Energy storage of the university of mining

Can underground space energy storage technology be used in abandoned coal mines?

The underground space resources of abandoned coal mines in China are quite abundant, and the research and development of underground space energy storage technology in coal mines have many benefits.

Should energy storage be a key issue in mining?

The second place that energy storage emerged as a key issue was less expected: in their vision of “smart” and “sustainable” mines, mining companies see advanced energy storage as a key component of the so-called “future of mining” and their vision of the “mine of the future”.

Why is energy storage a challenge in the mining industry?

The challenge, however, is that the mining industry requires an immense amount of energy storage capacity and for much longer time periods than much of the current battery technology can provide. “We are hoping that as the technology grows, [the storage capacity and duration] will increase.”

What is the energy storage capacity of a mine?

From a maximum mass limit of 1000 tonnes to a limit of 10,000 tonnes, the total energy storage capacity increases from 0.48 GWh to 2.27 GWh. The relative share of the energy capacity which is provided by mine shafts with energy capacities above 1 MWh increases as the maximum mass increases, from 26.3% at 1000 tonnes, up to 89.3% at 10,000 tonnes.

Is underground space energy storage a promising energy storage technology?

In summary, we believe that among the existing energy storage technologies, underground space energy storage has become one of the most promising energy storage technologies in the future because it can achieve large-scale economic and stable storage of energy.

Is a coal mine a suitable place for energy storage?

As a kind of abandoned mine, the coal mine has gradually developed into a more suitable place for energy storage.
