1) lithium mining is up 6x since 10 years ago. You shouldn’t assume the average over ten years is a good indicator about capacity to mine. Mining rates are growing quickly. 2) there are competing materials for new battery tech besides lithium 3) battery capacity deployed per year is growing exponentially 4) when you have large over supplies of energy you can pursue hydrogen. Green hydrogen should be at parity with grey hydrogen in less than a decade. Not cost competitive with just using fuels or batteries for utility scale, but slowly getting there. 5) commercial viability absolutely matters. Subsidizing an expensive source of energy rather than building more and more capacity for cheap energy is a bad strategy while using fossil fuels as a crutch in the interim is a bad strategy. Running a nuclear plant at low capacity craters its financial viability. |

> there are competing materials for new battery tech besides lithium
And which of those are mass-production ready and are being deployed? Maybe one day, one of them will. Until such time, this argument is about the situation as-is.
> when you have large over supplies of energy you can pursue hydrogen.
The over supply would need to be truly enormeous, because Hydrogen is a cryogenic gas. It needs to be pressurized and cooled, both of which requires a constant expenditure of energy which is lost as usable power. It also carries [safety risks][1], and is [infamously hard to keep under control][1].
> commercial viability absolutely matters.
Long term, preventing climate change matters more. Alot more.
