GE leads a USD2.5 MM project through ARPA-E’s HITEMMP

GE Research is leading a USD2.5 MM project through the Advanced Research Projects Agency’s (ARPA-E) High Intensity Thermal Exchange through Materials and Manufacturing Processes program (HITEMMP) to develop a high temperature, high pressure and super-compact heat exchanger that would enable cleaner, more efficient power generation in both existing and next-generation power plant platforms.

The new heat exchanger being developed by the team will leverage a unique, high-temperature capable, crack-resistant nickel superalloy, designed specifically for the additive manufacturing process by the team at GE Research. Oak Ridge National Laboratory will leverage their well-known expertise in corrosion science to test and validate the materials long-term performance. When completed, the heat exchanger will enable increased thermal efficiency of indirectly heated power cycles such as supercritical carbon dioxide (sCO2) Brayton power generation, reducing energy consumption and emissions. In addition, high-temperature capable heat exchangers offer new opportunities in advanced aerospace applications.

The goal of the 2.5-year program is to develop and demonstrate the 3D printed heat exchanger at full temperature and pressure capabilities.
