The question is where hydrogen will fit into this picture.
And we're not saying hydrogen will replace every electric vehicle.
BMW reiterated that moving to hydrogen will be a long-term proposition.
His book "The Hype About Hydrogen" will be published this spring.
And in turn using energy to make the hydrogen will inevitably produce unwanted global warming gases.
To convert to electricity or, more fancifully, to hydrogen, will involve substantial retooling that will be difficult to finance.
Eventually, it is hoped, fuel cells running on hydrogen will take the place of the ubiquitous internal combustion engine.
Then the hydrogen will be used to produce synthetic natural gas, which can power internal-combustion engines.
Moreover, hydrogen will only be suitable for the mass market when there is a network of fueling stations.
Mention at your peril the possibility that hydrogen will be the fuel of this century, just as oil was that of the previous one.
In other words, claims that hydrogen will be the automotive fuel of the future are as true today as they ever have been.
