Abstract
A powered system is disclosed including a power block, an exhaust system configured to receive exhaust gas from the power block, a carbon capture system and a heat recovery system. The exhaust system is configured to couple the carbon capture system to the power block. The carbon capture system is configured to extract CO2 from the exhaust gas. The heat recovery system is configured to receive the extracted CO2 from the carbon capture system for providing heat energy to and from the power plant system.
Claims6
A powered system comprising:
- a power block;
- an exhaust system configured to receive exhaust gas having an exhaust stream from the power block;
- a carbon capture system;
- and
- a heat recovery system,
- wherein the exhaust system is configured to couple the carbon capture system to the power block,
- wherein the carbon capture system is configured to extract CO2 from the exhaust gas,
- wherein the heat recovery system comprises a pump for receiving the extracted CO2, a recuperator in connection with the pump, an exhaust heat recovery heat exchanger and an expander, wherein the extracted CO2 is transferred to the recuperator by the pump, and then to the exhaust heat recovery heat exchanger, wherein the exhaust heat recovery heat exchanger is disposed in the exhaust stream of the exhaust system to heat the extracted CO2 and the extracted CO2 being supercritical CO2 (sCO2) following the exhaust heat recovery exchanger, wherein heat energy is harnessed from the supercritical CO2 (sCO2) by the expander to provide the heat energy to and from the powered system, and
- wherein the heat recovery system further comprises:
- a thermal storage for receiving the supercritical CO2 (sCO2) from the exhaust heat recovery heat exchanger, where the expander receives heat energy from the thermal storage,
- wherein the thermal storage is configured to power the power block and provide and receive energy from the exhaust heat recovery heat exchanger.
