Technical FAQs 4

Is underground energy storage system a resilience enhancement method?

As an important support technology of renewables, energy storage system is of great significance in improving the resilience of the power system. In this paper, a resilience enhancement method for power systems with high penetration of renewable energy based on underground energy storage systems (UESS) is proposed.

Why do energy storage systems need underground space?

First, underground space can provide a stable and ample operation space for the energy storage system, protecting the devices from the impacts of extreme weather like rainstorms, typhoons, and blizzards (Zhang et al., 2021).

What is deep underground energy storage?

Deep underground energy storage is the use of deep underground spaces for large-scale energy storage, which is an important way to provide a stable supply of clean energy, enable a strategic petroleum reserve, and promote the peak shaving of natural gas.

Can deep underground energy storage be used for energy reserve maintenance?

Based on the analysis of the background, types and status, and the study of the key theoretical and technical problems of deep underground energy storage in China, we make the following conclusions: (1) The use of deep underground spaces for energy storage is an important direction for future energy reserve maintenance.
