Project Achievements: CertifHy

Hydrogen, a common industrial gas generally used in the chemical and petrochemical industry for various processes, has to date been mainly produced through the chemical process of steam reforming of coal or natural gas, generating carbon dioxide (CO2) as a side product. This, however, is not the only possibility.

Hydrogen can also be produced through the steam reforming of biogas, or through an entirely different process, water electrolysis, which uses water and electricity as the "ingredients". Can the resulting hydrogen be considered green- in the latter case, in particular if the source of electricity is renewable? And if so, how can the users receive reliable information on the origin of the hydrogen sourced?
These are the questions that project CERTIFHY has tackled through an FCH JU Coordination and Support Action which ran over two year between end 2014 and end 2016.
With the endorsement from many stakeholders interested in the study, the project was able to formulate a European definition of "green hydrogen" based both on the carbon dioxide-intensity of the production process and the renewable nature of the energy and feedstock input. In parallel, the concept of a “low carbon” (low CO2 emissions but not renewable energy) and grey carbon (neither CO2-lean nor renewable energy) have been proposed to further differentiate the hydrogen that does not qualify as green.
In parallel, the project has analysed the hydrogen market and the appetite for a green product, it has proposed a “Guarantee of Origin” (GoO) scheme and a concrete roadmap for its implementation.
