Hydrogen Fuel Efficiency Systems for Diesel & Petrol Engines
Pure-water PEM hydrogen injection, fitted to the engine you already own. One vehicle or a whole fleet — 1.0 L campervans and utes through to 16.0 L prime movers. No caustic electrolyte, no onboard hydrogen storage, no fuel-system or ECU modification, and fully reversible fitment that stays compatible with existing exhaust after-treatment.
Car, ute, 4WD or campervan
The HydroHub™ A-450, A-675 and A-900 suit 1.0–7.0 L petrol and diesel engines and mount in the engine bay or behind the cab on the existing 12 or 24 V supply. Priced, in stock and delivered to your door.
Trucks, mining, marine & gensets
H-Power and DH-Power cover diesel and gas engines to 16.0 L (500–600 kW) in industrial cabinets — line-haul transport, mining, marine and high-value stationary power, with fleet quoting and engineering support.
On the evidence: peer-reviewed engine testing of small-fraction hydrogen and oxygen addition reports modest, conditional gains in brake thermal efficiency — single digits to low or mid teens, with some conditions showing no measurable benefit. We publish that attributed literature and our measurement method rather than a fleet-wide performance percentage of our own. Read the evidence review
Engineered hydrogen injection technology — built, tested, priced, and delivered. Not a pitch, not a raise. A product.
Find the Right System for Your Engine
From passenger vehicles to heavy trucks, marine vessels, commercial fishing fleets, agricultural equipment, and stationary power — one engineering platform, sized to your engine.
Select your vehicle or equipment type to see the recommended PEM Hydrogen Combustion Enhancement System.
Cards 3 and 4 overlap on displacement. The differentiator is duty cycle: the A-900 is the compact unit for passenger and light-use engines, while H-Power and D-900 are heavy-duty kits rated for continuous commercial operation.

- Buy now, trial it yourself. Published pricing, direct purchase, no sales process required to find out what it costs or to get a unit on your own equipment. See the price, buy one unit, trial it on your own fleet — no sales calls, no minimum order, no waiting on a quote. Field evaluation on your own duty cycle remains the only valid basis for a commercial decision; buying a single unit makes that evaluation possible, it does not promise a result.
Performance depends on engine condition, duty cycle, fuel quality and operating environment, and should be established by measurement on your own equipment. See field results and fleet trials.
