ECL has just changed the GAME with the introduction of the world’s first Hydrogen powered off grid green data center with 99.999% uptime. There is massive demand for high-end Data Centers that can meet the demands that come with AI and Machine Learning requirements. What was only a futuristic idea that most thought was 10-20 years out is NOW a reality. Our end-to-end construction platform, modular architecture, is repeatable from 1-2MW’s meeting the needs of even larger data center sites. Imagine the opportunity at hand to build and deliver a Completely Green Power Generation System in this new era of Machine Learning and Artificial Intelligence disruptive technology advancements.

How would you like to be on the ground floor of such a technological revolution. This is your chance to become part of something special as we are poised for hyper growth. ECL was founded by data center veterans from companies including Facebook, Microsoft, LinkedIn, Cisco, HPE and Bloom Energy.

About the Company

ECL

Hydrogen-powered modular data centers for AI

ECL provides Data Center-as-a-Service with hydrogen-powered, modular data centers that are off-grid, using hydrogen fuel cells to generate electricity and water recycled for cooling to create a zero-emission operation. Each 1 MW modular block can be added to scale into larger campuses, enabling deployment in about 6–9 months rather than 18–24 months for traditional facilities. Revenue comes from build-and-handoff or build-and-operate models, serving mid-sized operators up to hyperscale cloud providers. Their goal is to expand a green data center footprint with scalable, high-density AI infrastructure while cutting environmental impact.
