Sumitomo starts hydrogen demonstration experiment using megawatt-class water electrolyser
Tokyo-based Sumitomo Corporation and Tokyo Gas Co, Ltd. have agreed to conduct a joint hydrogen utilisation demonstration experiment at the Tokyo Gas Yokohama Techno Station using a megawatt-class polymer electrolyte membrane water electrolyser developed by UK-headquartered ITM Power.
In this demonstration, Sumitomo will be verifying the operation of ITM Power’s large water electrolyser. This is the first operational verification to be carried out in Japan on a foreign-made large water electrolyser. Sumitomo Corporation plans to deliver a 2.0 MW-class water electrolyser, with its hydrogen discharge pressure adjusted from the product’s standard specification of 2 MPa to less than 1 MPa to comply with Japanese domestic regulations, to Tokyo Gas Yokohama Techno Station in June 2022 and start a joint demonstration of the electrolyser.
Tokyo Gas will install the water electrolyser and operate it under various operating conditions to understand the performance of the latest-generation water electrolysers, and to accumulate know-how on the introduction of large water electrolysers, including on equipment operation and construction of related facilities.
The hydrogen produced will be used for the research and development of hydrogen utilisation at Tokyo Gas Yokohama Techno Station with the aim of achieving decarbonisation. The results from this demonstration will be shared by the two companies and utilised for future business development.
