Powering Class 8 Trucks With Dairy RNG

American Power Group Corporation (APG), a US-based dual fuel diesel engine conversion technology company, announced that its vehicular dual fuel solution can generate significantly low carbon emissions when displacing diesel fuel with dairy manure renewable natural gas (RNG). APG said that it delivers impressive low carbon fueling results on existing Class 8 diesel engines when utilizing its vehicular dual fuel solution and displacing 50% to 60% of fossil diesel consumption with RNG from dairy manure. The estimated RNG dual fuel carbon intensity (CI) score was between -104 to -145 gC02e/MJ and would avoid between an estimated 551 to 672 tons (500 to 610 tonnes) of carbon dioxide (CO₂) per year per vehicle.

APG utilized EcoEngineers, a consulting, auditing and advisory firm exclusively focused on the energy transition and decarbonization which was recently acquired by global assurance partner LRQA. EcoEngineers reviewed APG’s information and calculations, including calculated CI score utilizing APG’s vehicular dual fuel solution and multiple renewable natural gas sources and determined the methodology was reasonable and accurate.

“There are approximately 2 million late-model Class 8 diesel trucks operating in the US,” said Chuck Coppa, APG’s chief executive officer and chief financial officer. “Assuming an estimated CO₂ reduction of 500 tonnes per truck per year utilizing our vehicular dual fuel solution and dairy RNG, the potential positive domestic impact on the environment would be in the range of 1 billion tonnes of CO₂ reduction per year without the need for significant alternative energy infrastructure investments. Using low-carbon or negative-carbon RNG can also significantly lower diesel-related criteria pollutants and improve a fleet’s carbon intensity footprint with no loss of heavy-duty engine power and torque. Utilizing APG’s vehicular dual fuel solution, fleet owners can avoid spending over US$400,000 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. According to the American Trucking Association, 95.8% of all carriers operate 10 or less trucks and 99.7% operate 100 or less trucks so we believe most are either just hesitant of change or don’t have the financial resources to completely swap out their entire diesel fleet for cleaner burning vehicles which makes our vehicular dual fuel solution the ideal transition technology upgrade. We continue to believe there is no one silver bullet solution available to reduce heavy-duty diesel truck emissions but APG’s vehicular dual fuel solution is one of the readily.”
