Hydrogen production plays a very important role in
the development of hydrogen economy. Hydrogen gas production
through solar energy which is abundant, clean and renewable is
one of the promising hydrogen production approaches. This
study overviews the available technologies for hydrogen
production by using solar energy as main source. Photochemical,
electrochemical and thermochemical processes for producing
hydrogen with solar energy are analyzed from thermodynamic,
environmental, and economic points of view. It is concluded that
developments of improved processes for hydrogen production via
solar resource are likely to continue in order to reach competitive
hydrogen production costs. Hybrid thermochemical processes
where hydrocarbons are exclusively used as chemical reactants
for the production of syngas and the concentrated solar radiation
is used as a heat source represent one of the most promising
alternatives: they combine conventional and renewable energy
representing a proper transition towards a solar hydrogen
economy
