About
Sublime Systems is a Somerville, Massachusetts-based materials company that has developed an electrochemical process to produce ordinary portland cement (OPC) without the CO2 emissions inherent in conventional kiln-based manufacturing. Founded in 2020 as a spinout from MIT, Sublime''s process uses renewable electricity to drive chemical reactions that produce calcium silicates — the active binding agents in cement — at ambient temperature, eliminating the calcination and combustion steps that account for approximately 8% of global CO2 emissions. The resulting cement is chemically identical to conventional OPC and functions as a direct drop-in replacement in standard concrete mixes.
Michigan's largest utility with $12.7B FY2024 revenue; $25B electric capex through 2027; 80% CO2 reduction by 2040; DT Midstream spun off 2022; data center demand growth in Detroit region.
