Sublime Systems is a mid-sized manufacturing company based in Somerville, Massachusetts, founded in 2020 at MIT by Dr. Leah Ellis and Prof. Yet-Ming Chiang. The company has developed an electrochemical process that operates at ambient temperature to produce cement, reducing emissions associated with traditional Portland cement and removing the need for carbon capture. Its Sublime Cement is intended as a one-to-one substitute for ordinary Portland cement in concrete, and the firm runs a pilot plant in Somerville with a nameplate capacity exceeding 250 tons per year. 

In the construction materials market, Sublime aims to provide a low-carbon alternative that can scale toward cost-competitive clean cement manufacturing. A notable recent development is a collaboration with Stack Infrastructure to pilot Sublime’s cement at a data center campus in Virginia, illustrating a real-world application beyond its pilot facility.
