About Sublime Systems
Sublime Systems is leading a swift and massive transition to a clean cement manufacturing future. Sublime’s breakthrough electrochemical process avoids the pollution caused by ordinary portland cement’s use of fossil-fueled kilns and limestone feedstock. Sublime instead extracts reactive calcium and silicates from abundant raw materials at ambient temperature, to make ASTM C1157-compliant Sublime Cement™, a 1:1 replacement for OPC in concrete. Because it does not require carbon capture, Sublime’s technology offers a clear path for cost-competitive clean cement manufacturing at scale. Sublime was founded at MIT in 2020 by Dr. Leah Ellis and Prof. Yet-Ming Chiang, both respected experts in materials science, electrochemical systems, and sustainability research. The company has raised over $200M in funding from leading tech investors, global cement majors, and cooperative agreements with the U.S. Department of Energy’s ARPA-E, IEDO, and OCED award programs. It currently operates a Somerville, MA-based pilot plant with a >250 TPY nameplate production capacity and is developing its 30,000 TPY first commercial facility in Holyoke, MA.
