Kawasaki have taken their hydrogen internal combustion engine motorcycle project to the next stage by running a prototype machine at a test track. We first saw renders of an H2 SX-based concept...
A Toyota Conglomerate Group is currently developing an Automotive Hydrogen Generator for an ICE Propulsion System, so that large pressure-vessel on-board storage is not needed, (i.e. unlike the original Hydrogen Combustion Engine design that Ford bought out and buried in the 40's).
IMHO the Automotive Hydrogen Generator/ICE will make the EV Vehicles a thing of the past.
