High-pressure hydrogen regulator for a new fuel cell city bus

Tokyo, February 21, 2024 ―Kawasaki Heavy Industries, Ltd. announced today that it has been adopted for high-pressure hydrogen regulators to be used in a new fuel cell city bus by one of the world’s largest commercial vehicle manufacturers in Germany.

The product plays the important role of reducing the pressure of hydrogen gas, which is supplied from a hydrogen tank installed on the fuel cell bus at a high pressure of approximately 350 atmospheres, until the pressure reaches a level where the gas can be used in the fuel cell stack.1 This regulator contributes to space savings and increased range by improving fuel efficiency. This is achieved by enabling efficient reduction of hydrogen gas pressure using high-precision gas control technology, and by stabilizing hydrogen gas pressure during power generation. At the same time, it offers superior reliability, having cleared durability tests that suggest a life of 20 years.

This high-pressure hydrogen regulator is the fruit of Kawasaki’s technological capabilities and experience built up over the years on hydrogen products. Kawasaki successfully manufactured and supplied this product to a client for a mass production fuel cell vehicle in 2018. Based on the client’s high evaluation of Kawasaki’s contributions to the fuel cell vehicle, reliability and overall high-level technological capabilities at the time, Kawasaki has earned the client’s trust and confidence, which led to the recent adoption for use in the new fuel cell city bus.

Kawasaki is honored to contribute to the client and is pleased to see that our hydrogen product continues to expand. In Kawasaki’s Group Vision 2030, which describes the company’s future vision for 2030, “Energy and Environmental Solutions” has been specified as one of the areas it will focus its efforts on. The company will continue to contribute to global decarbonization efforts through the promotion and use of hydrogen as a clean energy source.
