A method for producing hydrogen from a plant source is disclosed. The method includes contacting a crude carbohydrate material obtained from the plant source with water and a catalyst at a temperature and pressure sufficient to decompose at least a portion of the crude carbohydrate material to form a vapor mixture of gases including hydrogen, and separating hydrogen from other gases present in the vapor mixture.

We claim: 1. A method for producing hydrogen from a plant source, comprising:obtaining a plant fiber material obtained by separating the fiber material from starchy material of an agricultural grain;if needed, adding water to bring the fiber material to a moisture level of about 70%;heating the fiber material in a sealed reactor to a temperature of between about 135° C. and 225° C. for about 30 to 60 minutes to form a heat and pressure treated plant fiber material;separating from the heat and pressure treated fiber material an aqueous liquid mixture containing oligosaccharides and a solids fraction;contacting the aqueous liquid mixture containing oligosaccharides with a catalyst at a temperature and pressure sufficient to decompose at least a portion of the oligosaccharides in the mixture to form a vapor mixture of gases including hydrogen; andseparating hydrogen from other gases present in the vapor mixture.
