Equinix's Bold Move into Nuclear Energy: A Sustainable Future for Data Centers

The Importance of Sustainable Energy Solutions

The challenges of powering the planet's ever-increasing fleet of data centres are significant. Virtified has followed these developments for years. Recently, Equinix made headlines with its commitment to nuclear energy. This isn't the first announcement of its kind; for instance, Microsoft has also taken steps in this direction. However, Equinix's actions are noteworthy. The company has a long and demonstrated track record of taking environmental sustainability seriously.

Nuclear energy is a hot topic, especially considering its prominence in the 2025 federal election in Virtified's home country.

Virtified considers Equinix's move into nuclear as a (seemingly) necessary sign of things to come.

Equinix's Partnerships and Innovations

Equinix's strategy involves collaborating with several innovative companies to harness the power of nuclear energy. Here are some key partnerships:

Oklo: Pioneering Small Modular Reactors

In 2024, Equinix became the first data center operator to sign an agreement with a small modular reactor (SMR) company. This agreement allows Equinix to procure 500MW of energy from Oklo’s next-generation fission Aurora powerhouses. Oklo's fast reactors come with inherent safety features and can be fueled by nuclear waste. This innovative approach not only addresses energy needs but also contributes to waste management.

Radiant: Microreactor Technology

Equinix has also announced a preorder agreement for 20 of Radiant’s Kaleidos microreactors. These microreactors provide a reliable, long-lasting energy source. They can be transported anywhere, installed in days, and deployed safely alongside existing equipment. This flexibility is crucial for meeting the energy demands of modern data centers.

ULC-Energy and Rolls-Royce SMR

Equinix signed a Letter of Intent with ULC-Energy for a Power Purchase Agreement (PPA) of up to 250 MWe to power data centers in the Netherlands. ULC-Energy, based in Amsterdam, has selected Rolls-Royce SMR as its preferred technology solution. Rolls-Royce SMR is developing a 470 MWe light water small modular reactor. This partnership is a significant step towards sustainable energy solutions in Europe.

Stellaria: The Future of Molten Salt Reactors

Equinix has also secured a pre-order power agreement for 500 MWe to expand data centers across Europe. Stellaria, incubated by Schneider Electric and the CEA (French Atomic Energy Agency), is developing the world's first molten salt Breed & Burn reactor. This reactor will breed 100% of its liquid fissile fuel inside the reactor without the need for refueling. It also recycles spent fuels and burns long-life waste, making it an environmentally friendly option.

Advanced Fuel Cells: A Complementary Technology

In addition to nuclear energy, Equinix has been exploring advanced fuel cells for scalable, efficient, and cleaner onsite energy. The company has been using fuel cells for over ten years in collaboration with various partners.

Bloom Energy: Expanding Fuel Cell Deployment

Equinix has an agreement to expand its deployment of solid-oxide fuel cells to over 100MW across 19 data centers in six states. This onsite power generation is highly efficient and enables Equinix to avoid 285,000 MTCO2e emissions and 382 billion gallons of embedded water use. This commitment to reducing carbon emissions aligns with global sustainability goals.

The Future of Energy in Data Centers

Equinix's move into nuclear energy and its partnerships with innovative companies demonstrate a commitment to sustainable energy solutions. As the demand for data centers continues to grow, finding reliable and environmentally friendly energy sources is crucial.

Embracing Innovation for a Sustainable Future

The integration of nuclear energy and advanced fuel cells represents a significant shift in how data centers can operate. These technologies not only provide reliable energy but also contribute to reducing the environmental impact of data centers.

Equinix's proactive approach sets a precedent for the industry. By embracing innovative energy solutions, the company is paving the way for a more sustainable future.

Conclusion

Equinix's commitment to nuclear energy and advanced fuel cells showcases its dedication to sustainability. As the world moves towards cleaner energy solutions, Equinix is leading the charge. The company's partnerships with Oklo, Radiant, ULC-Energy, and Stellaria highlight the importance of collaboration in achieving these goals.

The future of energy in data centers is bright, and Equinix is at the forefront of this transformation. The shift towards sustainable energy is not just a trend; it's a necessity for the planet's future.
