University of Minnesota Plans Construction of First Carbon Dioxide Plume Geothermal Plant

Finance & Commerce in Minnesota reports a University of Minnesota (U of M) startup expects construction to begin next year on a pilot plant that would produce electricity from geothermal and otherwise wasted energy while also boosting production from a Canadian oil field.

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 U of M and is licensed to U of M 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.
