Market forces will take care of this, if needed. If battery price goes up, hydrogen vehicles are favored. What hydrogen vehicles need now is cheaper catalysts for their fuel cells.

Hydrogen-powered vehicles are much, much lighter than battery-driven, so consume less energy in operation. Balanced against that, electrolysing hydrogen has some losses, and braking doesn't regenerate hydrogen you used.

I would already call them staggeringly high.

«In 2016, studies found that the cost of a typical EV battery replacement could reach $10,000 or more» (from Autoweek).

But prices have fallen sharply in recent years, and may continue on down. 2016 is two generations back, in battery years.

Probably future decreases will come from better power density, requiring less physical material for a given capacity, as demand for materials soars. It is remarkable how little lithium there is in a typical Tesla.

This is the bamboozle argument that Tesla's been pushing since 2013 model S, while hiding the true cost with the warranty.

A decade later, replacement pack for that car still runs you ~$20k, which makes model S cars disposable when they roll off the subsidized warranty.

Battery cost per unit of energy stored has fallen very fast for years.

What Tesla charges to replace batteries is a whole other matter. They charge what they think they can get.
