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.
The size is built upward from installed and commissioned electrolyzer capacity by technology and region, multiplied by utilisation hours to give annual green hydrogen output, then by the realised delivered price per kilogram for captive and merchant supply. Capacity comes from project registers and company order books; prices come from tender results, offtake announcements and levelised cost inputs for renewable power and electrolyzer capital cost. The build is then checked against disclosed revenue from electrolyzer makers, industrial gas suppliers and project developers, adjusted for the share attributable to green hydrogen. Where the check and the build diverge, the utilisation or price assumption in the build is corrected; the disclosed figures are not averaged in.
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.
- 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
- 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.
- 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
- 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
Interviews target the roles that decide purchases and project approvals: heads of hydrogen and new energy at industrial gas suppliers, project development and procurement leads at refiners, ammonia and steel producers, technology and sales directors at electrolyzer manufacturers, and regulatory and permitting specialists at utilities and public agencies. Channel views come from EPC contractors and balance-of-plant suppliers who see real installed cost. Sampling emphasises Europe, where subsidy auctions are most advanced; Asia Pacific, where China and India carry most manufacturing and announced capacity; North America under tax-credit rules; and the Middle East, where export-oriented projects are concentrated.
Desk research rests on the IEA Hydrogen Production and Infrastructure Projects Database, IRENA renewable power cost statistics, the US Department of Energy Hydrogen Program records and Section 45V guidance, European Hydrogen Bank auction results, and the delegated acts under the EU Renewable Energy Directive that define renewable fuels of non-biological origin. Trade flows are read from customs data under HS code 2804.10. Company annual reports, 10-K and 20-F filings and capital markets presentations supply electrolyzer order books, backlog and segment revenue, and capacity statements from Hydrogen Europe and the Hydrogen Council cover announced projects.
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.
The forecast is built from the project pipeline converted to commissioned capacity with a delay and attrition haircut by region, electrolyzer capital cost declines by technology, and renewable power prices by location. Demand is modelled application by application, starting with ammonia and refining where hydrogen is already used, then steel reduction, e-fuels and mobility as offtake contracts reach final investment decisions. Drivers are modelled explicitly and netted against the restraints. For the forecast to hold, subsidy schemes must stay in force through the late 2020s, grid and permitting queues must clear, and delivered green hydrogen must move toward the cost of grey hydrogen under carbon pricing.
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.
Outputs were back-tested against recorded capacity additions and reported electrolyzer shipments for 2020 to 2025, and the implied historical growth was compared with the growth in company order intake. Segment shifts, including the move from alkaline toward PEM and solid oxide systems and the rise of giga-scale plants, were reviewed with technology and project specialists. Sensitivities were run on utilisation hours, delivered price per kilogram, project cancellation rate and subsidy continuity, and the sum of driver contributions less restraint reductions was reconciled to the change in market value between 2025 and 2034.
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 is medium. The estimate is firmest for alkaline and PEM electrolysis, ammonia and refining applications, and Europe and China, where capacity and order books are reported. It is thinner for solid oxide and anion exchange systems, for storage and distribution forms, and for the Middle East and Latin America, where projects are announced earlier than they are built. A band of 1.8 to 3.4 Billion surrounds the 2025 base. Delayed final investment decisions, changes to subsidy rules and slower cost declines are the main risks that would force a downward revision of the 2034 value.
