SublimeSystems low-carbon cement as a drop-in replacement for Portland cement in concrete

SublimeSystems low-carbon cement, Sublime Cement, is produced with electrochemistry, cutting out the very high firing temperatures required for producing ordinary Portland cement (OPS). Sublime’s cement is made by electrically charging a bath of chemicals and calcium silicate at its plant. This creates reactive lime and avoids the release of CO2. Hydrogen and oxygen are produced as byproducts. They are in development and currently scaling up the technology to industrial-scale production. Image SublimeSystems.
