A novel strategy for sequestering atmospheric CO2: The use of sealed microalgal cultures located in the open-oceans

Theoretical calculations using demonstrated CO2 sequestration efficiencies and production rates of microalgal batch cultures suggest that 4 cylindrical enclosures, each with a diameter of 100 m and a depth of 40 m would be able to sequester the CO2 emitted by a 500 MW coal-fired generating plant. On a grander scale, using the same CO2 consumption rates and the enclosures described above, roughly 14,000 enclosures could reduce the CO2 in the troposphere by 1 ppm on a yearly basis, representing half of the total CO2 added to the atmosphere annually.
