Episode notes
What Process Heat Actually Does
- Process heat mainly raises temperatures to drive chemical reactions or phase changes in industry.
- These functions determine the form and temperature quality of energy required for each process.
Steel’s Emissions Come From Chemistry
- Steelmaking combines heat and a reducing agent; the reducing chemistry often dominates emissions.
- Direct reduced iron and electric arc melting shift emissions from heat to hydrogen or electricity supply.
Cracking Needs High-Grade Indirect Heat
- Steam cracking is high-temperature indirect heating, pushing tube metallurgy limits above ~800°C.
- Electrically heated crackers or methanol feedstock routes lower temperatures and ease decarbonization.
