Renewable energy sources like wind and solar are here to stay, and their dominance on global electricity grids is growing every day. But for them to work, grids also need energy storage and the ability to respond instantly to fluctuations in frequency. Lithium batteries provide a lot of that functionality today, but now a new smart domestic hot water storage tank has been developed that not only heats water 20% more efficiently, but can also use electrical energy when it’s free or even negatively priced. Plus it can talk to the grid and store energy when renewables are producing too much. Edward De Bono would be proud! (look him up).
