Just read about the development of C02 capture technology using sea water and a carbonate substrate such as lime stone. Basically large volumes of sea water are sprayed onto a gas flow as it passes over or through a limestone substrate. The wet limestone reacts with the CO2 forming carbolic acid.

                     CO₂(g) + CaCO₃(s) + H2O(l) => Ca2+(aq) + 2HCO₃-(aq)

Potentially this technology will form a very cost effective carbon capture mechanism for coastal fossil fuel power stations. The use of BETE's spray nozzle in flue gas desulpherisation to prevent acid rain is well established and some 70% of US power stations and many in the UK have BETE nozzles in their desulpherisation plants. Obviously we will be delighted if this technology starts to be widely used as well.

For more information please read this paper from the Institute of Marine Studies, University of California.
