Technology Description:

International Mezzo Technologies will design, manufacture, and test a compact, nickel-based superalloy supercritical carbon dioxide (sCO2) recuperator (a type of heat exchanger). The recuperator will incorporate laser-welded micro tubes and function at 800°C (1,472°F) and 275 bar (3,989 psi). Currently, the cost of recuperators for power systems operating in these conditions is prohibitive. Laser welding micro tubes offers a low-cost approach to fabricating heat exchangers, which could increase the economic competitiveness of sCO2 power cycles. Mezzo’s program could provide a pathway to manufacture relatively inexpensive heat exchangers for high temperature-high pressure applications.

Potential Impact:

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.

Security:

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.

Environment:

More efficient electricity generation and industrial processes could significantly reduce emissions by enabling more efficient operations.

Economy:

HITEMMP technologies could enable more cost-effective, efficient, and compact modular power generation systems for multiple applications.
