I’ve seen debates on the gravity batteries before, and while they certainly work, I doubt they will really displace significant amounts of lithium battery usage. For one, sodium batteries are already a thing and much more likely to replace lithium. The biggest drawback with sodium batteries (lower energy density) is not a problem for grid applications.
Even more importantly, with how fast the industry is growing, by the time new solutions are scaled up for mass adoption, large amounts of new lithium battery storage will have been installed already. Although installing 25 MW of new battery capacity with one project is nice, we need 1300 ish GW of new batter power capacity by 2030 to support enough renewable generation. It will take a lot of projects, very large projects to fill significant amounts of that capacity with gravity storage.
Of course, that’s not to undermine the fact that this is definitely a step in the right direction.

Username checks out. What do you think of calcium batteries?
I don’t think of calcium batteries. I’m not a battery engineer T_T
what is your take on vanadium flow batteries
I’ve never heard of those before o_o
It’s all going to depend on what offers the cheapest lifecycle cost for a particular use case I imagine.
