Emissions and Performance Implications of Hydrogen Fuel in Heavy Duty Gas Turbines

Decarbonized gas turbines can serve a significant role in achieving goals for climate change mitigation. Recognizing that hydrogen can be a pathway for achieving zero carbon emissions, original equipment manufacturers (OEMs) are focused on enhancing the capability to operate gas turbines on fuels with high hydrogen content.

This paper surveys recent technology developments with respect to hydrogen use in heavy-duty (i.e., utility-scale) gas turbines and identifies challenges, potential solutions, and potential pathways for OEMs to achieve 100% hydrogen capability, with special attention to NOx emissions and performance.
