Episode notes
E-Fuels Suit Aviation Niche Only
- E-fuels may address niche sectors like aviation needing liquid fuels with high energy density.
- Their production is energy-intensive and impractical to scale before abundant cheap renewables exist.
Electrolyzer Costs Challenge Green Hydrogen
- Electrolyzers, crucial for green hydrogen, are rising in price contrary to earlier cost decline predictions.
- Large economies of scale make small modular electrolyzers unlikely to drastically lower costs.
Batteries Could Electrify Aviation
- Battery improvements may enable most long-distance air travel electrification by 2040.
- Hybrid airplanes may halve fuel use, reducing aviation’s hydrogen reliance substantially.
