Hitachi Zosen develops Japan's largest hydrogen generator

Tinuku - Hitachi Zosen Corp. has developed a solid polymer hydrogen generation system with a capacity of 200 normal cubic meters per hour, the largest in Japan, for enabling the storage of surplus power at megawatt-scale power generation facilities.

The company is set to start demonstration tests in the current fiscal year ending March 2019 toward a target release in the following fiscal year ending March 2020. Hitachi Zosen has engaged in the development of hydrogen generation systems consistently since 1974.

The company released the hydrogen generation system HYDROSPRING® in 2000 and went on to build a track record of delivering numerous units for industrial and R&D uses to government agencies, research institutes, and private companies.

Amid the rising use in recent years of electricity produced from renewable energy sources such as wind and sunlight, it developed the latest system in anticipation of a growing need for hydrogen and the future arrival of a “hydrogen-based society.”

Hydrogen generation systems are designed to perform electrolysis of water and produce high-purity hydrogen. The process of water electrolysis enables surplus power generated from renewable energy sources such as wind and sunlight to be stored as hydrogen.

The new system boasts the largest capacity in Japan, at 200 normal cubic meters per hour and also represents Japan’s first product compatible with megawatt-scale power conversion. Hitachi Zosen succeeded in expanding the system’s central component, the electrolytic cell, by combining its electrolysis and filter press technologies. The system is enclosed in a 40-foot container for mobility and low installation costs.

The company is concurrently developing a methanation process for reacting industrial emissions of carbon dioxide with hydrogen produced from renewable energy sources, with the aim of effectively reducing the use of fossil fuels and achieving carbon neutrality.

It will continue active efforts to promote the use of renewable energy that emits no greenhouse gases, and contribute to the Japanese government’s target of a 22%–24% share of renewable energy in 2030.
