Is ammonia an efficient hydrogen storage system?

Question

Is ammonia an efficient hydrogen storage system?

Answer 1

No.  Giving up the bound hydrogen does not come without some form of energy being put in.

Answer 2

Yes, it is.

Also ammonia can be stored in the salt Mg(NH3)6Cl2  efficiently...

Answer 3

Surely, hydrogen is efficiently stored via ammonia production.

It's really a great hydrogen storage (about 3500 kwh per m3)

-ammonia from hydrogen

Today the new industrial processes produce ammonia from hydrogen with an efficiency of about 80-85 %.

-Hydrogen from ammonia.

Ammonia is easily cracked into hydrogen and nytrogen.

The process requires around 15 kj of energy per mol of produced H2, so almost always it can be easily recored from the lost heat produced from hydrogen utilize(fuel cells,  turbo-gas, etc...)
