Ammonia borane with high hydrogen content, 19.6 wt%, can be considered as an interesting candidate for hydrogen storage. Hydrolysis of ammonia borane and hydrogen production can be performed through thermal decomposition or catalytic hydrolysis under milder conditions. 

In the last few years, ammonia-borane (AB) has attracted increasing attention as a very promising chemical hydrogen storage material. AB is solid at room temperature and presents a potential capacity of 19.6 wt %... 

Thermolysis of ammonium borohydride produces nearly pnre hydrogen, with only a trace of borazine evolved at higher temperatures. The primary disadvantage of ammonium borohydride for many practical applications is its poor thermal stability. Ammonium borohydride slowly decomposes even at room temperature. Thus, methods to stabilize ammonium borohydride are needed to make this material practical for use in hydrogen storage applications. Ammonium borohydride also serves as a synthetic precnrsor for ammonia borane (AB), as discussed below.
