EGEB: This Tokyo Facility Converts Sewage Into Clean Hydrogen

By Michelle Lewis| electrek | March 30, 2021

In today’s Electrek Green Energy Brief (EGEB):

  • A new facility in Tokyo that converts sewage into renewable hydrogen has been completed.
  • US president Joe Biden invites 40 world leaders to the virtual Leaders Summit on Climate in April.


A waste-to-hydrogen facility at the Sunamachi Water Reclamation Center near Tokyo Bay in Japan, which Electrek covered in October 2020, has now been completed as planned. It will process 1 ton of dried sewage sludge per day to generate 40 to 50 kilograms of hydrogen per day. That’s enough to fuel 10 passenger vehicles or 25 fuel-cell e-bikes.

In addition to wastewater sewage, plastic, paper, municipal solid waste, and other refuse will be 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.

The project is a collaboration between Japan Blue Energy Co. (JBEC), TODA Corporation, the Tokyo Metropolitan Government, TOKYU Construction, CHIYODA Kenko, and researchers at the Tokyo University of Science. The technology was developed by JBEC and is commercialized worldwide by Ways2H.

With 95% of the world’s hydrogen produced from natural gas and coal, Ways2H and JBEC are working to supply clean hydrogen to replace fossil fuels for mobility and power generation.

Ways2H is a joint venture between US-based Clean Energy Enterprises and JBEC. Ways2H’s CEO Jean-Louis Kindler told Electrek:

Because our waste feedstock is majority renewable, the carbon dioxide that comes out of our system is short-cycle and does not contribute to increasing greenhouse gases in the atmosphere. Waste-to-hydrogen can actually be better than green hydrogen, which is carbon neutral at best. If we connect our solution to a carbon sequestration solution, the whole system becomes carbon negative.

We strongly believe the future of transportation comes through several pathways so that we can transition away from gasoline and diesel. We will definitely have a mix of battery-electric and hydrogen fuel-cell vehicles. Hydrogen will play a major role in transportation.
