In a process for producing hydrogen or syngas by methanol cracking, whereby methanol is catalytically decomposed into hydrogen and carbon monoxide in an endothermal reaction, said reaction takes place in a reactor with direct inductive heating in the reaction zone. The heating is obtained by passing an alternating current through a metallic coil located inside the reactor or by using induction heated catalyzed hardware in the shape of a ferromagnetic structure, which is coated with an oxide impregnated with the catalytically active phase.
