Tsubame BHB Co., Ltd. (Head Office: Yokohama, Kanagawa Pref., Representative Director and CEO: Koji Nakamura; hereafter“Tsubame BHB”), which aims to implement and commercialize distributed ammonia production plants, has signed a memorandum of understanding (MOU) with Mizuho Bank, Ltd. for collaboration and cooperation on the business development of green hydrogen and ammonia in African economies. Through this MOU, we will leverage Mizuho Bank’s network across various African countries to promote the commercialization of green hydrogen and ammonia businesses based on our technology.

Many African countries rely on imports for fertilizer and energy, making them vulnerable to volatility in international markets. With small-scale distributed ammonia production plants, Tsubame BHB aims to launch local production and consumption businesses model for green hydrogen, ammonia, and low-carbon fertilizer by utilizing locally available water, air, and renewable energy sources. This initiative will contribute to food security in African nations and global decarbonization efforts.

The signing ceremony for this MOU was held at the Yokohama Bankers Association on August 21, in conjunction with the 9th Tokyo International Conference on African Development (TICAD9) held in Yokohama from August 20 to 22, 2025.
