GreenFire Energy Making Headway on CO2-Based Plant (ThinkGeoEnergy)
 |
The project, which received a US Department of Energy grant in 2010, is the world’s first attempt at a real-world CO2-based geothermal energy project, putting to use years of computer modeling and academic debate. St. John’s Dome is a unique site for this type of project as it sits on 450MM tons of shallow CO2 deposits. The goal is to extract and compress these locally-available deposits, and inject them into the hot basement formation containing geothermal heat with one single test well.
