Ty Neises

Ty Neises serves as Researcher IV in Mechanical Engineering at the National Renewable Energy Laboratory (NREL), working within the Center for Energy Conversion and Storage Systems and Thermal Sciences Group since joining in 2011.

His educational background includes:

• Master of Mechanical Engineering from the University of Wisconsin
• Bachelor of Mechanical Engineering from the University of Wisconsin

Neises specializes in concentrating solar power (CSP) systems with core expertise in thermal fluid dynamics, supercritical carbon dioxide (sCO₂) power cycles, and high-pressure receiver design. His research integrates thermo-economic modeling, thermal energy storage solutions, and performance optimization for next-generation solar thermal plants. Current projects focus on advancing sCO₂ Brayton cycles and recompression cycle configurations for improved efficiency in CSP applications.

Analysis of his 2022-2025 publications reveals consistent emphasis on CSP system optimization, particularly through techno-economic evaluation of thermal storage integration and novel power cycle designs. Key themes include linear Fresnel collector modeling, power tower receiver development, and sCO₂ cycle innovations for combined heat and power applications.

Neises actively contributes to NREL's System Advisor Model (SAM) development and collaborates extensively within the Thermal Sciences Group on concentrating solar power research initiatives.
