BMW was one of many first automakers to experiment with hydrogen, starting within the late Nineteen Seventies. It began with a 5 Collection (E12), developed in collaboration with the German Aerospace Analysis Institute. The 520h retained a combustion engine tailored to run on each gasoline and hydrogen. Subsequent prototypes additionally burned gasoline. There was a 7 Collection (E23) in 1980, one other 7er (E32) in 1988, adopted by the better-known 750hL (E38) in 2000, powered by a mighty V12.
The V12-powered Hydrogen 7 (E65) is essentially the most recognizable BMW hydrogen automobile, though the H2H Report Automobile additionally garnered consideration with its twelve-cylinder engine. Nonetheless, it has been a very long time for the reason that German luxurious automaker moved away from hydrogen-powered combustion engines, shifting focus as a substitute to gasoline cells. Why the change?
Juergen Guldner, Normal Program Supervisor of Hydrogen Know-how, defined BMW’s deal with gasoline cell hydrogen to Driving Hydrogen journal. He cited packaging constraints, noting {that a} combustion engine occupies important area beneath the hood: “Given restricted area in passenger autos, this makes gasoline cells the good selection (in comparison with ICE).” Whereas he acknowledged {that a} combustion engine may make extra sense in a truck, he emphasised that gasoline cells are the popular answer for vehicles.
Effectivity additionally performed a major position within the resolution. BMW deserted hydrogen combustion engines as a result of gasoline cells supply “about two-thirds extra vary in comparison with combustion.” Refueling occasions are comparable, with Guldner stating your complete course of takes simply 3–4 minutes.
Apparently, Guldner didn’t completely dismiss the concept of a high-performance M hydrogen automobile with a combustion engine. Whereas engineers aren’t at present creating such a powertrain, it stays a risk: “We’ll see what the longer term holds.”
However why is BMW pursuing a hydrogen automobile in any respect? Scheduled for a 2028 launch, the upcoming mannequin is broadly anticipated to be the iX5, primarily based on the next-generation X5 (G65) that’s set to reach subsequent 12 months. Guldner argues that battery-powered EVs aren’t appropriate for everybody, primarily as a result of underdeveloped charging infrastructure.
A hydrogen automobile additionally makes use of fewer uncommon earth components in comparison with a traditional electrical automobile, lowering environmental pressure. The mass adoption of battery EVs will drive up demand for lithium and cobalt, whereas gasoline cells are much less resource-intensive.
BMW is assured that its 2028 hydrogen automobile, developed in partnership with Toyotawill probably be as secure as any mannequin in its lineup. Guldner additionally claims hydrogen refueling is “easier and cleaner than filling up with petrol,” providing one other clear benefit.
That stated, the corporate’s first hydrogen mannequin is unlikely to be accessible globally. As of 2024, there have been solely simply over 1,000 refueling stations worldwide. The iX5 will seemingly be offered in California, the place Toyota has provided the Mirai for years, albeit with restricted success.
Regardless of the infrastructure challenges, BMW believes “the timing is correct.”
