Investment Announcement
CRH Ventures announces strategic investment in Sublime Systems
CRH Ventures is delighted to confirm a strategic investment partnership with Sublime Systems, the pioneering U.S. based company in the field of sustainable cement production. This partnership marks a significant step forward in our commitment to advancing decarbonisation within the construction industry.
Sublime Systems is at the forefront of developing an innovative electrochemical, near-ambient-temperature approach to cement production. This technology aims to replace traditional kiln processes and achieve a 90% reduction in cement’s CO2 emissions at full commercial scale. By utilising primarily calcium-rich minerals and industrial byproducts like slags and kiln dusts, Sublime Systems produces hydraulic, ASTM C1157- compliant cement that is a 1:1 replacement for portland cement in concrete. Its process can break down solid feedstocks into individual constituent elements, yielding other industrial co-products and leading to near-zero waste.
Head of CRH Ventures Eduardo Gomez said "Our investment in Sublime Systems aligns seamlessly with the focus we’re placing on decarbonising construction. Sublime Systems’ approach to cement production has the potential to significantly reduce CO2 emissions, offering a differentiated solution in the market. The recent award from the U.S. Department of Energy's OCED program, underscores the promise of their technology."
The partnership will provide CRH with priority site selection rights for full-scale plant development in key markets, as well as material offtake from Sublime Systems' first commercial-scale plant for deployment and market-building initiatives.
Sublime Systems is currently engaged in front-end loading (FEL) engineering for a 30,000 tpa demo-scale project to achieve Technology Readiness Level (TRL) 7, a significant milestone in its development path.
