Ammonium carbonate as hydrogen source for fuel cells?

This is also an idea that I don't know if it is good or not.  Now, if you were to heat ammonium carbonate solution in water, it would give off ammonia and carbon dioxide.  Get rid of the carbon dioxide and then crack the ammonia for hydrogen.  Run the hydrogen through the fuel cell to produce electricity to run a vehicle.

The advantage here is safety.  Ammonia carbonate is a lot safer to store than anhydrous ammonia.  It is also safer than aqueous ammonia solution.

The carbon dioxide may be captured and recycled, if that's practical.  If it is not, it may still be rendered carbon neutral by using biologically produced carbon dioxide.

If there's a downside, I don't see it yet.

Update:

The idea for this came from a Solve for X video, which covered a methodology for cleaning up waste water.

Update:

This will become the original post for the series Killer App for Molten Salt Reactors.  Called it post #1.  There are several posts that lead to post x, which is the killer app post.  I won't count nor link them all.
