COMPANY PROFILE / HYDROGEN ENERGY

thyssenkrupp nucera
A dedicated electrolysis specialist taking technology proven in chlor-alkali into gigawatt-scale alkaline water electrolysis

thyssenkrupp nucera comes up in any discussion of hydrogen because it is one of the few suppliers that delivers large alkaline water electrolysis (AWE) plants by lining up standardized 20 MW modules. In its September 2026 investor presentation the company puts the hydrogen projects it is executing at about 3.5 GW in total (Sweden, Saudi Arabia, the Netherlands, Spain and others). Yet its quarterly statement of August 2026 shows an EBIT (operating result) loss of €107 million in the hydrogen segment for the first nine months, and the company has dropped its plan to build its own mass-production capacity for high-temperature solid oxide electrolysis cells (SOEC). This profile sets out, from primary sources, what the company is putting into hydrogen, what stage each project has reached, and what supports its earnings.

The one thing to grasp first

thyssenkrupp nucera is both a "hydrogen company" and a "chlor-alkali electrolysis company". In the company's materials, sales are split into two segments, Green Hydrogen (gH2) and Chlor-Alkali (CA); in FY2024/25 hydrogen made up 54% of sales. In the first nine months of FY2025/26, however, hydrogen sales were €80 million against €273 million for chlor-alkali, which therefore accounted for about 77% Our calculation. Large hydrogen projects are booked as sales in line with project progress, so sales swing sharply from year to year as projects (NEOM and others) pass the point where most of their revenue has already been recognized Sourced. And the cell design behind the hydrogen segment's electrolyzers rests on technology that has long been used in chlor-alkali electrolysis (the company counts chlor-alkali electrolysis orders from 1977 to 2025, more than 600 projects).

2. The logo and how the name is written

A note on names: the legal entity is thyssenkrupp nucera AG & Co. KGaA, a partnership limited by shares whose general partner is thyssenkrupp nucera Management AG. The company writes both "thyssenkrupp" and "nucera" in lower case. It is a separately listed company from its parent thyssenkrupp AG (50.2% stake), and, according to the company's materials, also from thyssenkrupp Uhde and from Industrie De Nora (an Italian electrochemistry company and the second-largest shareholder). The logo image (white on a purple ground) was taken from the logo embedded in the company's official website (thyssenkrupp-nucera.com).

The classification is our own, and the company names are examples from those covered in this series Our calculation. The sales shares are our calculation from the company's FY2024/25 announcement (17 December 2025) and its quarterly statement of 12 August 2026.

4. Scale

The financial year runs from October to September (FY2025/26 ended on 30 September 2026; the annual report is scheduled for 16 December 2026) Sourced. Full-year results for FY2025/26 are not out yet, so the table below sets the full years to FY2024/25 beside the nine-month figures for FY2025/26.

Employees1,076 (1,092 at 30 September 2025)30 June 2026

The company explains that in FY2024/25 hydrogen sales were driven largely by the Stegra project in Sweden, while NEOM contributed less because it was already far advanced Sourced. In FY2025/26 hydrogen sales fell sharply as sales recognition on existing large projects such as NEOM had already progressed, and as higher costs on new-build projects arose in the second quarter. The company's documents give the chlor-alkali segment's FY2024/25 sales as both €386 million and €387 million (probably a rounding difference Inference).

A caution

Hydrogen-segment sales rise and fall project by project. For FY2025/26 the company attributes the decline mainly to sales that were already largely recognized on large existing projects such as NEOM, and to extra costs on new-build projects. New orders (hydrogen order intake of €184 million in the first nine months of FY2025/26 against €23 million a year earlier, mainly the Moeve project) were expected, in the FY2024/25 announcement, to lift sales only in later years Sourced. A single year or quarter does not show whether the hydrogen business is doing well or badly.

5. Resources committed to hydrogen

Most figures specific to hydrogen are not disclosed. The table separates what could be confirmed from what could not.

