The use of storage power plants is not new to the electricity industry. To name just one example, we have been using pumped-storage plants for decades. However, the operating conditions for these very plants have changed. In the past, the rule of thumb was that electricity prices were high during the day and low at night. This reflected the laws of supply and demand. But as renewable sources of energy are increasingly being fed into the grid, such rigid rules no longer apply. And this is why today's storage systems must be far more flexible. In light of the transition to renewable sources of energy, continuing work to further to develop storage technologies thus makes sense. This applies to everything from advanced battery concepts and compressed air reservoirs to redox flow batteries, flywheel energy storage, and superconducting coils.
