IHI Advances Development of Ammonia-Fueled Gas Turbines to Realize CO₂-Free Power Generation
IHI Corporation is actively advancing the development of ammonia-fueled gas turbines, a transformative technology with the potential to achieve CO2-free power generation. At its Aioi Works, IHI is conducting durability tests on gas turbines utilizing clean ammonia. The decarbonization value generated through the use of clean ammonia will be provided to the 2025 Osaka-Kansai Expo, contributing towards the realization of a carbon neutral event.
In 2022, IHI, in collaboration with Tohoku University and the National Institute of Advanced Industrial Science and Technology (AIST), successfully developed and demonstrated CO2-free power generation using 100% liquid ammonia in gas turbine facilities. This achievement was realized under the "Green Innovation Fund Project: Fuel Ammonia Supply Chain Development," led by the New Energy and Industrial Technology Development Organization (NEDO).
Towards societal implementation of this innovative technology IHI commenced durability testing, simulating actual operational conditions, in July 2024 at its Aioi Works and have confirmed the suppression of nitrous oxide (N2O) and nitrogen oxide (NOx) emissions as planned.
The electricity generated during these tests is being utilized within Aioi Works facility, with the decarbonization value derived by using clean fuel ammonia to be provided to the 2025 Osaka-Kansai Expo.
