Abstract
A Carbon Capture and Storage (CCS) system and method generates electricity by applying a supercritical fluid to an expansion turbine connected to a generator. The expansion turbine sends the fluid from the expansion turbine to a compressor after expansion. The compressor compresses the fluid output by the expansion turbine into a desired supercritical state and the compressed fluid is injected into one or more first sequestration reservoirs in a reservoir formation.
Claims20
A method, comprising:
- generating electricity by applying a supercritical fluid to an expansion turbine connected to a generator, wherein generating includes outputting the fluid from the expansion turbine after expansion;
- compressing the fluid output by the expansion turbine into a desired supercritical state;
- and
- injecting the compressed fluid into one or more first sequestration reservoirs in a reservoir formation.
A Carbon Capture and Storage (CCS) system, comprising:
- a plurality of sets of reservoir injection equipment, each set of reservoir injection equipment including an isolation valve, each set of reservoir isolation equipment configured to connect through a borehole to a sequestration reservoir in a reservoir formation;
- power generation equipment having an expansion turbine connected to a generator, the power generation equipment connected to one or more of the sets of reservoir injection equipment, the power generation equipment configured to receive supercritical fluid;
- a compressor connected to a motor and to the expansion turbine;
- and
- a computer system having a processor and a memory, the memory including instructions that, when executed by the processor, cause the processor to:
- generate electricity via the generator by applying the supercritical fluid to the expansion turbine connected to the generator, wherein generating includes outputting the fluid from the expansion turbine after expansion;
- compress the fluid output by the expansion turbine into a desired supercritical state via the compressor;
- and
- injecting the compressed fluid into one or more first sequestration reservoirs in the reservoir formation.
A non-transitory computer readable medium storing instructions that, when executed by a computer cause the computer to:
- generate electricity by applying a supercritical fluid to an expansion turbine connected to a generator, wherein generating includes outputting the fluid from the expansion turbine after expansion;
- compress the fluid output by the expansion turbine into a desired supercritical state;
- and
- inject the compressed fluid into one or more first sequestration reservoirs in a reservoir formation.
