Ministry of the Environment (MOE): Initiatives for Collaborating with
Local Communities and Demonstrating Low-carbon Hydrogen Technologies
Making use of low-carbon hydrogen derived from used plastics

For 5 years from 2015, MOE is implementing a low-carbon

Regional recycling of hydrogen
Demonstration of model for local production
and local consumptionhydrogen supply chain project to promote mid-to-long-term
efforts to reduce global warming via projects to reduce theamount of carbon in hydrogen as well as making earnest
efforts to use that hydrogen.
