Clean Hydrogen Certification System Operation Plan

This plan implements a hydrogen certification system to measure greenhouse gas emissions from hydrogen production and importation. The hydrogen certification system grants the clean hydrogen certification if the processes emit greenhouse gases below a certain threshold as well as providing administrative and financial support. The Korean government has finalized the country’s clean hydrogen certification standard of 4 kg CO2eq/kg H2 by considering international trends and domestic conditions such as technology level and infrastructure. Hydrogen that passes the certification standards is granted one of the four grades of the clean hydrogen certification depending on GHG emission levels.
