Tokyo Facility Which Converts Sewage Into Hydrogen Completes Construction

Last Updated on 08th January 2024

Ways2H, a Renewable hydrogen systems manufacturer, and its shareholder and technical partner Japan Blue Energy Co. on 30th March announced the completion of a facility in Tokyo which is capable of converting sewage sludge into renewable hydrogen for fuel cell mobility and power generation. With construction, led by Toda Corporation, now complete, the companies plan to start ramping up operations by mid-2021.


The technology of converting waste into hydrogen used by the facility was developed and owned by Japan Blue Energy Co Ltd. Besides Ways2H and Japan Blue Energy, TODA Corporation, the Tokyo Metropolitan Government, TOKYU Construction Co Ltd, Chiyoda Kenko, and researchers at Tokyo University of Science participated in the development to help Japan meet the growing demand for renewable hydrogen while demonstrating a new pathway for sustainable disposal of waste.

Located at the Sunamachi Water Reclamation Center near Tokyo, the facility will be capable of processing one tonne of dried sewage sludge per day and be able to convert it into kilograms of hydrogen per day. To put that into perspective, this quantity of hydrogen produced would be enough to fuel 10 passenger vehicles or 25 fuel cell e-bikes.


In addition to wastewater sludge, plastic, paper, municipal solid waste, and other refuse will be processed. The waste is heated to a high temperature and converted into a gas, from which pure hydrogen is extracted. The facility is carbon-neutral and generates its own fuel in a closed-loop process.

“Renewable hydrogen is an important clean energy fuel for Tokyo and the world. We spent over a decade developing this advanced process to convert waste into hydrogen, and it is encouraging to see hydrogen demand growing in Japan and globally, as we complete our first Tokyo hydrogen production facility.”  -  Naoki Dowaki, Ways2H Board Member and President of Japan Blue Energy.

"Producing renewable hydrogen from waste is a key pathway for increasing global clean energy supplies while addressing climate change and the global waste crisis.

This facility was built to support Tokyo's pioneering efforts on clean energy and waste reduction, and contribute to Japan's clean hydrogen and carbon reduction goals." - Jean-Louis Kindler, Ways2H CEO.
