They say you don’t need to be a rocket scientist to answer most questions, but on the subject of the potential of hydrogen to fuel internal combustion engines, I’ve turned to one.

So let me acknowledge the direct help of David Peilow in creating this column.

The spark for it came from the announcement that Toyota and Yamaha had teamed up to modify the Lexus RC F’s naturally aspirated 5.0-litre V8 to run on hydrogen.

Its creators talked enthusiastically of its five-year development cycle to date, engaging sound and performance and the potential for the technology to be applied to production cars and bikes in the future.
