Tsubame BHB procures 5.3 billion yen through Series C

First participation by a foreign investor brings green ammonia production to the world

YOKOHAMA, Japan, Feb. 21, 2024 /PRNewswire/ -- Tsubame BHB Co., Ltd. (Head Office: Yokohama, Kanagawa Pref.; Representative Director and CEO: Koji Nakamura), which strives for the social implementation and commercialization of small, distributed ammonia production plants, has announced that it has undertaken capital procurement on a total scale of approximately 5.3 billion yen in a Series C round of financing through third-party allocation of shares to both new and existing investors worldwide.

In the second round^*1 of this Series C funding, capital procurement was undertaken with Heraeus Beteiligungsverwaltungsgesellschaft mbH (Head Office: Germany; "Heraeus") as the first overseas investor receiving shares, and with Yokogawa Electric Corporation and Energy & Environment Investment, Inc. as new investors receiving shares in Japan. This round of funding resulted in a cumulative capital procurement amount of 7.6 billion yen for Tsubame BHB Co., Ltd.

*1 The first round of funding was procured through convertible equity (CE) subscription warrants in July 2022

Tsubame BHB was established in April 2017 to achieve the social implementation and commercialization of on-site ammonia production at small, distributed ammonia production plants capable of synthesizing ammonia at low temperatures and low pressures, using the world's first electride catalyst method. The Heraeus Group, based in Hanau, Germany, is a major family-owned technology company with multifaceted global operations. It has approximately 17,200 employees in 40 countries around the world, and boasts a diverse business portfolio that includes fields such as metals and recycling, healthcare, semiconductors and electronics, and industrials. With Heraeus participating as the first overseas investor, Tsubame BHB will develop the ammonia business and strengthen supply chains with a particular focus on Europe.

The EU decided to introduce a Carbon Border Adjustment Mechanism (CBAM) for the first time in the world, requiring businesses to report on carbon emissions from October 2023. Actual taxation based on these emission volumes is scheduled to begin from 2026. On February 6 of this year, the European Commission announced that CO2 emissions in the EU should be cut to 90% compared to 1990 levels by 2040. Given the need for CO2 reductions and actions to combat climate change in the EU, there is a growing demand for green ammonia, particularly in the chemical, transportation, and agricultural industries.

The synthetic ammonia catalysts offered by Tsubame BHB, which are produced at low temperatures and low pressures using electride catalysts, can be manufactured at small ammonia production plants, and so can be produced and consumed locally. Transport and storage processes are reduced in comparison to current procurement methods involving high-volume production at petrochemical complexes, enabling a substantial reduction in CO2 emissions.

In collaboration with Heraeus, which has a history spanning close to 400 years, Tsubame BHB uses an electride catalyst technology developed in Japan to promote the localization of ammonia production at small, distributed on-site ammonia plants, and the manufacture of green ammonia and hydrogen ammonia using renewable energy.

• Current status of business/development

The first installation project in Japan, ordered in December 2022, is currently moving ahead steadily with plans for the start of production in August 2025. Detailed design and procurement are already complete. Receipt testing at the main device plant will begin from April 2024, and deliveries to the construction site are scheduled to begin in May.

Tsubame BHB has an R&D Center at the Tokyo Institute of Technology, where R&D targeting catalysts is conducted in collaboration with about 30 researchers. Verification tests of catalysts developed at a pilot plant in Ajinomoto Co., Inc.'s Kawasaki factory began in 2019, and over the course of four years, these tests confirmed that Tsubame BHB's technologies had transcended the laboratory level, meeting requirements for commercialization. Catalysts suited to on-site ammonia plants are at the commercialization stage. Tests confirmed that formation and increased production on a scale of more than 100,000x could be achieved, and that after four years of uninterrupted catalyst performance operations, there was absolutely no decline in performance.

Applying government subsidies, commercialization of next-generation catalysts is expected to be achieved in a short time, with further cost reductions scheduled for the future.

• Tsubame BHB receives orders for basic design in Japan and overseas

In December 2023, Tsubame BHB received its first order for the basic design of an overseas unit in Southeast Asia. Production of green ammonia is expected to begin from FY2026. A project order was also received for basic design on a second unit in Japan, with ammonia production similarly scheduled to begin during FY2026.

In December 2023, a letter of intent (LOI) was signed between Agri Laos Co., Ltd. ("Agri Laos"), a business partner in Laos, and the Laotian State Enterprise for Agriculture Service ("SAS") regarding an offtake agreement for low-carbon fertilizers. Tsubame BHB and Agri Laos have formed a special purpose company (SPC) to promote the development of projects involving the manufacture of green hydrogen and ammonia and low carbon fertilizers using renewable energy and hydroelectric power in Laos. SAS plans to purchase the low-carbon fertilizers produced on this project for sales in Laos and other countries.

Tsubame BHB has received an increasing number of inquiries from overseas companies, and has initiated projects targeting the on-site production of ammonia at small-scale plants in collaboration with companies in various countries in North and South America, Southeast Asia, and Africa.

• Future developments

The capital procured through this round of financing will go toward R&D targeting further cost reductions at small, distributed ammonia plants and the commercialization of medium-scale plants, as well as technical development costs for next-generation catalysts with a view toward large-scale plants and recruiting/labor costs, which are particularly important in the context of business operations. In this way, Tsubame BHB will contribute to the commercialization of small-scale ammonia production plants originating in Japan.

• Investors in this round

Along with Tsubame BHB's first overseas investor, Heraeus Beteiligungsverwaltungsgesellschaft mbH, investors participating in this round of financing will include the following companies:

Energy & Environment Investment, Inc.

"Amid an urgent demand for decarbonization in various fields, ammonia is expected to be used not only as a hydrogen carrier, but also as a clean fuel in its own right, with applications for single fuel ammonia combustion in large-scale transportation (e.g., ships and aircraft) as well as thermal power generation. It has the potential to be a key driver in decarbonization, but in order to achieve this goal, renewable energy must be used in the manufacturing process as well "said by Member of the Board and Partner: Kenyu Hosoya. "Using Tsubame BHB's technologies, ammonia can be manufactured at low temperatures and low pressures, enabling small, distributed manufacturing facilities. In this way, in addition to supporting the worldwide use of green ammonia manufactured using renewable energy, these technologies are expected to contribute to decarbonization as well."
