Bad news about energy storage

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.

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.

Should we rely on renewables for massive amounts of storage?

If we plan to rely on them for massive amounts of storage as more renewables come online—rather than turning to a broader mix of low-carbon sources like nuclear and natural gas with carbon capture technology—we could be headed down a dangerously unaffordable path. Small doses

What's new in energy storage in the second quarter?

In the second quarter, all new storage projects involved batteries. The largest project, with a capacity of 350 megawatts, was the third phase of Moss Landing Energy Storage in California, which went online in June.
