It is essential that CO₂ separation and capture technologies become widely available to achieve the sectorial reduction ambitions. Several of these breakthrough technologies are being evaluated at large scale by the power and the cement sector.

CEMEX actively participates in various R&D collaborative efforts with different sectors to develop technologies to capture, utilize and/or store carbon, as well as other carbon reduction technologies. Some of these projects include:

• LEILAC targets carbon capture as its main outcome by developing an indi­rect calciner that enables pure CO₂ capture as it is released from limestone.
• eCOCO2 aims to set up a CO₂ cap­ture and conversion process using renewable electricity and water steam to directly produce fuels, tar­geting a CO₂ per-pass conversion of greater than 85%, energy efficiency of more than 85%, and net specific demand of less than 6 MWh/t CO₂. The demonstration phase intends to produce over 250 g of fuel per day.
• OXYFUEL seeks to integrate and adapt technology for capturing pure CO₂ for use according to the current cement production process and equipment.

Additionally, led by the National Petroleum Council (NPC) in the US, we are collaborating to conduct a study to provide the Department of Energy (DOE) with advice on Carbon Capture, Use, and Storage (CCUS).
