The development of reliable, efficient and low cost renewable
energy power plants is a possible solution of the today environmental,
social and economic issues [1]. Among renewables
biomass can represent a useful alternative [2e4]. Hydrogen, as
energy vector, is one of the most promising options because it,
differently from electricity, can cover all the energy needs (e.g.
storage, extra gravitational propulsion); furthermore it is
“clean” and it allows a distributed production from local resources
[5e8]. However it is still produced especially from
