Fuel ammonia production and utilization technology
We have been focusing on the utilization of ammonia to provide sustainable solutions to energy problems. Ammonia is easy to transport and store and does not emit CO₂ when burned. These characteristics allow ammonia to be an attractive alternative to fossil fuels. As ammonia can serve as a hydrogen carrier as well as a fuel, it is expected to be versatile in the energy field.
Ammonia gas turbines
We have developed an ammonia-fired combustor for the IHI-manufactured IM270 gas turbine with rated output of 2 MW and successfully demonstrated liquid 100% ammonia single firing. While conducting a long-term durability test at the Aioi Works, we are on the way to technology development for larger gas turbines.

Ammonia boilers
To achieve decarbonization in the energy field, we are working on ammonia substitution for existing large-scale coal-fired power generation boilers. In 2024, we completed the large-scale demonstration test using IHI-developed ammonia burners at the Hekinan Thermal Power Station of JERA Co., Inc. We work on technology development with the goal of higher substitution rates.

Ammonia-fueled engines
Aiming to achieve zero emissions of CO₂ from vessels, we are developing marine engines fueled by ammonia. Ammonia-fueled marine engines make it possible to construct an ammonia value chain, which is estimated to require the high demand for marine transport, without increasing CO₂ emissions.
