Supercritical CO2 Brayton for Compact High Efficiency Power Generation

Sandia National Laboratories, New Mexico, United States

TECHNOLOGY SUMMARY

Sandia National Laboratories is developing a thermal-to-electric power conversion technology in a configuration called the recompression closed Brayton cycle (RCBC). The closed Brayton cycle is a proven power technology that uses carbon dioxide as opposed to seam, thereby increasing conversion efficiency compared to the steam Rankine cycle.

Primary Application Area: Conventional Energy

Technology Development Status: Prototype

Technology Readiness Level: TRL 4

FIGURES OF MERIT

Value Proposition: This technology will reduce the costs of energy production, reduce greenhouse gas emissions, and is applicable to any heat source. The thermal-to-electric conversion efficiency of the closed Brayton cycle can be dramatically higher than other cycles for applications such as nuclear energy, concentrated solar power, and waste heat sources.
