Energy storage is needed for electrical grid peak loads. There's been a lot of pie in sky stuff out there... flywheels, fuel-cells, battery banks.

It was nice to see someone with a real solution. Ice Energy does HVAC units that freeze water at night, then uses this as an energy sink during the peak electrical load. hours. This works so well because they're taking advantage of the heat-of-fusion (energy needed to melt) of water. A very non-BS thing. In fact, the definition of a ton of HVAC came from the ability to freeze a ton of water in 24 hours.

They had a little booth there with a unit that was slowly melting a 7000lbs tank of ice.. running a little multi-split, keeping their booth-guy a little cooler and a little happier than the other booth people at the show."
