Storing excessive thermal energy to be used in colder times is one of the oldest forms of energy storage known to us. Recent research and development have made it possible to use this energy for grid applications. Learn more about the different types of thermal energy storage here.
Since the electrical grid has existed, so has the need for stored forms of energy that can be drawn on to meet times of peak demand and regulate frequency. In the past, the bulk of this extra energy came from fossil fuel plants that were fired up and down with demand.
Are energy storage systems profitable? How does their value relate to their costs? How will this change in the near and long-term future? Learn more about the economics of energy storage and the business case for these solutions.
