CO 2 neutrality by 2045 requires increasing the currently worldwide achieved CO 2 storage volume (40 Mt/y) to the order of tens of Gt/y. With current storage techniques, CO 2 often remains in the gaseous phase, thus, free to spread underground risking unwanted leakage in the distant future. As an alternative, the mineralization of CO 2 in basalts, where the vast majority (>90%) of the carbon is mineralized and fixed in carbonates within two years, offers a permanent safe storage as a solid (e.g. CarbFix, Iceland).<br />The international joint project PERBAS (ACT4) with partners from Norway, USA and India aims to pave the way for the commercialization of large-scale, permanent CO 2 sequestration into marine basalt complexes off the coast of Norway and India. The project seeks solutions for reservoir selection, CO 2 transport, injection and monitoring. PERBAS will investigate the feasibility of supercritical CO 2 injection, using water in the pore space, in order to avoid the requirement to inject 20 ...
