Methodology

How the estimates were built: data sources, modelling approach and validation steps.

Research approach

A market size is a claim about the world, and a claim is only as good as the route to it. Every study is built upward from units and prices — what is actually produced, sold or performed, at what it actually changes hands for — rather than from a headline figure divided downwards. Disclosed company revenue is then used to check that build, not to produce it.

Market size estimation, this report

The estimate is built upward from the number of vehicles shipped with a fuel cell powertrain fitted at the factory or through an authorized integrator, split by power band and vehicle class, multiplied by the average system selling price CDI tracks for each combination. Component-level volumes for the fuel cell stack, drive unit and hydrogen storage system are built the same way and cross-checked against each other, since a mismatch between stack shipments and completed powertrain units signals an error. The resulting total is then checked against the fuel cell and mobility segment revenue the named suppliers disclose in their own reporting; where the two disagreed, the correction was made to the underlying unit or price assumption in the bottom-up build, not by averaging in the disclosed figure.

The four stages

The same sequence runs behind every published study, whatever the industry. The order matters as much as the steps: the segment axes are fixed before any number is collected, so the model is never reshaped to fit whatever data happens to turn up.

What the build rests on, and what checks it

The two are not interchangeable. The left column produces the number; the right column tests it. When the check disagrees with the build, the answer is to find which bottom-up assumption is wrong — a unit count, a price, a take-up rate — not to split the difference between them.

The bottom-up build rests on
  • Volume actually transacted — units produced, installed, dispensed or procedures performed, counted at the level each is genuinely recorded
  • Realised pricing by tier and channel, rather than one blended average applied across the whole market
  • Take-up and frequency: how much of the addressable base buys, and how often it repeats
The build is checked against
  • Disclosed revenue of the companies serving the market, where filings separate it far enough to be usable
  • Buyer-side spending totals — capital budgets, procurement lines, or the output of the end market the product is bought against
  • Trade and customs flows, where the product crosses borders in a separately recorded form

Data sources

Published data establishes what happened. Only the people transacting in a market can say why, and what is about to change — so the two are collected separately and weighted differently.

Primary — who is interviewed
  • Commercial and product leadership at the companies that supply the market
  • Procurement and specification leads at the organisations that buy it
  • Distributors, integrators and channel partners, where the market is served indirectly
  • Regulatory and standards specialists, where approval governs what can be sold at all
Secondary — what is read
  • Company filings, annual reports and investor disclosure
  • Government statistics, customs records and regulatory registers
  • Trade association output and standards-body publications
  • Technical and peer-reviewed literature, where the market rests on a clinical or engineering claim
Primary research design, this report

Primary interviews target commercial and product-planning executives at vehicle OEMs and fuel cell system integrators, procurement leads at fleet operators piloting or operating hydrogen vehicles, and regulatory affairs contacts tracking emissions and incentive rules that shape purchase timing. Channel interviews cover component distributors and hydrogen refueling infrastructure developers, since their order books are an early read on which vehicle classes are actually converting pilots into fleet-scale orders. Sampling is weighted toward Japan, South Korea, Germany and the United States, the geographies where fuel cell vehicle programs are furthest along and where OEMs, component suppliers and fleet operators are most willing to discuss volumes and pricing on the record.

Secondary sources, this report

Desk research rests on UN GTR No. 13 type-approval filings for hydrogen fuel cell vehicles, national vehicle registration and homologation databases in Japan, South Korea, Germany and the United States, and customs classifications under HS code 8507.60 and related headings used to track fuel cell stack and hydrogen storage component trade. Refueling station counts published by the California Fuel Cell Partnership and national hydrogen strategy bodies in Germany, Japan and South Korea are used to cross-check regional deployment. Annual reports and investor filings from the named suppliers supply disclosed fuel cell and mobility segment revenue used in the top-down check.

Desk research runs across proprietary research databases including Factiva, OneSource and Hoovers alongside the public sources above. Modelling and statistical validation are run in SAS and SPSS.

Forecasting

The forecast is not a growth rate applied to a base year. It is built from the drivers that are expected to change, each one stated so a reader can disagree with it.

Forecast approach, this report

The forecast is built from fuel cell vehicle production plans already announced by OEMs, hydrogen refueling network build-out schedules published by national programs, and the pace at which total cost of ownership for fuel cell trucks and buses closes against diesel and battery-electric alternatives on long-haul and high-utilization routes. Regulatory adoption curves, particularly heavy-duty emissions rules in the European Union, California and parts of Asia, are treated as stepped: compliance deadlines pull orders forward instead of demand rising smoothly. Early-period volumes are normalized for the pandemic-era production disruption visible in the 2020-2021 historical data so recovery is not mistaken for underlying demand growth. The forecast holds only if announced refueling build-out proceeds on published schedules.

Triangulation and validation

No figure enters a report on the strength of one source. Where the two sizing routes disagree the difference is not averaged away — the assumption causing it is isolated, tested against a third independent measure, and either corrected or carried forward as a stated limitation. Historical years are back-tested against the growth actually recorded before any forecast is allowed to run forward from them.

Validation, this report

Outputs are back-tested against recorded 2020-2024 shipment and revenue growth for the same vehicle classes and geographies, checking that the model reproduces the historical trajectory before it is trusted with the forecast years. Segment-level share shifts, including the move toward higher power bands and heavier vehicle classes, are reviewed against fleet order announcements and OEM platform roadmaps, not accepted on trend alone. Sensitivities are run on hydrogen price, refueling station build-out pace and the timing of heavy-duty emissions rules, since these three assumptions move the forecast total the most. Where a sensitivity produced a materially different outcome, the underlying assumption was narrowed and the build rerun, not the headline figure adjusted directly.

Confidence and limitations

Where an estimate is firm and where it is not is stated rather than left to be inferred from the precision of the number.

Confidence framing, this report

Confidence is strongest for passenger car and transit bus volumes in Japan, South Korea, Germany and the United States, where OEM production plans and public procurement records are directly observable. It is weaker for heavy-duty trucking and off-road material handling, where fleet pilots are still small and operators disclose utilization data inconsistently. Component-level splits, particularly hydrogen storage system pricing, carry more uncertainty than vehicle-level totals because storage tank cost varies with pressure rating and vehicle packaging in ways not fully visible from public filings. A slower-than-planned refueling infrastructure build-out or a delay to announced heavy-duty emissions rules would be the two most likely causes of a downward revision.