Type of resourceWhat primary sources confirmStatus
PeopleThe group has 1,076 employees (30 June 2026) at 10 locations worldwide (company materials): Dortmund (HQ), Arnstadt (linked to SOEC; the August announcement said its future use is under review), Tokyo, Okayama, Milan, Houston, Riyadh, Mumbai, Shanghai and Perth. Hydrogen-only headcount is not disclosedSourced / partly undisclosed
Money (R&D)R&D expense was €38 million in FY2024/25 (€36 million a year earlier) and €29 million in the first nine months of FY2025/26 (€24 million a year earlier, +19%). Company materials say development focused mainly on AWE and SOEC technology (partly capitalized). R&D spending for hydrogen alone is not disclosedSourced / partly undisclosed
Money (capex)In the nine-month cash flow statement for FY2025/26, capital expenditure on property, plant and equipment was €11 million and on intangible assets €11 million. The company describes an asset-light business model. Plant investment specific to hydrogen is not disclosedSourced / partly undisclosed
Acquisitions, investments and joint ventures(1) Key technology assets of Green Hydrogen Systems (Denmark): agreement announced on 20 June 2025, covering intellectual property and a full-size test facility in Skive, Denmark (price undisclosed). (2) Cooperation on cell design with Industrie De Nora, the second-largest shareholder (25.9%); in the company's chlor-alkali cell materials, De Nora supplies the electrode coatings and half-shells. (3) In August 2026 the company decided not to build its own SOEC mass-production capacity, with a one-off hit of about €30 million to EBIT, mainly from impairment of the pilot plant and capitalized development costsSourced
Universities, research institutes and public fundingUnder H2Giga (the German Federal Ministry of Education and Research's hydrogen flagship project), the "INSTALL AWE" project to industrialize AWE production receives about €8.5 million in subsidies (the company writes "almost 8.5 million euros"). Carbon2Chem (BMBF-supported) hosts a 2 MW AWE plant in Duisburg. On SOEC the company has a strategic R&D partnership with Germany's Fraunhofer IKTS and a license to its SOEC stack technology (how this is treated after the August 2026 decision could not be confirmed)Sourced
Investment in start-upsNot mentioned in the materialsCould not be confirmed

Next, the main projects. Stages are given in the wording of the company's own materials. Customers' financing and start-up dates must be checked in each customer's own disclosures; we have not done so here.

The company also shows its wider pipeline. It is actively pursuing 35 projects totalling about 14 GW (expected contract value about €7 billion), with paid engineering contracts for about 1.9 GW under way, and expects its next project award during calendar 2026 (as of August 2026) Not yet confirmed.

A materials engineer's view: what a replaceable single cell implies

According to the company, a 20 MW AWE module holds about 300 cells split across four racks (74 cells per rack) Sourced. Each cell can be removed and replaced individually, and the design is described as allowing cells to be refurbished and reused rather than scrapped. From a materials standpoint this reads as a design premise that the cell is where the diaphragm, electrodes and seals are most likely to degrade Inference. If a faulty part can be swapped cell by cell, the whole stack need not be discarded and spares inventory shrinks. The materials we reviewed give no figures, however, for actual lifetime, degradation rate or replacement frequency.

  • Products: pressurized electrolyzers (up to 35 bar), a 120 MW plug-and-play electrolysis system and a 360-degree lifecycle service portfolio. The company's priorities for 2026 are standardization, modularization and scale, cost discipline, and financial stability
  • SOEC: no own mass production, but how the Arnstadt site and existing expertise will be used is still being reviewed (as of August 2026)
What could not be confirmed

Hydrogen-only headcount, R&D spending and plant investment; published figures for AWE specific energy consumption (kWh per kg of H₂) or degradation rate; start-up dates for NEOM and Stegra (these need the customers' own disclosures); timing and volumes of localization with BHEL; whether the company invests in start-ups; and what will become of the SOEC assets at Arnstadt. None of these appears in the company materials we reviewed.

8. What the company is aiming for in hydrogen

This section separates what the company says it is aiming for from what we read into its materials. Inference marks our own interpretation of primary information.

What we read from itPrimary information behind itStatus
In hydrogen, it is narrowing to "standardize AWE and build it in volume"The 20 MW standard module, a cell supply chain of 1 GW per year, and the August 2026 statement that it will focus on chlor-alkali, industrial-scale AWE and high-pressure water electrolysis after dropping SOEC mass productionSourced
It is moving toward selling the plant and its operation, not just the electrolyzerIntegrated systems including balance of plant (BoP), a 120 MW plug-and-play system, and 360-degree services. The company estimates more than €2 billion in service sales potential over 25 years from the roughly 3.5 GW under execution (assuming long-term service agreements)Sourced (company description) / Inference (direction)
It is extending products toward higher pressure and less compressionAcquisition of Green Hydrogen Systems assets (up to 35 bar); the company says additional compression is in many cases unnecessarySourced
It is making India its next anchor marketCooperation with GIZ (February 2026), the 260 MW FEED for Juno Joule, the BHEL collaboration, and statements by the head of its Indian subsidiarySourced / Inference (positioning)
It absorbs hydrogen losses with chlor-alkali profits and cash on handChlor-Alkali EBIT stays positive, net financial assets are €627 million, and the company says it is protecting financial flexibilitySourced / Inference
The basis for one inference, in more detail

