| 20110100002 | PROCESS TO OBTAIN THERMAL AND KINETIC ENERGY FROM A GEOTHERMAL HEAT SOURCE USING SUPERCRITICAL CO2 - Methods and systems for extracting geothermal energy from an underground hot dry rock reservoir using supercritical carbon dioxide are disclosed. In a first step, the methods and systems utilize a heat exchanger in a binary system to heat a secondary fluid that is used to perform work. In a second step, the supercritical carbon dioxide is transferred to a pseudo turbine (e.g., a free-piston linear engine) to perform additional work through expansion. | 05-05-2011 |
