Renewable, carbon-free power generation continues its journey in transforming and reshaping the fundamental operational dynamics of the today’s utility grid. However, the inherent volatility and intermittency of renewable power, namely, when the wind doesn’t blow and the sun isn’t shining, necessitates a responsive, dispatchable, flexible and complimentary power generation and energy storage solution that will cost effectively counter load swings in a reliable, secure manner.

CO2 emissions from natural gas-fired turbines, while significantly less intense than those from coal-fired power generation, are still substantial, so for these energy conversion devices to remain a viable part of the future generation mix, their carbon footprint must be significantly reduced to the point of eliminating them as a source.

This panel session will focus on the technical challenges with using hydrogen and potentially ammonia as a fuel for gas turbines while maintaining reasonable exhaust NOx emissions, operational flexibility and overall life cycle costs. Because hydrogen is more reactive than natural gas, today's gas turbine combustion systems, whether in new unit applications or as retrofits to the existing installed fleet, are challenged to handle meaningful variable mixtures of these fuels, which should be an important design consideration. A current status of the main technology developers of gas turbine hydrogen fuel-flex combustors and the challenges to develop 100% H2-capable systems will be highlighted, including technology development roadmaps and timelines towards 100% hydrogen fuel use capability.
