Abstract: The invention relates to a process for generating hydrogen, comprising decomposing in a reaction vessel aqueous alkali formate in the presence of a transition metal-containing catalyst system dissolved in one or more organic solvent(s), characterized in that said organic solvent(s) comprise at least one solvent which is water-immiscible, thereby releasing hydrogen and forming bicarbonate in the aqueous phase, and separating the catalyst-containing organic solvent(s) from said bicarbonate. Also disclosed are apparatuses for carrying out hydrogen generation.

Abstract: The invention provides a process for the production of hydrogen, comprising catalytically decomposing a concentrated aqueous solution of potassium formate in a reaction vessel to form bicarbonate slurry and hydrogen, discharging the hydrogen from said reaction vessel, and treating a mixture comprising the bicarbonate slurry and the catalyst with an oxidizer, thereby regenerating the catalyst. Pd/C catalysts useful in the process are also described.
