Economies of scale and improved manufacturing methods are driving high energy storage prices down -- and fast!
Calcium is about 2,500 times as abundant as lithium in nature, making the calcium-ion energy storage technology a promising candidate ...
I mean, it's a pretty solid method.
At $100/kWh stored wind and power becomes competitive with conventional power.
And charge up using daylight. Elegant!
