The Okinawa Electric Power Company, Incorporated (OEPC), Tsubame BHB Co., Ltd. (Tsubame BHB), and Kawasaki Heavy Industries, Ltd. (Kawasaki) jointly applied for the FY2022 Okinawa Clean Energy Introduction Promotion Research Program, which was publicly solicited by Okinawa General Bureau, Cabinet Office of Japan, and our proposal, “Research Program on Onsite Production for Local Consumption of Clean Fuel Ammonia in Okinawa,” was accepted.

There is a strong need to reduce CO2 emissions from thermal power sources in Okinawa, and ammonia co-firing in coal-fired power plants is expected to be an effective means of decarbonization. In this research, we will investigate the feasibility and business viability of onsite production for local consumption of clean fuel ammonia, namely ammonia production (“Onsite Production”) utilizing electricity derived from renewable energy and ammonia co- firing in coal-fired power plants (“Local Consumption”).

Specifically, we will conduct and complete the following studies in fiscal 2022:

1. Research on the possibility of ammonia co-firing in Gushikawa Thermal Power Plant
   (Onsite Production for Local Consumption)
2. Research on ammonia production and supply (Onsite Production)
3. Research on modification of ammonia co-firing equipment in Gushikawa Thermal Power Plant

Through this research, OEPC, the largest electric utility in Okinawa, Tsubame BHB, which has ammonia catalyst technology and is developing a distributed ammonia production system, and Kawasaki, a comprehensive heavy industry manufacturer that supplies energy-related equipment, transportation equipment, etc. and is developing ammonia co-firing technology for coal-fired boilers, are committed to contributing to society by achieving a stable supply of energy and tackling global warming.
