Summary: Nikkei Asia reported on June 27, 2026, and TechCrunch confirmed on July 1, that Honda’s Ohio plant built with LG Energy Solution had begun producing batteries for AI data-center storage rather than EVs. The shift followed Honda’s March termination of three planned United States EV models and about $15.7 billion in recent-fiscal-year write-downs, while the joint venture remained intact. The article frames storage demand—and rivals’ later shipping timelines—as a new outlet for automotive-scale battery manufacturing capacity.
Nikkei Asia broke the news on June 27, 2026: Honda’s U.S. plant had begun turning out batteries intended for AI data centers, and TechCrunch followed with confirmation on July 1. The facility — an Ohio operation run jointly with LG Energy Solution — was originally erected to build electric-vehicle batteries. Today, that same line ships to a different destination: energy storage for data centers. A factory that rose with the EV wave has picked up a fresh customer now that the wave has pulled back — the most unambiguous sign so far that AI’s appetite for electricity is remaking plants designed around the automobile.
The News: Output From an Automotive Line Now Heads to Storage
Timing dealt the Ohio plant a rough hand: it started up right as the EV market went cold. Nikkei reads the switch as a bridge measure — a way to keep the facility running until EV demand finds its way back. Per TechCrunch, the batteries are now rolling off the line, headed for energy storage systems rather than vehicles. One detail stands out: even amid Honda’s sweeping restructuring, the joint venture remains intact, because Honda judged that “batteries are a big business on their own.” Fresh off its first operating loss in years, Honda is treating storage less as a strategic pick than as the cash flow that keeps the line breathing. And for buyers in the storage market, a line engineered to automotive volumes is precisely the capacity they are after.
The Backdrop: Honda’s U.S. EV Program Is Already Finished
Set the clock back three months. March 2026 is when Honda killed its U.S. EV programs, dropping three models that existed only on the drawing board. The stage was set by U.S. federal EV tax credits lapsing in September 2025, which yanked purchases ahead of schedule and left sales shrinking year after year. Across its most recent fiscal year, Honda booked roughly $15.7 billion in write-downs — some tied to the EV overhaul, some to a China business that keeps softening. Capacity sized for hundreds of thousands of electric cars had to land somewhere, and AI data centers arrived at precisely that moment as the market’s hungriest buyer. Nothing about the cells is exotic: they are the same cells this plant was raised to produce, handed to a new class of customer.
The Economics: Why Storage Margins Pull Automakers In
The automakers’ arithmetic here is refreshingly plain. Tesla’s energy arm — Megapack and Powerwall — posts gross margins near 30%, roughly twice what it makes on cars and about three times what a conventional automaker earns. Of the 57 GWh of storage installed across the U.S. last year, Tesla captured 82% on its own. Ford has spun up a storage unit serving data centers and the grid, and GM used June to unveil a sodium-ion chemistry aimed at the same customers — a calculated wager on cheap, plentiful materials and a supply chain China has yet to lock up, though volume shipments wait until later this decade, which hands Honda — already in production — an open runway. Its edge is tempo: rivals are still announcing chemistries while its line moves product. Running factories, proven electrochemistry, drilled manufacturing discipline — stationary storage amounts to a second curve that is ready to go.
The Takeaway for Data Center Power Markets
This year’s first quarter saw U.S. storage deployments hit 9.7 GWh, a 32% jump from a year earlier, and SEIA expects yearly installations to clear 110 GWh by 2030. Over that same window, data center energy demand is forecast to nearly triple. Batteries hold two positions on this playing field: on the grid side, they even out load and make wind and solar output easier to predict; on the data center side, they act as buffer and backup in the interconnection-queue era. Frame it another way: a battery generates nothing — what it shifts is when power gets consumed, and on a grid where every request waits in line, that timing control is valued nearly on par with generation itself. As automakers of Honda’s caliber join the supply side, the storage battery market gains entrants carrying large-scale manufacturing muscle and automotive quality systems. Operators scrambling for batteries should welcome the added supply — yet it equally signals that battery capacity is being reordered from car-oriented to AI-oriented, putting EVs and data centers in direct contention for the very same production lines.
