Abstract
Provides an energy
assessment and a preliminary design of an industrial plant for the production
of 100 tons/day of hydrogen by sulfur-iodine thermochemical cycle. An economic
analysis is performed to assess the hydrogen production cost, assuming the use
of solar energy to power the process.
Accordingly, a double solar
facility is sized: a parabolic trough plant, for the mean temperature duties,
and a central receiver tower one for the higher temperature duties. The
efficiency of the thermochemical cycle by itself is about 34%. If this value is
associated with the electrical energy production, including the efficiency of
the solar plants, the total heat-to-hydrogen efficiency of 21% is obtained,
with a hydrogen production cost of about 8.3 €/kg.
