How does a steam cracker actually use heat internally?

Process heat accounts for two-thirds of industrial emissions. Yet talk of decarbonization often misses the engineering realities that separate viable solutions from expensive dead ends. To understand process heat and the technologies capable of providing it, I’m joined by returning guest Jesse Huebsch, a process engineer specializing in chemical plants. Our conversation ranges from steel and cement to plastics and ammonia, examining which processes can be electrified, where steam dominates, and why the most advanced high-temperature reactor designs may not be the answer.
