Today in Cleantech

Last week we delved into the world of standards for solar power systems — this week, it’s time for energy storage to get the standards treatment. The IEEE has formed a working group in its P2030 smart grid interoperability group, aimed at giving makers of energy storage systems some guidelines for how they should communicate and interact with the grid. As batteries become less expensive, they could be deployed in a smaller-scale distributed fashion to  help firm up local grids. At the same time, alternate storage systems such as flywheels or thermal energy storage (i.e. ice-making air conditioning) are likely to be integrated with batteries, inverters and ultracapacitors in ways that could challenge traditional grid controls.
