The litre you don't burn is worth what it cost to get there.
Fuel economics at a remote mine site, a pastoral station or a research camp are not the economics printed on a bowser. The number that matters is landed cost — what you actually paid to have a litre of diesel available at the point of use, after cartage, barging or air freight. The percentage a system might reduce consumption by does not change with remoteness. The dollars behind that percentage do.
Why does remote operation change the case for combustion enhancement?
Because the baseline cost is higher, not because the saving is bigger. The independent literature reports fuel-consumption reductions from hydrogen enrichment in a broadly single-digit to mid-teens range, and only under some duty cycles. That range is unchanged at a remote site. What changes is that each litre is valued at delivered cost rather than pump price, so the same percentage represents a larger absolute figure. We publish no headline performance percentage of our own, and we do not publish a landed-cost multiplier — both belong to your own data.
- Landed cost = product + freight + handling + losses, divided by litres that reached the tank.
- Delivered cost at remote sites can be significantly higher than bowser price; by how much is site-specific.
- The honest saving range does not increase with remoteness — only the dollar value per litre does.
- Model it with your own invoice figures in the fuel savings calculator.
Pump price is not what remote fuel costs you.
Pump price
What a litre costs at a retail or bulk supply point. It is the number most fuel-saving arithmetic on the internet uses, because it is the only number that is easy to find. For an operation that draws fuel from a nearby bowser, it is also roughly correct.
Landed (delivered) cost
What a litre costs once it is in the tank at the point of use. Product cost plus road cartage over long unsealed hauls, barge or coastal freight, air freight in the extreme cases, plus handling, demurrage, wet-season contingency and losses. For remote operations, this is the only figure that should appear in a fuel business case.
We do not publish a general landed-cost multiplier. Claims of the "three times pump price" kind are presented as facts far too often and they are not facts — they are one operation's haul, one season, one contract. Delivered cost at remote sites can be significantly higher than bowser price, and the honest way to handle that is to take the figure from your own invoices.
The multiplier sits on the cost, not on the claim.
Independent published work on hydrogen and oxyhydrogen enrichment reports fuel-consumption reductions that sit broadly in the single-digit to mid-teens percentage range on the engines and conditions tested — with results that vary widely by duty cycle and engine, and with several studies reporting little or no benefit. That is the range this whole site works within, on fuel efficiency and evidence review alike.
Remoteness does not shift that range upward by a single point. The chemistry of the cylinder does not know where the tank was filled. What remoteness does is raise the price attached to every litre in the calculation, so the same conservative percentage produces a larger dollar figure than the identical percentage would at a metropolitan depot. That is the entire economic argument on this page, and it is the only form of it we will make.
For the reverse of the same logic — duty cycles where the literature suggests the percentage itself is likely to be at the weaker end — read idle and part-load duty cycles.
The calculator has a remote-site input. This page is its explanation.
The fuel savings calculator carries a "fuel is hauled to a remote site" option with a delivered-cost multiplier you set yourself, and a reduction percentage you set yourself. Nothing in it is suggested, typical or implied by us. Enter your landed cost per litre — or your pump price and your own multiplier — along with your consumption and hours, and read the arithmetic.
Operations whose fuel arrives by truck, barge or aircraft.
Mining and resources
Haul fleets, ancillary equipment and site power at locations hundreds of kilometres from a supply point, with fuel arriving by road train and stored on site. Equipment-class detail is on the mining page.
Read moreRemote agriculture and pastoral
Stations and irrigation operations where diesel is carted in and stored in farm tanks, and where pumping and harvest windows concentrate consumption into short periods.
Read moreMarine and island operation
Vessels and shore facilities bunkering at limited ports, and island or coastal operations where fuel arrives by barge. Marine detail is on the marine page.
Read moreRemote research, camps and site power
Field stations and camp gensets running on carted fuel, where a delivery is a logistics exercise rather than a purchase. Generator selection is covered under generator sets.

No percentage beyond the honest range reported by independent studies is claimed anywhere on this page, and no percentage on this site is presented as the performance of our systems.
No landed-cost multiplier is asserted as a general fact. Delivered cost can be significantly higher than pump price; the size of that gap is yours to establish from your invoices.
No compliance, certification or emissions-test outcome is claimed or implied. Nothing here is a payback guarantee.
Findings from the studies cited on this page — including Saravanan & Nagarajan (2008) and Karagöz et al. (2016) — are set out per study, with test conditions, on visible smoke reduction and evidence review. They are laboratory results on their own engines, not statements about your fleet.
No projected, typical or expected fuel-saving figure is published. Actual results vary materially with engine condition, duty cycle, load profile, fuel quality, installation and operating conditions. A controlled field evaluation on your own equipment, with baseline data captured before installation, is required before any commercial projection.
Remote fuel economics: common questions.
Does operating at a remote site increase the percentage of fuel saved?
- No. Nothing about remoteness changes combustion. The honest range reported in the independent literature — broadly single-digit to mid-teens percentage reductions in fuel consumption, and only under some duty cycles — is exactly the same range at a remote site as it is in a metropolitan depot. What changes is the value of each litre not burnt, because the delivered cost of that litre is higher. We publish no headline performance percentage for our own systems.
What multiple of pump price should I assume for delivered fuel?
- We do not publish one, and you should be sceptical of anyone who does. Delivered cost depends on your haul distance, road or barge access, seasonal closures, tank and bunding infrastructure, demurrage, contract terms and volume. The only number worth using is the one from your own fuel invoices and freight charges. The calculator takes that figure as an input rather than assuming it for you.
How do I work out my own landed cost per litre?
- Take the total of what you actually paid to have fuel available at the point of use over a period — product cost, freight or cartage, any handling, demurrage and losses — and divide it by the litres that reached the tank. That figure, not the bowser price in the nearest town, is the number a consumption reduction should be valued against. Enter it in the calculator as your effective fuel price, or enter pump price and your own multiplier.
Does reducing consumption reduce delivery frequency?
- Arithmetically, less fuel burnt over the same period means the same tank lasts longer, so a site may re-order less often. Whether that removes a delivery in practice depends on your tank capacity, scheduling, minimum order quantities and contract structure, none of which we can see. Treat any avoided-delivery benefit as something to verify against your own logistics, not as a claim made here.
Is this a return-on-investment claim?
- No. This page explains why the economics of a given percentage reduction differ between a metropolitan and a remote operation. It does not promise a payback period. Payback depends on your measured result, your landed cost and your duty cycle, and the only responsible way to establish it is a controlled baseline on your own equipment.
Where landed fuel cost changes the arithmetic.
These verticals cart, bunker or truck their fuel, so the same honest percentage moves more money than it does at a pump.
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.
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.
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.
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.
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.
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.
