The race to safe energy for AI information facilities has spilled over into some uncommon locations, together with the automotive world.
Battery recycler Redwood Supplies kicked off the pattern final 12 months with a brand new energy-storage division and a challenge that hooked up old EV packs to a Crusoe data center in Nevada. Then Ford mentioned it was repurposing a few of its battery-manufacturing capacity to make grid-scale batteries. And now GM is asserting its personal — arguably extra formidable — plans for an energy-storage system (ESS).
GM unveiled on Tuesday two new phases in its assault on the energy-storage market. The most important swing by far is GM’s new partnership with energy-storage startup Peak Energy. For that partnership, GM is growing a completely new sodium-ion battery chemistry tailor-made for grid-scale deployments.
Outdoors of China, no automaker has introduced plans to construct sodium-ion cells.
“The best way we’re stepping into the market is the simple manner, via ESS,” Kurt Kelty, vp of battery and sustainability at GM, instructed TechCrunch. “The efficiency traits are simply what is required in that market.”
GM wouldn’t share with TechCrunch how a lot cash it’s investing on this energy-storage effort. However we do know the corporate has dedicated $900 million to commercialize new battery chemistries, an funding that features a new battery-development center.
Sodium-ion batteries work equally to lithium-ion, however they swap out key supplies to make the cells cheaper, longer lasting, and fewer liable to overheating. The trade-off is that sodium-ion batteries must be bigger and heavier to retailer the identical quantity of electrical energy.
Peak Vitality has already been engaged on energy-storage methods that use sodium-ion batteries. As a result of sodium-ion batteries behave otherwise from lithium-ion, Peak has developed an energy-storage system with that in thoughts. Its grid-scale batteries don’t have cooling methods or fire-suppression methods as a result of there’s much less threat of overheating. The setup reduces upfront prices, and it also needs to eradicate expensive upkeep, Paul Menson, director of energy-storage commercialization at GM, instructed TechCrunch.
“That is the manifestation of the toughest half to engineer isn’t any half in any respect,” he mentioned. “Remove the half, eradicate the issue.”
GM plans to promote sodium-ions cells to the startup, which is able to then combine them into its merchandise. However that received’t occur instantly.
The primary GM cells are anticipated to enter trial manufacturing on the firm’s Battery Cell Growth Middle in 2028. TechCrunch was just lately given an unique have a look at the brand new facility, which GM expects will lower a few 12 months from the commercialization course of for sodium-ion batteries, lowering prices within the course of.
GM’s sodium-ion cells are nonetheless years away from industrial manufacturing, nevertheless. Within the meantime, the automaker will promote lithium iron phosphate (LFP) cells to LG Vitality Resolution to be used in its energy-storage methods. LG Vitality Resolution already works with GM via its Ultium three way partnership, which makes batteries for the automaker’s EVs.
Alongside the partnerships with LG and Peak, GM introduced that it was increasing its work with Redwood Supplies, the battery-recycling and energy-storage startup based by former Tesla govt J.B. Straubel.
Redwood already buys scrap from GM’s battery factories and used battery packs from its EVs. GM has a pipeline of round 10,000 packs it’s sending to Redwood, and the startup has been working a 12 megawatt/63 megawatt-hour migrogrid utilizing second-life packs at a Crusoe information middle in Sparks, Nevada. GM mentioned it’s shopping for a 7.2 megawatt-hour Redwood system to be used at considered one of its crops in Michigan, which it estimates will reserve it round $3 million over its lifetime.
The GM set up is “a the 1st step” for Redwood, Cal Lankton, chief industrial officer for Redwood, instructed TechCrunch.
Information facilities, the place Redwood already operates, and industrial websites like GM’s are “vastly various things,” he mentioned. The place information facilities may use batteries practically repeatedly to soak up a number of the energy fluctuations from GPUs, industrial websites are extra probably to make use of them to shave off peaks in energy demand, which may decrease month-to-month energy payments, and use them to supply backup energy in case of an outage.
“The manufacturing facility is basically excited as a result of now we’ve bought a extra dependable manufacturing facility,” Kelty mentioned. “Finally, we’ll be having related installations like this in any respect of our factories. It simply makes good financial sense.”
