Batteries require destroying the environment for heavy minerals for their construction and environmental problems for their disposal.
Fuel cells are better than batteries *if* you have the infrastructure to deliver the fuel. We're using batteries right now because we already have the infrastructure (the grid). The grid can become greener over time, but as you mentioned I think that needs a lot of (modern tech) nuclear to get where they claim they want to be.
