(WorldCement) Total is stepping up its research into Carbon Capture, Utilisation and Storage (CCUS) technologies by signing a multi-year partnership with UK start-up Cambridge Quantum Computing (CQC). This partnership aims to develop new quantum algorithms to improve materials for CO2 capture. Total’s ambition is to be a major player in CCUS and the group currently invests up to 10% of its annual research and development effort in this area.
To improve the capture of CO2, Total is working on nanoporous materials called adsorbents, considered to be among the most promising solutions. These materials could eventually be used to trap the CO2 emitted by the group’s industrial operations or those of other players (cement, steel etc.). The CO2 recovered would then be concentrated and reused or stored permanently. These materials could also be used to capture CO2 directly from the air (Direct Air Capture or DAC).
The quantum algorithms which will be developed in the collaboration between Total and CQC will simulate all the physical and chemical mechanisms in these adsorbents as a function of their size, shape and chemical composition, and therefore make it possible to select the most efficient materials to develop. Currently, such simulations are impossible to perform with a conventional supercomputer, which justifies the use of quantum calculations.
