JERA and IHI to demo increased ammonia co-firing rate at Hekinan

Japan-headed energy utility JERA Co., Inc. (JERA) and compatriot IHI Corporation (IHI) have received notice of acceptance of their grant application, under the Green Innovation Fund program of the New Energy and Industrial Technology Development Organization (NEDO), to conduct a project to develop and demonstrate technology that increases the ammonia co-firing rate at coal-fired power plants.

With five units totaling 4.1 GW of power capacity, JERA Co., Inc (JERA) Hekinan Thermal Power Station in Hekinan City, Aichi Prefecture is Japan’s largest coal-fired power plant. Together with IHI Corporation (IHI) JERA is already conducting 20 percent ammonia co-firing tests at the 1 GW Unit 4 at the plant. A new NEDO project aims to demonstrate ammonia co-firing rates of 50 percent (photo courtesy JERA).

Ammonia enables efficient, low-cost transport and storage of hydrogen. In addition to this role as an energy carrier, it can also be used directly as a fuel in thermal power generation. As a fuel that does not emit carbon dioxide (CO2) when burned, ammonia is expected to offer great advantages in reducing greenhouse gas (GHG) emissions.

JERA and IHI are working under a NEDO grant program on a technology demonstration project that employs an ammonia co-firing rate of 20 percent at JERA’s Hekinan Thermal Power Station Unit 4.

Increase ammonia co-firing rate to 50 percent

The objective of this NEDO project is to develop a new ammonia co-firing burner and to install it at Hekinan Thermal Power Station Unit 4 or Unit 5 in order to raise the ammonia co-firing rate to at least 50 percent to further reduce CO2 emissions.

The term of the Project is approximately 8 years from FY 2021 to FY 2028. By FY 2024, JERA and IHI will develop a new burner capable of co-firing at least 50 percent ammonia and consider specifications for boilers and other equipment.

Based on the results, the two companies will decide whether to install the burners at the Hekinan Thermal Power Station.

If the burners are installed, plans call for co-firing with at least 50 percent ammonia at the actual power plant to begin by FY 2028.
