Abstract
A system and method for power generation and CO2 sequestration include a fuel cell system configured to generate power using natural gas (NG), a container configured to store liquid natural gas (LNG), and a fluid processor configured to convert LNG received from the container into NG and to convert exhaust output from the fuel cell system to dry ice by transferring heat between and the LNG and the exhaust.
Claims20
A combined system for power generation and CO2 sequestration, comprising:
- a fuel cell system configured to generate power using natural gas (NG);
- a container configured to store liquid natural gas (LNG);
- and
- a fluid processor configured to convert LNG received from the container into NG and to convert exhaust output from the fuel cell system to dry ice by transferring heat between and the LNG and the exhaust.
1 more element
A method of combined power generation and CO2 sequestration, comprising:
- providing natural gas (NG) to a fuel cell system to generate power;
- cooling exhaust output from fuel cell system using a first heat exchanger;
- compressing the cooled exhaust output from the first heat exchanger using a compressor;
- cooling the compressed exhaust output from the compressor using a second heat exchanger provided with liquid natural gas (LNG) to generate liquid CO2;
- converting the liquid CO2 into dry ice;
- vaporizing the LNG to generate the NG;
- and
- providing the generated NG to the fuel cell system.
