STUTTGART-FEUERBACH, Germany -- Walk through the doors at Robert Bosch's flagship factory here and the division between past and future is stark.
On the left, there is an assembly line making high-pressure diesel pumps, a staple product for a long stretch of the 114-year history at the global supplier's oldest facility.
On the right, a short hallway leads to an area where Bosch began producing hydrogen fuel cell power modules in June. Elsewhere in the same building, the world's largest supplier assembles prototypes of components for electrolyzers, industrial devices used to make green hydrogen, slated for series production within three years.
"Bosch knows its way around hydrogen," Chairman Stefan Hartung said, "and Bosch is growing with hydrogen."
The company is investing 2.6 billion euros in hydrogen technology through 2026, a development that underlines hydrogen's rising worldwide prospects as a viable clean energy source.
