Quality infrastructure for green hydrogen

Overview of the status and impact of the innovation



Quality infrastructure encompasses all activities to assess and verify the quality and safety of green hydrogen–related technologies and components. These include technical standards; the use of metrology devices; and testing, certification, inspection, accreditation and quality management systems. Such activities give all stakeholders (including consumers, investors, markets, regulators and policy makers) confidence that the products, processes and services in the green hydrogen economy will work as expected.


Quality infrastructure for green hydrogen will ensure sustainable and safe production of green hydrogen and its derivatives, in turn lowering risks and spurring investment and development. It will also establish a level playing field that fosters fair competition and helps encourage co-operation and co-ordination in research, industry and policy making.

BOX 9.14 Standard and evaluation of low-carbon hydrogen, clean hydrogen and renewable hydrogen in China

A standard proposed by China Hydrogen Alliance and released in 2020 establishes a method for evaluating low-carbon, clean and renewable hydrogen across its life cycle. The goal is to promote the sustainable development of the entire green hydrogen energy industry chain from the source. The standard states that the threshold for carbon emissions per unit of hydrogen is 14.51 kgCO2eq/kgH2 for low-carbon hydrogen and 4.9 kgCO2eq/kgH2 for clean and renewable hydrogen (i.e. produced using renewable energy sources (Hydrogen Alliance, 2021).
