Tsubame BHB Recognized in the 2025 Global Cleantech 100

Tsubame BHB Co., Ltd., headquartered in Yokohama, Japan, has garnered significant recognition as one of the most innovative companies in the cleantech sector. Selected for the esteemed 2025 Global Cleantech 100 list, Tsubame BHB stands out due to its groundbreaking ammonia manufacturing technology that utilizes low-temperature and low-pressure processes powered by renewable energy.

Founded in 2017 and emerging from the Institute of Science Tokyo, Tsubame BHB was established with the vision of addressing pressing social issues, such as environmental challenges and food security. Under the leadership of CEO Koji Nakamura, the company focuses on the on-site production of ammonia at distributed plants. Their innovative techniques not only emphasize efficiency but also significantly lower the environmental impact associated with traditional ammonia production methods.

The company's unique use of electride catalyst technologies, developed by Professor Emeritus Hideo Hosono, enhances their ability to synthesize ammonia while minimizing energy consumption. This technology is not merely about improving manufacturing processes but also contributes to a broader goal: aiding in the transition towards a carbon-neutral society, as ammonia is increasingly seen as a promising solution for renewable energy and sustainable agriculture.

Achievements and Future Prospects

Last year, Tsubame BHB reached a significant milestone by attracting its first international investors and successfully raising approximately 5.3 billion yen through a Series C funding round. This financial boost is a testament to the growing interest in their innovative solutions. Furthermore, the company's selection as the sole Japanese participant in Germany's Startup Scale Program highlights its potential on a global stage.

Notably, Tsubame BHB's advancements have drawn attention from various international entities. Recently, CEO Martins Brinins of MP INDUSTRIES, an Estonian green hydrogen project developer, visited Tsubame BHB. Additionally, a delegation from PT PLN, Indonesia’s state-owned power company, toured Tsubame BHB's pilot plant, illustrating the escalating interest from diverse countries in their pioneering technologies.

In Japan, the company is set to commence operations this year at its inaugural commercial unit for ammonia production. This facility is designed for comprehensive verification tests focused on the manufacture and utilization of blue hydrogen and ammonia, paving the way for more sustainable industrial practices in the country.
