The Key to Solar and Wind Power Is Battery Storage, and China Is Dominating
Imagine a group of battery banks that together have enough power to keep all of Texas and California going on a peak summer day. That is what China has built in the space of just five years—and it is just getting started.
With the artificial-intelligence boom straining power grids, Beijing is betting on large-scale battery storage banks the size of shipping containers to help manage the load. The technology is particularly valuable in China because the country is heavily investing in solar and wind power, which can’t produce 24-hour-a-day power. Battery storage soaks up excess electricity during sunny and windy days and releases the juice later when it is needed.
