ITM Power
A UK maker of proton exchange membrane (PEM) electrolyzers: growing its standard products, while carrying losses and a delayed set of results

ITM Power comes up in any discussion of hydrogen because it is a UK specialist that concentrates on PEM water electrolyzers and builds the electrolysis stack itself in its own factory. In RWE's 200 MW electrolysis project at Lingen in Germany, ITM stacks are in use, and the company announced that the first hydrogen reached the customer on 4 August 2026 (the plant is ramping up toward 200 MW commercial operation). Yet revenue was only £26.0 million even in the year to April 2025, and the adjusted EBITDA loss was £33.0 million. And on 5 October 2026 the company said it would postpone its full-year results for the year to April 2026 to the second half of October, because the first-year audit by its new auditor is not finished. This profile sets out, from primary sources, what the company has put into hydrogen, what stage its projects have reached, and what still cannot be confirmed.

The one thing to grasp first

ITM Power is a company that has grown its orders by concentrating on PEM and mass-producing standard products of 2 MW, 5 MW, 20 MW and 50 MW in its own factory Sourced. Revenue rose from £5.2 million in the year to April 2023 to £26.0 million in the year to April 2025, but the business is still small, and, as the company itself puts it, the factory is not yet full enough to absorb its fixed costs, so losses continue. On the other side of the ledger, cash was about £198 million at the end of October 2025, and in April 2026 UK government-related funding (an equity investment and a grant, £86.5 million together) was added. And the latest full-year results (year to April 2026) are not out yet: the full-year figures in this article run only to April 2025 Not yet confirmed.

2. The logo and how the name is written

A note on names: the legal entity is ITM Power plc, often shortened to "ITM". The company's stack (the heart of the electrolyzer) is called TRIDENT, and its products include NEPTUNE II, NEPTUNE V, POSEIDON and ALPHA 50, all ITM brands. Its next-generation stack is called CHRONOS. The company's former 50:50 joint venture with Linde Engineering is ITM Linde Electrolysis GmbH (Dresden, Germany), a separate entity. The logo image is the white-lettered logo used in the header of the company's official website (itm-power.com); the dark blue background was added by us.

Fig. 1 The four types of hydrogen company (Electrolyzers; Fuel cells & hydrogen end-use equipment; Gases & large projects; Materials & components) and where ITM Power sits. The classification is our own, and the company names are examples from those covered in this series Our calculation. Revenue and outlook come from the company's announcements (Annual Report 2025 and the 17 February 2026 regulatory news).

4. Scale

The financial year runs from May to April (the year to April 2025 means May 2024 to April 2025). Full-year results for the year to April 2026 are not yet published; on 5 October 2026 the company announced they will come in the second half of October. The table therefore covers the years to April 2024 and April 2025, plus the first half of the year to April 2026 (May to October 2025) Sourced.

Indicator (£ million)Year to Apr 2024Year to Apr 2025First half, year to Apr 2026 (prior-year half)
Revenue16.526.018.0 (15.5)
Adjusted EBITDA-30.4-33.0-11.9 (-16.8)
Loss before taxn/an/a-14.1 (-28.8)
Loss from operations (the year to Apr 2025 includes £13.0 of exceptional items)-38.0-54.5n/a
Cash230.3207.0197.8 (31 October 2025)
Contracted order backlog79.7145.1152 (29 January 2026)

Adjusted EBITDA is a non-statutory measure the company defines. The £13.0 million exceptional item in the operating loss for the year to April 2025 is the settlement of a commercial dispute with Linde Sourced. The gross loss in the first half was £6.5 million, which the company attributes mainly to under-absorption of factory costs. Revenue had been recognized under the completed-contract method (at milestones such as delivery, testing or commissioning), which made timing lumpy. The company is now moving non-standard NEPTUNE, POSEIDON and ALPHA products to the percentage-of-completion method (revenue recognized progressively as work proceeds).

Company outlook for the year to April 2026 (updated 17 February and 9 April 2026)RangeOriginal range
Revenue£40-43 million£35-40 million
Adjusted EBITDA loss£27-29 million (unchanged)Same
Cash (year-end)£210-215 million£170-175 million
A caution

The outlook above is the company's forecast, not a result (the full-year actuals await the second half of October 2026). The raised cash outlook reflects the £40 million equity investment (a subscription for new shares) by Great British Energy in April 2026 (the company describes this as UK government backing). The 5 October 2026 notice also says the results are delayed because the first-year audit by the new auditor (BDO) is not finished. Because the audit could change the figures, treat every figure for the year to April 2026 in this article as unconfirmed.

