In this presentation, we will take a deep look at hydrogen and its use as a gas turbine fuel, starting with its history.  As will be shown, using hydrogen as a fuel, in one way or another, goes as far back as Goldsworthy Gurney and his “blowpipe” and “ammonia engine”.  Thereafter, we will follow with an introduction to the combustion of hydrogen, the practical problems it presents in modern Dry Low NOx (DLN) combustors, and the current status of the technology.  There are several methods of manufacturing hydrogen from water or from a hydrocarbon feedstock such as natural gas.  They will be introduced with a brief description and outlining of the challenges.  The presentation will conclude with numerical evaluations of what can realistically be expected from the hydrogen, in any “color” as a gas turbine fuel.

(518) 423-5751,

Dr. John Gülen is currently Senior Principal Engineer and Bechtel Fellow (elected in 2018) in Bechtel Infrastructure & Power, Inc., Reston, VA. Since 2012, Dr. Gülen has been active in supporting Bechtel for new technology assessment (e.g., supercritical CO2, concentrated solar power (CSP), carbon capture and energy storage), steam/gas turbine technical assessment for power plant and other turbomachinery projects (performance, operability, and risk analysis). Prior to Bechtel, Dr. Gülen worked in General Electric (2000-2012) in various roles and contributed to the successful design, operation, analysis and testing of landmark power system projects including the steam-cooled H-System (Baglan Bay 109H in 2003) and IGCC 207FB (Duke Edwardsport in 2006). Before joining GE, Dr. Gülen worked in Thermoflow, Inc. (1996-2000) as developer of world-class power plant simulation software products. In ESPC, Inc. in 1994-96, Dr. Gülen worked on the data analysis of the 110 MWe Compressed-Air Energy Storage (CAES) plant in McIntosh, AL,. Dr. Gülen has been an internationally recognized expert in cutting edge gas/steam turbine power plant technology with more than 25 years of experience. He was invited by the National Academy of Engineering (USA) to participate on drafting a report on gas turbine technology (2018). He recently participated as an invited panelist in the review of US DOE’s STEP Project ($112 million), a 10 MW sCO2 pilot plant (in San Antonio, TX). Dr. Gülen is frequently invited to review archival papers submitted for publication to top journals, e.g., ASME J. Eng. for GTs & Power.
