The Emeritus Club

As the voice of the gas turbine value chain in Europe and beyond, ETN highly values the knowledge and the practice of experts who have been active in the Gas Turbine community. It also honours the dedication of those who have reached retirement. It is of utter important to retain and benefit from this top-notch and well-tried expertise.

For those reasons, ETN has decided to establish the Emeritus Club, which gathers recognised experts from the gas turbine community. This Club will contribute to the work and the events of ETN, sharing their experience with the organisation and its members.



The current members of the Emeritus Club are:

David Abbott


David has over 40 years of experience in the fields of combustion and acoustics and for 20 years, he has been specialising in gas turbine combustion including  research, development and design roles for a major manufacturer (ALSTOM) and development, troubleshooting and operational support roles for a major utility gas turbine operator (E.ON, now Uniper). David Abbott also has a broad understanding of turbine technology and power generation cycle, through management  of  teams dealing with  aerodynamic and thermal design and development of gas and steam turbines and novel power generation cycles.

David holds a BSc Tech (Hons), Chemical Engineering and Fuel Technology  (University of Sheffield) and a PhD, Solid Propellant Admittance Measurement using Laser Anemometry  (University of Sheffield). He is a Chartered Energy Engineer (CEng), member of the Energy Institute (MEI) and member of the Institute of Acoustics (MIOA).

Fields of expertise:

Familiarity with a wide range of gas turbine types including: GE LM6000, 6B, 9FA; Siemens SGT100, SGT800, SGT5-4000F; ALSTOM GT24, GT26.

Currently interested in all aspects of gas turbine combustion particularly:

  • Impact of (gaseous) compositio on gas turbine operation, emissions, integrity, etc.

    • Grid natural gases, LNG, hydrogen, natural gas/hydrogen mixtures, off-specification natural gases, gasification gases, waste gases, etc.

  • Combustion acoustics (pulsations, dynamics, humming etc.)
  • Natural gas fuel quality specifications and standard

    • Hydrogen addition to natural gas grids


Manfred Klein


Manfred Klein has been working as a consultant on a range of environment and gas turbine energy issues, after retiring in 2013 from the Canadian government. He worked 6 years with the Gas Turbine Laboratory of the National Research Council, 16 years with Environment Canada, developed air emission rules for gas turbines using output-based standards and 11 years with the National Energy Board on gas compressor station certification. 


Manfred Klein is the former Chair of IAGT Industrial Gas Turbine Applications Committee and of ASME / IGTI Environment & Regulatory Affairs Committee. He also provided two chapters on a new 'Gas Turbine Emissions'​ book (Cambridge Univ. Press), published 16 technical papers, and helped organize many technical seminars on LNG systems, clean energy and cogeneration. Manfred holds a Bachelor in Mechanical engineering from Carleton University (1980).

Fields of expertise:

Specialization in industrial gas turbines, efficiency, air emissions, cogeneration & CHP

Provide training and technical advice on energy & environment

Balanced analysis of integrated system solutions to GHGs, air pollution and system reliability

System descriptions based on various GT combined cycle and cogen facility examples

Natural gas industry and compressor waste heat recovery applications.


Dieter Krapp


Dieter was an Executive Manager in large international Energy Companies with more than 30 years of broad experience. This experience includes managing large power generation assets, commodity sales & trading, structuring and negotiation of complex deals, M&A of power generation businesses and project management of large infrastructure projects in Europe, Asia and America.

In his career, he has successfully managed and restructured existing businesses and he has set up new start-ups and successfully positioned them in the market.

Since April 2016, Dieter has retired from OMV in Austria where I was responsible for their International Power Business and he is now focusing on part time assignments utilising my broad experience in Gas & Power Markets.

Fields of expertise:
