Kawasaki Commences Sales of Hydrogen Liquefier ～ Performance and reliability demonstrated by long-term continuous operation for over 3,000 hours ～
Jun. 10, 2020
Tokyo, June 10, 2020 - Kawasaki Heavy Industries, Ltd. announced today that it started selling of the hydrogen liquefier which was the first developed by made-in-Japan technologies with industry-leading liquefaction efficiency.
Hydrogen is a clean energy that does not generate greenhouse gases when used as a fuel for power generation or fuel cell vehicles etc., and is expected to be used about 300,000 tons per year※1 around 2030. Focusing on the property of hydrogen, which becomes 1/800 in volume by liquefying at minus 253°C, Kawasaki engaged in research and development of liquefaction technology.
The hydrogen liquefier has demonstrated its performance and reliability through continuous demonstration operation for over 3,000 hours and various functional tests carried out until this spring.
The main features are as follows;
|･||Capability of producing 5 tons of liquefied hydrogen per day (equivalent to 1,000 FCVs’ fuel)|
|･||Industry-leading liquefaction efficiency※2, of which key factors are a heat exchange cycle and liquefaction process developed by ourselves utilizing our technology cultivated in the development of high-speed rotating machines such as gas turbines for power generation and jet engines for aircraft|
|･||Production of high purity hydrogen at 99.999%※3 and realization of easy maintenance, which have been realized since inclusion of impurities are eliminated in the hydrogen liquefaction process|
|･||Compact layout due to the vertical structure of the liquefier (earthquake-resistant design)|
|･||Prompt start of liquefaction within 24 hours※4 after start-up of the plant|
In addition, Kawasaki has many related technologies such as storage tanks and transport containers with high heat insulation performance for storing liquefied hydrogen. It enables to provide engineering and procurement for not only hydrogen liquefier but also hydrogen liquefaction plant. Furthermore, Kawasaki plans to expand the line-up of hydrogen liquefier according to the spread of market demand of hydrogen.
By promoting the further spread of hydrogen energy while helping to eliminate CO2 emissions in pursuit of sustainable development goals (SDGs), Kawasaki hopes to contribute to a future characterized by enriched, prosperous lifestyles and a healthy global environment.
