AMMONIA AS A POSSIBLE STORAGE MOLECULE FOR HYDROGEN
The storage of hydrogen is one of the key technical challenges for future energy industry and applications. Due to the high density of hydrogen that can be stored (17 wt％), chemical storage of hydrogen is one of interesting alternative to the many possibilities explored in last years. Liquid ammonia is seen as a interesting carrier for hydrogen due to its unique advantages over other liquid fuels, i.e. well-established infrastructure, production of inherently COx-free hydrogen1. Recently, renewed interest in this catalytic process has increased by the growing requirement of high quality hydrogen for fuel cells. Ammonia decomposition is interesting for the release of high purity hydrogen to feed fuel cells, most possible for on-site of the fuelling station. Another possible application of ammonia decomposition is the direct ammonia fuel cell. All those applications place highest demands on the catalyst operating at relatively low temperature, since high temperatures are highly unfavourable for on-board hydrogen generation, and even for stationary decomposition units, a high temperature reactor would require additional energy. This talk focus on the possibility of ammonia as a hydrogen storage molecule and on its catalytic decomposition as a key step for the release of hydrogen.
