Are batteries the future of energy storage?

Developments in batteries and other energy storage technology have accelerated to a seemingly head-spinning pace recently — even for the scientists, investors, and business leaders at the forefront of the industry. After all, just two decades ago, batteries were widely believed to be destined for use only in small objects like laptops and watches.

How have batteries changed the energy storage industry?

Batteries continue to lead the charge in energy storage growth, with some fascinating developments shaping their evolution: Battery prices have taken a remarkable journey, dropping by a whopping 97% since 1991. That’s like seeing a $30,000 car from the ’90s now costing just $900!

How much battery storage do we need to meet climate targets?

According to the International Energy Agency, we need to increase global battery storage capacity six-fold by 2030 to meet our climate targets. That’s approximately 1,500 GW of energy storage, with batteries expected to provide about 1,200 GW of that total. Looking further into the future, the picture gets even more ambitious.

Could solid-state batteries transform energy storage as we know it?

Some truly exciting research directions could transform energy storage as we know it. Solid-state batteries replace liquid electrolytes with solid materials, potentially offering higher energy density, faster charging, and improved safety. While manufacturing challenges remain, we expect to see commercial deployment at scale in the late 2020s.

Are EV batteries a good energy source?

Too often, conventional energy sources are called in to smooth out the demand imbalance. Batteries can help store energy for when it’s needed by utility systems — and EV batteries could serve as a readily available and widely distributed source of this storage.

How many GW of battery storage will be installed in 2025?

The pace of deployment is accelerating dramatically. In 2023 alone, global battery storage additions reached 42 GW—more than double the previous year’s installations. Looking ahead, experts predict 80 GW of new additions in 2025, representing an eightfold increase from 2021 levels.
