Reality: Hard to electrify aviation, shipping, long-haul trucking. Need liquid fuels. Green fuels = solution.
Time to complete: 20 minutes
Cost: Free
What you learned: Significant liquid fuel dependency remains even with EVs
Here’s the green fuel reality: Aviation, shipping, long-haul trucking can’t easily electrify. Need energy-dense liquid fuels. Green fuels (sustainable aviation fuel, biofuels, e-fuels) provide carbon-neutral alternative. $1 trillion SAF market by 2050. Current premium 2-5x conventional fuel dropping to parity by 2030-2035.
The opportunity:
- SAF (Sustainable Aviation Fuel): $1T market, 50-200% growth annually
- Biodiesel: Mature, 10-20% returns
- E-fuels: Synthetic gasoline from H₂ + CO₂, breakthrough potential
- Green ammonia: Shipping fuel, $100B+ market
Green fuels = last mile of energy transition. Essential + profitable.
The Value Proposition: Green Fuels Enable Decarbonization
Sustainable Aviation Fuel (SAF)
The aviation problem:
- 2-3% of global CO₂ emissions
- Growing 4-5% annually pre-COVID
- Battery aircraft only viable <500 km (tiny fraction of flights)
- Hydrogen aircraft 2040s at earliest
- Need liquid fuel for decades
SAF solution:
- Drop-in replacement (no engine modifications)
- 70-85% emissions reduction vs conventional jet fuel
- Can blend 50% today, 100% by 2030
- Derived from waste oils, biomass, atmospheric CO₂
SAF Production Pathways:
1. HEFA (Hydroprocessed Esters and Fatty Acids):
- Source: Used cooking oil, animal fats, plant oils
- Current: 70% of SAF production
- Cost: 2-3x conventional jet fuel
- Scalability: Limited (feedstock constraints)
2. Fischer-Tropsch:
- Source: Biomass, waste, atmospheric CO₂ + H₂
- Cost: 3-5x conventional (currently)
- Scalability: High (abundant feedstock)
3. Alcohol-to-Jet:
- Source: Ethanol from corn, sugarcane, cellulose
- Cost: 2-4x conventional
- Scalability: Medium-high
Economics:
- Current SAF: $3-5/liter ($450-750/ton)
- Conventional jet: $0.60-1.00/liter ($90-150/ton)
- Premium: 3-8x
But cost dropping fast:
- 2025: $3-5/L
- 2030: $1.50-2.50/L (2-3x premium)
- 2035: $1.00-1.50/L (parity!)
- 2040: Potentially cheaper (if scaled + carbon priced)
Market:
- Current: 600 million liters SAF annually (0.2% of jet fuel)
- 2030: 20-30 billion liters (6-10%)
- 2050: 300+ billion liters (>50%)
- Investment: $1+ trillion
Returns: Early SAF producers/investors capturing 15-30% annually as mandates + demand explode
Biodiesel and Renewable Diesel
Biodiesel: Fatty acid methyl esters from vegetable oils/animal fats Renewable diesel: Hydroprocessed oils (chemically identical to petroleum diesel)
Current production: 50+ billion liters globally Growth: 8-12% annually
Feedstocks:

- Land use constraints
Solution: Focus on waste oils + algae (no food competition, no deforestation)
E-Fuels (Power-to-Liquid)
Process: Renewable electricity → hydrogen (electrolysis) → combine with captured CO₂ → synthetic gasoline/diesel/jet fuel
Advantages:
- Carbon neutral (CO₂ from atmosphere, burned, returned to atmosphere = cycle)
- Drop-in replacement (works in existing engines)
- Energy storage (convert excess renewable electricity to storable liquid)
- No feedstock constraints (just need electricity, water, CO₂)
Challenges:
- Expensive currently ($5-10/liter)
- Energy intensive (40-50% round-trip efficiency)
- Requires massive renewable electricity + cheap electrolyzers
Timeline:
- 2025: Demonstration plants
- 2030: Commercial at $3-5/L
- 2040: Scaled at $1.50-2.50/L
- 2050: Cost-competitive $1-1.50/L
Market potential: $500B+ by 2050 if costs drop as projected
Investment opportunity: Early e-fuel companies (very high risk/reward)
