JERA, a Japanese power generator, announced the successful conclusion of a three-month trial at its Hekinan Thermal Power Station in Central Japan. In this trial, they co-fired ammonia and coal at a 20% ratio. The results were positive.
In collaboration with IHI Corporation and the New Energy and Industrial Technology Development Organization (NEDO), JERA has been engaged in the NEDO-subsidized project titled “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.”
The trial included the world’s first demonstration of large-volume fuel ammonia substitution (20% of heating value) at a large-scale coal-fired thermal power plant.
JERA reported positive results, noting that nitrogen oxide levels were no higher than when coal was fired alone. Additionally, sulfur oxides were reduced by 20%, and the generation of nitrous dioxide, a potent greenhouse gas, was below the detection threshold.

The company, jointly owned by Tokyo Electric Power and Chubu Electric Power, confirmed that the plant’s operability was comparable to that when burning coal alone.
Based on the study results, the company will start construction in July for commercial operation at Hekinan Power Station using ammonia fuel substitution large volume.
Additionally, JERA said it will carefully assess how the recent tests affected the boiler and related equipment. They aim to develop technologies to use ammonia as a common fuel in thermal power plants by March 2025.
By developing these technologies, JERA plans to provide a clean energy platform that mixes renewable energy with low-carbon thermal power, helping support the growth and development of Asia and the world.
