hydrogen has no toxic orgreenhouse gas emissions Fuel cells using
hydrogen achieve greaterthan 50% efficiency Cost per mile will be
comparable to gasoline Hydrogen has more energy per pound thanany
other fuelLawrence Livermore National Laboratory3 4. Hydrogen at
low temperature and high pressure reduces weight,volume and cost of
storage Prototypes have passed Department of Transportation
andInternational Organization for Standardization (ISO) tests (fire

the tank depends onduration of non-use (time parked). No hydrogen
loss until after 10days of parking. Vented gas can be catalytically
reacted to waterwithout hazard.Lawrence Livermore National

National Laboratory Lowest ownership cost: Cryogenicvessels use 2-
4x less carbon fiber thanhigh pressure gaseous H2 tanks. Rapid
refueling at high density: 5minute high density refueling (74
-90g/L) possible with LH2 pump Safe: Low expansion energy,
steeljacket provides secondary protection,low on-road operating
pressure, fewerpressure cycles due to longer drivingrange LLNL
