Addison Stark thinks waste heat is a waste of time. The real opportunity, he argues, is decarbonizing industrial steam, which accounts for roughly 30% of industrial heat in the U.S. But doing that means deploying alternatives to the fossil fuel boilers industry currently relies on.So how do you clean up steam? And why does Addison think waste heat is overhyped?In this episode, Shayle talks with Addison Stark, the CEO — or as he likes to call himself, chief boiler maker — of industrial heat pump startup AtmosZero. They dive into topics like:The difference between saturated and superheated steam — and why it mattersWhy fuel dominates OpEx in steam generation, and how fuel types vary across regionsHow the cost of steam affects overall cost of delivered productsWhy resistive boilers reached maturity ahead of heat pumpsWhy standardized, air-source heat pumps are emerging as an attractive alternative to resistive boilersThe role of thermal storage combined with renewable PPAsWhy Addison thinks waste heat is a distraction for decarbonizationResources:Joule: To decarbonize industry, we must decarbonize heatThe Green Blueprint: Rondo Energy’s complicated path to building heat batteriesCatalyst: Solving the conundrum of industrial heatCredits: Hosted by Shayle Kann.
