Equinix’s 2025 Fuel Cell Strategy: Powering AI with Over 100 MW of On-Site Energy

Industry Adoption: How Equinix is Scaling Fuel Cell Deployments for the AI Era

Equinix’s adoption of fuel cell technology has undergone a significant strategic evolution, transitioning from targeted validation to aggressive, large-scale commercial deployment. Between 2021 and 2024, the company’s approach was characterized by a “strategic pivot” toward grid-independent power. This period focused on proving the technology’s viability for primary power generation, exemplified by the $142 million investment in the SV11 data center in Silicon Valley, which planned for a 20 MW Bloom Energy fuel cell installation. Alongside this, Equinix established a global R&D footprint to de-risk future technologies, launching its Co-Innovation Facility (CIF) in the U.S. to test next-generation systems, participating in the €2.5 million E2P2 consortium in Europe to develop high-efficiency solid-oxide fuel cells (SOFCs), and partnering with the National University of Singapore (NUS) to research hydrogen-based solutions. This phase was about building a foundation, growing installed capacity from 43.5 MW to over 72 MW, and validating fuel cells as a reliable alternative to traditional grid power.

Beginning in 2025, Equinix’s strategy entered a new phase of accelerated scaling, driven by the explosive energy demands of AI and high-performance computing. The inflection point was the significant expansion of its partnership with Bloom Energy, with total contracted capacity surpassing 100 MW across more than 19 U.S. data centers. This move signals that fuel cells are no longer just an alternative but a core component of Equinix’s power strategy for ensuring operational resilience and capacity for AI workloads. By April 2025, the company reported a global deployment of 72 MW with a total of 104 MW contracted, underscoring a robust execution pipeline. This commercial ramp-up is part of a newly diversified energy portfolio announced in August 2025, which pairs on-site fuel cells with future-looking agreements for next-generation nuclear power. This dual-track approach mitigates immediate grid constraints with a proven, scalable technology while planning for long-term, zero-carbon baseload power, creating a new opportunity to market highly resilient, AI-ready infrastructure.

Geography: Mapping Equinix’s Global Fuel Cell Strategy

Between 2021 and 2024, Equinix’s fuel cell activities were geographically diversified, reflecting a strategy of testing and validation in its key global markets. The United States served as the primary commercial testing ground, with the $142 million SV11 project in Silicon Valley and the Co-Innovation Facility in Ashburn, Virginia, demonstrating a focus on power-constrained, high-demand regions. Simultaneously, Europe became the hub for advanced R&D through the E2P2 consortium, which involved partners across the continent and a proof-of-concept deployment in Milan, Italy. In the Asia-Pacific region, the partnership with NUS in Singapore established a research foothold to tackle the unique challenges of deploying hydrogen technologies in tropical climates. This distributed approach allowed Equinix to build regional expertise and de-risk technology in varied operational environments.

From 2025 onwards, the geographic focus has dramatically sharpened. While R&D efforts continue globally, the large-scale commercial deployment of fuel cells is overwhelmingly concentrated in the United States. The expanded agreement with Bloom Energy targets more than 19 data centers across six U.S. states, confirming the U.S. as the lead market for scaling this technology. This concentration is likely driven by a combination of surging AI-related energy demand, grid reliability concerns, and a mature partner ecosystem. While Equinix continues to invest in other regions, such as the opening of an AI-ready data center in Chennai, India, and raising SGD-denominated green bonds in Singapore, the physical deployment of fuel cell megawatts is currently a U.S.-centric story. This presents a risk of geographic dependency but also signals where the business case for fuel cells is most compelling today.

Technology Maturity: From Validation to Scalable Deployment for Equinix

In the 2021–2024 period, Equinix’s fuel cell strategy was focused on moving technology across the maturity spectrum. Natural gas-powered Solid-Oxide Fuel Cells (SOFCs) were already in a commercial, but still scaling, phase, with deployments growing from 43.5 MW to over 72 MW. The key validation point was elevating their role from backup to primary power at the SV11 facility. In parallel, the Co-Innovation Facility moved concepts like “generator-less” data centers into a pilot and validation phase. At the earliest R&D and demonstration stage, Equinix was engaged in two critical projects: the E2P2 consortium in Europe, which successfully demonstrated a high-efficiency (60%) SOFC system, and the NUS partnership in Singapore, which initiated fundamental research into the viability of hydrogen-based PEM fuel cells for data centers.

In 2025, the maturity of SOFC technology for data center applications has been decisively confirmed. The technology is now in a large-scale commercial deployment phase, evidenced by the landmark agreement to surpass 100 MW of capacity with Bloom Energy. This is no longer a test; it is a core infrastructure strategy. A crucial advancement is the validation of these deployed systems as “hydrogen-ready,” capable of accepting a blend of up to 50% hydrogen. This is a critical pre-commercial feature that future-proofs the investment and provides a clear transition path from natural gas. While SOFCs scale, Equinix is simultaneously initiating early-stage exploration into next-generation nuclear with partners like Oklo and Radiant. This shows a sophisticated, multi-horizon technology strategy: scaling what works today (SOFCs), preparing for the transition tomorrow (hydrogen-readiness), and exploring what comes next (next-gen nuclear).

Forward-Looking Insights: What to Expect from Equinix’s Energy Strategy

The data from 2025 provides clear signals about the trajectory of Equinix’s energy strategy. The company has successfully moved fuel cells from the innovation lab to the core of its U.S. power infrastructure, establishing a replicable model for supporting AI-driven growth. For the year ahead, market actors should focus on three key validation points. First is execution on contracted capacity; successfully commissioning the remaining 30+ MW of fuel cells will demonstrate the scalability of the deployment model. Second, the “hydrogen-ready” claim must be put to the test. Watch for the announcement of the first pilot project to blend hydrogen into the fuel stream at a live data center, which will be the next major step in the company’s decarbonization journey.
