HydroHub™ PEM hydrogen systems by industry and duty cycle.
This is the index for every application vertical we cover. Each page below is a full technical page in its own right: what makes that application's engines and duty cycle distinct, which HydroHub unit fits, the published evidence that actually applies, and a measured trial protocol. Start with the vertical closest to your duty cycle — not just to your industry name.
Vehicle compatibility
Suitable for diesel 4×4 fleet vehicles, compatible with mining and off-road transport, and ideal for utes, vans, and 4WD fleet vehicles.
Compatibility statement only. It describes vehicle categories the hardware can be fitted to and makes no claim about performance, fuel use, emissions, mechanical outcomes, roadworthiness certification or mining-regulation compliance.
01 · Application verticals
11 industry verticals, each with its own duty-cycle analysis.
Unit selection is decided by engine displacement, between roughly 1.4 and 16.0 litres. Everything else — mounting, protection, servicing interval and how you measure the result — is decided by the application. That is what these pages cover.
01
Mining fleets →
Haul trucks, articulated dumpers, production dozers, loaders, drill rigs and camp gensets. Dust, pit heat and remote servicing decide as much as displacement does, and carted fuel changes what a percentage is worth.
mining fleet fuel efficiency
02
Marine →
Workboats, charter and dive vessels, ferries and ship's service gensets. Nothing is stored aboard — gas is made on demand — which is normally a surveyor's first question.
marine diesel fuel efficiency
03
Commercial fishing →
Extended offshore duty: long transits, trawl and haul cycles, deck hydraulics and reefer drives. Bunkered fuel cost and days-at-sea reliability drive the arithmetic.
fishing vessel fuel efficiency
04
Agriculture →
Tractors, headers, sprayers, farm trucks and irrigation pump sets. Seasonal idle periods, on-farm water quality and distance from a dealer shape the specification.
tractor fuel efficiency
05
Rail & locomotive →
Two duty profiles in one sector: mainline locomotives on long steady high-load hours, and shunting, yard-switching and rail-maintenance plant on stop-start duty with heavy idle.
diesel locomotive fuel efficiency
06
Drilling rigs →
Rig power packs, mud pumps, air compressors and pad plant running long steady-state hours where fuel is trucked in and every litre carries a freight cost.
drilling rig fuel consumption
07
Public transport & bus →
Urban route buses, coaches and midibuses. Stop-start duty with high idle fractions, depot-based servicing and public-facing smoke visibility all matter here.
bus fleet fuel efficiency
08
Waste & refuse collection →
Compactor and side-loader trucks: hundreds of stops per shift, heavy idle and stationary PTO load — the duty profile the published literature reports most room on.
garbage truck fuel efficiency
09
Confined space & underground →
Underground headings, tunnels and enclosed workshops where diesel particulate and ventilation load are the operating constraint before fuel cost is.
underground mining diesel particulate
10
Generator sets →
Stationary diesel gensets on continuous and prime duty from 100–500 kVA — remote camps, telecom sites and standby plant fed from the set's own starting battery.
diesel generator fuel efficiency
11
Generator-set classes →
Camp, prime, standby, rental, telecom, irrigation and ship's service sets compared class by class, with the load factor each one actually runs at.
prime vs standby genset
02 · Shared evidence base
The pages every vertical draws on, rather than re-deriving.
The mechanism, the technology category and the published literature do not change between industries — so they live in one place and each vertical links to them. Read these once and the vertical pages become shorter and more useful.
Technical pillars
Does it actually work? Evidence review →
The published literature, the FTC/EPA history and how we frame claims under Australian Consumer Law.
PEM vs alkaline →
Membrane on deionised water versus caustic KOH: gas purity, servicing burden and lifetime cost.
How it works — mechanism →
The gas path from water to cylinder, and the established combustion physics behind it.
Category distinction →
Combustion enhancement versus H2ICE, fuel cells and chemical generation — what this is not.
Usage cases
Idle & part-load duty cycles →
Where the literature reports the most room: high idle, low load, stop-start work.
Remote-site fuel logistics cost →
Landed cost versus pump price, and why the same honest percentage moves more money.
Visible smoke reduction →
Smoke-opacity findings per study, with the NOx trade-off disclosed up front.
Hydrogen with biodiesel blends →
Per-study findings on blended fuels, including where results do not hold.

FAQ
Applications: common questions.
Which industries do HydroHub PEM systems apply to?
- Any operation running diesel engines between roughly 1.4 and 16.0 litres displacement on sustained duty. In practice that means mining fleets, marine and commercial fishing vessels, agriculture, rail, drilling rigs, route buses and coaches, waste and refuse collection, confined-space and underground plant, stationary generator sets, and general truck and mixed-fleet transport. Each has its own application page covering duty cycle, unit selection and measurement.
How do I know which application page applies to my fleet?
- Pick the page that matches your duty cycle, not just your industry name. A mine site running haul trucks, camp gensets and light vehicles will use three pages: mining, generator sets and transport. Duty cycle — how much idle, how much steady load, how many hours — decides both the unit and how you measure the result.
Do the different verticals use different hardware?
- No. The same PEM platform is used across every application; only the unit size and mounting arrangement change. Displacement decides the unit, and the operating environment decides where the cabinet goes and how it is protected.
Where does the evidence behind each application page come from?
- Every vertical page draws on the same shared evidence base rather than deriving its own. The four technical pillar pages cover the mechanism, the PEM versus alkaline distinction, the technology category and the published-literature review; the four usage-case pages cover idle and part-load duty, remote-site fuel logistics cost, visible smoke and biodiesel blends. Vertical pages link to whichever of those actually apply.
Can I trial a system on one machine before committing a fleet?
- Yes, and that is the approach every application page recommends. Instrument one representative asset per class, baseline it over a repeatable duty cycle, fit one unit, then compare over the same duty. Systems are sold outright at a published price, so a single-unit trial does not require a quote process.
