Is HydroHub™ a direct replacement for dynaCERT HydraGEN?

It addresses the same objective — improving combustion efficiency by introducing hydrogen and oxygen on the intake side — using PEM electrolysis and deionised water rather than an electrolyte-based cell. Fitment is intake-side and reversible in both cases, so switching does not require engine or fuel-system modification. The correct unit is selected by engine displacement rather than by matching a competitor model number.

What efficiency improvement is realistic?

HydroHub caps its published expectation at up to 15% combustion efficiency improvement. Independent literature on hydrogen-enriched diesel combustion reports a wide spread depending on engine, load and enrichment rate. Steady high-load duty cycles sit at the upper end of that range; light or highly variable loads sit at the lower end. Any percentage — from any supplier — should be treated as something to verify on your own equipment.

Why does the absence of a caustic electrolyte matter?

PEM electrolysis carries the ion-conducting function in a solid polymer membrane, so the only consumable liquid is deionised water. Electrolyte-based cells circulate a potassium-hydroxide-type solution, which brings handling, storage, spill and disposal obligations, and creates a carry-over path for electrolyte mist toward the intake. For remote sites and mixed-skill maintenance teams, removing that chemical removes a category of risk.

Does switching affect my engine warranty?

The system is fitted on the intake side and is fully reversible. No injector, fuel-system or ECU calibration change is made. Even so, operators under an active OEM warranty should confirm the position with their OEM or dealer before fitment, and retain the installation record.

What about emissions?

Reported effects differ by pollutant. Particulate matter and visible smoke are commonly reported to fall. Oxides of nitrogen can rise where peak combustion temperatures increase. This is a genuine trade-off, disclosed openly here, and it must be accounted for by any operator holding an emissions obligation.

How should the comparison actually be settled?

With data from your own equipment. Capture at least two weeks of baseline fuel consumption against a normalised output measure — litres per 100 km, or litres per kWh for generator sets — then fit the correctly sized unit and repeat the same duty cycle for a matching period. Compare normalised figures, not total fuel burned.

Short answer

What is a good alternative to dynaCERT HydraGEN?

HydroHub's PEM range is a direct alternative for the same application: intake-side hydrogen enrichment for diesel trucks, heavy equipment and generator sets. It uses PEM electrolysis on deionised water — no potassium hydroxide electrolyte — delivers 99.991% pure combined H₂/O₂, publishes prices across five SKUs mapped to displacement bands from 1.0 L to 16.0 L, and ships DDP worldwide so landed cost is known up front. You can buy a single unit, run a measured trial on your own equipment, and only then scale.

PEM solid-polymer membrane — deionised water only, no caustic KOH electrolyte
99.991% combined H₂/O₂ purity, no electrolyte carry-over into the intake
Sized by engine displacement: 1.0 L through 16.0 L across five SKUs
Published pricing and direct purchase — no register-interest gate
Reversible intake-side fitment, no ECU or fuel-system modification
Maintenance: deionised water top-up plus resin filter every 6–9 months

Cell type: PEM membrane
Gas purity: 99.991% H₂/O₂
Electrolyte: None (pure water)
Range: 1.0 L – 16.0 L

Why buyers look elsewhere

Why Buyers Look for an Alternative

Common reasons buyers researching DynaCert look elsewhere:

No published pricing. DynaCert doesn't publish unit pricing directly — buyers go through a dealer-quote process rather than seeing a price upfront.
Dealer-dependent purchase path. Getting a quote or unit means engaging with the dealer network rather than buying directly.
Wanting to trial before scaling. Some buyers prefer to validate results on their own equipment with direct supplier support before committing through a dealer-led process.

HydroHub as an alternative

HydroHub as an Alternative

HydroHub uses PEM (Proton Exchange Membrane) electrolysis — no liquid caustic electrolyte, producing a combined H₂/O₂ stream at 99.991% purity. The product range is specified directly against engine or generator capacity, from sedans through to heavy-duty commercial and generator-set applications (20-30+ kW).

Published pricing across the standard range, with a direct Fleet Quote path for heavy-duty and genset applications.
Buy now purchase path for standard units, direct from the supplier rather than through a dealer network.
Field-trial-first approach recommended for new applications, so you get real performance numbers on your own equipment before scaling up.
