GE Vernova Inc., based in Greenville, South Carolina, has successfully completed a validation test campaign for its advanced Dry Low NOx (DLN) hydrogen combustion technology for B- and E-class gas turbines. The tests showcased the system's ability to operate on natural gas and hydrogen blends, as well as on 100% hydrogen with dry emissions below 25ppm NOx. GE Vernova plans to make this new DLN system available for both new and existing B- and E-class gas turbines as early as 2026. This achievement highlights GE Vernova's leadership in gas turbine fuel flexibility and commitment to reducing carbon emissions. This technological advancement aims to enable the decarbonization of the B- and E-class gas turbine fleet worldwide. The company's Carbon Solution leader emphasized the engineering challenge of developing a combustion system that can safely burn 100% hydrogen due to its faster flame speed and risk of flashback. The prototype combustor demonstrated robust operation during the test campaign, showing low combustion dynamics and noise levels even when operating on pure hydrogen. The use of a micromixer-based fuel air pre-mixer, developed through extensive research starting in 2005, contributes to the prototype's capabilities. The new DLN combustor technology is expected to offer benefits such as increased efficiency, longer maintenance intervals, and reduced NOx emissions compared to existing systems. By eliminating the need for diluents like water, the H2 DLN combustor technology allows for more flexible operability on natural gas, hydrogen, or blends without compromising emissions abatement. The successful validation of this hydrogen combustion technology by GE Vernova signifies a significant step towards a more sustainable and efficient industrial gas turbine operation.