5. Resources committed to hydrogen

ITM Power's business is concentrated on hydrogen electrolyzers, so most of its company-wide figures are effectively hydrogen figures. The table separates what could be confirmed from what could not.

Type of resourceWhat primary sources confirmStatus
People306 employees (30 April 2025; 308 a year earlier and 359 two years earlier); average 304.6. Sites: Sheffield (head office and factory) and Germany (ITM Power Germany and the Hydropulse office in Berlin). Headcount for R&D or manufacturing alone is not disclosedSourced / partly undisclosed
Money (R&D)The directors' report gives R&D-related costs of £1.7 million (£2.6 million a year earlier). Part of development spending is capitalized or booked to inventory and is treated separately from this figure. The company's R&D priorities are (1) manufacturing processes for mass production, (2) cell efficiency, (3) stack life and lower degradation, and (4) scale-upSourced
Money (capex)£6.9 million in the first half of the year to April 2026 (£4.5 million fixed assets, £2.4 million development intangibles). The full year is expected at £10-15 million (annual report outlook). The investment in the 1 GW-a-year CHRONOS line is not disclosed (public funding is in the last-but-one row)Sourced / outlook
Acquisitions, investments and joint ventures(1) ITM Linde Electrolysis GmbH (Germany; 50:50 with Linde Engineering; set up in October 2019): in the year to April 2024 it was decided to honour existing contracts but take on no new work (annual report). (2) Motive Fuels (a joint venture with Vitol) was disposed of, with a loss recorded in the year to April 2024. (3) The dispute with Linde, the largest shareholder, was settled in the year to April 2025 with a payment of £13.0 million. (4) In April 2026 Great British Energy invested £40 million (a subscription for new shares)Sourced
Universities, research institutes and public fundingA £46.5 million grant from DESNZ (the UK Department for Energy Security and Net Zero): intent to award notified on 9 April 2026, formally awarded on 9 July. It funds a 1 GW-a-year CHRONOS manufacturing line in Sheffield (catalyst-coated membrane production, electrode welding, specialist coating, stack assembly, cleanroom and more). On universities, the annual report mentions work with the University of Sheffield and the Advanced Manufacturing Research Centre on training and STEM careers (named joint R&D projects could not be confirmed). On 24 June 2026 the company signed a letter of intent (LOI) with Deutsche Bahn's DB Systemtechnik, starting with a joint FEED studySourced / partly not confirmed
Investment in start-upsNot mentioned in the materialsCould not be confirmed

In its announcement for the year to April 2025 the company also said it had been selected as supplier for an Asia-Pacific project of more than 300 MW (customer undisclosed); we could not confirm a firm contract or further details Not yet confirmed.

A materials engineer's view: what cutting iridium means

PEM water electrolysis generally uses the scarce platinum-group metal iridium as the anode catalyst Not yet confirmed (a general explanation, not a description of ITM's product specification). In its annual report ITM says it has reduced iridium loading twice, by 40% each time, while maintaining stack performance and longevity Sourced. It also says it keeps a policy for sourcing platinum group metals (PGM) and manages price and supply swings as a business risk. Because iridium output is small, it is a material that bears on how many gigawatts of electrolyzers can be built. The materials we reviewed do not, however, give the absolute amounts (for example g/kW), the test conditions or lifetime figures.

The figures above are targets or outlooks of the company or its customers, not results Not yet confirmed. The official materials also describe the following plans.

  • CHRONOS: the next-generation stack is in development and validation; the launch date could not be confirmed. The 1 GW-a-year manufacturing line is planned inside the existing Sheffield facilities (9 July 2026)
  • MorGen West Wales (20 MW): commissioning targeted for 2028 (the customer's target)

  • Hydropulse: several projects under discussion; a specific operating project could not be confirmed
  • Rheinmetall (Giga PtX): support for a concept of several hundred decentralized synthetic-fuel plants of up to 50 MW each across Europe. An early-stage collaboration; no contract or volumes could be confirmed
  • DB Systemtechnik: a joint FEED study on hydrogen for rail (letter-of-intent stage)
What could not be confirmed

Audited actuals for the year to April 2026; CHRONOS launch timing and published performance figures; any orders for ALPHA 50; the FID of Uniper's Humber H2ub; details of the Asia-Pacific project above 300 MW; any operating Hydropulse project and how it is financed; named joint research with universities; and a company-wide manufacturing capacity in GW a year (the only figure is a stack-assembly line capability described as "over 2 GW"). None of these appears in the materials we reviewed.

