According to her calculations, “EVs emit much less than fossil cars” even if the battery was produced in a country with an electricity mix that is 100% coal — an extreme example that does not reflect reality. Currently, the majority of batteries are produced in China, which has an electric grid that is about 60% coal, she wrote.
Fuel cell vehicles are failing because they’re not proving compelling enough.” As to the false idea that hydrogen cars are more sustainable than EVs, this is at odds with the findings of a lifecycle analysis for the UK government. This analysis found that EVs are “much more efficient” than hydrogen cars, using only a third of the energy.

Electric vehicles, or EVs, could play an important role in achieving that goal. Currently, making an EV is more carbon intensive, and expensive, than making a conventional car — largely because of the energy needed to make a battery.
Then there might be improved lithium-ion batteries, maybe using silicon anodes or rocksalt cathodes, for mid-range vehicles, or perhaps solid-state lithium batteries will take over that class. Then there might be LiS or even lithium–air cells for high-end cars — or flying taxis. But there’s a lot of work yet to be done.
Actual cars powered by solid-state batteries seem to be perpetually on the horizon: Toyota’s original target date for commercializing them in the early 2020s has now slipped to the late 2020s, for example. When it comes to batteries, “Toyota has said a lot of things in the last ten years, none of which have come through,” cautions Ceder.
