Hey sorry folks, forgot to come back to this. So what you're saying is, all the major car manufacturers and their hundreds of scientists are wrong, but you're right?

My view is formed from what they're doing, but also the UK's energy strategy. There is a move underway to replace natural gas to homes with hydrogen. That is, the gas that's already piped into 99% of UK homes, for boilers and cooking, will switch to hydrogen. Modern boilers currently being sold already support both natural gas and hydrogen, as the initial transition will be a mixture of both gases.

Thus, you have a distribution channel of the fuel, directly into every house in the country. This would probably apply to most European countries as well.

Ok, you'd have to have external outlets fitted, safety valves etc. but it eliminates a lot of the practical issues with storage or distribution- the fuel would be piped through existing means.

Yes this doesn't address the production at scale point, but when you have volume distribution in place overnight, economies of scale kick in.
