  1. Contact Information Mary Anne Alvin National Energy Technology Laboratory Research Group Leader  Advanced Materials Research Separation & Fuels Processing Division Office of Research and Development Pittsburgh, PA 412-386-5498 maryanne.alvin@netl.doe.gov Materials and Component Development For Advanced Turbine Systems

  2. Experience / Expertise • Thirty years of experience in the area of advanced energy systems at Westinghouse and Siemens Westinghouse. • As a Fellow Scientist, program management and principal investigator efforts between 1987-2004 encompassed procurement and successful conduct and completion of programs in the area of high temperature, particulate removal, porous ceramic (oxide- & nonoxide-based, monolithic & CFCC/CMC), intermetallic, and metal/superalloy filter materials and component development/bench-scale assessment; performance in domestic and off-shore pilot- and demonstration-scale, pressurized, gasification and combustion coal-fired power generation facilities targeted for hot gas filtration commercialization & integration with the gas turbine power island. • In 2000, technology areas were expanded to include development of advanced high temperature catalyst systems and substrate supports for combustion turbines, and gas separation membrane components. • In 2005 joined DOE/NETL where primary focus includes ORD program development and execution via conduct and management of both internal and collaborative external materials technology efforts for 2015 advanced land-based syngas, hydrogen-fired, and oxy-fuel gas turbines. • Project includes >25 professionals in industry, small businesses, universities, and the National Laboratories. • Project encompasses materials development, aerothermal heat transfer, and NDE technology areas. • Chair of the Materials TAT Technology Team for the Power Propulsion Systems Alliance (DOD, DOE, NASA, WPAFB, Army, Navy, and FAA Collaboration). • ORD Representative on NETL’s PM Turbine Technology Team & NETL’s PM Gasification Technology Team.
