Here’s one electricity storage technology that’s been around for over 20 years, under the radar, but might be due for a resurgence in interest with the addition of more wind power to the grid. Wind tends to blow at night when we don’t need it.

Steffes Electric Thermal Storage makes devices that store excess off-peak renewable electricity very simply, as heat, by heating up electric coils surrounded by ceramic bricks in a sealed container. The ceramic bricks are thermal sinks. They soak up the heat slowly, and when triggered to, can release that heat, just as slowly, providing low-cost heating.

Excess electricity generated can be stored at any time, like at night from excess wind power, and then released at any time it’s needed; on demand, in the form of heat.

Because it is useful for businesses and homeowners, it is distributed energy storage.

The technology sounds ultra-futuristic: concentrated solar heat that can vaporize biomass (wood, crop waste, etc.) into synthetic fuels. But the process, developed by Sundrop Fuels, is real, and it can produce twice the amount of gasoline or diesel than conventional biomass gasification systems.
