Svante Inc., LafargeHolcim, Oxy Low Carbon Ventures LLC (OLCV), une filiale détenue à 100 % par Occidental, et Total ont annoncé leur intention de mener une étude conjointe pour évaluer la viabilité et la conception d’une installation de captage du CO2 d’échelle industrielle, à la cimenterie Holcim Portland à Florence, dans le Colorado, aux Etats-Unis.
Cette étude a pour objectif d’évaluer le coût d’un tel dispositif, qui serait conçu pour capter annuellement jusqu’à 725 000 tonnes de dioxyde de carbone, directement issu de la cimenterie LafargeHolcim. Ce dioxyde de carbone serait ensuite stocké définitivement en sous-sol par Occidental.
