  • Monitoring CO2 Leakage Sites on the Ocean Floor

    The multinational energy company Equinor operates a CO2 capture and storage facility that injects about 1 megaton per year of the greenhouse gas into an offshore sandstone aquifer deep below Norwegian waters. Undersea storage of the gas presents less risk for humans in case of accidental leakage compared with storage on land because the vast ocean acts as a buffer for the released CO2.
