Abstract: A method is disclosed for the generation of hydrogen and oxygen from a liquid feed stream comprising water. The method includes passing an electric current through an aqueous electrolyte solution. Water is fed to the aqueous electrolyte solution by forward osmosis, wherein the aqueous electrolyte solution is brought into contact with a first side of a forward osmosis membrane and the liquid feed stream comprising water is brought into contact with a second side of the forward osmosis membrane. Water permeates through the forward osmosis membrane from the second side to the first side by a difference in osmotic pressure between the liquid feed stream and the aqueous electrolyte solution. Further, a device is disclosed for carrying out the above method.
