This is not too bad. I'd prefer hydrogen fuel cells over massive toxic batteries that we're going to have to dispose safely in a few years, from all those used Teslas! I don't know about other countries, but most of the electricity generated here in Australia is from Coal and Natural gas. That's an unfortunate fact. I don't see any reason to buy an electric car until that changes. In the meantime if the solar driven hydrogen production efficiency increases then we can have an even cleaner future.
