In a twist that’s just as environmentally conscious as it is inventive, used electric vehicle (EV) batteries are finding a second life in the sunny expanses of the California desert. They are being repurposed to store solar power, creating a solution that breathes new life into old batteries while making clean energy more accessible during peak demand hours.
This innovative approach solves two significant issues simultaneously. First, it helps to balance out the availability of clean energy, particularly during the evening hours when demand spikes and solar energy is not being actively produced. Second, it provides a viable recycling solution for EV batteries, which contain precious metals and thus pose a unique challenge in waste management.
B2U Storage Solutions, a visionary company at the forefront of this initiative, has developed a system that capitalizes on the residual capacity of old EV batteries. Even after they’re no longer viable for powering vehicles, these batteries can still hold between 60% to 70% of their original capacity. These “second life” batteries serve as storage devices for solar power, providing a renewable source of energy long after the sun has set.
This second life cycle of the used batteries is not insignificant, lasting approximately five or six years before the batteries need to be recycled. During this period, they act as a buffer for renewable energy, storing power generated during the day for use during peak evening hours.
Furthermore, this recycling and repurposing process is also turning out to be profitable. With cities like Los Angeles pushing hard to meet their renewable energy goals, stored solar energy is increasing in value. In this light, reusing EV batteries becomes an attractive prospect, both financially and environmentally.

Acquiring the old batteries isn’t a challenge for B2U Storage Solutions either. The company sources them from automakers such as Nissan and Honda, acquiring batteries that were replaced under warranty or were in older leased cars.
Even though this is still a fledgling market, the outlook is promising. The number of EVs sold annually is over 2 million, and this figure is only expected to rise. This means that in the future, an increasing number of used batteries will become available for energy storage.
Energy researchers, such as Antoni Tong, see this repurposing of old batteries for energy storage as a better option than current storage technologies, such as hydroelectric power. By comparison, reusing lithium-ion batteries, the power source of EVs emerges as a more cost-effective and environmentally conscious choice. Given the high costs and environmental impact associated with mining the metals used in these batteries, their repurposing makes a lot of sense.
In summary, used EV batteries are proving to be a key player in the race towards more sustainable and efficient energy solutions. By giving these batteries a second life, companies like B2U Storage Solutions are not just saving valuable resources from waste but are also paving the way toward a more sustainable energy landscape.
