What American Power Group does
American Power Group, Inc. (APG; OTCQB: APGI) is a US-based, publicly traded dual fuel technology company headquartered in Algona, Iowa, that develops and commercializes EPA-approved aftermarket conversion systems enabling heavy-duty diesel engines to operate simultaneously on diesel and natural gas. The company has been operating under its current dual fuel technology focus since the late 1990s and is led by CEO/CFO Charles E. Coppa (with the company since March 1998, CEO since June 2017) and Chairman Matt Van Steenwyk (director since July 2015, chairman since July 2021).
APG's product line consists of two core systems: the V6000 vehicular dual fuel system for over-the-road and return-to-base diesel truck fleets, and the S4000 stationary dual fuel system for power generation, emergency backup, data center, and oil and gas applications. The underlying technology meters natural gas (CNG, RNG, LNG, or conditioned wellhead gas) into the diesel engine's induction system using a negative-pressure approach that works in concert with the OEM engine governor, governed by APG's proprietary Engine Control Module (ECM) that optimizes fuel ratios in real time. The hardware mounts externally without modifying the base engine, preserving OEM warranties under the Magnuson-Moss Warranty Act and achieving 40-55% average diesel displacement (up to 75% peak) with reported fleet fuel savings of 25-30% net. APG holds EPA approvals on over 500 on-road engine families across 6 OEM platforms, CARB Executive Orders for select Cummins, Detroit Diesel and Volvo/Mack engines, and EPA Memo 1A compliance for 12+ off-road engine models from CAT, Cummins, Detroit Diesel and MTU.
The company operates a quote-based, consultative sales model selling systems directly to fleet operators and industrial customers while distributing through a Certified Dealer/Installer Network that handles installation, warranty service, and hardware reactivation. Revenue streams include one-time system sales, tank package facilitation, and ongoing usage-based fuel savings for customers (with planned financing partnerships). Target customer segments span oil and gas drilling operations, heavy-duty diesel trucking fleets, distributed power generation, emergency backup systems, data centers, and natural gas fuel providers. Operational scale is small, with 1-10 employees per firmographic disclosure, and named enterprise customers include Stewart Logistics (a FedEx Ground contractor), Sapphire Gas Solutions, and major oil and gas operators.

Revenue model
- Dual Fuel System Sales: APG sells its dual fuel conversion systems (V6000 for vehicles, S4000 for stationary applications) along with associated hardware components. The company uses a certified dealer/installer network for installation. Pricing is quote-based following fleet and cost analysis.
- Natural Gas Tank Packages: While APG does not manufacture tanks, the company facilitates tank package sales as part of the conversion. They provide recommendations for tank options based on application, demographics, topography, and fueling options.
- Fuel Cost Savings: Customers realize ongoing fuel cost savings (10-40% annually) from displaced diesel consumption. Fleet owners achieve ROI through fuel savings that offset initial conversion costs over time.
- Financing Services: APG is working with financing entities to potentially provide financing for both the Dual Fuel System and tank packages, enabling broader customer access.

American Power Group product offering
Product offeringCore offering
American Power Group (APG) designs, commercializes, and supports EPA- and CARB-approved aftermarket dual fuel conversion systems that enable existing high-horsepower diesel engines to operate simultaneously on diesel and natural gas (CNG, RNG, LNG, or conditioned wellhead gas). Its two flagship products are the V6000 vehicular system (for over-the-road trucks and return-to-base diesel fleets) and the S4000 stationary system (for power generation, emergency backup, data centers, and oil and gas applications), with installations performed by a certified dealer/installer network.
Product overview
American Power Group (APG) offers two core dual fuel conversion systems: the V6000 for vehicular applications (over-the-road trucks and diesel vehicles) and the S4000 for stationary applications (power generation, emergency backup, data centers, and oil/gas operations). Both systems are EPA-approved aftermarket upgrades that convert existing diesel engines to run on a mixture of diesel and natural gas (CNG, RNG, LNG, or conditioned wellhead gas), displacing 40-65% of diesel fuel with natural gas while maintaining original engine power, torque, and warranties.

American Power Group competitors and assessment
Company assessmentDirect peers
- Westport Fuel Systems: Westport develops natural gas engine and fuel system technology for heavy-duty and industrial applications. It is the most direct peer to APG in delivering natural gas as a substitute or supplement for diesel in on-road and stationary high-horsepower engines.
- Agility Fuel Solutions: Agility designs and manufactures CNG and RNG fuel systems and storage for heavy-duty trucks and buses. It is a direct peer in the natural-gas-for-diesel displacement value chain and serves overlapping OEM and fleet customers.
Broad incumbents
- Cummins Westport: Joint venture between Cummins and Westport producing OEM factory-built natural gas engines (LNG/CNG). It competes with APG by offering warranted, factory-integrated natural gas propulsion rather than an aftermarket retrofit.
- Clean Energy Fuels: Clean Energy operates the largest network of natural gas vehicle refueling stations in North America and downstream RNG supply. It overlaps APG on the demand side by directing fleet customers to natural gas solutions and is a complementary/competing part of the dual fuel ecosystem.
- Volvo Trucks: Volvo Trucks is a named OEM platform for APG's CARB-approved dual fuel retrofits. Volvo is also expanding its own zero-emission truck portfolio, positioning it as both an enabler (approved engine families) and competitor (factory alt-fuel trucks) to APG.
- Daimler Truck (Freightliner / Mercedes-Benz Trucks): Daimler Truck is one of the major heavy-duty OEMs whose engines APG retrofits under CARB/EPA approvals. Daimler also offers its own natural gas and electric truck options, making it both a partner and competitive threat to APG's aftermarket V6000 business.
Emerging players
- Xos Trucks: Xos produces Class 6-8 battery-electric trucks and chassis purpose-built for fleets. It overlaps APG's heavy-duty fleet customer base, competing for the same retrofit-vs-replace decision with a dedicated BEV proposition.
- Lightning eMotors: Lightning eMotors specializes in fleet electrification — converting existing vans, trucks, and shuttle buses to battery-electric powertrains. Its fleet conversion business model and target customer (commercial fleet operators) directly overlap APG's V6000 channel, though it competes via BEV rather than dual fuel.
Others
- Ballard Power Systems: Ballard develops PEM fuel cell stacks for heavy-duty mobility, backup power, and stationary applications. Its stationary backup power and heavy-duty focus overlap the deployment settings for APG's S4000 system, though via a different (hydrogen) energy carrier.
- Plug Power: Plug Power delivers hydrogen fuel cell solutions for material handling and on-road mobility. It targets the same heavy-duty fleet decarbonization opportunity as APG but via a hydrogen rather than natural gas pathway, making it an adjacent competitor in the alt-fuel powertrain space.
