Sort of, but they still have batteries (though less). And now you have a hydrogen fuel cell disposal problem, and it's not clear to me whether that is better or worse, and if it's better, whether it is worth the greater complexity and inherent inefficiency of H2 production, whether it is grey H2 or green H2

That's a big if considering that we already have an electric vehicle charging infrastructure and that can charge your vehicle in a zero carbon way in many places.
- _hypx 4y agoA hydrogen fuel cell is 100% recyclable. It is basically analogous to a catalytic converter.
- danans 4y agoBatteries are also recyclable, and also have extended use cases after their use in cars and before they are recycled (mostly as distributed stationary grid storage).
- _hypx 4y agoNot really. Li-ion batteries are very poorly recyclable. Not to mention it is rarely done right now.
- danans 4y ago> Li-ion batteries are very poorly recyclable. 95% recyclable [1]. And there are 3 separate companies I know of working on it, Li-Cycle, Northvolt, and Redwood Materials. That article lists many more. 1. https://spectrum.ieee.org/amp/lithiumion-battery-recycling-finally-takes-off-in-north-america-and-europe-2652903758 https://spectrum.ieee.org/amp/lithiumion-battery-recycling-f...
- _hypx 4y agoThat's the claim, not proven. In reality, very little batteries are recycled and we recover very little of the materials. https://arstechnica.com/science/2022/04/lithium-costs-a-lot-of-money-so-why-arent-we-recycling-lithium-batteries/ https://arstechnica.com/science/2022/04/lithium-costs-a-lot-...
