Abstract
The systems and methods described herein reduce relatively high pressure supercritical COto a relatively low-pressure supercritical COusing a first COexpansion system positioned upstream of the thermal input system. The relatively low-pressure supercritical COpasses through the thermal input system and into a second COexpansion system. The first supercritical COexpansion system provides a first power output and/or the second COexpansion system provides a second power output. A COcompressor system converts the gaseous COexiting the second COexpansion system to the relatively high-pressure supercritical CO, at least a portion of which is returned to the first COexpansion system.
