Well I’d like to add that Ford did too indirectly and it works. I personally rode both a fuel cell bus and one with a Ford Hydrogen combustion engine and both worked wonderfully. The hydrogen was sourced from electrolysis at a wind turbine. It was a proof of concept. And most relevantly… Toyota is at this again. It actually never quit because it is a smart move. Hydrogen can be easily had from natural gas or water and natural gas or oil is already the normal fuel. So you start at normal, then you switch when normal is gone. It’s expensive but let’s remember, Japan is an island with no oil deposits and a ton of smart people. Ofcourse they would try to figure it out.
