EBARA Receives Order for Liquid Hydrogen Booster Pumps and Cryogenic Hydrogen Return Gas Blower for Liquefied Hydrogen Supply Chain Commercialization Demonstration
- Providing a one-stop total solution for key rotating machinery to ensure stable operation of the LH2 Terminal -

EBARA CORPORATION (hereinafter "EBARA") and its group company, Ebara Elliott Energy have received an order from Kawasaki Heavy Industries, Ltd. (hereinafter "KHI") for liquefied hydrogen booster pumps and cryogenic hydrogen return gas blowers. KHI serves as the main contractor for the construction of a domestic liquefied hydrogen terminal (hereinafter "Kawasaki LH₂ Terminal") as part of the "Liquefied Hydrogen Supply Chain Commercialization Demonstration Project", which is led by Japan Suiso Energy, Ltd. and backed by the New Energy and Industrial Technology Development Organization (hereinafter "NEDO").
Through this order, EBARA will provide a total solution of essential equipment for the operation of the Kawasaki LH₂ Terminal.

Hydrogen is essential for achieving carbon neutrality as it emits no CO₂ during combustion. Japan is currently pursuing a large-scale commercial demonstration to reduce hydrogen supply costs in Japan by 2030, and the construction of Kawasaki LH₂ Terminal is progressing in Kawasaki City, Kanagawa Prefecture, as its base.

EBARA’s selection for this project is backed by its proven track record. In 2022, utilizing NEDO's subsidy program, EBARA successfully completed the world’s first liquified hydrogen test of a large-scale centrifugal liquid hydrogen pump at JAXA's Noshiro Rocket Testing Center.

Backed by high reliability and technological capabilities demonstrated in extreme environments at the space development level, EBARA will contribute to the success of this demonstration project.

The primary goal of this order is not just to provide individual equipment, but to establish a total solution by providing the "Liquid Hydrogen Booster Pump" and "Cryogenic Hydrogen Return Gas Blower" as a set. By providing essential primary rotating equipment for both liquid and gas for terminal operation in a one-stop manner, we will support the maintenance of the thermal balance and stable operation of the entire receiving terminal.

(i) Liquid Hydrogen Booster Pumps
These pumps increase the pressure of liquefied hydrogen discharged from storage tanks for stable supply to downstream equipment. They achieve the world’s highest pressure for this type of equipment. By limiting the number of units to four in series, EBARA contributes to cost reduction, simplified maintenance, and reduced risk for the plant.

(ii) Cryogenic Hydrogen Return Gas Blower
This compressor recovers and circulates low-pressure boil-off hydrogen gas generated within the facility, maintaining the pressure balance of the gas system between land and ship, including the cargo tank of the liquified hydrogen carrier. We will socially implement centrifugal blower technology in the cryogenic range, which was previously difficult, for the first time in the world*. By efficiently returning gas within the terminal to the ship, heat intrusion is minimized, and hydrogen loss is reduced.

EBARA is currently constructing the world's first full-scale commercial product testing and development center fully equipped with actual fluid testing facilities for liquefied hydrogen pumps in Futtsu City, Chiba Prefecture (scheduled for completion in summer 2026). Before delivery, EBARA will test the newly ordered products using liquified hydrogen at this center to verify the reproducibility of design head and flow rate characteristics, as well as stable continuous operation in cryogenic environments. Long-term reliability of equipment is essential for building a hydrogen supply chain. The products in this order play a particularly crucial role in "connecting hydrogen" at the liquified hydrogen receiving terminal. EBARA will lead the realization of a decarbonized society through the innovation of hydrogen-related technologies.

The EBARA Group, guided by its long‑term vision and medium‑term management plan, will provide essential solutions to global sustainability challenges to contribute to the creation of a sustainable society and to further enhance corporate value.