8. What the company is aiming for in hydrogen

This section separates what the company says directly from what we read into it. Inference marks our own interpretation of primary information.

What we read from itPrimary information behind itStatus
It concentrates on PEM and sells combinations of standard productsFour standard products: 2 MW (NEPTUNE II), 5 MW (NEPTUNE V), 20 MW (POSEIDON) and 50 MW (ALPHA 50). The 2023 results say the product portfolio was significantly simplifiedSourced
For large projects it sells a complete plant at a stated price, not just equipmentALPHA 50 is a complete plant that needs only water and electricity and delivers hydrogen at 30 bar, with a price of EUR 50 million stated. The company claims it is more competitive than comparable offers (we make no judgment of ranking)Sourced (company claim) / Inference (direction)
It keeps its stack design and manufacturing in-house and moves to volume with the next generationThe company says it fully owns its core science and manufacturing processes. The CHRONOS 1 GW-a-year line (catalyst-coated membranes, electrode welding, stack assembly) is funded by government moneySourced
Beyond selling equipment, it is stepping into supplying hydrogen (owning and operating)Hydropulse (BOO) has begun. The CEO describes the Protium partnership as a framework ranging from equipment supply to investmentSourced / Inference (how much it will own)
The UK and Germany are its main fields, with newer uses such as defence and rail being triedMost projects sit in the UK (HAR) and Germany. Collaborations with Rheinmetall and DB SystemtechnikSourced / Inference (positioning)
The basis for one inference, in more detail

We read "stepping into supplying hydrogen" mainly from how the company describes the purpose of Hydropulse. The company presents Hydropulse as a way to lower the bankability hurdle of green hydrogen projects by taking on capital expenditure, operating and technology risk Sourced. In other words, ITM itself would take on the risk that stops customers reaching a final investment decision (FID). At the same time, ITM has about £200 million in cash and continuing operating losses, so the scale of assets it can hold itself must be limited. We therefore read the likely shape as "not full self-ownership, but project-by-project arrangements with outside investors such as Protium" Not yet confirmed. This is our interpretation, not a policy the company has stated.

9. Map of partnerships in hydrogen

Hydrogen partnerships centered on ITM Power Only relationships stated in the annual report and regulatory news; no press-report-based ties ITM PEM electrolysis Linde 16.2% holder, JV, co-supplier Great British Energy £40m equity investment DESNZ (UK government) £46.5m grant Protium Partnership, Cromarty 15 MW Rheinmetall Collaboration, e-fuel concept DB Systemtechnik Letter of intent, joint FEED RWE Lingen 200 MW, 150 MW reserved Shell REFHYNE II, 100 MW Yara 24 MW, inaugurated MorGen Energy 20 MW, FID reached Uniper 120 MW, FEED Stablegrid 710 MW, selected as supplier Equity, JV, grant Partnership Supply / orders (customers)
Fig. 2 ITM Power's hydrogen partnerships. Sources: Annual Report 2025 and regulatory news announcements. Only relationships described in official materials are shown, and project stages differ (Uniper and Stablegrid are at the "selected" stage; Protium, Rheinmetall and DB Systemtechnik are at the partnership or letter-of-intent stage). Linde appears in several roles: the ITM Linde Electrolysis joint venture (no new orders), joint delivery at Lingen, and the largest shareholder.

What stands out at ITM Power is that its largest shareholder, Linde, is at once a joint supplier and a party that received a settlement payment after a past dispute Sourced. One non-executive director on the board was nominated by Linde (annual report), and the Chair since January 2026, Jürgen Nowicki, is a former CEO of Linde Engineering. The annual report says directors recognize their duty to act in the interests of the company as a whole rather than of any one shareholder. How the relationship with Linde will affect future projects cannot be confirmed from the company's materials Inference.

10. Technologies, products and services

Product specifications below come only from the company's official data sheets and announcements. The figures are manufacturer's stated values; values measured under different conditions and scales are not set side by side to rank products (the power consumption in the table is for the whole system at beginning of life).

