The idea is to bind the CO2 in chemically stable forms that can be stored underground


Storage of the CO
2 is envisaged either in deep geological formations, or in the form of mineral carbonates. Deep ocean storage is not currently considered feasible due to the associated effect of ocean acidification.[8] Geological formations are currently considered the most promising sequestration sites. The National Energy Technology Laboratory (NETL) reported that North America has enough storage capacity for more than 900 years worth of carbon dioxide at current production rates.[9] A general problem is that long term predictions about submarine or underground storage security are very difficult and uncertain, and there is still the risk that CO
2 might leak into the atmosphere.[
