Bosch believes that a climate-neutral world is only achievable with hydrogen. The company has committed itself to building a robust hydrogen economy and is actively contributing to every stage of the hydrogen value chain. Bosch is not only focused on the use of hydrogen but is also developing technologies for its production, storage, and infrastructure. This comprehensive engagement is designed to open new business opportunities while driving the global energy transition.
Bosch brings to the hydrogen economy its long-standing expertise in automotive systems. The company’s two core strengths — industrial excellence and systems know-how — give it a competitive edge. Industrial excellence allows Bosch to scale up new developments into mass production efficiently, while its deep systems know-how enables the integration of complex electronics and sensor technologies across various components
Hydrogen mobility: a vital complement to electromobility
Bosch recognises hydrogen mobility as a critical supplement to battery-electric transportation, especially in the commercial vehicle sector. While batteries are well-suited to lighter vehicles and short trips, long-haul transport and heavy-duty applications demand additional solutions. Here, a combination of battery systems, fuel cells, and hydrogen combustion engines is essential.
Volume production of Bosch’s fuel-cell stack began at the end of 2022, with fuel-cell power module production starting in Stuttgart-Feuerbach in mid-2023. Bosch offers full systems or individual components like the stack, electric air compressor, hydrogen metering valve, and storage parts depending on customer needs.
To support the growing market, Bosch formed a joint venture in 2021 with Ǫingling Motors, establishing a dedicated engineering and production facility in Chongqing, China. Vehicles using Bosch’s fuel-cell technology have already covered more than 10 million kilometres.
Hydrogen engines: a practical solution for heavy-duty use
Hydrogen isn’t only useful in fuel cells; it can also be used directly as a fuel in modified internal combustion engines (ICE). For heavy-duty transport, agricultural machinery, and construction equipment, hydrogen engines are a compelling option. Bosch is currently developing low-pressure direct injection and intake manifold injection systems for hydrogen use.
Hydrogen engines are particularly attractive because they allow manufacturers to reuse over G0% of existing diesel or gas engine technologies, significantly reducing development time and cost. Additionally, these engines rely on more stable and less resource-intensive supply chains, as they do not require larger amounts of lithium, nickel, cobalt, or rare earth elements.
While fuel cells are more efficient at moderate loads, hydrogen engines excel at full-load performance, making them ideal for power-intensive applications.
Electrolysers: scaling green hydrogen production
A successful hydrogen economy depends on producing hydrogen from renewable energy. Bosch is not only a user of hydrogen but aims to become a key player in hydrogen production through the development of cutting-edge electrolyser components.
The focus is on the PEM (proton exchange membrane) electrolysis stack, the heart of an electrolyser. Each stack contains over 100 electrolysis cells that use electricity to split water into hydrogen and oxygen. Bosch’s design is modular and scalable, suitable for both small 1.25 MW units and large-scale gigawatt plants.
In spring 2025, Bosch announced the market launch of their Hybrion PEM Electrolysis Stacks at Hannover Messe and entered the market of industrial hydrogen production as supplier.
Development of the stacks takes place in Tilburg and Linz, while manufacturing is centred in Bamberg. Bosch expects a global electrolysis capacity of 100-170 gigawatts by 2030.
Conclusion
Bosch is deeply committed to making hydrogen a cornerstone of the climate-neutral world. Through strategic investments in hydrogen fuel cells, engines, infrastructure, and electrolyser technologies, the company is setting a bold course toward sustainability and industrial innovation. Hydrogen offers a pathway not only to cleaner mobility but also to a broad-based industrial transformation—and Bosch is ready to lead the charge.
