Chemical hydrides due to their light weight and high storage capacity are considered to be
promising hydrogen storage materials for both mobile and stationary applications.
Ammonia Borane (AB) is a novel material with very high hydrogen content (19.6 wt %) per
mass. The decomposition of AB takes place in three steps at desorption temperatures of
about 100 �C, 140 �C and above 1000 �C respectively releasing 1 mol of hydrogen in each
step. The major obstacle towards the use of AB as a hydrogen store is its irreversibility and
slow kinetics. With the additives the decomposition temperature could be reduced and the
kinetics can be improved. Effect of addition of Zeolites on decomposition of Ammonia
Borane at different temperatures is reported in this paper. It was observed that the kinetics
behaviour is greatly affected by addition of Zeolites with considerable reduction in the
induction or warm-up period
