What are the five underground large-scale energy storage technologies?

In this work, the characteristics, key scientific problems and engineering challenges of five underground large-scale energy storage technologies are discussed and summarized, including underground oil and gas storage, compressed air storage, hydrogen storage, carbon storage, and pumped storage.

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.

What are underground energy storage systems?

This paper clarifies the framework of underground energy storage systems, including underground gas storage (UGS), underground oil storage (UOS), underground thermal storage (UTS) and compressed air energy storage (CAES), and the global development of underground energy storage systems in porous media is systematically reviewed.

Can deep underground energy storage be developed in China?

The solution to these key scientific and technological problems lies in establishing a theoretical and technical foundation for the development of large-scale deep underground energy storage in China. 1. Introduction China must urgently transition to low-carbon energy consumption in order to meet the challenges of global warming.

Why is underground gas storage important for China's Energy Security?

Therefore, accelerating the construction of underground gas storage is an important strategic demand to ensure China’s energy security. Based on the above analysis, the use of deep underground spaces for large-scale energy storage is one of the main methods for energy storage.

What are the different types of underground energy storage technologies?

For these different types of underground energy storage technologies there are several suitable geological reservoirs, namely: depleted hydrocarbon reservoirs, porous aquifers, salt formations, engineered rock caverns in host rocks and abandoned mines.
