Hydrogen technology for automobiles in the 21
st
century towards more secure and cleaner
environment
H
ydrogen is expected to play an important role in future energy scenarios, as it could resolve growing concerns about
world’s energy supply, security, air pollution, and greenhouse gas (GHG) emissions. Hydrogen production from
renewable resources can potentially reduce the CO
2
emissions. Hydrogen is a non-toxic, clean energy carrier that has high
specific energy on a mass basis (e.g., the energy content of 9.5 kg of hydrogen is equivalent to that of 25 kg of gasoline).
Worldwide H
2
production is ~ 500 billion.m
3
annually with ~6.5 EJ (1EJ=109 GJ) of energy. The exhaust from the H
2
vehicles
is water. Early developments (from 1960) were focused on H
2
-IC engine vehicles. In 2001, BMW introduced H
2
-IC engine
vehicles. Significant advancements in fuel cell technologies and initiatives offered by the US DOE, world-wide governmental
agencies, and industries led to the development of prototypes H
2
-fuel cell electric automobiles. In the last 10-15 years many
auto manufacturers, including Toyota, Honda, Hyundai, Ford, General Motors, Daimler Chrysler and others have developed
fuel cell vehicles, some are already becoming commercial. Many countries are installing hydrogen fueling stations but they are
relatively few clustered around big, highly populated cities. Low pressure, solid state metal hydrides, such as LaNi
4.8
Sn
0.2
, have
already been developed for space applications, but they are very heavy and have low gravimetric hydrogen density of ~2 wt.%
for vehicular applications. Light weight and low pressure (LP) complex hydrides, such as Mg(BH
4
)
2
, Li
2
NH-LiNH
2
and other
light weight systems with ~10 to 18 wt.% H capacity are still in developmental stages. Non withstanding the LP solid state
systems, Toyota and other manufacturers started using high pressure (~700 bar) H
2
, carbon fiber composite, cylinders which
appear to be functional in the latest vehicles under normal operations. The H
2
based vehicular technological developments, and
challenges associated with this technology will be presented.