AreaWhat official materials list (manufacturer's stated values)Note
TRIDENT (2 MW skid)PEM. 3 stacks, 36 kg/h of hydrogen, output pressure 31 bar(g), operating range 25-100%, ambient temperature -20 to +40 °C, ramp of 10% per second up and 50% per second down, CE and ASME complianceThe basic stack unit. ITM describes it as a 30 bar-class stack
NEPTUNE II / VNEPTUNE II is an autonomous 2 MW plug-and-play plant. NEPTUNE V is a 5 MW containerized complete plant, including balance of plant. Several units can be linked into larger plantsNEPTUNE V is a mid-size product that the company says has drawn strong demand since launch
POSEIDON (20 MW module)PEM. 30 stacks, 360 kg/h of hydrogen, output pressure 31 bar(g), operating range 20-100%, whole-system AC power consumption of 55.9 kWh/kg (at beginning of life, including water purification, stacks and balance of plant), footprint 35 x 15 x 7.5 m, indoor or outdoor installation, CE and PED complianceThe unit used in the 20 MW projects at Lingen, for Uniper and for MorGen
ALPHA 50 (50 MW complete plant)PEM. 80 stacks, 900 kg/h of hydrogen, output pressure 30 bar(g), operating range 12.5-100%, AC power consumption 55.9 kWh/kg (same basis), hydrogen purity of under 5 ppm water and under 5 ppm oxygen (referring to EN 17124 and ISO 14687), footprint 74 x 35 m, outdoor installation, price EUR 50 million on standard termsLaunched in October 2025; orders could not be confirmed
Next-generation stack CHRONOSIn development and validation. The company aims for higher efficiency and lower cost. A 1 GW-a-year manufacturing line is plannedPublished performance figures could not be confirmed
Services and hydrogen supplyLong-term service agreements (ten years for MorGen). Hydropulse (build, own, operate). Decentralized hydrogen plants built from containerized NEPTUNE unitsThe core revenue is still equipment sales
A materials engineer's view: the materials in a PEM stack, and how to read the data sheet

A PEM electrolysis stack generally consists of an electrolyte membrane, catalyst layers (iridium on the anode, platinum on the cathode, for example), porous transport layers, bipolar plates and seals Not yet confirmed (a general explanation, not a description of ITM's design). The clues in ITM's official materials are three: (1) the investment scope of the CHRONOS line, which lists catalyst-coated membrane production, electrode welding, specialist coating, stack assembly and a cleanroom; (2) the continuing work to reduce iridium loading; and (3) a stack output pressure of 31 bar(g) Sourced. A thinner membrane lowers electrical resistance, but under pressurized operation there is a trade-off with hydrogen permeation and mechanical strength Not yet confirmed (a general explanation).

Note that the data-sheet power consumption (55.9 kWh/kg) is a beginning-of-life value and rises as the stack degrades with operating time. We could not find published degradation rates or lifetime figures in ITM's materials. See also our explainers on PEM water electrolysis and on platinum group metals and catalysts.

11. The risks this company carries

RiskDetailStatus
Losses and fixed-cost absorptionAdjusted EBITDA was -£33.0 million in the year to April 2025 and -£11.9 million in the first half of the year to April 2026. The company says the factory is not yet full enough to absorb fixed costs (first-half gross loss of £6.5 million)Sourced
Loss-making legacy contracts71% of the order backlog is profitable contracts (January 2026). The remaining legacy contracts add no margin but are fully provided for, and are expected to be recognized over about the next 18 monthsSourced
Delayed results and change of auditorFull-year results for the year to April 2026 are postponed to the second half of October. The new auditor's (BDO) first-year audit is not finished. The annual report will not be ready for the shareholders' meeting on 30 October 2026Sourced
Customers' FIDs slippingThe company itself says market-wide FIDs have run later than first projected. Many projects depend on support schemes such as those in the UK and GermanySourced / Inference (degree of dependence on support schemes)
Orders that are not firmRWE's 150 MW is a capacity reservation, Stablegrid's 680 MW is at pre-FEED, and the Asia-Pacific project above 300 MW is undisclosed. FIDs depend on customersSourced
Relationship with the largest shareholder, LindeLinde holds 16.2% and nominated one director. A past commercial dispute was settled with a £13.0 million payment. Linde is also a joint supplierSourced
Track record of new productsCHRONOS has not been launched; ALPHA 50 was launched recently and no order could be confirmed. Data-sheet values are manufacturer's stated values and independent verification could not be confirmed from the materialsSourced / Not yet confirmed
Precious-metal price and supplyThe company keeps a platinum group metal sourcing policy and manages price and supply swings as a risk. It continues to work on using less iridiumSourced
Policy changesIn the U.S. the company says a broader rollback of clean-energy incentives is likely to pose challenges, and it keeps an asset-light approach there (annual report)Sourced
Capital burden of owning and operating (Hydropulse)Owning and operating hydrogen supply needs capital. Terms with outside investors could not be confirmedInference
