Sublime Systems has secured up to $87 million (£69 million) in funding from the US Department of Energy (DOE) for its innovative low-carbon cement project

In a groundbreaking move toward greener construction practices, Sublime Systems has secured up to $87 million in funding from the U.S. Department of Energy (DOE) for its innovative low-carbon cement project.

The funding, part of the Industrial Demonstrations Program under the Bipartisan Infrastructure Law, aims to accelerate the development of sustainable solutions in energy-intensive industries.

Sublime Systems, a Massachusetts-based startup, is pioneering a revolutionary method of producing fossil-fuel-free cement.

Their electrochemical process bypasses the traditional reliance on fossil fuels and extreme temperatures, significantly reducing carbon emissions associated with cement production.

The company's first commercial facility, set to open in Holyoke, Massachusetts, by early 2026, will produce up to 30,000 tons per year of low-carbon cement. 

This initiative aligns with broader efforts to combat climate change and transition industries toward net-zero emissions.

Sublime Systems CEO and Co-Founder Leah Ellis said the DOE funds will allow it to more rapidly scale up production. “Access to sufficient capital for industrial-scale demonstrations is the single biggest obstacle preventing breakthrough innovations from reaching the scale humanity needs to combat the climate crisis,” said Ellis in the release.

Sublime's commitment to community engagement and environmental justice is evident in its partnership agreements with local labour unions and initiatives to create quality jobs in the Holyoke region.

The company's Community Benefits Plan prioritizes economic and environmental justice for disadvantaged groups, aligning with the DOE's mandate for grant applicants.

The selection of Sublime Systems for funding underscores the DOE's dedication to advancing decarbonization technologies in key industries such as concrete construction.

With strong demand already evident for their sustainable cement, Sublime is poised to lead the way in revolutionizing the cement industry while fostering economic growth and environmental sustainability.