We read "narrowing its hydrogen route" mainly from two August 2026 announcements made together. The company explained that investing in independent SOEC mass-production capacity is not economically attractive, citing the delayed ramp-up of the hydrogen market and continuing uncertainty over project developers' investment conditions. The same document stresses a deliberately selective approach to projects and cost discipline Sourced. Over the same period, however, it won the Moeve (300 MW) order and signed a collaboration in India. So our reading is "win projects, but do not spend capital on new technology where demand is uncertain" Not yet confirmed. This is our interpretation, not a policy the company has stated.

9. Map of partnerships in hydrogen

Hydrogen partnerships centered on thyssenkrupp nucera Only relationships stated in company materials and press releases; no press-report-based ties nucera Electrolyzers thyssenkrupp AG Parent, 50.2% stake Industrie De Nora 25.9% holder, cell design Public Investment Fund Saudi Arabia, 6.0% holder Green Hydrogen Systems Pressurized tech acquired Stegra (Sweden) 740 MW, modules installed NEOM (Saudi Arabia) 2.2 GW, in progress Shell (Netherlands) 200 MW, commissioning 2026 Moeve (Spain) 300 MW, EPF contract Mar 2026 BHEL (India) Local manufacturing, bids Fraunhofer IKTS SOEC R&D partner, license Co-development Supply / orders Equity, shareholder, asset purchase
Fig. 2 Hydrogen partnerships centered on thyssenkrupp nucera. Sources: General Investor Presentation (September 2026), press releases and official technology pages. Only relationships described in the company's materials are shown. How the Fraunhofer IKTS SOEC partnership is treated after the August 2026 decision to stop SOEC mass production could not be confirmed. Juno Joule (India, 260 MW, FEED only) is left out because its project stage differs from the others.

Of the partners named in the company's materials, the one cooperating substantively on design and manufacturing is De Nora. The chlor-alkali cell materials spell out the split of work: cell design, electrode coatings and half-shell manufacturing Sourced. For scaling up hydrogen cell production, the description of H2Giga likewise calls the relationship with joint-venture partner De Nora central to ramping up series production. The cell supply chain may therefore depend heavily on De Nora, which is also a shareholder, but the materials do not let us gauge how heavily Inference.

10. Technologies, products and services

Product specifications below come only from the company's official pages and investor presentation. Electrolysis efficiency and lifetime figures cannot be compared unless temperature, pressure, current density, operating time and scale are matched, so we do not use them to compare against other companies.

AreaWhat official materials listNote
Alkaline water electrolysis (AWE): scalumA standard 20 MW unit (about 300 cells per unit). Each cell can be removed individually. Plants can be scaled up to gigawatt size. Designed for dynamic operation that follows variable renewable power. The company states that TÜV Rheinland certified the foundational design against the requirements of Chapter 4 of ISO 22734:2019ISO 22734 is the international standard for water electrolysis hydrogen generators. The certificate covers the "foundational design" and does not guarantee the performance of any delivered plant
Pressurized AWETechnology acquired from Green Hydrogen Systems. Operates at up to 35 bar; the company says additional compression becomes unnecessary for some uses. The investor presentation refers to the product name "scalum vana"We could not confirm commercial delivery of this product
Plug-and-play systemA new offer of a 120 MW electrolysis system supplied as a complete plant (announced May 2026)No orders confirmed
Balance-of-plant (BoP) integrationTransformers and rectifiers, KOH purification, conditioning and storage, cooling water systems, piping, and hydrogen compression and purification, designed together with the electrolyzerThe company says hydrogen cost is set by the whole system, not by the electrolyzer alone
Services and digitalA 360-degree lifecycle service portfolio (spare parts, maintenance, remote load balancing, predictive maintenance), digital twins, "nucera evaluator" and "nucera load balancer"The company estimates more than €2 billion in hydrogen service sales potential over 25 years (assuming long-term service agreements)
Chlor-alkali electrolysis (CA)BM (bipolar membrane), BiTAC, NaCl-ODC and hydrochloric acid electrolysis (HCl-ODC). More than 600 projects, 240,000 cell elements and over 10 GW of installed capacity (electrolyzer capacity equivalent). The latest BM generation needs under 1,960 kWh per tonne of NaOH at 6 kA/m² (manufacturer's stated value; this is electricity per tonne of caustic soda, not per unit of hydrogen)In chlor-alkali, hydrogen is a by-product. The company estimates its market share at about 50% (company estimate)
Demonstration plantCarbon2Chem pilot, Duisburg: 2 MW, up to 440 Nm³/h of hydrogen, purity above 99.95% (dry basis). The company estimates about 1,500 tonnes produced since April 2018Demonstration-scale (2 MW) values, not values for a large commercial plant
A materials engineer's view: where materials matter in an alkaline electrolysis cell

