in my previous post, i listed 3 general CO2 gas storage geotechnology strategies … i’ll discuss the pros & cons of each individually in the upcoming posts …

1. CO2 stored in gaseous form and pumped or injected deep below the ground, into various geological formations such as saline aquifers, exhausted gas fields, coal beds, etc.
PROS:
* currently, this option is considered the safest … the injected CO2 gas is expected to react with the local bedrock and naturally form inert mineral carbonates via a process known as mineral carbonation … this is a natural geological process which, under normal conditions, occurs over a span of thousands of years … hence, the injected CO2 gas will theoretically exert no detriment to the local and regional geology while becoming permanently stored below the Earth’s surface … more…
