PEM Hydrogen Combustion Enhancement Systems
Vehicle-grade PEM units sized by engine displacement plus heavy-duty configurations for prime movers and generator sets. All systems use proton-exchange-membrane electrolysis with purified water — no KOH or NaOH electrolyte and no high-pressure hydrogen storage on board.
Suitable for diesel 4×4 fleet vehicles, compatible with mining and off-road transport, and ideal for utes, vans, and 4WD fleet vehicles.

11 industry guidesGenerator Sets & Heavy Equipment
Continuous-duty gensets and heavy equipment, sized to the engine's displacement band and duty cycle with no caustic electrolyte on site.
PEM hydrogen injection for generator sets & heavy equipment →Commercial Fleets
Diesel truck, bus and van fleets — displacement-based sizing, a single unit to trial before scaling, and installation documentation for consistent fitment.
PEM hydrogen injection for commercial fleets →Marine
Marine diesel engines, sized to the actual displacement band and built to tolerate humidity and salt air with no caustic electrolyte in the engine room.
PEM hydrogen injection for marine →Agriculture
Tractors, harvesters and other agricultural machinery — dust and field-vibration tolerance, with a single-machine trial across one season before rollout.
PEM hydrogen injection for agriculture →Mining
Mining plant works hard in the worst conditions on site — dust, vibration, heat and long hours at high load — on diesel that already carries a remote delivery cost.
PEM hydrogen injection for mining →Rail
Shunting locomotives, on-track maintenance machines and light-rail auxiliary power run long, repeatable duty cycles inside a maintenance regime planned to the day.
PEM hydrogen injection for rail →Public Transport / Bus
Bus fleets carry two pressures at once: fuel is one of the largest controllable line items in a route contract, and visible exhaust is noticed at every stop.
PEM hydrogen injection for public transport / bus →Waste & Refuse Collection
Hundreds of stop-start cycles a day, long idle periods with the body and compaction gear working, and very low average road speed for the engine hours accumulated.
PEM hydrogen injection for waste & refuse collection →Drilling
Drilling rigs burn diesel the way stationary power plants do — continuously, at high load, far from the nearest fuel depot.
PEM hydrogen injection for drilling →Confined Space
Underground mines, tunnelling headings and enclosed workshops size their ventilation around the diesel plant working in them, so combustion characteristics are an engineering input.
PEM hydrogen injection for confined space →Commercial Fishing
On a fishing vessel, fuel is not an overhead — it is a direct deduction from the value of the catch, settled trip by trip.
PEM hydrogen injection for commercial fishing →Free worldwide delivery. Duties & taxes included on most destinations; where pre-payment isn't permitted, the carrier collects them on arrival. 12-month manufacturer warranty. See Shipping & duties by country for the exact arrangement for your destination.
