Japan has taken a significant step towards creating an ecological motorcycle of the future, with an engine cooled by water through internal hydrogen combustion for small vehicles. This innovative approach is part of the country’s efforts to reduce its reliance on fossil fuels and decrease carbon emissions.
Electric motorcycles? Know the prototype that burns water, propelled by hydrogen
Motorcycle manufacturers worldwide are facing a dilemma. It’s becoming increasingly clear that internal combustion engines fueled by fossil fuels are on their way out, and there’s growing pressure to set a deadline for their replacement. One option is electric motorcycles, which have proven technology and a rapidly growing support network. However, for two-wheelers, the story is different. Motorcycles need to be light and compact, and currently, no battery technology can offer that.
On the other hand, hydrogen energy could be a more feasible way to store and transport energy than electricity. That’s why Kawasaki is focusing on hydrogen to create the future motorcycle. Although they had already revealed the first “air engine,” they’re now part of the Japanese Hyse coalition (Hydrogen Small Mobility and Engine), working alongside Honda, Suzuki, and Yamaha to make internal hydrogen combustion engines for small vehicles a viable path for the future.
The interest in hydrogen isn’t limited to saving the planet; burning hydrogen produces exhaust emissions that are almost entirely water vapor. These companies have huge manufacturing bases and supply chains dedicated to internal combustion engines, making this a crucial development for their future.
This is the first motorcycle driven by Japan hydrogen
The Ninja H2 Hyse will be the first full-size motorcycle driven by hydrogen, and it’s by far the most important development, not only for Kawasaki and its goal of a future with zero carbon emissions in 2030 but for motorcycling as a whole. The motorcycle features a 998 cc four-cylinder engine that binds to an in-house manufacturing compressor, with modifications made to allow direct hydrogen injection in cylinders instead of gasoline. A six-speed transmission, with chain transmission, allows efficient power supply to the wheel, while the exhaust is a four-unit-in-one system.
Like the engine, the structure is derived from the H2 platform, with reminiscences of the H2 SX clear in the star-shaped wheels, disc brakes, mockery, and tangled chassis. However, Kawasaki says that the chassis has been reinforced.
When will the official launch of this motorcycle of the future be?
Although the motorcycle prototype has not yet been in action, the H2 motor fed with Kawasaki hydrogen will be tested when the HYSE-X1 four-wheeled vehicle, developed by the Hyse Association to demonstrate and test its technology, competes in the Dakar Rally. It’s expected that the motorcycle seen here will begin to submit shortly after, but it’s likely to take several years before a production version arises. An innovation like this engine, which cools with water, could be the future of hydrogen-powered vehicles.
The Hyse prototype will debut in a few years, but unfortunately, the wait will be much longer. Kawasaki states that its goal is to manufacture a motorcycle with an internal hydrogen combustion engine that works as a neutral carbon option for enthusiasts by early 2030. Even considering the best possible scenario, that’s still six years away.
