Yeah, so would cheap nuclear power or cheap batteries. I find cheap batteries way more likely then either of those.

- partiallypro 4y agoI think the current problem with batteries is that it presents a geopolitical risk that is akin to (maybe worse than) oil.
- UncleOxidant 4y agoThere are lots of efforts in creating battery chemistries that do not rely on hard to source elements. Lithium sulfur (no cobalt required), Sodium ion (much more readily available than Li), and many other efforts - some showing good results.
- freemint 4y agoUnlike oil once there are enough batteries in a country that country is good for a long time as a batteries can be recycled quiet well (lead acid batteries have a recycling rate of 99.99x%, it is just a question of political will and new batteries being cheap right now).
- ortusdux 4y agoHydrogen is a battery. We have no free source of H2. We have to put energy into making it, storing it, and transporting it. We get less energy back than we put in. The most generous lifecycle analyses that I have seen estimate 60-70% roundtrip efficiency.
- ncmncm 4y agoPumped hydro is often no better. 60% is plenty, if electricity is cheap enough. And it already is.
