Abstract

A hydrogen economy is thought to be one of the ultimate carbon-neutral energy solutions. For a future scenario, one may obtain hydrogen from renewable power, for instance, wind or solar energy; this hydrogen can be provided to fuel cell component to supply electricity and heat. For this energy storage and utilization route, one enabling technology is hydrogen storage because hydrogen as energy carrier is a gas state at normal temperature and atmosphere conditions and the energy density of hydrogen gas is low. Therefore, a critical step is to find one hydrogen storage technology with low cost and high energy density. Mg-based materials are very promising candidates for hydrogen storage due to the great abundance of Mg in earth’s crust, high hydrogen storage capacity (7.7 wt% for ...
