Stack Infrastructure has completed a pilot project using Sublime Cement, developed by Sublime Systems, at its Prince William County, Virginia data center campus. According to Stack Infrastructure, this is the first use of electrochemically produced ultra-low-carbon cement within data center construction, aiming to reduce embodied carbon in digital infrastructure projects.
Sublime Systems states that its cement is manufactured using an electrochemical process, which contrasts with legacy fossil-fuel-driven chemical reactions and is designed to avoid carbon emissions associated with traditional Ordinary Portland Cement production. Dr. Leah Ellis, CEO and Co-founder of Sublime Systems, said, “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.” She noted that loading docks represent ideal test sites due to their exposure to significant wear and stress, offering a demonstration of the material’s durability.
Bethany Brantley, Head of Sustainability at Stack Infrastructure, stated, “As the first deployment of Sublime’s low-carbon cement in a data center application, it marks a milestone for the industry. It sets a new standard not only in how we build, but in how we lead, with tangible benefits for the environment, our clients, and the local communities we serve.”
Stack Infrastructure explains that this pilot complements its broader strategies to reduce embodied carbon across data center construction. Additional measures include the adoption of supplementary cementitious materials (SCMs) and the integration of mineralized carbon dioxide solutions into concrete mixes. The company reports these efforts represent a comprehensive approach to climate responsibility within the data center sector.
