Honestly I'm glad that somebody is exploring other environmentally friendly alternatives too, nothing wrong with having options.

Kind of? Hydrogen can be environmentally friendly, but EVs have big advantages:

  • Creating and burning hydrogen is way less efficient than EVs (almost an order of magnitude)
  • Hydrogen is much cheaper to create in environmentally unfriendly ways (using natural gas etc.)
  • Unless we have massive overproduction of power, the additional energy can be better used to de-carbonify other processes with larger impact

That's why generating hydrogen during off-peak hours from a nuclear power plant will be very beneficial. It may be less efficient but way better for the environment then lithium

You still have all the transport and storage costs associated with hydrogen. I'd need to see a study that actually determines the environmental impact of lithium to believe you.
