Design and operating considerations for a shell-and-plate, moving packed-bed, particle-to-sCO2 heat exchanger

•Heat transfer coefficients for particle/sCO2 exchangers can approach 400 W m−2 K−1.•Reduced particle channel width should be prioritized in moving bed heat exchangers.•Particle conductivity and void fraction are identified as areas of improvement.•Heat exchanger cost below $150 kWt−1 requires heat...
