Robin Harding and Kana Inagaki writing for the Financial Times:
...for reasons of industrial strategy, energy security and physics, Japan and its biggest carmaker [Toyota] are placing a huge bet on hydrogen. Come the 2020 Tokyo Olympics, they want fleets of fuel cell cars and buses taking athletes from village to venue, before the vehicles head for the global mass market.
Now for the bad news:
The technology is expensive: a petrol-powered vehicle at a Toyota plant rolls off the production line every 60 seconds but it currently takes 72 minutes to assemble a single Mirai. It needs a nationwide refuelling network that does not exist anywhere.
And it just keeps getting worse:
There are no natural hydrogen deposits on Earth. You cannot dig for it, drill for it or harvest it. You have to make it. That uses energy, which is why Elon Musk, Tesla’s chief executive, dismisses hydrogen vehicles as a “mind-bogglingly stupid” industrial dead end.
