Hydrogen technology
Clean energy through modern H₂-combustion
With innovative combustion chamber technologies, Kawasaki enables the operation of gas turbines with hydrogen content ranging from 0 to 100 vol%. The systems offer high operational reliability, low CO₂ emissions and pave the way for future low-emission energy systems.
Low-emission combustion for natural gas with flexible H₂-content
DLE for natural gas
This DLE configuration offers stable, dry NOx reduction without water or steam injection. It is specially designed for natural gas operation, but supports hydrogen admixtures of up to 30 vol%. The technology was introduced at the Akashi plants in 2014 and has since proven itself in industrial applications. It is ideal for operators planning to take their first steps towards hydrogen integration without fundamentally modifying existing systems.
Hydrogen-compatible, stable DLE technology for 50 to 100 vol% H₂
DLE Micro-Mix
The Micro-Mix approach uses many small, fast-mixing combustion cells to enable particularly stable combustion at high hydrogen concentrations. NOx emissions are reduced purely dry, even at up to 100 vol% H₂. The technology was successfully used in the KOBE demonstration plant in 2020 and is considered an advanced solution for operators who want to switch to pure hydrogen operation at an early stage.
Robust burner type for 0 to 100 vol% H₂ with water- or steam-assisted NOx reduction
Diffusion flame
The diffusion flame is a proven combustion concept that processes flexible gas qualities and hydrogen contents of up to 100 vol%. NOx reduction is achieved using water- or steam-assisted processes and enables stable operation even with high load fluctuations. The technology was demonstrated in the KOBE demonstration plant in 2018 and is particularly suitable for applications where maximum fuel flexibility is a priority.
