From cars to data centres, GM pushes into energy storage with three new battery deals
π GM is expanding its energy storage business beyond electric vehicles with three new strategic partnerships.
β‘ The company announced a sodium-ion battery development deal with Peak Energy, targeting trial production by 2028.
π This partnership makes GM the first Western automaker to commit to large-scale sodium-ion manufacturing trials outside of China.
π Sodium-ion batteries use cheaper materials like iron and manganese, reducing reliance on supply chains concentrated in China.
π While sodium-ion cells are too heavy for EVs due to lower energy density, they are ideal for stationary grid storage where weight is not a factor.
π€ GM will also supply lithium iron phosphate (LFP) battery cells to LG Energy Solution for integration into data centre and utility storage systems.
β»οΈ A third deal involves purchasing a 7.2 MWh battery energy storage system from Redwood Materials for its Milford Proving Ground.
π Redwood's system utilizes second-life EV batteries that no longer meet automotive performance standards but remain suitable for stationary use.
π° GM aims to monetize its $900 million investment in battery chemistry by creating a new revenue stream beyond vehicle sales.
π The Battery Cell Development Center in Warren, Michigan, was originally built for EV development but will now support energy storage projects.
β οΈ GM faces risks as it lacks a track record in energy storage and competes against established players like Tesla Energy and BYD.
π¬ Sodium-ion technology remains unproven at commercial scale outside China regarding long-term cycle life and degradation characteristics.
π GM possesses significant manufacturing infrastructure and purchasing power to potentially overcome these execution challenges.
π Slowing EV sales growth has prompted automakers to seek new markets for their battery manufacturing capacity.
π The strategy relies on sodium-ion cells meeting cost and performance targets by the time real-world data is generated from current projects.
- GM announced a sodium-ion battery development partnership with Peak Energy, marking it as the first Western car company to move beyond research papers into manufacturing trials for this technology.
- The collaboration aims to reach trial production by 2028 at GM's Battery Cell Development Center in Warren, Michigan, leveraging Peak Energy's chemistry and GM's manufacturing expertise.
- GM secured a lithium iron phosphate supply deal with LG Energy Solution to fill the gap until sodium-ion cells are ready, supplying cells for energy storage systems serving data centres and utility customers.
- GM is purchasing a 7.2 MWh battery energy storage system from Redwood Materials to be installed at its Milford Proving Ground in Michigan for backup power and peak demand management.
- The strategy allows GM to monetize its $900 million investment in battery chemistry by adding stationary storage as a second revenue stream, spreading costs across a larger market.
- Redwood Materials' system utilizes second-life EV batteries, contributing to the largest second-life battery deployment in North America with an existing 12 MW, 63 MWh microgrid at a Crusoe data centre.
- GM has no track record in energy storage, facing competition from established players like Tesla Energy, Fluence, and BYD that have years of deployment experience and existing customer relationships.
- Sodium-ion technology is unproven at commercial scale outside China, with CATL and BYD having shipped cells but not yet demonstrated the cycle life and degradation characteristics required for utility customers over 15 to 20-year project lifetimes.
