We don't expect the wind and solar naysayers to give up any time soon, but new utility-scale energy storage solutions are beginning to come on line, and they will put to rest this whole notion that intermittent energy sources (namely, wind and solar) can't provide a significant … During piston strokes, water is sprayed into the air-filled chamber of each cylinder, allowing heat to be transferred from water to air during expansion or from air to water during compression.
