1. A reactor system for production of hydrogen from a feedstock comprising methanol in the presence of a catalyst under methanol cracking reaction conditions, said reactor system comprising:
a supply of feedstock comprising methanol and water;
a structured catalyst arranged for catalyzing said methanol cracking reaction of said feedstock, said structured catalyst comprising a macroscopic structure of an electrically conductive material, said macroscopic structure supporting a ceramic coating, wherein said ceramic coating supports a catalytically active material;
a pressure shell housing said structured catalyst, said pressure shell comprising an inlet for letting in said feedstock and an outlet for letting out product gas, wherein said inlet is positioned so that said feedstock enters said structured catalyst in a first end of said structured catalyst and said product gas exits said structured catalyst from a second end of said structured catalyst;
a heat insulation layer between said structured catalyst and said pressure shell;
at least two conductors electrically connected to said structured catalyst and to an electrical power supply placed outside said pressure shell, wherein said electrical power supply is dimensioned to heat at least part of said structured catalyst to a temperature of at least 150° C. by passing an electrical current through said macroscopic structure;
an outlet for a product stream comprising hydrogen.
