Sale of 1.4MW Electrolyser to Sumitomo Corporation

First MW scale electrolyser system ITM Power will deploy in Japan

ITM Power (AIM: ITM), the energy storage and clean fuel company, is pleased to announce the sale of a 1.4MW electrolyser to Sumitomo Corporation ("Sumitomo"). The deployment will be used as an important reference plant for further sales in Japan through our partnership with Sumitomo.

This will be the first MW scale electrolyser system ITM Power has deployed in Japan. The HGas2SP product will undergo modification to ensure hydrogen supply pressure is below 10 bar in order to comply with Japan's High Pressure Gas Safety Act. ITM Power and Sumitomo are continuing their collaboration in the areas of business development, local compliance and after sale support to ensure a comprehensive green hydrogen offering in Japan.

Mr Hajime Mori, GM Energy Division of Sumitomo Corporation, said: "This is a significant step forward for the Japanese electrolyser market. Sumitomo is participating in several green hydrogen projects in Japan and ITM Power's technology will contribute in scaling up and cost down of these projects in near future."

Dr Graham Cooley, CEO of ITM Power, said: "I am delighted to be able to report tangible progress in Japan. Our partner Sumitomo continues to bring opportunities to ITM Power for evaluation and we are both working to identify synergies within the wider Sumitomo Corporation. This project is an important reference deployment and we look forward to the execution phase of the project and further progress in the important Japanese market."
