The problem with this article is that it paints batteries as the nirvana of energy storage, when they are not, and never can be. The dominant player in transport is air transport, as far as energy consumption goes, so its air transport that really matters. As for large capacity land batteries, those also are not required, after aerospace gets the energy it needs to keep it airborne, the spin-offs on land based energy storage will eclipse what is currently the spin-off of batteries used effectively in domestic car transport.
