Despite the electric vehicle (EV) trend, internal combustion engines are still relevant, especially for high performance. Hydrogen combustion engines are emerging as a viable alternative due to challenges faced by EVs. AVL Racetech in Australia has made strides with a 400-horsepower hydrogen engine that operates at 6,500 RPM, featuring a water injection system to control combustion and enhance power and torque. This innovation has potential applications in motorsports, with plans to introduce hydrogen-powered engine prototypes by 2027. Hydrogen combustion cars address EV challenges by offering quick refueling, lightweight performance, zero carbon emissions, and the traditional engine sounds that driving enthusiasts appreciate. The rise of hydrogen combustion engines is not limited to AVL Racetech; companies like Toyota and Yamaha are also investing in hydrogen technology, hinting at a future where hydrogen-powered cars could become mainstream.
