Sublime Systems Holyoke Facility

Sublime Systems is developing the Holyoke Project in Massachusetts, the first commercial-scale facility to produce true-zero cement using an electrochemical process that avoids both fossil-fueled kilns and limestone decomposition emissions. Backed by up to $87 million from the U.S. Department of Energy, the plant will scale from pilot operations (>250 tpa) to produce 30,000 tpa of Sublime Cement™ as early as 2026.