The company's investor presentation groups the key points of its AWE cell design into electrical, hydraulic and mechanical design Sourced.

(1) Zero-gap structure: an expanded-metal current distributor and a woven-mesh cathode press against the whole face of the separator. An elastic element provides the contact pressure, and this compression is described as independent of the sealing force. The company says this extends separator life and improves performance. (2) Uniform current: continuous laser welding evens out the current distribution and reduces ohmic loss. (3) Sealing: strong flange and bolt forces compress the gaskets, aiming for a cell that stays leak-tight throughout its service life. On materials selection, the company lists corrosion-resistant materials, current distribution and electrical contacts, gas and liquid flow design, and sealing among its own contributions, and the electrode catalytic coatings and the manufacture of the half-shells among De Nora's (from the chlor-alkali cell materials).

In general, alkaline electrolysis uses a concentrated alkaline solution such as potassium hydroxide, so metals, resins and gaskets in contact with the electrolyte must resist corrosion Not yet confirmed (this paragraph is a general explanation, not a statement from company materials). The materials we reviewed do not give the specific separator and seal materials, the electrode catalyst types, or degradation rates. See also our explainers on alkaline water electrolysis and on electrolyzer stacks and materials.

11. The risks this company carries

RiskDetailStatus
Losses in the hydrogen segmentHydrogen EBIT was -€107 million in the first nine months of FY2025/26. The full-year outlook for the hydrogen segment is -€155 million to -€135 millionSourced
Lumpy sales from projectsSales are booked as projects progress and fall quickly once large projects pass their peak. Hydrogen sales go from €459 million in FY2024/25 to an outlook of €100-130 million for FY2025/26Sourced (the outlook is Not yet confirmed)
Cost of project executionIn the second quarter of FY2025/26, higher costs on new-build projects and the termination of a 20 MW pilot-plant contract in the U.S. weighed on sales and EBIT (tens of millions of euros in total; the original wording is mid-double-digit million euros). The company says it brought forward improvements based on experience so far, ahead of commissioningSourced
Market ramp-up and policy environmentThe company itself cites the delayed ramp-up of the hydrogen market and uncertainty over project developers' investment conditions as reasons for dropping SOEC mass production. Whether projects reach a final investment decision (FID) depends on customers and policySourced
Losses from technology choicesAbout €30 million in one-off losses, including impairment of the SOEC pilot plant and development costsSourced
Dependence on customers' financing and start-upThe hydrogen backlog is €325 million. Converting it to sales depends on how customers' construction and financing proceed (we have not checked each customer's position)Inference
Reliance on chlor-alkali for earningsThe group's profit is supported by the chlor-alkali segment. The company says demand tracks GDP, so the segment is exposed to the chemical industry cycleSourced / Inference (exposure to the cycle)
Dependence on shareholders and supply chainthyssenkrupp AG (50.2%) and De Nora (25.9%) are shareholders, and De Nora cooperates on cell design, coatings and manufacturing. How heavy the dependence is could not be confirmedInference
Difficulty of outside verificationHydrogen-only headcount, R&D spending and plant investment, and AWE specific energy consumption and degradation rates, are absent from published materials, so efficiency and technical standing are hard to verify from outsideNot yet confirmed

This article summarizes a company and is not advice on handling or operating hydrogen. The handling of hydrogen, potassium hydroxide and similar substances is governed by national laws, standards and operators' own safety rules.
