Coppa added, "With estimated price spreads today between diesel and natural gas in the $2.00 to $3.00 range, an operator consuming 1,500 gallons of diesel fuel per month on long haul routes operating at a 50% displacement rate could generate an estimated net fuel savings per month of between $1,500 to $2,250.

Eric McAfee, Aemetis's Chairman and CEO stated, "We envision that APG's Dual Fuel Solution running Aemetis's RNG and ultimately renewable diesel can become an important transition step in California's evolution to cleaner air and their ultimate goal of achieving net-zero carbon emissions for the transportation industry. We believe APG's low-cost conversion price point in conjunction with our growing RNG volumes will help drive the adoption of reduced cost and lower emission fuels."
