NEDO:World’s First Successful Technology Verification of 100% Hydrogen-fueled Gas Turbine Operation with Dry Low NOx Combustion Technology
The New Energy and Industrial Technology Development Organization (NEDO),
Kawasaki Heavy Industries, Ltd.
Obayashi Corporation
announced successful technology verification, for the first time worldwide, of 100% hydrogen-fueled gas turbine operation with dry low NOx (nitrogen oxides) combustion technology.
The key technology of this gas turbine
is newly developed combustor component by Kawasaki, applying micro-mix combustion principle. And operation test
was started in early May as part of the National program “Technology Development Project for Building a Hydrogen-besed Society”.
Dry low NOx combustion technology
improves the electrical efficiency comparing to the conventional combustion method: water injection, as well as reduction of NOx emissions.
1. Overview
Technology verification tests, supplying
electricity and heat generated by the hydrogen-fueled gas turbine cogeneration system to nearby facilities in Kobe City’s Port Island, are planned to start in this fall.
And hydrogen-based power generation operation stability with dry lowNOx combustion technology, electrical efficiency improvement, and environmental load reduction effects will be investigated.
