Mitsui & Co., Ltd. together with Hokkaido Electric Power Co., Inc., Mitsubishi UBE Cement Co., Ltd., and Tosoh Corporation announced on December 19, 2025, that they received approval from Japan's Minister of Economy, Trade, and Industry (METI) and the Minister of Land, Infrastructure, Transport, and Tourism (MLIT) for certification under a price gap support system within the Hydrogen Society Promotion Act.

Price Gap Support System Details

The Support for the Price Gap system, implemented by METI's Agency for Natural Resources and Energy, aims to accelerate the supply and utilization of low-carbon hydrogen and derivatives. Over a 15-year period, the system provides support focused on the price gap between existing raw materials and fossil fuels, and on low-carbon hydrogen and its derivatives.

Based on the business plans certified by METI and MLIT, Mitsui & Co. and the three other companies aim to establish a low-carbon ammonia supply chain for Japan by fiscal year 2030.

Low-Carbon Ammonia Production and Supply Chain

Under the certified plan, Mitsui will purchase a portion of the production from Blue Point, a low-carbon ammonia manufacturing project in Louisiana, USA, for which Mitsui is participating as an investor. Mitsui will supply a total of 280,000 tons of this low-carbon ammonia annually to Hokkaido Electric Power Co., Inc., Mitsubishi UBE Cement Co., Ltd., Tosoh Corporation, and other customers.

Low-carbon ammonia is ammonia produced with significantly lower CO2 emissions than conventional manufacturing processes. It is expected not only to decarbonize the value chain for its traditional uses in fertilizers and chemical products, but also to serve as a clean fuel that emits no CO2 during combustion.

Each customer will utilize the low-carbon ammonia as fuel or raw material, thereby reducing environmental impact compared to conventional methods. In Japan, which has enacted a Hydrogen Society Promotion Act, low-carbon ammonia is being explored as one form of low-carbon hydrogen for utilization as a fuel and as a chemical feedstock.

Commercial Implementation and Industry Collaboration

This project marks Japan's first large-scale commercial import of low-carbon ammonia. Mitsui, with its extensive experience in manufacturing, transporting, and importing ammonia and energy products, will collaborate with multiple end-users across industries including power generation, ceramics, and chemicals to achieve early societal implementation, expand the use of low-carbon ammonia, and establish a stable value chain.

The project aligns with Mitsui's corporate mission to “Build brighter futures, everywhere” and contributes to gaining the trust and expectations of stakeholders to realize a better tomorrow for the Earth and for people around the world. The company has identified six material issues for Mitsui's sustainable growth, and this particular project is anticipated to contribute especially to the realization of “Establish a foundation for sustainable and stable supply.”
