IHI Group company, IHI Plant Services Corporation (Head Office: Koto-ku, Tokyo; President: Ryoji Aoki; hereinafter “IPC”), TAISEI Corporation (Head Office: Shinjuku-ku, Tokyo; President: Yoshiro Aikawa; hereinafter “TAISEI”), and Chubu Plant Service Co., Ltd. (Head Office: Atsuta-ku, Nagoya, Aichi; President: Akira Kuriyama; hereinafter “CPS”) have received an EPC (Engineering, Procurement and Construction) contract from JERA Co., Inc. (hereinafter “JERA”) for four fuel ammonia storage tanks (total capacity: 160,000 tons) and associated facilities, to enable commencement of commercial operation with large-volume ammonia combustion (20% of heating value) at the Hekinan Thermal Power Station. Construction work is currently in progress.
This project is one of the key initiatives under “JERA Zero CO₂ Emissions 2050.” Targeting the start of commercial operation of large-volume ammonia combustion (20% of heating value) at the Hekinan Thermal Power Station in fiscal 2029, construction work is steadily advancing. At present, the outer roofs of Tank No. 1 and Tank No. 2 have been raised using the air-raising method, completing the external appearance work.
Under this project, IPC is responsible for the overall design of the ammonia tanks and associated facilities, the procurement of equipment, electrical and instrumentation components, piping, and other materials, as well as the construction work for the ammonia storage tanks.
TAISEI is responsible for the foundations and dikes for the ammonia storage tanks, as well as the foundations and building works for the associated facilities.
CPS is responsible for the piping and rack design of the receiving facilities and for the mechanical, electrical, and instrumentation work of the associated facilities.
IPC will continue to contribute to the realization of a sustainable energy transition and a low‑carbon society through initiatives including the utilization of ammonia, leveraging its extensive track record and advanced technologies in LNG tank and terminal projects.
TAISEI is fully engaged in this project and will contribute to the realization of a decarbonized society through construction that pursues both safety and quality, under the Group philosophy of “Creating a Vibrant Environment for All Members of Society,” drawing on its long‑accumulated experience and advanced technical capabilities.
CPS has built trust by sincerely engaging with customers while working on the construction, operation, and maintenance of a wide range of plant facilities, and by continuously refining its technologies. Going forward, CPS will continue to contribute to the realization of a sustainable future society, together with its stakeholders, based on its human resources and technological capabilities.
