13 based approaches as well as literature, physics, and experience-based alloy design approaches to identify candidate MPEA (multi-principal element alloy) compositions that show unprecedented creep strength at high temperatures while providing ductility at room temperature. The HITEMMP program entails new approaches to the design, fabrication, and testing of compact and efficient heat exchangers operating at high temperatures (>800C hot side, >300C cold side) and across a high-pressure differential (>80 bar hot side, >250 bar cold side) utilizing supercritical CO2 as a heat transfer fluid. 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, andmuchmore. The project teams are building a 50 kWth prototype unit targeting minimum of 40,000 hours of mean time to failure utilizing refractory alloys as well as ceramics and various additive manufacturing strategies. Other project cohorts I am directing include new materials and systems for DAC (Direct Air Capture) to remove CO2 from thin air, high-efficiency magnetic materials with no or little amount of rare earth elements to make powerful motors and inductors, new high-entropy catalysts for ammonia oxidation, additively manufactured carbon-composite based light-weight automobile body materials, novel approach to dry industrial products without evaporatively drying the water, low-cost grid-scale batteries using only abundant materials, and costeffective geothermal resource exploration using ambient seismic imaging. Why did you invite Prysmian Group to speak at ARPA-E’s 2022 Energy Innovation Summit? I organized a panel discussion on "Rethinking solutions for the resilience, reliability, and security of electric grid infrastructure" at the 2022 ARPA-E Energy Innovation Summit to discuss transformative ideas and technologies that can quickly bring cost-effective grid resilience, reliability, and security solutions to the U.S. grid infrastructure, with an emphasis on addressing associated environmental justice issues. It was obvious that I needed to include experts from the power utility sector, materials and equipment, and engineering and construction on the panel. During the course of developing my undergrounding program, I had the opportunity to meet Dr. Srini Siripurapu and learn that Prysmian Group has commercialized a wide range of electrical cable types, power equipment, and monitoring equipment, and has been at the forefront of testing new ideas and innovations in Europe and the United States. As a result, I thought it would be beneficial for Summit attendees to hear Prysmian’s ideas and perspectives on improving the reliability, resilience, and security of our future grids. Furthermore, I discovered that Prysmian Group has never attended the ARPA-E Energy Innovation Summit. I am pleased that not only Dr. Srini Siripurapu attended the Summit as a panelist, but that more Prysmian Group representatives were able to attend the ARPA-E Energy Innovation Summit. I visited and witnessed an extremely busy Prysmian Group exhibition booth where many inspiring conversations and networking took place, and I look forward to seeing the Prysmian Group again at our future ARPA-E Energy Innovation Summit events.
