What is the concept of ultra-large capacity energy storage

Why is energy storage important?

Energy storage is one of the most important technologies and basic equipment supporting the construction of the future power system. It is also of great significance in promoting the consumption of renewable energy, guaranteeing the power supply and enhancing the safety of the power grid.

What is long duration energy storage?

Long duration energy storage offers a superior solution. It complements transmission and renewables, moving energy through time to when it’s most needed. It reduces the total infrastructure we need to build, lowering costs and customer energy prices. There are many forms of energy storage.

Will large-scale energy storage technologies play a vital role in China's future energy system?

Therefore, massive demand is anticipated for the implementation of large-scale (especially underground) energy storage technologies (Fig. 1 (b)), which will play a vital role in China’s future energy system. Fig. 1. (a) Electricity structure of China in 2021; (b) comparison of various energy storage technologies.

What is long-duration electricity storage (LDEs)?

Long-Duration Electricity  Storage (LDES) refers to energy storage systems that can store and release electricity for long periods, typically eight hours or more. These systems help balance the supply and demand of electricity, especially when using renewable energy sources like wind and solar, which can be unpredictable.

What technologies can be used for energy storage?

Other technologies include liquid air energy storage, compressed air energy storage and flow batteries, which are currently in development and would benefit from investor support. Large scale storage provides the grid with both security and flexibility to dispatch electricity to manage seasonable peaks or low renewable output over a period of time.

What is the future of energy storage?

Looking further into the future, breakthroughs in high-safety, long-life, low-cost battery technology will lead to the widespread adoption of energy storage, especially electrochemical energy storage, across the entire energy landscape, including the generation, grid, and load sides.
