Panel Sessions

The following panel sessions have been organized by the ASME IGTI committee and track chairs. The panelists are industry leaders who will present information as it relates to the respective committee or track. These panel sessions are available to all Turbo Expo virtual conference attendees. Register to attend these highly informative sessions and support your peers! The panel sessions will be presented "live", therefore, a video on-demand will not be available pre-conference or post-conference.

Gas turbines (GT) could be ready for wide-scale commercial operation with low-carbon fuels within the next 10 years, but broad deployment will likely depend on successful, near-term field demonstrations.

The degree to which the existing GT power generation fleet ultimately transitions to blended fuels will depend upon equipment/hardware capability, policy changes, financial incentives, and the availability of sufficient quantities of these alternative fuels at an acceptable price.

Technical hurdles must be addressed to allow for safe and reliable operation of combustion assets with blended fuels. Many lab- and pilot-scale studies have previously focused on combustion characteristics and results suggest fuel blending could be accomplished with modifications to existing equipment. However, full-scale testing is needed to ensure that operation behavior is understood over the range of conditions that these machines, especially F-class and above GTs, are expected to operate.

The GT owners and operators are faced with many challenging tactical and strategic decisions with their existing GT fleet as well as needs and requirements in the long-term perspective for the next generation fleet. The objective of this session is to highlight operational and research needs both in the short-term and long-term as guidance for the equipment suppliers and the research community.

The Panelists will address these issues over two time periods:

1. The GT user communities needs in the next 10 years:
Gas turbines development and retrofit needs in the energy transition (up to approx. 2030)

  • Introduction by Rob Steele, EPRI
  • Panelists: Tomas Alvarez Tejedor, ENEL, Aaron Guthrey, LADWP, Jay Lim, LADWP, Lawrence Sparks, TVA

2. The GT user communities needs for a continued transition to low carbon/carbon-neutral society: Most promising R&D opportunities and key research fields (approx. 2030-2050)

  • Introduction by Christer Björkqvist, ETN Global
  • Panelists: Olaf Brekke, Equinor, Sigrid Gijbels, Engie, Albannie Cagnac, EDF


  • Jeremee Wetherby, GE Gas Power
  • Mauro Moretto, Ansaldo Energia
  • Frida Björneld, Siemens Energy
  • Koichi Ishizaka, MHI

Panelists will provide a 15-minute presentation followed by 30 minutes of live Q&A. Presentations will provide an overview of the company's vision for gas turbine technology in the context of current and future markets and technology requirements to succeed in these future markets.

This panel session focuses on novel experimentation and accelerated methods for the qualification of alloys. Integrated computational materials science and engineering (IMECE) and advanced manufacturing techniques have enabled both the rapid identification of candidate material systems and the rapid manufacture and thermomechanical processing of candidate alloys. These "designer" alloys are calculated to exceed the performance requirements of existing materials; however, there is a need to replace calculations with a "physical qualification" of candidate alloys. There is a need for rapid, miniaturized, parallelized, and automated material qualification techniques. Numerous new test methods are in development to deal with these challenges. In this panel, panelists shall discuss the state-of-the-art techniques ongoing within there organizations and the wider range of techniques in development around the world.
