Ammonia is a potentially rich source of hydrogen for fuel cells. All it needed was a good catalyst that would reform NH3 into Hydrogen and Nitrogen.The HYPERMEC 10010 is a ruthenium-based catalyst which delivers ammonia conversion at 400°C. This catalyst is available in powder or pellet form. The current pre-commercial base metal catalyst HYPERMEC 10510 will offer ammonia conversion at a lower cost at slightly higher temperatures, and is expected to be available to customers by the end of 2008._GCC
Pure hydrogen is difficult to handle, for small vehicular uses. But hydrogen reformed from methane, methanol, ammonia, etc. is extremely manageable.
storage of ammonia has many problems..toxicity and flammability/explosion among them.
ReplyDeleteBetter: urea. NH2-CO-NH2, catalyzed to CO2 & NH3 by common enzyme urease.
Stores easily as a very conc water solution.
