Hydrogen has the highest mass energy density of any fuel:
120 MJ/kg (LHV) 144 MJ/kg (HHV)
At ambient conditions (300 K, 1 atm.):
the energy content of 1 liter of H2 is only 10.7 kJ,
three orders of magnitude too low for practical applications.
1. What are the options available for storage?
2. What are the theoretical limits to storage density and how close can we come?
3. How do we organize a development program to achieve adequate stored energy in an efficient, safe and cost-effective manner?
Increasing molecular wt.
Hydrogen density is nearly the same in all fuels.
This narrow range suggests a natural benchmark for comparison of storage performance.
Energy Density MJ/liter
CNG, gasoline, methanol.
Parallel development of fuel processor and onboard H storage.
Part of Mining Industry of the Future initiative.
