Electrochemical Hydrogen Storage in Lightweight Electrode Materials
Investigation of magnesium and carbon-based compounds
Omschrijving
Energy storage has nowadays become an important
issue due to the fact that equipment is being
scaled down while energy consumption is
generally not reduced. This has also resulted in
ever increasing environmental issues. A possible
answer might be found in using clean fuels such
as hydrogen. Currently, US Department of Energy
(DoE) targets for the year 2010 aim at 6 wt.% of
hydrogen stored on system level. Presently,
energy densities achieved by commercial Metal-
Hydrides reach only 1.2 wt.%. Further
development of new lightweight hydrogen storage
materials, based on magnesium or carbon,
can provide a possible route to higher
gravimetrical storage capacities. The research
described in this work shows that magnesium-
based alloys show excellent reversible and fast
hydrogen storage properties with capacities up
to 6.7 wt.%. This makes these materials very
promising candidates when considering
applications where hydrogen storage plays an
important role. The described in-depth
investigation should help shed some light on
this new and exciting field of lightweight
materials, and should be especially useful to
professionals in academic and research
environments.
