  • Clathrate ice thermal transport for ocean thermal energy conversion
    Patent number: 7900452
    Abstract: A substance is added to cold ocean water in a cold water pipe of an Ocean Thermal Energy Conversion (OTEC) system. The substance raises the freezing point of the ocean water in a cold water heat exchanger of the OTEC system, thereby forming an ice slurry. The substance is added at the depth of the apparatus. The ice slurry is transported from the point of addition in the cold water pipe to the cold water heat exchanger at the surface.
    Type: Grant
    Filed: June 19, 2008
    Date of Patent: March 8, 2011
    Assignee: Lockheed Martin Corporation
    Inventors: Robert J. Howard, John W. Rapp, Patrick Grandelli, Joseph C. Van Ryzin
