May 8, 2025. American Power Group Corporation (APG) announced the company’s stationary/off-road dual fuel installation base has reached an estimated 25 million cumulative run hour milestone. APG’s patented Dual Fuel Technology, which converts existing diesel engines to run on up to 65% natural gas, has achieved global market leadership recognition in converting high-horsepower diesel generators and diesel pumps in a variety of key primary power and critical care emergency back-up power market applications such as:
- Oil/Gas Operations
- Manufacturing Facilities
- Hospitals
- Data/Blockchain Centers
- Frozen Good Warehousing
- Peak-Shaving Support
- Public/Govt Bldgs
- Microgrids
APG’s S4000 Dual Fuel Technology seamlessly introduces natural gas from renewable, fossil, or treated field gas into the induction system of a diesel engine, displacing up to 65% of the diesel fuel. The S4000 System does not change any of the OEM diesel engine components, maintaining base engine temperature and pressure parameters of the OEM engine. APG’s software-based Dual Fuel solution safely allows peak diesel displacement of up to 65% with typical average displacement of around 50% without any expensive additional pre-combustion or spark arresting hardware protection required at higher displacement rates. APG’s S4000 has a field performance reputation of the highest up-time and lowest total cost of ownership amongst the dual fuel industry.
Generator power ratings from 100kW to 12MW have been successfully converted to APG’s Dual Fuel Technology on a wide array of OEM diesel engine platforms including:
- Caterpillar
- Cummins
- MTU
- Detroit Diesel
- MAN B&W
- Kohler
- Perkins
- John Deere
- Komatsu
- Wartsila
- Isuzu
- Nigata
- Isuzu
- Daihtsu
APG’s Dual Fuel Technology can use renewable natural gas (RNG), compressed natural gas (CNG), liquified natural gas (LNG), captured flare-stack methane and conditioned well-head gas resulting in lower cost, lower carbon, and lower criteria pollutants. Additionally, APG’s technology remains fully compatible with eligible biodiesel blends and renewable diesel fuels further reducing a diesel engines’ carbon footprint.
Chuck Coppa, APG’s CEO/CFO stated, “This is a significant milestone for us and having the ability to reduce up to 65% of the diesel fuel with natural gas has had an enormous impact on operating costs, emissions and of course carbon footprint for operators using our technology. It’s only going to get better from all aspects as RNG becomes more prevalent and renewable diesel becomes more ubiquitous. The ability to run on essentially four sources of fuel gives operators choices without changing the overall reliability of the well proven diesel engine.”
