There's no likelihood of batteries scaling to certain uses, such as large long-distance air transport, or marine shipping. Most trucking as well.

We either stop using those transport modes, or revert to prior forms (wind), or wire-based electrical systems (rail, canals, trucks).

Or make fuel. There are all sorts of ways to make carbon neutral diesel and jet fuel. They just aren't economic compared to pumping it out of the ground unless the externalities of burning virgin fuels are priced in with regulation.

Good point. I've been excited by fuel synthesis technologies, though they've proved difficult to develop at scale.

A Google X Project tried and failed.
