Energy storage: the next low hanging fruit?

Energy storage: the next low hanging fruit?

Energy produced by renewable sources brought a new challenge because it is not firm. In other words, the sun and the wind occur without human control!

Developed countries already include energy storage (for example via batteries) as a strategy to "mitigate" this situation that has changed, and quite a lot, the profile of the supply curve.

Initially, the effort is more focused on storage in homes. Because it is easier, simpler and does not typically require environmental licensing that would be there for large-scale systems, close to solar or wind farms.

The most interesting and convenient storage from a feasibility point of view is via cost arbitrage. When there is an excess of supply in relation to the market's demand, the batteries are charged at an off-peak price and, when peaks come, the batteries are discharged into the electric grid  at the peak price.
