Most climate tech discussions focus on electricity, but seventy percent of industrial heat comes from burning fossil fuels. In this episode, we examine how companies like Climeworks and Siemens Energy are tackling the hardest part of decarbonization: high-temperature process heat. We look at the specific economics of electric boilers versus green hydrogen, why steam is the unsung hero of manufacturing, and the real barrier preventing widespread adoption in sectors like cement and chemicals. With global industrial emissions hitting record highs in early 2026, understanding the thermal transition is critical for anyone tracking energy infrastructure.
