Hydrogen Storage
Hydrogen is an energy carrier like
electricity.
The former has the advantage that it
can be stored. It is this
property of hydrogen that
attracts so much interest in energy
research. Hydrogen which can be
generated e.g via electrolysis of
water or steam reformation of methane
may well be stored in high-pressure tanks. Where the volume
and the weight of tanks are not of
concern as in some stationary applications, this form of hydrogen storage is
quite acceptable. For most applications ( stationary as well as
mobile )
a denser form of hydrogen /energy
storage, comparable to that of
a gasoline tank in a car , would be required.
Research effort in the group ,within the general framework depicted
above,
focuses on thermodynamics and
kinetics of metal- hydrogen reaction.
We concentrate on processing routes that allow
easy control of material
chemistry. Materials of concern
are often nanostructured, therefore,
techniques yielding such structures
are of particular interest.
We are partners in NESSHY ,ie.
integrated project (FP6) on solid state storage of hydrogen and
in a national (DPT-YUUP) project on hydrogen-fuel cell.

Hydrides as foaming agent
Foaming process requires an ingredient that would decompose within a specific temperature interval
where the liquid metal has the right viscosity. In Aluminum this is usually TiH2.
