Abstract :
The specific technological challenges associated with the delivery of CO2 into the deep ocean are qualitatively discussed. Since the projected effectiveness of CO2 oceanic sequestration so far requires ocean depths of kilometer(s) and large flow rates, the necessary pipelines bear some similarities with the cold seawater conduits of Ocean Thermal Energy Conversion (OTEC). A unique perspective is thus provided by examining the history of OTEC seawater systems. Design criteria specific to CO2 delivery pipelines are also mentioned, as well as their impact on future design work.
