We've known that Yamaha is keen to experiment with hydrogen as an alternative fuel for several years. In January 2022, Team Blue announced plans to work with Kawasaki on hydrogen engine development. Then, a month later, we learned of plans to work on a 5-liter V8 hydrogen engine with Toyota.
By July 2023, Yamaha president Yoshihiro Hidaka reiterated the company's commitment to exploring hydrogen development as a viable alternative fuel source. And of course, with the 2024 Dakar Rally very recently in the history books, we can't forget about the HySE experimental rally vehicle that Yamaha (along with Honda, Kawasaki, Suzuki, and Toyota) had a part in building.
