Tesla EV Battery Packs Reused for Energy Storage Systems in Finland and California

Two companies have announced plans to create a clean energy storage using old batteries from Tesla’s vehicles.

Energy storage firms Cactos and Smartville announced $10 million in fundraising to help commercialize systems using repurposed batteries from Tesla’s electric vehicles (EVs), as detailed in a report from EnergyStorage.news on Wednesday.

San Diego-based Smartville has an energy storage system (ESS) dubbed “MOAB,” which features 250kW/500kWh of power and uses a combination of repurposed Tesla batteries and those from the electric Nissan Leaf.

Smartville recently received a $6 million grant from the U.S. Department of Energy’s $74 million domestic battery recycling fund, set to help the firm reuse Tesla’s battery packs for energy storage. The company forecasts deploying 50-100MWh of energy storage in 2024.

“We believe focusing on battery packs rather than disassembly and modules allows us to scale,” Smartville President Mike Ferry said. “For this market to reach the MWh and even GWh projects it does not make sense from a labour or financial perspective to disassemble.”

Additionally, Finland-based Cactos raised €2.5 million ($3 million USD) to help commercialize its 100kWh energy storage system, which also uses repurposed Tesla batteries. Cactos says it gets Tesla batteries from a recycling company in Norway that breaks them down into modules and aims to ship 100 units (10MWh) of energy storage through April 2024.

Both firms receive their Tesla batteries from third-party salvage companies and plan to begin shipping their ESS products in 2024.

A similar ESS program in Australia uses old Nissan Leaf batteries and was announced by the automaker in September.
