Technology Description:

MIT will develop a high performance, compact, and durable ceramic heat exchanger. The multiscale porous high temperature heat exchanger will be capable of operation at temperatures over 1200°C (2192°F) and pressures above 80 bar (1160 psi). Porosity at the centimeter-scale will serve as channels for the flow of working fluids. A micrometer-scale porous core will be embedded into these channels. A ceramic co-extrusion process will create the channels and core using silicon carbide (SiC). This core design will significantly improve heat transfer and structural strength and minimize pressure drop, enabling very high power density.

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.


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.


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