Bosch’s PEM Electrolysis Strategy in 2025: Dominating the Green Hydrogen Component Market

From Development to Dominance: Bosch’s Commercial Scale-Up of PEM Electrolyzer Stacks

Bosch executed a definitive shift from development to commercial deployment in its hydrogen business during 2025, validating its strategy to supply core components for green hydrogen production. The company moved beyond its 2021-2024 focus on research and prototyping to secure substantial commercial traction and begin serial production. This pivot allows Bosch to capitalize on the universal demand for electrolysis technology while mitigating the high capital risks associated with direct project development.

• Between 2021 and 2024, Bosch’s efforts were concentrated on technology development, culminating in the delivery of its first 1.25 MW PEM electrolyzer prototypes to pilot customers in April 2024. This period established the technical foundation for its hydrogen ambitions.
• The year 2025 marked the commercial inflection point, beginning with the strategic decision in February 2025 to discontinue its solid-oxide fuel cell (SOFC) operations and focus entirely on PEM electrolysis stacks. This was immediately followed by securing 100 MW in pre-orders before the official product launch.
• Commercial validation arrived with the delivery of a 1.25 MW Hybrion stack to Kyros Hydrogen in Canada for a waste management project in September 2025 and the delivery of a 2.5 MW containerized system with integrator FEST GmbH in July 2025.
• To showcase its own technology, Bosch commissioned a 2.5 MW in-house electrolyzer at its Bamberg, Germany site in November 2025, demonstrating a production capacity of over 1 metric ton of green hydrogen daily.

Investment Analysis: Bosch’s €2.5 Billion Capital Injection into the Hydrogen Economy

Bosch has committed significant capital to establish a leadership position in hydrogen component manufacturing, with investments allocated for scaling production, expanding infrastructure, and achieving its long-term revenue goals. The funding strategy supports both its near-term production targets and its 2030 vision for the hydrogen business.

Partnership Strategy: Building a Global Ecosystem for PEM Electrolyzer Stack Integration

Bosch has rapidly built a global network of strategic partnerships to accelerate market penetration for its Hybrion PEM electrolysis stacks. Instead of developing end-to-end solutions alone, the company is enabling system integrators, technology developers, and research institutions to build upon its core component technology. This collaborative model is essential for scaling deployment and embedding its technology across different applications and geographies.

Geographic Analysis: Bosch’s Expansion from European R&D Hubs to Global Commercial Markets

Bosch has expanded its operational footprint from a Europe-centric development base to a global commercial theater in 2025, with strategic entries into North America and Asia. While its core R&D and initial manufacturing remain anchored in Germany, its commercial and partnership activities now reflect a global market-facing strategy.

• Between 2021 and 2024, Bosch’s activities were heavily concentrated in Europe, with major investments in its German plants at Stuttgart, Bamberg, and Homburg, alongside the development of a 1 MW SOEC pilot with Ceres in Stuttgart.
• The year 2025 marks a distinct geographic expansion, starting with the multi-year supply agreement signed with Beijing-based Hygreen Energy in July 2025. This provides Bosch with a significant channel to the large-scale industrial hydrogen market in China and other global projects pursued by Hygreen.
• North America became a key focus with the announcement in September 2025 that its Hybrion PEM stacks received ASME and CSA/ANSI certifications, officially opening the U.S. and Canadian markets for commercial sales.
• This market access was immediately followed by the shipment of a 1.25 MW stack to Kyros Hydrogen Solutions in Canada, marking Bosch’s first announced commercial deployment in a North American industrial project.

Technology Maturity: Bosch’s PEM Electrolysis Reaches Commercial Readiness in 2025

Bosch’s PEM electrolysis technology successfully transitioned from the prototype and pilot phase to initial commercial production and deployment in 2025. This was validated by third-party commercial agreements, regulatory certifications, and the launch of in-house production facilities operating at the megawatt scale.

• The 2021-2024 period was defined by technology maturation, where Bosch leveraged its automotive manufacturing expertise to design the Hybrion stack for mass production. This phase culminated in the April 2024 delivery of 1.25 MW prototypes to pilot customers, establishing a baseline performance of 23 kg/hr of hydrogen production.
• In March 2025, the technology achieved commercial launch status with the official unveiling of the Hybrion PEM electrolysis stack at Hannover Messe, supported by the announcement of 100 MW in pre-orders, which confirmed market appetite.
• The technology’s readiness for global markets was confirmed in September 2025 upon receiving critical ASME and CSA/ANSI certifications for North America, moving it beyond a Europe-only solution.
• The commissioning of the 2.5 MW electrolyzer at Bosch’s Bamberg site in November 2025 serves as the final proof point, demonstrating the technology’s reliability and performance in an operational, industrial setting.

Forward-Looking Insights: From Orders to Execution for Bosch in 2026

The critical action for Bosch in the year ahead is the successful execution of its order book and the tangible scaling of its automated production lines. Having proven market demand and technological readiness in 2025, the focus now shifts to industrial-scale manufacturing to meet commitments and drive down costs. The company’s ability to transition from initial deliveries to high-volume output will determine its market leadership.

• Watch for announcements detailing the fulfillment of the 100 MW in pre-orders secured in March 2025. Identifying the customers and project timelines will be a key indicator of Bosch’s ability to execute on its backlog and solidify its market position.
• Following the North American certifications obtained in September 2025, expect a series of new partnership and supply agreements in the U.S. and Canadian markets. The delivery to Kyros Hydrogen is likely the first of many such deals.
• Monitor for updates from Bosch’s manufacturing plants, particularly in Bamberg and Stuttgart, regarding the ramp-up of automated, high-volume production. Achieving cost efficiencies through industrialization is the core tenet of its strategy.
• Look for results from research collaborations like the SuperCell project. Any announcements of next-generation cell technology that lowers the energy consumption below the current ~50 kWh/kg or reduces reliance on precious metals would signal a significant competitive advantage.

Frequently Asked Questions

What is Bosch’s primary product in the green hydrogen market?
Bosch’s primary product is the core component for green hydrogen production: the PEM (Proton Exchange Membrane) electrolysis stack, which it markets under the name “Hybrion.” The company focuses on supplying these stacks to system integrators rather than selling complete, end-to-end electrolysis systems.

Why was 2025 such a pivotal year for Bosch’s hydrogen business?
The year 2025 marked Bosch’s definitive shift from a development phase to commercial deployment. Key events included discontinuing its solid-oxide fuel cell (SOFC) operations to focus entirely on PEM electrolysis, securing 100 MW in pre-orders, and making its first commercial deliveries to partners like Kyros Hydrogen and FEST GmbH.

How much capital has Bosch invested in its hydrogen strategy?
Between 2021 and 2026, Bosch allocated a total of nearly €2.5 billion for the development and manufacturing of hydrogen technologies. A significant portion of this, up to €500 million, is specifically dedicated to establishing high-volume, automated production of its PEM electrolysis stacks by 2030.

Is Bosch selling its electrolyzer technology in North America?
Yes. In September 2025, Bosch officially entered the U.S. and Canadian markets after its Hybrion PEM stacks received critical ASME and CSA/ANSI certifications. The company immediately followed this by delivering its first commercial stack in the region to Kyros Hydrogen in Canada.

What is Bosch’s go-to-market strategy for its electrolyzer stacks?
Bosch’s strategy is to act as a core component supplier. It partners with system integrators, such as FEST GmbH in Europe and Hygreen Energy in Asia, who build and deliver complete electrolysis systems using Bosch’s Hybrion stacks. This collaborative model allows Bosch to accelerate market penetration globally.
