6 FAQs about [Energy storage capacity issues]

Is excessive energy storage a problem?

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.

Why is energy storage oversupply a problem?

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.

Why do we need energy storage systems?

As the demand for cleaner, renewable energy grows in response to environmental concerns and increasing energy requirements, the integration of intermittent renewable sources necessitates energy storage systems (ESS) for effective utilization.

Is excessive energy storage a threat to China's power system?

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.

Why do we need large-scale energy storage?

With the growing global concern about climate change and the transition to renewable energy sources, there has been a growing need for large-scale energy storage than ever before.

Do we have post-generation energy storage issues?

We have post-generation storage issues as well. Usually, when people think about post-generation energy storage, they think of electrochemical batteries. However, batteries represent a small minority of electrical storage capacity at present. About 90% of current grid storage is in the form of pumped hydro facilities.
