Behind the scenes of Equinix’s nuclear and fuel cell bet

Inside the world’s fastest-growing digital infrastructure company, executives are quietly rewriting the playbook on how data centers are powered.

The trigger is clear: artificial intelligence is accelerating global electricity demand, and grids are already struggling to keep up.

According to the International Energy Agency, consumption is set to climb 4% annually through 2027, marking the sharpest rise in years.

For Equinix, that forecast is not just a statistic, but a warning sign that traditional energy sources will not be enough.

The company began scouting unconventional partners, from nuclear startups to fuel cell pioneers, to safeguard its future growth.

Oklo was the first to sign on, offering 500MW from small modular reactors designed to run on recycled nuclear waste.

Radiant followed with a deal to supply 20 portable Kaleidos microreactors that can be delivered and activated in days.

In the Netherlands, Equinix aligned with ULC-Energy and Rolls-Royce SMR for as much as 250 MWe of next-generation nuclear capacity.

Across Europe, Stellaria secured a 500 MWe agreement with a molten salt reactor that creates its own fuel while recycling waste.

Meanwhile, Bloom Energy deepened its decade-long relationship with Equinix, expanding solid-oxide fuel cells to more than 100MW across U.S. facilities.

Those fuel cells already helped the company avoid 285,000 metric tons of emissions and conserve 382 billion gallons of embedded water.

Behind the curtain, Equinix is also bankrolling transmission upgrades, new substations, and emergency systems to reinforce utilities.

Executives say the goal is not only to power data centers, but also to strengthen the communities and grids they rely on.

Equinix has already achieved 96% renewable energy coverage globally and is pressing toward 100% by 2030.

Cooling systems, efficiency standards, and liquid-based technologies are also being rolled out to maximize the energy it does secure.

Behind the headlines, the story is simple: Equinix is betting that nuclear reactors and fuel cells will quietly become the backbone of the AI era.
