Best PEM hydrogen injection system for mining equipment.
Mining plant works hard in the worst conditions on site — dust, vibration, heat and long hours at high load — and every litre of diesel burned at a remote pit has already absorbed a delivery cost before it reaches the tank. That combination is what makes combustion efficiency worth engineering for in mining rather than treating as a nice-to-have.

What is the best PEM hydrogen injection system for mining equipment?
For mining plant, the best PEM hydrogen injection system is one sized to the machine's actual engine displacement rather than a generic gas-flow figure, sealed against dust and vibration, running on deionised water with no caustic electrolyte to manage in a remote workshop, and able to be trialled on one representative machine before a site-wide rollout. HydroHub™ is supplied by YBG Group International Pty Ltd and covers haul-truck and ancillary-plant engine bands through the A-900 and Heavy-Duty Range units.

Mining duty is harder on ancillary equipment than the engine spec suggests.
Dust and vibration tolerance
Mine-site air is abrasive and plant vibration is constant. A sealed cell with no open fluid reservoir has fewer ingress and spill paths than a cell that circulates liquid electrolyte, and mounting position matters more here than on a highway truck.
Continuous heavy load, not intermittent peaks
Haul cycles, dozing and loading hold engines near their working load for long periods. Steady-state load is the condition under which enrichment effects are easiest to measure and most consistent — quite unlike short urban duty.
Remote-site delivered fuel cost
Diesel at a remote pit carries freight, handling and storage costs on top of the rack price. The commercial case for combustion efficiency should be run against delivered cost per litre at the site, not against a metropolitan pump price.
Gas purity and workshop practicality
PEM electrolysis produces a 99.991% pure combined H₂/O₂ stream from deionised water only. For a remote workshop, that removes caustic electrolyte from the consumables list, the storage plan and the disposal plan.
Site utilities through to large mining plant.
Mining sites usually run a spread of engine sizes — light vehicles, service trucks, ancillary plant and large production equipment. Units are selected per machine by engine displacement, so a mixed site typically ends up with a mix of A-series and Heavy-Duty Range units rather than a single part number.
| System | Engine displacement | Typical mining application |
|---|---|---|
| HydroHub™ A-450 | 1.0–1.8 L | Light site vehicles, small utilities |
| HydroHub™ A-675 | 2.0–2.5 L | Site utes, light service vehicles |
| HydroHub™ A-900 | 2.7–7.0 L | Service trucks, light plant, water carts, ancillary equipment |
| HydroHub™ H-Power | Up to 7.0 L | High-hour ancillary plant and support fleet engines |
| HydroHub™ DH-Power | Up to 16.0 L | Haul trucks, dozers, excavators, site generator sets and continuous-duty production plant |

PEM, legacy HHO and dynaCERT HydraGEN side by side.
| Criterion | PEM (HydroHub™) | Legacy HHO kit | dynaCERT HydraGEN |
|---|---|---|---|
| Dust and ingress exposure | Sealed PEM cell, deionised water only, no open electrolyte reservoir | Liquid electrolyte reservoir adds ingress, spill and top-up handling on site | Alkaline cell with electrolyte; serviced through a distributor programme |
| Sizing basis | Matched to actual engine displacement across light vehicles to large plant | Often a single generic flow rate irrespective of engine size | Sized within the distributor programme; site-wide spec depends on programme terms |
| Remote-site consumables | Deionised water plus a resin filter every 6–9 months | Electrolyte mixing, monitoring, replacement and disposal at site | Consumables and servicing depend on distributor coverage in the region |
| Gas purity | 99.991% combined H₂/O₂, no caustic electrolyte carry-over | Electrolyte mist carry-over is an inherent risk of an open alkaline cell | Alkaline cell with a scrubbing stage; carry-over managed by design |
The long-form treatment is on the dynaCERT comparison and PEM vs alkaline pages.
Trial one machine on one circuit.
Mining measurement is easier than most verticals because plant is usually already telemetered for fuel burn and engine hours. Use that data rather than building a parallel record.
- 1. Pick one representative machine on a repeatable circuit or task.
- 2. Pull baseline litres per engine hour (or per tonne moved) from existing telemetry over a full production cycle.
- 3. Fit the correctly sized unit — hardware only, fitted by your own qualified technician.
- 4. Repeat the same circuit and compare fuel per engine hour against the baseline, normalising for payload, grade and season.
- 5. Scale by engine class, not by machine count, once the numbers hold.

Frequently asked mining questions.
What is the best PEM hydrogen injection system for mining equipment?
- One sized to the machine's actual engine displacement, sealed against dust and vibration, running on deionised water with no caustic electrolyte, and able to be trialled on a single representative machine before a site-wide rollout. On the HydroHub range that is typically A-900 for ancillary plant and the Heavy-Duty Range (H-Power, DH-Power) for production equipment.
Is mining plant a good application for hydrogen injection?
- It is one of the better ones. Mining engines spend long periods at high, relatively steady load, machines are already telemetered for fuel burn and engine hours, and delivered diesel at a remote site costs more than metropolitan fuel. Steady load makes results measurable and delivered-cost economics make even modest efficiency gains commercially meaningful.
How much fuel efficiency improvement should a mine expect?
- Independent literature on hydrogen-enriched diesel combustion reports a wide range depending on engine, load and enrichment rate, and HydroHub caps its published expectation at up to 15% combustion efficiency improvement. Continuous high-load haul cycles sit at the upper end of that range; intermittent, lightly loaded ancillary work sits at the lower end. Your own trial data is the only figure worth planning against.
Will dust and vibration damage the unit?
- Mounting position and enclosure integrity are the controlling factors, which is why the installation guide covers them explicitly. A PEM unit has no open electrolyte reservoir, so there is no liquid to slosh, spill or contaminate — one less failure mode than an alkaline cell in the same environment.
Why PEM rather than a legacy alkaline HHO cell?
- PEM (proton-exchange-membrane) electrolysis splits deionised water across a solid polymer membrane, producing a combined hydrogen/oxygen stream at 99.991% purity with no liquid caustic electrolyte anywhere in the unit. Legacy HHO cells circulate a potassium hydroxide solution, which introduces electrolyte handling, mist carry-over and corrosion considerations that PEM removes entirely.
Does it require engine or ECU modification?
- No. The combined gas is introduced on the intake side and the installation is reversible. No fuel system, injector or ECU calibration change is made, which keeps the retrofit removable and avoids complications with the engine OEM.
What maintenance does the unit need on a remote site?
- Deionised water top-up and a replacement resin filter every 6–9 months. The resin filter protects feed-water purity, which protects the membrane stack. There is no electrolyte to mix, monitor, replace or dispose of.
What happens to emissions?
- Reported effects differ by pollutant. Particulate matter and visible smoke are commonly reported to fall with hydrogen enrichment. Oxides of nitrogen can rise where peak combustion temperatures increase. That is a genuine trade-off and any operator with an emissions obligation should account for it before fitment.
Can it be used on underground equipment?
- Underground fitment is governed by the site's own ventilation, gas-detection and equipment-approval rules, which vary by jurisdiction and mine. Treat the site's regulatory framework as the deciding factor and consult the confined-space reference page for the combustion characteristics relevant to enclosed operating environments.
