Episode notes
Green Hydrogen's Importance
- Green hydrogen is crucial because 80% of global energy consumption is molecular, not electrical.
- Sectors like industry, transport, heating, and cooling rely on molecules, primarily fossil fuels.
Green Steel
- Steel production traditionally uses coal, contributing 7-9% of global CO2 emissions.
- Green hydrogen can replace coal, eliminating up to 95% of these emissions by attracting oxygen and emitting only water.
Hydrogen Planes
- Battery-powered aircraft face weight limitations.
- Hydrogen planes offer an emission-free alternative, showcasing green hydrogen's potential.
