Data center firm ECL has launched a new power solution based on the designs it used for its hydrogen-powered facility in California.

The company this week announced ECL FlexGrid, a new “power‑agnostic platform” designed to allow operators to deploy data center capacity “anywhere.”

FlexGrid reportedly uses ECL’s proprietary power conditioning system to combine multiple sources of energy – including grid power, hydrogen, natural gas, renewables, or diesel – into a single AC or DC power feed.

The company said customers can start with two-10MW of grid power and scale to 20-25MW per site by layering additional energy sources within a short period of time. The platform’s flexible design means adding natural gas turbines, hydrogen systems, or other prime movers does not require re‑designing the data center.

“The money, the growth, and the real infrastructure challenges in AI are rapidly expanding from training to inferencing, and creating strong value and opportunity as a result,” said Yuval Bachar, founder and CEO of ECL. “Inference has to live close to people, data, and applications, in and around major cities, smaller metros, and industrial hubs where there is rarely a spare 50 or 100 megawatts sitting on the grid, and almost never a mature hydrogen ecosystem. FlexGrid was built exactly for the market conditions we face today. We take whatever energy source is available locally, normalize it through our power conditioning system, and deliver clean, reliable power to AI data centers at the Edge.”​

ECL launched its first modular hydrogen data center back in May 2025, with a small deployment at its site in Mountain View, California. AI cloud firm Lambda has deployed an Nvidia cluster at the facility.

The company has previously said that each of its data center modules supports 1MW and can cool up to 150kW per rack.

Launched in 2023, ECL is backed by Molex Ventures and Hyperwise Ventures. The company is also targeting a 1GW hydrogen-powered AI data center in Texas, with Lambda as its first tenant.

“Hydrogen was an important starting point for ECL, but it was never the end state,” added Bachar. “We built our patents and architecture around the idea that power should be flexible. You should be able to plug in hydrogen where it’s abundant, natural gas where it’s ubiquitous, renewables where they are competitive, and still deliver the same high‑quality power to the data hall. FlexGrid is how we take that vision to market and put ECL at the center of the AI inferencing tornado.”​
