Good points Siko. The bottom line is that Hydrogen fuel can't and won't be "green" anytime soon unless we use nuclear power to drive extraction processes. From what I understand, with todays technology, you'd be paying roughly $10.00 a gallon to buy green hydrogen fuel.

However, I don't thumb my nose at the Hydrogen 7. The Hydrogen combustion engine represents a solution that comsumers want, and specifically, an experience that BMW's clientele would prefer over any other process. It's very BMW of them to develop this engine, and good for a strong premium brand like them to take the lead.

Hydrogen fuel cell and electric is a future we might need, but Hydrogen combustion is the future car enthusiasts definitely want.
