What are the common energy storage technologies at present?

Regent understands that pumped storage, electrochemical energy storage, supercapacitors and so on are common at present.

Pumped storage is a kind of energy storage technology, which uses the electric energy when the power load is low to pump water to the upper reservoir, and then releases water to the lower reservoir at the peak of the power load. This is the most mature energy storage technology at present, with low energy storage cost and large-scale application.

Electrochemical energy storage is the most advanced energy storage technology. In recent years, electrochemical energy storage technologies such as sodium-sulfur battery, flow battery and lithium ion battery have developed rapidly and have great development potential. If breakthroughs are made in battery materials, manufacturing technology, system integration, operation and maintenance, the future development prospects will be broader.

Supercapacitors were developed in 1970s and 1980s. It stores energy by polarizing the electrochemical components of electrolyte, and there is no chemical reaction in the process of storing energy. Because the energy storage process is reversible, supercapacitors can be repeatedly charged and discharged hundreds of thousands of times. However, due to the small energy storage capacity, it is not suitable for large-scale energy storage in the power grid. Mobile energy storage is used with Regent container air conditioner, and the effect is better.
