As the global transition toward renewable energy accelerates, storing electricity generated by intermittent sources, such as solar and wind, becomes more urgent. Power production often plunges when the sun sets or the wind dies down. At the same time, demand can surge unexpectedly, placing strain on electric grids that are already juggling the stresses of an electrified future.
Enter gravity batteries, a technology that uses one of the simplest forces in nature—gravity—to store large amounts of energy. This approach, now being trialed in various forms worldwide, promises to offer a cleaner, more durable, and geopolitically flexible alternative to lithium-ion batteries. Here’s what you need to know about the technology, its viability, and some pioneering projects seeking to prove it on a grand scale.
The urgent need for massive energy storage
Renewable energy sources like solar and wind can supply huge amounts of…
