Floating Offshore Carbon Neutral Electric Power Generating System Using Oceanic Carbon Cycle

Abstract

An oceanic offshore system and method for generating electric power which comprises a structure positioned at an offshore location. A power generating module is mounted on the structure, the power generating module including a turbine, an electric power generator coupled to the turbine, and a generating source of power fluid for the turbine resulting from the combustion of a fossil fuel. There is a capture system connected to the generating source for transferring carbon dioxide combustion gases to a subsea location for sequestration of CO 2 .

What is claimed is: 
     
         1 . A system for generating electric power comprising:
 an oceanic offshore structure;   an electric power generating system mounted on said structure, said power generating system including:
 an electric power generator; 
 a driver powered by combustion process of a fossil fuel, said driver being connected to said generator; and 
 a capture system connected to said combustion process for transferring carbon dioxide combustion gases from said combustion process to a subsea location. 
   
     
     
         2 . The system of  claim 1 , wherein said driver comprises a turbine. 
     
     
         3 . The system of  claim 2 , wherein said driver comprises a gas turbine. 
     
     
         4 . The system of  claim 1 , wherein said capture system includes a conduit having a first end operatively connected to said driver to receive said carbon dioxide combustion gases therefrom, and a second end positioned at a subsea location. 
     
     
         5 . The system of  claim 4 , wherein said capture system further includes a compression system for compressing said carbon dioxide combustion gas introduced into said conduit. 
     
     
         6 . The system of  claim 1 , further comprising an electric power substation mounted on said offshore structure for receiving electric power output from said generator. 
     
     
         7 . The system of  claim 6 , further comprising:
 an electric power transmission system operatively connected to said substation and a remote location to transmit electric power to said remote location.   
     
     
         8 . A method of generating electric power comprising:
 positioning a structure at an oceanic offshore location;   mounting an electric power generating system on said structure, said generating system having an electric power generator and a driver drivingly connected to said generator;   combusting a fossil fuel to power said driver with a byproduct of carbon dioxide combustion gas;   capturing said carbon dioxide combustion gases and transferring to a subsea location.   
     
     
         9 . The method of  claim 8  wherein said driver is one of a gas combustion turbine or steam turbine. 
     
     
         10 . The method of  claim 8 , further comprising:
 compressing said carbon dioxide gas prior to transferring said carbon dioxide gas to said subsea location.   
     
     
         11 . The method of  claim 8 , further comprising:
 transmitting electric power from said electric power generating system to a remote location.   
     
     
         12 . The method of  claim 11 , wherein said remote location is on land.
