The planned investment was one billion euros (RM5.1bil) more than earmarked in its previous investment plan for 2021-2024, the statement added.
Vehicles with hydrogen fuel cells, in which hydrogen mixes with oxygen to produce water and energy to power a battery, can refuel in minutes and have a much longer range than battery-electric vehicles, but infrastructure is lacking and it is less energy-efficient.
Bosch expects one in five new trucks weighing six metric tons or more would feature fuel-cell powertrains by 2030, it said.
"Bosch is growing with hydrogen," said chief executive Stefan Hartung.
Bosch said production of its fuel cell power module - a fuel cell system generating electricity in vehicles from hydrogen, primarily used in commercial long-distance applications - has begun in its Stuttgart-Feuerbach plant in Germany and in Chongqing, China.
Nikola Corporation will be the pilot customer of the modules made in Stuttgart-Feuerbach, with the Class 8 hydrogen fuel cell electric truck to enter the North American market in the third quarter of 2023.
Daimler Truck plans to bring a hydrogen truck to market in the second half of the decade, forming a joint venture with Volvo to develop the zero-emissions technology.
Automaker Stellantis said this year it would begin deliveries in Europe of its first medium-sized vans powered by hydrogen fuel cells by the end of 2021.
By contrast, Volkswagen subsidiary Traton is focusing exclusively on battery-electric development.
