Carbon capture and storage (CCS)

It is reported that the technology, CCS is of absorbing the greenhouse gas (CHG) CO2 in some matrix at the emission points and store the gas under or on the sea bed instead of discharging in to the atmosphere is an excellent idea from the global warming and climate change considerations. The emission points are the environmental discharge points of the power plants based on fossil fuel. Alternatively, it is reported that the gas can also be stored underground in vacant or disused natural gas fields.

Parallel can be seen in the underground disposal of radioactive wastes. Risk of leakages is similar in both the situations. In an event of any leakage of CO2 in the sea water, there will be a change the sea water acidity (increase) destroying the marine life. Hence, as in the case of radioactive waste, the disposal in the sea bed of the CO2 canisters should be banned internationally. The only alternative will be as in the case of high-level radioactive waste, the well-sealed CO2 canisters can be disposed off in stable and deep geological formations without much risk of any leakages reaching the environment.
