Recuperated Supercritical Carbon Dioxide Brayton Power Cycle System
Project Innovation + Advantages:
Thar Energy will develop a next-generation metallic compact recuperator, a type of heat exchanger, capable of stable and cost effective operation at 800°C (1562°F) and above 80 bar (1160 psi). A metallic superalloy capable of withstanding high temperature and pressure will be employed to fabricate the heat exchanger using a novel stacked sheet manufacturing technique. The cost-effective heat exchanger design could enable design enhancement with improved structural integrity and thermal performances for high-efficiency, modular, and cost-competitive recuperated supercritical carbon dioxide (sCO2) Brayton power cycle systems. Thar Energy will also develop and test an efficient, cost-effective, and sustainable power generation system. The new system will use its developed recuperator and novel high temperature components, such as a high-temperature primary heat exchanger and high-efficiency reciprocating expander capable of operations above 800°C and 300 bar.
HITEMMP projects will enable a revolutionary new class of heat exchangers and innovative approaches to advanced manufacturing with applications for a wide range of commercial and industrial energy producers and consumers.
High performance, efficient heat exchangers would increase industrial productivity, supporting domestic industries. The developed manufacturing techniques for high temperature materials could strengthen U.S. leadership in advanced manufacturing.
More efficient electricity generation and industrial processes could significantly reduce emissions by enabling more efficient operations.
