126005 - Review of the Impact of Hydrogen-Containing Fuels on Gas Turbine Hot-Section Materials 

In an effort to achieve worldwide decarbonization goals, a range of low-carbon fuels are being proposed for use in power-generation gas turbine engines. One promising class of carbon-free fuels is hydrogen-containing fuels, such as hydrogen and ammonia, which do not produce any CO₂ upon combustion. While the use cases for these fuels differ, each has the potential to reduce the carbon intensity of power generation as compared to the current use of natural gas or other fossil fuels. Many studies have considered the impact that these fuels will have on combustion stability and emissions, as well as other practical considerations like balance of plant. However, potential challenges for the material systems in these engines, particularly high-temperature metal alloys and coatings, have not been as extensively considered in preparation for the introduction of these fuels. In this paper, we provide an overview of the potential materials-related issues associated with implementation of these hydrogen-containing fuels, with a focus on the hot section components. We also provide a review of the current literature related to the impact of hydrogen-containing fuel combustion on gas turbine materials. Based on the available literature, we outline potential avenues for research and development to facilitate the safe and reliable introduction of these fuels in power-generation gas turbine engines.
