Document Description
This project has a Geothermal Grant and Loan Program grant to prepare and execute a small scale demonstration of CO2-based geothermal power generation. The project includes installation of a closed loop Carbon Dioxide (CO2) driven turbine, utilizing an existing geothermal well. Cooled CO2 will be sent down the center if the well, heated by the hot rock outside the well, then the heated CO2 will go up the well shaft and turn the turbine, the CO2 will then be re-cooled, and circulated again.

Notice of Exemption
Exempt Status
Categorical Exemption
Type, Section or Code
S: 15301, 15303
Reasons for Exemption
This project is exempt because it consists of the operation and minor alteration of existing facilities of both investor and publicly-owned utilities used to provide electric power, and because it consists of construction and location of small structures not involving use of significant amounts of hazardous substances and not exceeding 2500 square feet in floor area. The Great Basin Unified Air Pollution Control District filed a CEQA Notice of Exemption for this project on April 27, 2017 that stated, "The existing facility produces electricity using geothermal fluid. The only possible emissions from this CO2 turbine is CO2. Facility already reports CO2 emissions to the state of California.
