As the race to deliver AI infrastructure at scale intensifies, the greatest challenge isn’t rack density or cooling, it’s access to data center power.

According to Bloom Energy's Mid-Year Data Center Power Report, in Virginia’s data center alley, 25 percent of all electricity already flows to data centers. Nationally, that number is expected to rise from four percent in 2023 to 12 percent by 2028.

Grid access is lagging behind demand, delaying new data center campus builds and forcing operators to rethink how they fuel growth and scale. In this high-stakes environment, onsite power generation driven by fuel cell technology has emerged as a viable solution.

“Fundamentally, the report confirms that developers recognize that onsite power has emerged as a necessity for those who want to compete in the AI race,” says Aman Joshi, chief commercial officer at Bloom Energy.

Fuel cell technology is stepping up to fill the power gap. Fuel cell onsite power systems are clean, scalable, and fast to deploy, offering operators a path to energy resilience without the long wait times or volatility of utility supply.

The core of the data center power solution: Fuel cell technology

Bloom’s Energy Server fuel cell system is built on solid oxide fuel cell (SOFC) technology. It generates electricity through an electrochemical reaction, without combustion. Taking advantage of its modular design, it can be configured to produce power at five nines (99.999 percent) reliability with minimal overbuild.

Just as important as the tech is the deployment model. Bloom works with customers across the lifecycle, from permitting and design to fuel sourcing and maintenance. This holistic approach is enabling developers to overcome the regulatory friction that often slows down or derails onsite generation projects.

Bloom’s streamlined permitting approach and skid mounted design help to shorten lead times significantly. In fact, data center power can be delivered in as little as 90 days. “Our systems can be installed in a matter of months,” explains Joshi. “That means we can help operators meet urgent power needs without waiting years for grid upgrades.”

Additionally, these systems emit nearly zero criteria air pollutants – the six most widespread and harmful air pollutants that are regulated under the National Ambient Air Quality Standards (NAAQS) in the US. This helps streamline the process further, reducing a project’s environmental impact, thereby increasing the likelihood that permitting agencies will give it the go-ahead.

Meeting AI’s power profile

AI workloads don’t just use more power, they also use it differently. They’re dense, fluctuating, and less predictable. That’s why fast, dispatchable, and resilient data center power is becoming a key enabler of AI-ready infrastructure.

As fuel cells have minimal moving parts and directly produce power through an electrochemical process, they are well suited for handling these dynamic power fluctuations.

“Fuel cells are ideally suited to the complexities of AI workloads,” says Joshi. “They deliver the speed, scale, and reliability that data centers need, without compromising sustainability.”

Addressing local challenges

While the advantages are clear, data center development still comes with real-world challenges. Regional regulations vary widely, and public concerns about local environmental impacts can trigger opposition, slowing progress further.

Each jurisdiction has its own requirements, and data center power projects often face resistance tied to permitting, infrastructure access, or land use. “We’ve built our services around helping operators navigate these issues and accelerate deployments,” says Joshi.

“We’re working with policymakers across the spectrum, and we’re designing for the future. While natural gas is the primary fuel today, our systems are ready for hydrogen, biogas, or other alternatives as they become viable.”

Real-world momentum: Fuel cells in action

Fuel cells are already being deployed at scale by hyperscalers, data centers, and developers. Take Oracle Cloud for example. Having faced grid delays, they partnered with Bloom to power entire AI data centers using fuel cells in under 90 days. That’s not just fast. It’s strategic.

CoreWeave, the AI hyperscaler, selected Bloom’s fuel cells for its Chicago high-performance data center project, allowing them to energize GPU-intensive workloads while avoiding multi-year utility delays.

Equinix has also expanded its long-standing partnership with Bloom, which now exceeds 100MW of power capacity.

For data center operators racing to lead in the AI era, fuel cells are no longer just an alternative source of power – they’re quickly becoming the standard.

Looking forward

The path to powering tomorrow’s data centers requires solutions that can deliver at the speed and scale of AI. AI adoption is moving too fast for the grid to keep pace. At the same time, environmental targets and regulatory complexity are adding pressure.

What is clear, however, is that the grid alone won’t be enough. Onsite generation, especially flexible, clean, and reliable solutions like fuel cells, will be essential to closing the power gap.
