Fuel Cost Scenario Calculator
Model the economics for your vehicle, fleet or generator set at an assumed fuel-reduction you choose. This is scenario modelling — not a prediction. We do not suggest a figure is typical or expected.
Asking whether a hydrogen fuel saver works is a data question, not a calculator question. The measured HHO fuel savings evidence and PEM hydrogen fuel savings data we hold are published — with test conditions — in field results. For method and baselining see fuel efficiency, for the mechanism see hydrogen combustion enhancement, and for the in-cylinder side see engine performance and emissions reduction.
Does this calculator predict hydrogen fuel-saver savings?
No. It is scenario modelling: you choose the assumed fuel-reduction percentage and the tool applies it to your own litre spend and fuel price, so the output is arithmetic on your inputs rather than a prediction, a typical figure or an expected result. The measured numbers we publish — first-party YBG road trial, manufacturer road trials and published dynamometer research — are set out with their test conditions on the field results page. 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.
- Inputs: your litres, your fuel price, your assumed reduction percentage.
- Output: modelled fuel-cost scenario only — no claim about your engine or duty cycle.
- Measured trial data, with test conditions and limitations, lives on /field-results.
- A controlled field evaluation on your own vehicles or gensets is the only commercial basis we use.
Fuel Cost Scenario Calculator
Scenario modelling, not a savings prediction. You choose the assumed reduction — we never suggest a figure is typical or expected.
Remote diesel costs what it cost to deliver, not bowser price. Landed cost vs pump price →
Scenario modelling — pick a reduction to evaluate. Not a prediction.
Recommended: D-900 for this application. Payback is calculated against vehicles × system delivered price.
Results are illustrative only. Actual performance depends on engine condition, duty cycle, fuel quality, installation and operating conditions.
Field evaluation is required before any commercial decision. Fleet Trial Programme →

Calculator questions
- Is this calculator a prediction of what I will save?
- No. It is scenario modelling. You choose the assumed fuel-reduction percentage and the tool applies it to your own litre spend. We do not suggest any figure is typical or expected.
- Where does the real data come from, rather than the assumption I type in?
- The measured numbers we publish come from our first-party road trial, manufacturer trials and published dynamometer research, all set out with their test conditions on the field results page.
- Why do actual results differ from the modelled scenario?
- 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.
