Improving basalt wettability to de-risk CO2 geo-storage in basaltic formations

CO2 geo-storage in basaltic formations has recently been identiﬁed as a viable option to rapidly dispose large quantities of CO2 , hence mitigating anthropogenic CO2 emissions. However, it has been shown that basalt is weakly water-wet or intermediate-wet at typical storage conditions, which reduces...
