I've seen articles similar to this many, many times over many, many years, but we're still using the same battery tech as ever. Breakthroughs are good and all, but don't go ranting and raving too hard about this stuff unless it becomes viable and practical enough for either consumer or industrial applications, preferably both.
Ehhhh battery tech has been advancing quite a bit lately as we (thankfully) move away from lithium-based batteries. Grid-scale installations use a variety of battery tech these days with constant improvements being made to them. Liquid metal batteries, salt batteries, flow batteries, etc there are a lot of new options being used and developed.
On the more consumer-focused end of things, LFP batteries have surged in popularity due to their lower cost, higher reliability, and longer life. NMC batteries are also sued in some EVs. We probably won't see a replacement to lithium ion cells for consumer electronics for a while because their power density per size/weight is so good but R&D is still making progress with alternative technologies.
Ambri is already broke.
Yeah, for gridscale power in areas without enormously expensive land prices, cheap might beat out dense in terms of battery tech usability. Lithium is still best for applications that require energy density (EVs) but for grid storage I can see bulky, cheap, resilient/reliable batteries make more sense as a long-term investment.
Pump water up a hill during sunlight.
Just requires a hill that is big enough, two basins that can hold the water, and then of cause we need all the water.
