I mean, you can store power in almost anything. The trick is to do it in a space-efficient, weight-efficient manner with decent longevity and decent round-trip losses.
Unfortunately, these are supercaps, which tend to be great on longevity but terrible on space/weight efficiency, and lose charge over time.
They are getting ~222uWh/cm^2 which works out to ~20Wh in 100 square feet of brick wall. Note: not kWh. Wh. 0.02kWh in 100 square feet of wall.
Now, if they can scale it up - say, by further increasing surface area while not compromising structural integrity - that'd be great.
Apparently some smart people figured out how to store electricity in bricks I swear this fuckin timeline is crazy...
Developed at Washington University, so it's racist.

Nowhere near there yet though.
