Michael (Mike) Talmadge has contributed to safe fuel production operations, technology development, process modeling and analysis for twenty-five years. Mike supports the development of renewable fuel and chemical technologies at NREL through process modeling and techno–economic analysis of biomass to fuel and chemical pathways. He has contributed strategies for incorporating biomass–derived intermediates and finished fuel blendstocks into existing petroleum refining infrastructure through collaborative efforts with industry and projects at NREL. Mike has led initial development of a techno-economic analysis platform for assessing and comparing water treatment and reuse technologies in the National Alliance for Water Innovation. Currently, Mike is leading analysis efforts for low-emission hydrogen production from waste resources in Fossil Energy’s National Laboratory Gasification Consortium (NLGC). Outside of the NREL years, Mike spent over a decade in refinery fuels production and process technology development with ExxonMobil Research and Engineering Company, Valero Energy Corporation, and Johnson Matthey.
