Novel concept for the conversion of wheat straw into hydrogen, heat, and power: A preliminary design for the conditions of Washington State University

► A design for a stepwise thermochemical process that converts wheat straw into pyrolysis vapors and a syngas is presented. ► The syngas is converted into CH4 via methanation, or used as a fuel for molten-carbonate fuel cells to generate electricity. ► In our design, excess pyrolysis vapor can supplement natural gas for a steam production at Washington State University. ► An integrated heat balance of our design yields excess waste heat that can be sent to greenhouses.
