I know electric vehicles are what consumers want, but how come there has not been a push for cars running hydrogen fuel cells? Besides the issue with hydrogen being flammable, are there any other concerns automotive companies have about it?
Gasoline is flammable and is used with little concern by drivers everywhere. Even the battery powered vehicles are not exempt from bursting into flames. I don't think flammability is an issue that should detract from the adoption of hydrogen.
I think the lack of hydrogen powered cars can be attributed to two factors:
Lack of infrastructure
Little market interest
Liquid fuels (gasoline, diesel, kerosene), and electricity have a nationwide/worldwide infrastructure working right now. Hydrogen filling stations may be available in some areas, but they are uncommon.
Who will buy the hydrogen cars? I'm all for research and development, but before production can begin, there needs to be customers. If a consumer were to decide between an electric, a hybrid, and a hydrogen powered vehicle, why would they choose hydrogen?
