Does anyone know if large scale capacitors are being investigated for this sort of application (or in home storage)? Strikes me as more appropriate than batteries; don't really need to store that energy for months, but rather hours or days. I know that Tesla utilises economies of scale, but still curious why I've never heard of large scale capacitors even being researched.

The Energy density of capacitors is very low (10-100x less than lithium) and they cost quite a bit more per watt-hour. Capacitors are good if you need power for seconds rather than the minutes-hours that batteries are good at.
