The U.S. Department of Energy has announced $36 million in awards for 18 projects as part of the High Intensity Thermal Exchange through Materials and Manufacturing Processes (HITEMMP) program, as well as the final OPEN+ Cohort, High Temperature Devices. These project teams seek to develop new approaches and technologies for the design and manufacture of high temperature, high pressure, and highly compact heat exchangers and components.
Durable and affordable higher-temperature heat exchangers could make energy conversion much more efficient, which in turn could reduce fuel consumption, system footprint, capital and operational cost, and emissions.
Heat exchangers are critical to efficient thermal energy use in a variety of applications, including electricity generation, nuclear reactors, transportation, petrochemical plants, waste heat recovery, and many more. HITEMMP projects will 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.
