Hi,
Whats the cutting edge in lowest cost per kwh of 'cycled energy' storage these days ? ie the cost of 1khw storage / cycles in a liftime ?
SLA are quite cheap, but dont last so long, nicad more expensive but probably more cycles, Im not sure about the other types lithium etc, as theyr not readily available off the shelf so hard to get a good cost to compare, maybe super cap?
I had a crazy idea to work out economics of storing electricity at cheap rate and be able to use it during the day. plus it would be a good ups.
A water tower might be good if there was one handy.
