Hydrogen and Gas Turbines

History and fundamentals of hydrogen combustion in gas turbines for aircraft propulsion and electric power generation.  What is real and what is hype?

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.

ITU Faculty of Mechanical Engineering


ITU Faculty of Mechanical Engineering takes pride in having close to 100 years of Mechanical Engineering tradition, and has currently 33 Professors, 12 Associate Professors, 24 Assistant Professors and 15 Lecturers as Faculty members. At present, we have over 2000 undergraduate students, all of which were selected among the top ~0.5% of the ~2.3 million students taking the nationwide university entrance exam annually.

Founded in 1933, the Faculty of Mechanical Engineering received its current name in 1944. With the university reform in 1933, the Institute of Electricity and Machines of the Istanbul University was replaced by the Electro-Mechanic Department; and by doing so our Mechanical Engineering education, which still continues, began 87 years ago. 11 years later in 1944, the name of the institution was changed to Istanbul Technical University and under it a separate school/college of Mechanical Engineering was founded with the current name: “Faculty of Mechanical Engineering“.

Our faculty is one of the oldest institutions in our country that carries out education and research activities in the field of mechanical engineering. The different engineering branches it hosts have developed and become a faculty. in 1969; Faculty of Naval Architecture and Marine Sciences, in 1983; The Faculty of Textile Technologies and Design and the Faculty of Aeronautics and Astronautics gained their independent status.In the first years, the Mining Engineering department, which was part of the basic sciences and general engineering courses instruct within the scope of the Faculty of Mechanical Engineering, became an independent faculty in 1953.

ITU Faculty of Mechanical Engineering performs research and education in the design, development and production planning of all types of mechanical and energy transformation systems. Our 75 Faculty members are performing research and development in a wide range of areas related to both immediate needs of the industry and also cutting edge science for future technologies and applications. Our research areas include, but not limited to, Automotive Industry, Petrochemical Industry, Robotics, Textile Industry, Defense Industry, Reverse Engineering, Clean Energy, Renewable Energy, Underground Gasification, MEMS, Nanotechnology, Pharmaceutics, and Biomolecular Engineering.

With its gorgeous Ottoman era building providing extensive lab space, massive laboratory and research investment performed in the past 87 years, and the recent addition of the 1500 m2 big Dr. Keskin Keser student lab building, the Faculty of Mechanical Engineering has one of the most extensive educational and research laboratories in Turkey and provides its students with top quality Mechanical Engineering education in a gorgeous historical building located at a prime location in the very heart of Istanbul.
