2025 electric vehicle energy storage

How big is the EV battery market?

Today, the market for batteries aimed at stationary grid storage is small—about one-tenth the size of the market for EV batteries, according to Yayoi Sekine, head of energy storage at energy research firm BloombergNEF.

Can EV batteries supply short-term storage facilities?

For higher vehicle utilisation, neglecting battery pack thermal management in the degradation model will generally result in worse battery lifetimes, leading to a conservative estimate of electric vehicle lifetime. As such our modelling suggests a conservative lower bound of the potential for EV batteries to supply short-term storage facilities.

Are electric vehicles a good option for the energy transition?

Our estimates are generally conservative and offer a lower bound of future opportunities. Renewable energy and electric vehicles will be required for the energy transition, but the global electric vehicle battery capacity available for grid storage is not constrained.

Will EV & stationary batteries continue to grow?

Looking forward, investors and carmakers have been fleshing out ambitious plans for manufacturing expansion, confident that demand for EV and stationary batteries will continue to grow as a result of increasing electrification and power grid decarbonisation.

How much electricity does the EV fleet use in 2023?

In 2023, the global EV fleet consumed about 130 TWh of electricity – roughly the same as Norway’s total electricity demand in the same year. Zooming out to the global scale, EVs accounted for about 0.5% of the world’s total final electricity consumption in 2023, and around 1% in China and Europe.

Should EV batteries be used as stationary storage?

Low participation rates of 12%–43% are needed to provide short-term grid storage demand globally. Participation rates fall below 10% if half of EV batteries at end-of-vehicle-life are used as stationary storage. Short-term grid storage demand could be met as early as 2030 across most regions.
