Crusoe Is Betting Big on Long-Duration Batteries — And It Could Change AI Infrastructure Forever
Data center companies are racing to secure reliable energy, and Crusoe just made one of the boldest moves yet. The AI-focused data center developer has signed a deal to purchase 12 gigawatt-hours of long-duration battery storage from Form Energy, signaling a major shift in how the industry thinks about power — and who controls it.

Why Long-Duration Battery Storage Is Suddenly Everywhere
For years, battery storage in data centers meant a few minutes of backup power — just enough time to switch to a diesel generator if the lights went out. That era is ending fast.
Long-duration batteries can store energy for 100 hours or more, which means a facility can draw on stored power during peak demand, price spikes, or grid outages. This is not a minor upgrade. It is a fundamental rethinking of how critical infrastructure gets built and sustained. For energy-hungry AI workloads that cannot afford downtime, this kind of storage is becoming non-negotiable.
Crusoe's 12 Gigawatt-Hour Deal With Form Energy Explained
Crusoe confirmed it will purchase 12 gigawatt-hours of Form Energy's iron-air batteries, which are designed to store and discharge electricity over a 100-hour cycle. That is an enormous amount of capacity by any measure, enough to power tens of thousands of homes for several days — or keep a major data center cluster humming through extended grid stress events.
This is only the second large commercial sale Form Energy has publicly announced. The company has been developing its iron-air battery technology for years, with a focus on making long-duration storage economically viable at scale. The Crusoe deal confirms that the technology is ready for serious commercial deployment, not just pilot programs.
Form Energy Already Landed Google — Now It Has Crusoe Too
Just one month before the Crusoe announcement, Form Energy disclosed a deal to build a 30 gigawatt-hour battery installation for a major technology company in Minnesota. That project alone is valued at approximately one billion dollars, a figure that underscores just how seriously large technology buyers are taking long-duration energy storage.
Now, with Crusoe added to its customer roster, Form Energy is establishing itself as the go-to supplier for organizations that need energy independence at a massive scale. Two deals of this magnitude in under two months is not a coincidence. It reflects a market that has shifted from curious to committed.
Redwood Energy Also Enters the Picture
Crusoe did not stop at Form Energy. The company also announced a separate procurement deal with Redwood Energy, broadening its energy storage strategy beyond a single supplier or technology type. While specifics around the Redwood Energy portion of the deal were more limited, the dual-supplier approach signals that Crusoe is building redundancy and flexibility into its energy infrastructure from the ground up.
This kind of diversified sourcing is increasingly common among large-scale infrastructure builders. Depending on a single technology or vendor for something as critical as power creates fragility. Crusoe appears to be engineering resilience into the foundation of its operations.
What This Means for AI Data Center Energy Strategy
The Crusoe deal is not happening in isolation. Across the data center industry, operators are being forced to confront a painful reality: the grid was not built for AI. High-density computing clusters draw staggering amounts of power continuously, and utility infrastructure in many parts of the country is struggling to keep up with demand.
Long-duration battery storage offers a way out of that dependency, or at least a way to reduce it. By storing cheap, off-peak energy and discharging it during peak hours or outages, data centers can reduce their exposure to volatile electricity prices while improving uptime. The economics are compelling, and the operational case is even more so when the workloads running inside are worth millions of dollars per hour.
Crusoe's Broader Mission: Clean, Stranded, and Reliable Energy
Crusoe has always positioned itself differently from traditional data center operators. The company initially built its business around using stranded natural gas — gas that would otherwise be flared at oil wells — to power computing workloads. It was a creative solution to both an environmental problem and an energy access problem.
The shift toward grid-connected facilities backed by long-duration batteries is a natural evolution of that same philosophy. Rather than depending entirely on whatever energy is available, Crusoe is investing in the infrastructure to control and stabilize its own energy environment. This gives the company a competitive edge as energy reliability becomes a core differentiator in the data center market.
The Iron-Air Advantage: Why Form Energy's Technology Stands Out
Form Energy's iron-air batteries work by using a reversible rusting process to store and release electricity. Iron oxidizes when discharging and reduces when charging, using inexpensive, widely available materials. The result is a battery that costs significantly less than lithium-ion alternatives at long durations, making it practical for applications where energy needs to be stored and released over days rather than hours.
This cost advantage is critical for the data center use case. Lithium-ion batteries are well-suited for short-duration storage and fast response, but they become prohibitively expensive when you need to store dozens of gigawatt-hours for extended periods. Iron-air technology fills that gap, and Form Energy appears to have cracked the commercial viability code at exactly the right moment.
A Turning Point for the Energy Storage Industry
Deals like this one are the clearest signal yet that long-duration energy storage has crossed from experimental to essential. When companies like Crusoe are willing to commit to gigawatt-hour-scale battery procurement, it tells the whole market that the technology works, the economics pencil out, and the need is urgent.
Expect more announcements like this in the months ahead. As data center construction continues at a breakneck pace and grid constraints intensify, the companies that secure reliable, long-duration storage capacity now will be the ones that can actually deliver on their expansion promises. Crusoe just moved to the front of that line.
Energy Infrastructure Is the New Competitive Moat
For years, the conversation around data center competitiveness focused on hardware — processors, networking, cooling systems. That conversation has not gone away, but it has been joined by a new one centered on energy. Who controls the power, how reliable it is, and how affordable it stays over time are now central questions for any serious infrastructure builder.
Crusoe's investment in 12 gigawatt-hours of long-duration battery storage is a clear statement that the company sees energy infrastructure as a core strategic asset, not just a utility bill. That mindset, and the capital to back it up, may prove to be one of the most important advantages any data center operator can build in the years ahead.
