Sublime Systems: An electrochemical pathway to cement

Sublime Systems is developing technology to electrify Portland cement manufacturing in a process that uses existing raw materials and facilities. Today each kilogram (kg) of Portland cement that is produced emits ~1 kg CO2 into the atmosphere. This CO2 is difficult to purify and capture as it is diluted and contaminated by other combustion gases.
