Basics
- This page compared electricity and hydrogen as power storage methods for cars
- Also look into Biofuels (use standard combustion engines, can be made from hydrogen (and thus even electricity) via GTL )
- Marcin's Take: Hydrogen will clearly win. Fuel cells are not needed - direct combustion will win
Hydrogen
- Can be done via fuel cell to electric drivetrain, or combustion similar to a standard Internal Combustion Engine powered car
Advantages
- Relitively Quick Refueling
- Higher Capacity/energy Density? (need hard data)
- Easily replaceable storage parts (tanks vs lithium ion batteries)
Disadvantages
- Infastructure
- Electricity is everywhere, and charging stations are not hard to add
- Hydrogen alone is uncommon, but can be made relitively easy by steam reforming
- It then requires compressors and/or cyrogenic coolers
- Storage Methods:
- Either Ultrahigh Pressure Compression or Cryogenic, both requiring expensive fueling stations, and storage tanks
Electric
Advantages
- No conversions needed (ie no fuel cell or ICE)
- Common Infastructure
Disadvantages
- Expensive batteries
- Slow Recharge Time
- Less Capacity/Energy Density? (need hard data)
