Robert Dagle is the Applied Catalysis II Team Leader, Senior Research Engineer, and Project Manager within the Energy Processes & Materials Division (EP&MD) of the Energy and Environment Directorate (EED) at PNNL. Mr. Dagle manages a team of staff members engaged in the development of innovative catalytic processes for the upgrading of biomass or fossil derived oxygenated intermediates (e.g., ethanol, syngas) to produce renewable or low carbon fuels and chemicals. Mr. Dagle manages multiple projects sponsored by the Department of Energy's Bioenergy Technologies Office (DOE-BETO). Current projects are aimed at converting biomass- and waste-derived ethanol to value-added fuels and chemicals, including butadiene, olefins, lubricants, high octane gasoline, and jet fuel blendstock. Mr. Dagle also manages a CRADA project sponsored by the Fuel Cell Technology Office (DOE-FCTO) aimed at developing a process for the direct conversion of methane to low-CO2 hydrogen and valuable solid carbon co-product.

Mr. Dagle has research experience with multiple catalytic processes which include steam reforming of hydrocarbons and bio-derived oxygenates, conversion of bio-derived light oxygenates to fuels or chemicals, preferential CO oxidation and selective CO methanation for PEM fuel cell applications, catalytic combustion, water-gas-shift catalysis, reactive distillation, conversion of biomass-derived aqueous products to value-added fuels and chemicals, syngas conversion technologies (e.g., synthesis of alcohols, transportation fuels, synthetic natural gas, and hydrogen), and chemical synthesis (e.g., acetic acid, olefins, alcohols). Mr. Dagle also has experience with integrating engineered catalysts within novel reactor architectures for process intensification purpose (e.g., micro/mesochannel process technology). His work has benefited clientele in both the government and private industry arena and has resulted in more than 50 journal articles and book chapters and numerous presentations. Mr. Dagle also serves on the steering committee for the Chemical Catalysis for Bioenergy (CCB) Consortium, a DOE national lab-led R&D consortium dedicated to overcoming catalysis challenges for the conversion of biomass and waste resources into fuels, chemicals, and materials. Mr. Dagle has 15 issued U.S. patents and one R&D 100 Award (2014).
