Kawasaki Launches First Gas Engine for 30% Hydrogen Co-Combustion
Kawasaki Heavy Industries, Ltd. announced the commercialization of the Kawasaki Green Gas Engine, the first large-class gas engine capable of co-combustion with 30% hydrogen. This innovation, set to launch on September 30, 2025, marks a significant step towards cleaner energy and industrial hydrogen use, with enhanced energy efficiency and reduced NOx emissions.

Kawasaki Heavy Industries, Ltd. will commercialize the Kawasaki Green Gas Engine, a large-class gas engine capable of co-combustion with a mixture of natural gas and 30% hydrogen, starting September 30, 2025. This engine, tested at Kobe Works from October 2024 through rigorous assessments, offers improved energy efficiency and lower NOx emissions.
The engine can adjust the hydrogen co-combustion ratio in real-time and includes safety features like hydrogen leak detectors. Additionally, it supports retrofitting existing machines for this co-combustion technology.
