Tsubame BHB and INPEX Collaborate on Innovative Ammonia Synthesis Trial

The Beginning of a Sustainable Energy Era with Tsubame BHB

Tsubame BHB Co., Ltd., based in Yokohama, Japan, is making significant strides in the ammonia synthesis sector. On January 6, 2026, the company announced the commencement of trial operations at their ammonia synthesis facilities located within INPEX's Kashiwazaki Hydrogen Park. This initiative marks a notable advancement in the field of sustainable energy production, particularly in ammonia, which plays a crucial role in energy transition approaches.

Innovative Synthesis Technology

Tsubame BHB is leveraging its proprietary electride catalyst technology, which allows for ammonia production at lower temperatures and pressures than traditional methods. This approach not only enhances efficiency but also aligns with global goals for reduced greenhouse gas emissions. The new facilities exhibit an impressive production capacity of 500 tons of ammonia annually and boast a compact design that facilitates on-site installation.

The technology utilized by Tsubame BHB represents the future of ammonia synthesis, perfect for local production aligned with immediate demand. This operation is part of a broader initiative focusing on blue hydrogen, derived from Japanese natural gas, positioning Tsubame BHB at the forefront of innovation in this critical area of renewable energy.

Safety and Sustainability

The ammonia synthesis facilities have garnered praise from INPEX due to their superior safety protocols and the ability to significantly lower the required energy for gas pressurization. This attention to safety and innovation contributes to the project’s viability and its potential to serve as a model for other regions looking to adopt similar technologies.

Tsubame BHB’s CEO, Koji Nakamura, has expressed pride in achieving this milestone, calling it a meaningful project for Japan. He envisions this initiative as a gateway to collecting essential data that can enhance ammonia production's competitiveness. The company is also considering expanding its operational capabilities, with models that could produce up to 5,000 tons per year already in planning stages.

Future Prospects

The future looks bright for Tsubame BHB, not just within Japan but globally as well. The company is actively engaging in discussions about introducing additional production units in regions such as Brazil, Africa, and India. By promoting on-site ammonia production, Tsubame BHB aims to streamline operations, reducing transportation and storage costs while contributing to diminished greenhouse gas emissions.

The emphasis on 'local production, local consumption' is more than just a slogan; it's a strategic imperative that can redefine energy and chemical infrastructures worldwide.

Recognizing Excellence

Following its outstanding achievements, Tsubame BHB has received international recognition as a member of the "2025 Global Cleantech 100" list, celebrating promising global cleantech companies. This accolade underscores the company's innovative approach to ammonia synthesis, particularly as it aligns with global decarbonization goals. Additionally, Tsubame BHB showcased its technologies at COP28 and is set to exhibit again at COP30, further solidifying its role as a contributor to worldwide climate change solutions.

Conclusion

As Tsubame BHB aims to establish a new industry centered around distributed ammonia production plants, it remains committed to the societal vision of resolving critical issues associated with food and environmental sustainability. With ongoing projects and potential expansions in sight, Tsubame BHB is not just participating in the future of energy production; it is leading the charge towards a more sustainable world.
