Jera, IHI plan ammonia co-firing plant in Japan
Japan's Jera and IHI Corp have had a grant application accepted for a programme to co-fire ammonia with coal in thermal power generation, they said on May 24.
The demonstration project will be conducted under the Japanese state-run New Energy and Industrial Technology Development Organisation’s “Development of Technologies for Carbon Recycling and Next-Generation Thermal Power Generation / Research, Development and Demonstration of Technologies for Ammonia Co-Firing Thermal Power Generation" programme.

“Looking to reduce future environmental impact, the demonstration project aims to establish ammonia co-firing technology by co-firing coal and ammonia at a large-scale commercial coal-fired power plant and evaluating both boiler heat absorption and environmental impact characteristics such as exhaust gases,” the companies said. The project will run for approximately four years from June 2021 to March 2025.
In the project, the companies plan to demonstrate an ammonia co-firing rate of 20% at Unit 4 of Jera's Hekinan thermal power station in Aichi prefecture in 2024. Jera will procure ammonia and build related facilities such as the storage tank and vaporiser, while IHI will develop the burners.
In order to ensure the reliability of high-volume ammonia co-firing, the two companies plan to verify the necessary parameters for developing the demonstration burners by conducting small-scale ammonia co-firing tests using burners of different materials at Unit 5 of the Hekinan station from August to December 2021.
