Novel Approaches to Utility Energy Storage

Energy Storage


Storage has emerged as a key component in the vision of the smart grid. A number of start-ups are developing technologies they hope can address a specific storage application.  Some alternative storage technologies that hope to become utility scale include:  compressed air, flow batteries, and flywheels.

The advantage of underground compressed air storage is that it can be cheaper than batteries and can store many hours worth of energy. Another novel technique is using metal tanks to store compressed air. The compressed air is released to run a hydraulic motor that drives a generator to make electricity. Flow batteries use tanks of liquid electrolyte solutions. When the two liquids interact, there is a chemical reaction that creates a flow of electricity. An advantage of this approach is that store large amounts of energy and discharge relatively quickly.
