What Clean Air Power does
Clean Air Power is a privately-held industrial technology company founded in 1991 that has pioneered Dual-Fuel™ propulsion systems enabling vehicles to operate on natural gas, typically in combination with conventional diesel or gasoline. The company's core product is its proprietary Dual-Fuel™ technology platform, which targets the heavy-duty vehicle, commercial fleet, and OEM segments seeking lower-emission, natural-gas-based powertrain solutions as an alternative to pure diesel operation. The company is headquartered in San Diego, United States, and operates with a small team of 11-50 employees. Leadership consists of John Pettitt, who serves as President, CEO, and Board Member.
The company's go-to-market model has historically centered on licensing or selling its Dual-Fuel™ technology to vehicle OEMs, fleet operators, and retrofit integrators in the natural gas vehicle ecosystem. Clean Air Power has raised approximately $15.16M in disclosed funding across three rounds between 2012 and 2014, with Parkwalk Advisors serving as the sole or lead investor in each transaction. No public pricing model, customer list, or revenue disclosures are available in the source data. The company's website (cleanairpower.com) currently displays only a verification/loading page, providing no substantive product, customer, or operating information. There is a notable data inconsistency: the firmographic HQ is San Diego, yet the sole disclosed institutional backer is a UK-focused fund, which may reflect dual-jurisdictional operations, a prior corporate restructuring, or a data quality issue in aggregated sources.

Clean Air Power competitors and assessment
Company assessmentDirect peers
- Westport Fuel Systems: Westport Fuel Systems (formerly Westport Innovations) developed high-pressure direct-injection natural gas and dual-fuel engine systems for heavy-duty trucks — the closest direct competitor to Clean Air Power's Dual-Fuel™ technology across both product architecture and target fleet customers.
- Scania: Scania offers factory-built natural gas and biogas-powered trucks and buses in Europe, making it both a competitor to dual-fuel aftermarket conversion and a potential OEM partner for Clean Air Power's technology on commercial vehicle platforms.
- IVECO: IVECO has one of the most extensive compressed and liquefied natural gas commercial vehicle lineups (Daily, Stralis NP), directly competing for the same fleet customers Clean Air Power targets with dual-fuel retrofits and conversions.
Broad incumbents
- Cummins Westport (Cummins joint venture): The Cummins Westport joint venture produces the L-series natural gas engines (spark-ignited) for transit buses and refuse trucks, competing head-to-head with Clean Air Power's dual-fuel approach in fleet applications while leveraging Cummins' massive OEM footprint.
- Volvo Trucks: Volvo Trucks produces both natural gas-powered FH/FL series trucks and BEV models, addressing the same heavy-duty fleet decarbonization problem that Clean Air Power's dual-fuel system targets, though Volvo's solution mix is broader and OEM-integrated.
- Cummins Inc. Cummins is the dominant heavy-duty engine OEM with ongoing investment in both natural gas and hydrogen powertrains. It is a potential acquirer of Clean Air Power's dual-fuel IP and simultaneously a competitive threat if it chooses to expand its own dual-fuel development.
Others
- Clean Energy Fuels: Clean Energy Fuels operates the largest U.S. network of natural gas refueling stations for heavy-duty trucks. It is the ecosystem enabler that determines whether dual-fuel vehicles are commercially viable, making it a complementary (rather than directly competitive) peer to Clean Air Power.
- Chart Industries: Chart Industries supplies cryogenic and gas-handling equipment used in LNG/CNG vehicle fuel systems (regasification, storage). It is an adjacent supplier whose hardware complements Clean Air Power's dual-fuel integration work on heavy-duty platforms.
Emerging players
- Ballard Power Systems: Ballard is the leading PEM fuel cell manufacturer targeting heavy-duty trucks, transit buses, and marine vessels — competing for the same emission-reduction budget as dual-fuel technology but positioned as a zero-emission alternative rather than a bridge fuel.
- Plug Power: Plug Power's ProGen fuel cell engines target Class 1–8 trucks, forklifts, and stationary power, representing the long-term zero-emission endpoint that may compress the relevance of Clean Air Power's natural gas dual-fuel portfolio.
