BMW debuted a pilot hydrogen-fueled car based on Toyota fuel cells.

The iX5 Hydrogen debuts in a fleet of fewer than 100 that will be used in demonstrations and trials for “various target groups.”

BMW said the introductory phase will result in “valuable knowledge” and build toward possible series production.

“Hydrogen is a versatile energy source that has a key role to play in the energy transition process and therefore in climate protection,” said Oliver Zipse, chairman of the BMW AG board of management, in a press release introducing the iX5.

“After all, it is one of the most efficient ways of storing and transporting renewable energies. We should use this potential to also accelerate the transformation of the mobility sector.”

BMW isn’t abandoning electric models but presents hydrogen as another alternative fuel in a non-gas-powered future.

“Hydrogen is the missing piece in the jigsaw when it comes to emission-free mobility,” Zipse said.  “One technology on its own will not be enough to enable climate-neutral mobility worldwide.”

BMW said it and Toyota have collaborated on fuel cell drive systems since 2013. It uses Toyota’s fuel cells to make fuel cell systems for the pilot model in Munich, where it also builds the vehicle itself.

The German automaker said hydrogen makes for fast refueling of a vehicle, from three to four minutes. It says the iX5 has a 313-mile range.

Other carmakers are also exploring hydrogen fuel technology, including General Motors, Toyota and Hyundai.
