- Overview

Wind and solar are intermittent, generating electricity when available rather than needed, so the green energy transition will require significant energy storage. This could eventually take many forms, from traditional lithium-based "big battery" devices, to flow batteries, silicon phase change batteries, molten salt batteries, iron-air batteries, gravity batteries, carbon dioxide expansion batteries and other more unusual batteries Ideas like buoyancy batteries. 

Each method has its own advantages and disadvantages in terms of efficiency, size, location, installation costs, operating costs, input and output power ratings, lifespan, and how long the energy can be stored. This is good because different solutions will meet different needs - some support the grid during transient demand peaks, others remove the daily curve of mismatch between demand and renewable energy supply, and some still have Helps with seasonal supply declines, such as through winter when solar is down.

High-voltage power electronics, such as switches, inverters, and controllers, allow precise and rapid control of power to support long-distance transmission. This capability will allow the system to respond effectively to disturbances and operate more efficiently, reducing the need for additional infrastructure.


- Energy Storage Technology 

One of the distinguishing features of the electricity industry is that, although electricity demand fluctuates throughout the day, the amount of electricity that can be produced is relatively constant over short periods of time. The development of technologies to store electrical energy so that it can be met when it is needed will represent a major breakthrough in power distribution. 

To help achieve this, energy storage devices can manage to provide customers with the power they need when demand is greatest, i.e. during peak loads. These devices also help make renewable energy sources whose power output cannot be controlled by grid operators smooth and dispatchable. 

They can also balance the microgrid for a good match between generation and load. Storage devices can provide frequency regulation to maintain a balance between network load and power generation, and they can enable more reliable power for high-tech industrial facilities. Therefore, energy storage and power electronics hold great promise for transforming the power industry. 

As energy storage technology can be applied in many fields with different power and energy requirements. This broad technology base includes batteries (conventional and advanced), flywheels, electrochemical capacitors, superconducting magnetic energy storage (SMES), power electronics and control systems.
