Kawasaki Heavy Industries, Ltd. announced that it would start sales of large class gas engines capable of hydrogen 30％ co-firing for the first time in the world, starting from the same day.
Since October 2024, at our Kobe Works, we have been conducting operational verification of a gas engine power generation system (8MW class), that can co-fire natural gas mixed with up to 30% hydrogen (by volume) as fuel, focusing on hydrogen supply, maintainability, and other operational factors. The verification was completed in September 2025.
The 'Kawasaki Green Gas Engine' has received over 240 orders since its first order in 2011 as a high-efficiency gas engine using natural gas in 5-8MW class. Based on such technology and experience, this product is a hydrogen-ready model that can burn a mixture of up to 30% (by volume) hydrogen with natural gas or city gas, making it adaptable to decarbonization and energy transition.
As a transition technology towards realizing a carbon-neutral society, this product enables practical and sustainable decarbonization as a distributed power source by increasing the hydrogen utilization ratio while leveraging existing facilities and infrastructure.
