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 matters

Why fuel dominates OpEx in steam generation, and how fuel types vary across regions

How the cost of steam affects overall cost of delivered products

Why resistive boilers reached maturity ahead of heat pumps

Why standardized, air-source heat pumps are emerging as an attractive alternative to resistive boilers

The role of thermal storage combined with renewable PPAs

Why Addison thinks waste heat is a distraction for decarbonization
