The Carbon Plume Geothermal (CPG) technology used by Heat Mining Company from South Dakota in the U.S., will allow using sequestered carbon dioxide instead of geothermal fluids for geothermal power generation.
A recent article describes how a South Dakota, U.S. based firm is planning to use sequestered carbon dioxide instead of geothermal fluids to produce geothermal power. We reported on this before but this article describes it quite nicely.
The company called Heat Mining Company has developed a technology that allows using the carbon dioxide captured in carbon capture and storage (CCS) process as the underground working fluid to extract geothermal heat for additional electricity production and/or district heating.
In the process, the CO2 can be permanently stored underground, resulting in a geothermal power plant with not only a neutral, but even a negative carbon footprint.
The Carbon Plume Geothermal (CPG) technology used by the company is expected to produce renewable electricity far more efficiently than conventional geothermal systems, all while effectively sequestering the carbon dioxide far underground. It is a win-win for developing much more renewable geothermal power and reducing excess carbon dioxide in the atmosphere, by sequestering it.”
