Are pumped storage power plants a problem in China?

To address the problem of unstable large-scale supply of China's renewable energy, the proposal and accelerated growth of new power systems has promoted the construction and development of pumped storage power plants (PSPPs), and the site selection of conventional PSPPs poses a challenge that needs to be addressed urgently.

Can abandoned mines be turned into energy storage?

Turning abandoned mines into energy storage is one example of many solutions that exist around us, and we only need to change the way we deploy them,” concludes Behnam Zakeri, study coauthor and a researcher in the IIASA Energy, Climate, and Environment Program.

Can pumped storage technology be used in abandoned coal mines?

This article summarizes the pumped storage technology and its application and comprehensively analyzes the advantages of the PSPP in abandoned mines from the views of China's renewable energy growing trends, national policies, and underground space distributions in coal mines.

Can old coal plant sites be converted to new storage and renewable projects?

Conversion of old coal plant sites to new storage and renewable projects is happening in New Jersey, Nevada, Louisiana, and elsewhere across the country.

Is energy storage the future of China's power system?

Otherwise, the excess renewable energy power will be abandoned, while the industrial and residential demand for electricity does not decrease. Given the development of energy structure and the trend of shifting to renewable energy, energy storage is a main participant in the future of the power system in China .

Are underground pumped storage power plants a viable solution?

Therefore, Underground Pumped Storage Power Plants (UPSP), as first introduced in the early 20th century by Fessenden [ 11 ], offer a viable solution that capitalizes on the utilization of abandoned underground spaces and effectively circumvents topographical constraints and limitations associated with surface footprint [ 5, 12 ].
