Kawasaki begins construction of a demonstration facility for hydrogen liquefication plants

The development and demonstration of this machine are being carried out as part of a Green Innovation Fund project titled ‘Development of large-scale high-efficiency machineries for hydrogen liquefiers’, sponsored by the New Energy and Industrial Technology Development Organization (NEDO). The manufacturing of the demonstration machine has been completed, and construction of the demonstration facility has begun.

Construction of the demonstration facility will continue forward toward completion in November 2025, followed by one year of operational testing.

This machine is responsible for the process of boosting the pressure of refrigerant hydrogen gas, which is used to cool the feed hydrogen gas that serves as the raw material for liquefied hydrogen. Improving the efficiency of the liquefaction process is essential for reducing hydrogen supply costs. Kawasaki is developing a large scale centrifugal hydrogen compressor designed for 100% pure hydrogen to enhance liquefaction efficiency.

This machine achieves high efficiency by incorporating technological developments such as new impellers, the machine’s key component, and the adoption of a centrifugal design capable of handling large flow rates.

The knowledge and data gained through the development of this machine will also be applied to the development of centrifugal hydrogen compressors for hydrogen supply pipelines, where demand is expected to increase in line with the expansion of hydrogen energy.
