I don’t know if it’s totally dead in the automotive sector either, the Hyundai N Vision 74 for instance has both a hydrogen fuel cell AND a battery. That was a pretty cool solution IMO since you have them both offsetting the weaknesses of the other. Might be a bit pricier in a consumer vehicle, I’m not sure, but pretty cool idea anyways.

I can confirm they work well, I’ve used them through several Canadian winters and they’re quite warm. The tricky part is that cheaper ones can start to unravel along where the flap attaches to the rest of the glove. So probably worth buying from a good brand.
