GM is trying to turn more of its battery work toward energy storage, a market being pulled in several directions at once by data centers, industrial power needs and the electric grid.
The automaker has described a broader energy-storage strategy built around several pieces: a sodium-ion battery effort with Peak Energy, lithium iron phosphate cell supply for LG Energy Solution, and an expanded relationship with Redwood Materials. Some of the operational details reported around those plans have not been independently verified, so the useful reading is less that GM has a finished product in market and more that it is placing several bets on where large stationary batteries may be needed next.
The timing is not hard to understand. AI data centers are putting new pressure on power infrastructure, while factories and utilities are looking for batteries that can smooth demand spikes, provide backup power and reduce exposure to high electricity costs. That does not make every battery chemistry or deployment model a sure thing, but it explains why an automaker with battery factories and cell-development work would look beyond vehicles.
GM’s Sodium-Ion Bet Is Aimed at Stationary Storage
The most forward-looking part of GM’s plan centers on sodium-ion batteries. In the arrangement described by the company, GM would develop sodium-ion cells for grid-scale use and supply them to Peak Energy, which would integrate them into energy-storage systems.
Sodium-ion batteries are often discussed as a lower-cost alternative to lithium-ion batteries because they rely on different raw materials. They also come with trade-offs. Compared with lithium-ion cells, sodium-ion batteries are generally expected to have lower energy density, which means a system may need more space or weight to store the same amount of energy. That matters far less for a fixed installation beside a factory, substation or data center than it would inside a passenger vehicle.
That is why stationary storage is a plausible first market. A data center or industrial site does not need a battery pack to fit under a vehicle floor or deliver long driving range. It needs predictable output, manageable cost, long life and safe operation over repeated use.
Peak Energy has been developing sodium-ion energy-storage systems, and the source report says its design is meant to account for the chemistry’s different behavior. The report also says Peak’s grid-scale systems avoid some cooling and fire-suppression equipment because of lower overheating risk. Because that specific system architecture has not been independently verified here, it should be treated as a company-claimed design advantage rather than a settled market standard.
The Timeline Still Points to a Long Commercial Ramp
GM’s sodium-ion cells are not being presented as an immediate commercial product. The first trial production is expected in 2028 at GM’s Battery Cell Development Center, according to the source report, but firm commercial timing remains less clear.
That matters for utilities, data-center operators and industrial buyers. Stationary storage projects are usually planned around real interconnection queues, power contracts, facility loads and financing assumptions. A chemistry that may lower cost in the future is relevant, but it does not solve a near-term power constraint until it is available at scale and backed by field data.
GM has also been investing in battery development more broadly. The source report says the automaker has committed $900 million to commercialize new battery chemistries, including work tied to a battery-development center. Since GM did not share a specific investment figure for the energy-storage push itself, that broader commitment should not be read as a direct budget for one storage program.
In practical terms, the sodium-ion effort appears to be a medium-term manufacturing and chemistry bet. It gives GM a way to use battery expertise in a market where size and weight are less punishing than in vehicles. It also gives Peak Energy a potential domestic cell partner if the development path works.
LFP Cells Fill the Nearer-Term Gap
While sodium-ion remains a future-facing effort, GM is also tied to a nearer-term lithium iron phosphate route. The source report says GM will sell LFP cells to LG Energy Solution for use in energy-storage systems. A firm deployment timeline was not publicly confirmed in the provided material.
LFP chemistry is already common in stationary storage because it is generally valued for cost, durability and thermal behavior. For GM, selling cells into energy storage could provide another outlet for battery-manufacturing capacity as the EV market continues to move unevenly across segments and regions.
LG Energy Solution is already connected to GM through the Ultium joint venture, which makes batteries for GM electric vehicles, according to the source material. That existing relationship may make the energy-storage supply path easier to coordinate, though the specific commercial terms were not disclosed.
The distinction between LFP and sodium-ion is important. LFP is the more immediate, established chemistry for storage products. Sodium-ion is the longer bet that could become attractive if it reaches the right combination of cost, lifespan, safety and manufacturability.
Redwood Adds a Second-Life Battery Angle
GM’s storage plans also include Redwood Materials, the battery-recycling company founded by former Tesla executive J.B. Straubel. Redwood already works with GM on battery scrap and used battery packs, according to the source report.
The reported expansion includes GM purchasing a 7.2 megawatt-hour Redwood energy-storage system for one of its Michigan plants, with GM estimating about $3 million in lifetime savings. Because the specific savings estimate and installation details have not been independently verified here, they are best treated as GM’s projection rather than a guaranteed result.
The Redwood piece is different from the sodium-ion and LFP supply efforts. Instead of building new cells for stationary systems, Redwood’s model can use second-life EV packs where their remaining capacity is still useful for fixed storage. That can be attractive for facilities that need backup power or peak-shaving but do not require the same performance profile as a new EV battery.
The source report also says Redwood has been operating a 12 megawatt, 63 megawatt-hour microgrid using second-life packs at a Crusoe data center in Sparks, Nevada, and that GM has a pipeline of around 10,000 packs going to Redwood. Those figures have not been independently verified here, but they show the kind of scale being discussed around second-life battery systems.
Why Data Centers and Factories Need Different Storage
The same battery system does not always serve the same purpose. Data centers may use batteries to manage fast changes in power demand and maintain continuity for high-value computing workloads. Industrial sites are often more focused on lowering demand charges, shaving peak usage and keeping critical operations running during outages.
That difference helps explain why GM is not pointing to a single storage path. New LFP cells, future sodium-ion cells and second-life EV packs could all serve stationary markets, but not necessarily the same customers or duty cycles.
For data centers, the biggest question is whether batteries can help manage power reliability and grid constraints at the scale AI infrastructure requires. For factories, the economics are often more local: electricity rates, outage risk, peak demand fees and the value of avoided downtime.
GM’s own plants may become early proof points if the Redwood installation performs as expected. Still, one factory system would not prove the full business case across data centers, utilities and industrial customers. It would mainly give GM a way to test storage economics inside its own operations before arguing for broader deployment.
The Bigger Picture
GM’s move into energy storage is less of a side project than it may appear. Automakers have spent years building battery supply chains, cell partnerships and manufacturing expertise for EVs. Stationary storage gives that infrastructure another possible market, especially as electricity demand rises and grid operators look for flexible capacity.
The risk is execution. Sodium-ion must move from development to trial production and then to bankable commercial systems. LFP cell supply has to compete in a market with established storage manufacturers. Second-life systems have to prove that used EV packs can deliver predictable performance, safety and savings across real industrial settings.
For buyers and grid planners, the immediate takeaway is measured interest rather than certainty. GM is signaling that its battery strategy extends beyond cars, with data centers and factories among the target use cases. The hard part will be turning that signal into systems that are available, affordable and proven in the field.
