Strategy to Enhance Geological CO ₂ Storage Capacity in Saline Aquifer

Geological CO2 storage is an emerging topic in energy and environmental community, which is, as a commonly accepted sense, considered the most promising powerful approach to mitigate global carbon emissions during transition net-zero. Of geological media initially cover saline aquifers, oil gas reservoirs, coal beds, potentially basalts, up now only first two choices have been proven be capable sites successfully implemented at pilot/commercial scales. Here, tandem papers propose novel strategies for time, by synthesizing utilizing new high-dryness foam, enhance capacity aquifer reservoirs. In this paper, foam synthesized injected into aquifers explore enhancement, with unique foam-induced advantages of sweep area expansion efficiency improvement. Such idea specifically evaluated validated through series static analytical dynamic performance experiments. With optimum surfactant concentration 0.5 wt%, foaming volume quality are determined 521 mL 80.81%, respectively, also shows excellent salt tolerance 45,000 ppm Na+, 25,000 Ca2+, Mg2+. Moreover, water consumption decreases from 464.31 g/mol 25% 67.38 85% using foam. Overall, newly could effectively concurrently diminish consumption, therefore realizing win-win environment economic benefits.
