That doesn't seem worth it when you can fit that amount of storage in about 20 L with lithium ion cells (think a small PC case), or something like 40 L if you used sodium ion cells, which are looking like a new alternative.

Concrete offgassing of CO2 is already a big contributor to greenhouse gasses, so I can't imagine this battery version is improving things there. You'd probably have to wire your whole basement with electrodes to even access the stored energy.
