Basalt is considered as a promising host rock for CO2 sequestration due to its composition with minerals cations such as Ca, Mg, and Fe. Basalt is composed of olivine, pyroxene, and plagioclase feldspar which react with dissolved CO2 and form carbonate minerals, which can trap the injected CO2 in secure solid forms. CO2 sequestration in basalt involves various ways and techniques that capitalize on the reactivity of basaltic minerals to capture and securely store carbon dioxide. This chapter discusses about different approaches for CO2 sequestration in basalt, elucidating the mineralization process. It also highlights its potential as an effective carbon storage media.
