Hyosung validates Hydrogen Generator Performance in Harsh Weather Conditions
10. July 2025Hyosung Heavy Industries has confirmed the year-round operational reliability of its 1MW hydrogen engine generator, following successful performance trials under extreme cold and heat. The unit, first installed at the Yongyeon plant of Hyosung Chemical in Ulsan in April last year, completed 1,400 hours of continuous operation during winter and had previously demonstrated consistent performance during high summer temperatures. It is the first commercialized hydrogen engine generator of its kind worldwide. Hydrogen systems related products usually require KGS factory registration in order to be approved for import and sale in Korea.
In addition to passing extreme weather trials, the generator has cleared safety reviews by the Korea Gas Safety Corporation and the Korea Electrical Safety Corporation, receiving authorization for commercial operation. Designed to operate solely on hydrogen, the system produces zero carbon emissions and offers flexible operation to complement intermittent renewable sources such as solar and wind. While most global competitors remain in testing stages, Hyosung is the only manufacturer to have completed real-world validation. The company aims to further develop its hydrogen combustion technology to strengthen its position in the eco-friendly energy market.
