Episode notes
Industrial Heat and Emissions
- Industrial heat is a major source of carbon emissions, using a quarter of the world's fossil fuels.
- Decarbonizing industry, not deindustrializing it, is crucial for reducing global emissions.
Clean Heat for Decarbonization
- A new type of 'fire' or clean heat source is needed to decarbonize industries.
- This would allow continued production while significantly cutting emissions.
Electrification and Renewable Energy
- Electrified industrial heat is a promising solution, driven by falling wind and solar power costs.
- We have the capacity to build renewable energy at scale, but lack continuous supply.
