High Intensity Thermal Exchange through Materials, and Manufacturing Processes

The projects that comprise ARPA-E's HITEMMP (High Intensity Thermal Exchange through Materials and Manufacturing Processes) program will develop new approaches and technologies for the design and manufacture of high temperature, high pressure, efficient, and highly compact heat exchangers. Heat exchangers are critical to efficient thermal energy exchange in numerous industrial applications and everyday life, with valuable applications in electricity generation, transportation, petrochemical plants, waste heat recovery, and much more. HITEMMP projects target heat exchangers capable of operating for tens of thousands of hours in temperatures and pressures exceeding 800°C and 80 bar (1,160 psi) respectively. This new class of hardware, designed and manufactured using novel techniques, topologies, and materials, would enable far greater exchanger efficiency, thus boosting the performance of many important industrial processes.

Additively Manufactured High Efficiency and Low-Cost sCO2 Heat Exchangers

The University of Maryland will design, manufacture, and test high-performance, compact heat exchangers for supercritical CO2 power cycles. Two innovative additive manufacturing processes will enable high performance. One facilitates up to 100 times higher deposition rate compared with regular laser powder additive manufacturing. The other enables crack-free additive manufacturing of an advanced nickel-based superalloy and has the potential to print features as fine as 20 micrometers. These developments could halve the fabrication cost and enable heat exchanger operations above 800°C (1472°F) and 80 bar (1160 psi). These systems could be applied to high-efficiency fossil energy, concentrating solar power, and small modular nuclear energy.
