Hydrogen storage is one of the enabling technologies, which
may be combined with hydrogen production and fuel
cell ones and provide one of the future ultimate carbon-free
energy storage solutions, for portable, onboard and stationary
applications. Researchers have done studies on Mg-based
materials for on board hydrogen storage (for fuel cell vehicles)
for decades. From the study of downsizing effect on kinetics
and thermodynamics, the author found that hydrogen storage
kinetics can be significantly enhanced by nanosize and catalysts,
however, desorption thermodynamics (enthalpy and entropy)
in nanostructured system does not change with downsizing
and catalysis in the size range of 5-300 nm. This means that
nanostructured MgH2-Mg system is not suitable for onboard
hydrogen storage inwhich case aworking temperature of below
100 degrees is needed. Nevertheless, Mg-basedmaterials show
promising properties for stationary energy storage due to the
advantages of low cost, high energy density and no need for
low working temperature. Some recent results from the author
on Mg-based materials focusing on kinetics enhancement,
thermodynamics tailor and capacity improvement will be
discussed in this work.
