STACK Infrastructure has piloted the first use of electrochemical low‑carbon cement in data center construction, partnering with Sublime Systems at its Prince William County, Virginia campus. The project involved a test pour of Sublime Cement, a material produced through an electrochemical process that avoids the carbon emissions of traditional cement. The pilot focused on a loading dock—an area subject to high wear—to evaluate the material’s long‑term durability. Early testing showed compressive strength above standard performance levels.
The move comes as AI‑driven demand accelerates new data center construction, raising concerns about the industry’s carbon footprint. STACK is positioning sustainable materials as part of its broader Net Zero strategy, which also includes supplementary cementitious material (SCM) replacements and mineralized carbon dioxide solutions. Prince William County officials called the pilot an example of how private‑sector partnerships can tackle real sustainability challenges.
Sublime Systems, a Boston‑based startup, sees the pilot as validation that its electrochemically produced cement can scale into critical infrastructure. STACK said the project demonstrates leadership in reducing embodied carbon across its developments and sets a precedent for wider adoption of sustainable materials in the data center sector.
- STACK and Sublime piloted the first electrochemical low‑carbon cement pour in the data center industry
- Pilot project located at STACK’s Prince William County, Virginia campus
- Sublime Cement performance exceeded compressive strength expectations
- Cement was deployed in a high‑traffic loading dock to test durability
- Initiative supports STACK’s Net Zero strategy alongside other embodied carbon reduction efforts
“With STACK among the most innovative and forward‑thinking data center developers, the piloting of carbon‑avoiding Sublime Cement is a powerful validation of our technology in the infrastructure that is essential for enabling the digital economy,” said Dr. Leah Ellis, CEO and Co‑founder of Sublime Systems.
🌐 Why it Matters: Data centers are projected to drive significant emissions growth unless new construction practices reduce embodied carbon. This pilot highlights how low‑carbon building materials can play a central role in aligning digital infrastructure expansion with climate goals.
