German auto supplier Bosch will invest almost 2.5 billion euros ($2.8 billion) in hydrogen fuel cell technology from 2021 to 2026 and expects to generate roughly 5 billion in sales from it by 2030, the company said on Thursday.

The planned investment was one billion euros 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.
