Key facts
- Hydrogen combustion engines are being developed as a cheaper alternative to fuel cells.
- Development spans various mobility devices, including generators and sports cars.
- Widespread adoption of hydrogen fuel could be boosted by this technology.
Hydrogen-fueled combustion engines are gaining traction as a lower-cost alternative to fuel cells, with development in a broad range of mobility devices a potential tailwind for widespread adoption of the environmentally friendly fuel. Kawasaki Heavy Industries and Toyota are among the companies developing these engines, with Kawasaki focusing on smaller units than its six-cylinder model. The technology's potential application in generators and sports cars suggests a diverse range of uses that could accelerate the uptake of hydrogen.
