Abstract
A method of producing hydrogen from sewage sludge comprising: (a) introducing sewage sludge into an anaerobic digester containing a multiplicity of interfacing pairs of cathodes and anodes spaced from 0.5 to 1.5 inches from one another; (b) maintaining anaerobic conditions within said digester to cause the digestion of said sewage sludge; (c) applying an electric potential between said cathodes and anodes to create a current density of from 0.25 to 2.0 amps/square foot at said electrodes in order to suppress the formation of methane and enhance the production of hydrogen; and collecting gas containing hydrogen produced from said digester.
