Best PEM hydrogen injection system for drilling rig engines.
Drilling rigs burn diesel the way stationary power plants do — continuously, at high load, far from the nearest fuel depot. Rig power packs, mud pumps and camp generators run around the clock while the hole is being made, and every litre arrives by road or barge at a delivered cost well above rack price.

What is the best PEM hydrogen injection system for drilling rig engines?
For drilling rigs the best PEM hydrogen injection system is one sized to each power-pack engine's displacement band, suited to continuous high-load operation, and free of caustic electrolyte so a remote camp has nothing extra to store or dispose of. HydroHub™ addresses rig engines through the Heavy-Duty Range, with A-900 covering smaller support and auxiliary engines.

Rig economics are dominated by delivered fuel and uptime.
Continuous heavy load
Rig power packs and mud pumps hold high load for long, uninterrupted periods — the same steady-state condition that makes generator sets a strong application. Steady load also produces the cleanest measurement, because there is little duty-cycle noise to filter out.
Delivered fuel cost, not rack price
Fuel trucked or barged to a remote lease carries freight, handling and storage on top of the base price. Run the commercial case against delivered cost per litre; it is often the single largest controllable cost on the pad.
Camp logistics and consumables
Anything consumable has to be freighted in and, if hazardous, freighted out. Deionised water and a resin filter every 6–9 months are trivial to plan for; a caustic electrolyte is a dangerous-goods line on both legs.
Uptime and reversibility
Rig downtime is expensive enough that any retrofit needs to be removable and to make no change to the fuel system or ECU. Intake-side fitment keeps the engine in its original configuration and lets a unit be taken off in minutes if a rig has to be demobilised.
Auxiliary engines through rig power packs.
A drilling spread usually runs several engine sizes: camp and lighting sets, support vehicles, and the main power packs. Units are selected per engine by displacement, and the heavy-duty units carry the main load.
| System | Engine displacement | Typical drilling application |
|---|---|---|
| HydroHub™ A-450 | 1.0–1.8 L | Light site vehicles |
| HydroHub™ A-675 | 2.0–2.5 L | Support utilities and crew vehicles |
| HydroHub™ A-900 | 2.7–7.0 L | Camp and lighting generator sets, service vehicles, auxiliary engines |
| HydroHub™ H-Power | Up to 7.0 L | High-hour auxiliary engines and mid-size power units |
| HydroHub™ DH-Power | Up to 16.0 L | Rig power packs, mud-pump engines, drawworks prime movers, large camp gensets |

PEM, legacy HHO and dynaCERT HydraGEN side by side.
| Criterion | PEM (HydroHub™) | Legacy HHO kit | dynaCERT HydraGEN |
|---|---|---|---|
| Continuous-duty suitability | Designed for continuous operation alongside the engine, sized by displacement | Generic kits rarely specified against continuous heavy load | Sized within the distributor programme |
| Remote logistics | Deionised water plus a resin filter every 6–9 months; no dangerous-goods consumable | Caustic electrolyte must be freighted in and disposed of correctly | Consumables and servicing depend on distributor coverage in the region |
| Gas purity | 99.991% combined H₂/O₂ from deionised water only | Electrolyte mist carry-over risk inherent to open alkaline cells | Alkaline cell with a scrubbing stage |
| Removability at demob | Intake-side, reversible; the engine returns to original configuration | Varies by kit; some require permanent plumbing changes | Fitted and removed through the distributor/installer network |
The long-form treatment is on the dynaCERT comparison and PEM vs alkaline pages.
Trial one power pack against its own sister engine.
Rigs offer something most sites cannot: several near-identical engines running the same load at the same time. That makes a side-by-side comparison far stronger than a before/after.
- 1. Identify two power-pack or genset engines of the same model carrying comparable load.
- 2. Log baseline fuel per engine hour on both across a full drilling interval.
- 3. Fit the correctly sized unit to one engine only, leaving the other as the control.
- 4. Compare the two over the following interval at equivalent load factor.
- 5. Extend across the spread by engine class once the difference is consistent.

Frequently asked drilling questions.
What is the best PEM hydrogen injection system for drilling rig engines?
- One sized to each power-pack engine's displacement band, suited to continuous high-load operation, and free of caustic electrolyte so remote camp logistics stay simple. On the HydroHub range that is DH-Power for rig power packs and mud-pump engines, with A-900 or H-Power for camp gensets and auxiliary engines.
Are drilling engines similar to generator sets for this purpose?
- Very. Both hold high, steady load for long uninterrupted periods, both are usually metered, and both sit at remote sites where delivered fuel costs more than rack price. The generator-set reference page covers the same duty profile in more depth and applies almost directly to rig power packs.
How does remote-site fuel cost change the commercial case?
- It changes the denominator. A percentage improvement in combustion efficiency is worth more per litre when the litre has already absorbed freight, handling and storage costs to reach the pad. Run the payback calculation against delivered cost per litre at the lease, not against a metropolitan price.
What happens when the rig demobilises?
- The installation is intake-side and reversible, so a unit can be removed and refitted to another engine of the same displacement band. Nothing in the fuel system, injectors or ECU calibration is changed, so the engine returns to its original configuration.
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 at a remote camp?
- 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.
