Biohydrogen falls under the regulations for advanced biofuels and can therefore be certified in the REDcert or ISCC system recognised for GHG quota trading.

In addition, there are two other voluntary certificates with a wide reach:

• CertifHy (Widespread throughout the EU)
• CMS 70 (TÜV Süd, Germany)

Here, hydrogen is considered ‘green’ as soon as a GHG reduction of at least 70% is achieved. Recognised technologies include electrolysis, steam reforming, biomass gasification and pyrolysis.
