## Summary

Landon Mossburg, founder and CEO of Peak Energy, argues that sodium-ion batteries, specifically using sodium iron pyrophosphate (NFPP) chemistry, offer a compelling alternative to lithium iron phosphate (LFP) for stationary energy storage. He details how Peak Energy’s system achieves total installed cost parity with LFP by eliminating active cooling and reducing auxiliary power, despite having higher cell costs. Mossburg highlights NFPP’s superior thermal stability, safety profile, and cycle life as key drivers for lower operational expenditures and improved reliability in grid applications.
