The plant would represent the first commercial application of a novel renewable energy technology called Carbon Dioxide Plume Geothermal, or CPG. The technology was developed at the University of Minnesota and is licensed to university startup Heat Mining Co. LLC , based in Rapid City, South Dakota.
The CPG plant would generate electricity from carbon dioxide that is injected underground, in a practice known as enhanced oil recovery (EOR), to increase the amount of crude oil extracted from a field that typically is nearing the end of its productivity.
The electricity generated using the CPG technology would be used to replace power provided by conventional sources, resulting in emission-free electricity at lower cost, extending the lifespan of economical oil extraction, according to its developers.
