Spyros Foteinis highlights the acknowledged problem that an insufficient capacity to store energy can result in generated renewable energy being wasted (Nature 632, 29; 2024). But the risks for power-system security of the converse problem — excessive energy storage — have been mostly overlooked.
The expansion is driven mainly by local governments and lacks coordination with new energy stations and the power grid. In some regions, a considerable storage oversupply could lead to conflicts in power-dispatch strategies across timescales and jurisdictions, increasing the risk of system instability and large-scale blackouts.
But the risks for power-system security of the converse problem — excessive energy storage — have been mostly overlooked. China plans to install up to 180 million kilowatts of pumped-storage hydropower capacity by 2030. This is around 3.5 times the current capacity, and equivalent to 8 power plants the size of China’s Three Gorges Dam.
Energy storage is used to facilitate the integration of renewable energy in buildings and to provide a variable load for the consumer. TESS is a reasonably commonly used for buildings and communities to when connected with the heating and cooling systems.
Various application domains are considered. Energy storage is one of the hot points of research in electrical power engineering as it is essential in power systems. It can improve power system stability, shorten energy generation environmental influence, enhance system efficiency, and also raise renewable energy source penetrations.
The complexity of the review is based on the analysis of 250+ Information resources. Various types of energy storage systems are included in the review. Technical solutions are associated with process challenges, such as the integration of energy storage systems. Various application domains are considered.

Net-zero power: Long-duration energy storage for a renewable grid
We estimate that by 2040, LDES deployment could result in the avoidance of 1.5 to 2.3 gigatons of CO 2 equivalent per year, or around 10 to 15 percent of today''s power sector emissions. In the United States alone, LDES could reduce the overall cost of achieving a fully decarbonized power system by around $35 billion annually by 2040.
