Materials for Hydrogen Storage |
|
|
There is renewed interest in high-efficiency hydrogen storage
materials with a view to a possible role for these in future
hydrogen-powered vehicles, fuel cells, etc. At UCSD, we are
embarking on a comprehensive program of research on
understanding the processes by which hydrogen can be absorbed,
stored and desorbed in materials, using neutron and x-ray
scattering, infrared and photoemission spectroscopy. Using
neutron and x-ray reflectivity, neutron diffraction and
inelastic neutron scattering, we hope to be able to understand
the kinetics of hydrogen absorption and desorption, and the
structural and dynamical effects effects of hydrogen
incorporation into the lattices of several materials which seem
to show a promising hydrogen to host weight ratio. We also plan
to study how the addition of catalysts affects the absorption
process. Materials which will be studied include light atom
hydrides, alanates, and organometallic framework compounds. This
work will be carried out collaboratively between our group and
the
Schuller and
Basov groups in the UCSD Physics Department, and
researchers at Brookhaven, Los Alamos and Lawrence Berkeley
National Laboratories. |
