Aside from storing energy from a large array in the desert, won't we still need batteries for transportation in order to get them off fossil fuels? That is, even if my house runs off nuclear and hence no batteries, wouldn't I still need one in my car, hence a lot more innovation is needed in batteries anyway (albeit drastically different types of batteries)?
- jabl 8y agoLike I mentioned in an answer to a sibling comment of yours, I didn't mean to say that we're at the end of the road for battery development today. Just that we cannot expect decades of exponential improvement like we have seen with microchips. I don't think an order of magnitude improvement in price/kWh is out of the question (in terms of kWh/kg it probably is, though?). But two orders of magnitude? Color me skeptical. Wrt cars, I think batteries are not too far from being viable to replace most uses in cars, city buses etc. And that will be a massive, and welcome change, in our society. For long-range ships, planes etc. I don't see batteries as viable. My guess would be, for a future decarbonized society, synthetic hydrocarbons for planes and ships; some ships might use hydrogen or nuclear reactors.
