In this episode, Madelyn O’Farrell talks with Celadyne founder and CEO Gary Ong about how a new membrane material can unlock the full potential of electrochemistry for hydrogen, long-duration energy storage, and critical material separations. Gary shares his journey from PhD researcher to startup founder after big corporates passed on his invention, then explains how Celadyne’s membrane dramatically reduces hydrogen crossover, boosting fuel-cell durability and cutting critical materials in electrolyzers. They dive into the grid-capacity crunch facing hyperscalers, why hydrogen plus electrolyzers and fuel cells makes sense at 50 - 100+ MW scale, and how salt-cavern storage enables multi-day and even week-long clean power from solar. Gary also unpacks the geopolitical race over hydrogen technology between the U.S. and China, the strategic role of hydrogen for defense and fuel logistics, and closes by arguing that the real constraint to building next-generation energy and AI infrastructure in the U.S. is workforce development and the shortage of skilled trades.
