Hydrogen Combustor

Our hydrogen combustion technology effectively addresses key challenges: the risk of equipment damage from flashback phenomena and vibration caused by rapid flame propagation during hydrogen combustion, and increased nitrogen oxide(NOx) emissions.
Additionally, it can be applied to major OEM gas turbines, enabling rapid conversion to hydrogen power generation with minimal modifications to existing power facilities.

Achievement

Successful Development and Demonstration of Utility-Scale Hydrogen Turbine

With Korea's first successful demonstration of 100% hydrogen combustion in an 80 MW-class gas turbine, we are at the forefront of utility-scale hydrogen turbine development. Additionally, we are developing hydrogen co-firing power generating technology for Korea's most extensively installed F-class gas turbines.

80 MW-class Hydrogen Co-firing and Full-firing Power Generation Achievements

April 2023 : Successful demonstration of 60% hydrogen co-firing ratio at 100% load
November 2023 : Successful demonstration of hydrogen full-firing at no load
May 2024 : Successful DLR test under 100% load conditions with hydrogen full-firing
