Japanese corporation Showa Denko (SDK) will start to supply “low-carbon” hydrogen (H2) gas made from used plastics to Kawasaki King Skyfront Tokyu Rei Hotel as an energy source for fuel cells.

This is the first case in the world to introduce low-carbon H2 gas made from used plastics into fuel cells set up in a hotel. Kawasaki King Skyfront Tokyu Rei Hotel, set to open on 1st June 2018, will use the low-carbon H2 as energy source to be converted into electricity and heat through large-sized fuel cells.

Explaining the process, SDK said, “In 2003, SDK’s Kawasaki Plant introduced a method to extract H2, which is used as raw material to produce ammonia, from used plastics. By utilising used plastics as raw material, this H2 production method not only reduces consumption of fossil fuels but also promotes reuse of carbon dioxide (CO2) gas, which is generated as a by-product of the H2 extraction process, by converting it into dry ice. Thus, this H2 production method considerably lowers the burden on the environment from that of conventional production method.”

SDK’s ‘Demonstration Project to Promote Local Consumption of Locally Produced Low-carbon Hydrogen Gas Made from Used Plastics’ has been accredited as an official project under the framework of ‘FY 2015 Regional Cooperation and Low-carbon Hydrogen Technology Demonstration Project’ commissioned by the Ministry of Environment. SDK’s project has also been accredited as a part of ‘Kawasaki Eco-town Project’, which is promoted by Kawasaki City.
