Frequently asked questions

No. The system generates a hydrogen-oxygen gas mixture on demand through PEM electrolysis using purified water. Gas is produced only while the system is operating and is introduced directly into the engine air intake. There are no compressed hydrogen cylinders and no high-pressure storage on board.

The system produces a hydrogen-oxygen gas mixture generated directly from water through PEM electrolysis. The gases are produced in the natural electrolysis ratio of approximately 2 parts hydrogen to 1 part oxygen — the stoichiometric ratio associated with water decomposition and recombination. The resulting hydrogen-oxygen mixture is introduced into the engine air intake upstream of combustion. Unlike compressed hydrogen storage systems, the gas is generated on demand during operation and is not stored within the system. The precise combustion response depends on engine design, operating conditions, fuel quality and installation configuration.

No. The system uses a solid polymer electrolyte (PEM) — no liquid KOH, NaOH or other caustic is involved. The PEM stack produces clean hydrogen and oxygen with no ozone and no caustic carry-over — unlike legacy alkaline (KOH/NaOH) electrolysers.

The system is engineered around safety-by-design principles: ▸ No onboard storage — gas is generated and consumed continuously while the engine runs. ▸ Low instantaneous flow rates — only the gas needed at that moment is produced. ▸ Automatic shutdown — production stops the moment the engine stops. ▸ Integrated alarms — water-shortage, over-temperature and overload alarms each trigger an automatic shutdown. Because there is no high-pressure storage and the gas is consumed as it is generated, the residual inventory in the system at any moment is very small.

No. The system injects gas into the air intake upstream of the engine. The fuel system, ECU and after-treatment remain unchanged.

The system is designed for compatibility with modern after-treatment (DPF, SCR, EGR, AdBlue): gas is introduced upstream of the intake as a small fraction of total airflow and the fuel system is untouched. Compatibility should be confirmed per engine family during the evaluation phase.

Manufacturer test data reports fuel-consumption reductions in selected vehicle trials. Actual results depend on engine condition, load profile, installation quality, fuel type, duty cycle and operating conditions. No fuel-saving guarantee is expressed or implied — performance must be validated by controlled field evaluation under real operating conditions.

Introducing a small flow of mixed hydrogen and oxygen into the intake air does not "add fuel" in any meaningful energy sense — the energy contribution is negligible at the flow rates these systems run at. The mechanism is different. Hydrogen has a laminar flame speed several times that of gasoline or diesel vapour, and a much wider flammability range. A small hydrogen fraction in the intake charge acts as a combustion accelerant: ignition propagates faster across the chamber, end-gas burns more completely before the exhaust valve opens, and the fraction of fuel that would otherwise leave the cylinder unburnt or partially oxidised is reduced.

Use the Fuel Cost Scenario Calculator to model economics for your vehicle, fleet or generator set at an assumed fuel-reduction you choose. Enter your fuel price, annual distance or operating hours, and a percentage reduction to see projected cost and litres saved over a year. This is scenario modelling — not a prediction or guarantee.

The system is non-invasive — hydrogen-oxygen mixed gas is introduced at the air intake only. The OEM fuel system and ECU are not modified, and installation is fully reversible. Operators should consult their engine OEM where warranty is a concern.

Installation may be performed by a competent DIY installer or a qualified automotive electrician. Mounting brackets, wiring harnesses and intake fittings are supplied with each unit. ▸ Mount in the boot/trunk of passenger vehicles or behind the cab in utility vehicles using a vibration-isolated mounting bracket. ▸ Connect to a switched 12V or 24V DC power supply via the supplied inline fuse and relay. ▸ Route the 8 mm gas outlet line to an air-intake injection point downstream of the Mass Air Flow (MAF) sensor. ▸ Fill the system using purified or deionised water only (TDS ≤ 5 µS/cm). ▸ Adjust and verify vibration-sensor sensitivity to suit the vehicle, generator or engine duty cycle. ▸ Installation is non-destructive and fully reversible, requiring no modification to the engine itself.

The system is designed for automatic operation and requires no daily intervention beyond maintaining the correct water level. Startup ▸ Verify the reservoir contains purified or deionised water (TDS ≤ 5 µS/cm). ▸ Ensure all electrical and intake connections are secure. ▸ Start the vehicle, generator or engine normally. ▸ The vibration-sensor control system detects engine operation and automatically activates the PEM electrolysis system. ▸ Hydrogen-oxygen gas production begins automatically and is introduced into the engine air intake. Shutdown ▸ Switch off the vehicle, generator or engine normally. ▸ The vibration-sensor control system detects the cessation of engine operation. ▸ Gas production automatically stops. ▸ The system enters standby mode until the next engine start. No compressed gas cylinders, manual gas valves or special startup procedures are required. The system is designed to operate only while the engine is running and to shut down automatically when engine operation ceases.

No. The system uses an adjustable vibration-sensor control system that detects engine operation and automatically starts and stops hydrogen-oxygen gas production. Once installed and configured, normal operation requires only periodic inspection and replenishment of purified or deionised water as required. The system is intended to operate automatically in line with the vehicle or generator duty cycle. The accompanying video demonstrates the automatic operating sequence.

The system is water-based and must be protected from freezing. Recommended operating temperature range is approximately +5 °C to +45 °C ambient. For sub-zero or remote cold-climate sites: ▸ Mount the unit in a heated or insulated enclosure that holds internal temperature above freezing, or ▸ Drain the reservoir and feed lines when the unit will be idle in freezing conditions. Do NOT add antifreeze, glycol, methanol or any other freeze-point depressant to the feed water. These additives contaminate and destroy the PEM membrane and will void warranty. Feed water must remain purified / deionised only (TDS ≤ 5 µS/cm).

Continuous draw is approximately 80–170 W at 12 V or 24 V DC depending on model and output setting. This is negligible against a typical vehicle alternator (1–3 kW) or genset charging circuit. The unit includes built-in under-voltage and over-voltage protection that shuts the electrolyser down before battery state-of-charge is affected, so the system cannot flatten the starter battery during prolonged idle.

Refill with purified or deionised water (TDS ≤ 5 µS/cm) as required — the integrated sight glass and water-shortage alarm indicate when refill is due. The PEM stack itself is sealed and does not require electrolyte management.

Electrolysis of 1 litre of water yields approximately 1,866 litres of hydrogen-oxygen gas. Water consumption is therefore very low relative to gas output. Indicative continuous-operation runtime per 1 L of feed water, at maximum output: ▸ 12 L/hr unit — ~6.4 ml/hr → ~156 hours per litre ▸ 24 L/hr unit — ~12.9 ml/hr → ~78 hours per litre ▸ 36 L/hr unit — ~19.3 ml/hr → ~52 hours per litre ▸ 54 L/hr unit — ~28.9 ml/hr → ~34 hours per litre Real-world consumption is typically lower than these figures because the unit modulates output to the duty cycle rather than running flat-out continuously.

The resin filter polishes the feed water before it reaches the PEM stack. Water standing in the onboard tank can pick up dissolved ions and trace contaminants over time; the ion-exchange resin removes these so only high-purity, low-conductivity water enters the electrolyser. This protects the membrane and electrodes, maintains stable cell voltage and gas quality, and preserves stack life. The resin filter is replaced annually as part of routine service.

Each unit ships with a 12-month manufacturer warranty against defects in materials and workmanship, subject to correct installation, use of compliant feed water (purified or deionised, TDS ≤ 5 µS/cm), and adherence to the stated operating envelope.
