DEFINITION AND BENEFITS
CertifHy™ has established a system of electronic certificates, called CertifHy™certificates
CertifHy™certificates enable EU-wide consumption of non-renewable and renewable hydrogen regardless of the location; by using a CertifHy™certificate, the corresponding quantity of hydrogen consumed acquires the properties of the hydrogen covered by the CertifHy™certificates.
A CertifHy™certificate is an electronic document providing proof that a given quantity of hydrogen is produced by a registered production device with a specific quality and method of production. The CertifHy™ certificates are maintained in a CertifHy™ Registry, a central database that will manage the CertifHy™certificates’ life cycle for every account holder.

The CertifHy™ Registry generates unique CertifHy™certificate for each registered production device and tracks them during their life cycle, so that double use within the registry is excluded. The CertifHy™ Registry is fraud-resistant and can provide reports for different kind of purposes (for the account holder itself, for competent bodies, for European and national statistics, for the registry administrator, etc.).
CertifHy™certificate schemes are typically in Europe, however CertifHy’s™ objective is to go beyond Europe’s borders in the future.
CONTENT OF A CERTIFHY™ GO
CertifHy™ GOs provide information about
- CertifHy™ GO identity: unique ID number, date of issuing, cancellation date
- Information on the plant which produced the hydrogen (location, start date of operation, operator...)
- Time of production of the hydrogen
- Energy source of the hydrogen (fuel or heat) and technology
- Whether the hydrogen production has received financial support or not
- Share of renewable energy
- Greenhouse gas intensity (amount of CO2 equivalent per unit of energy) of the hydrogen
The full content of a CertifHy™ GO is defined in the CertifHy™ scheme which can be found here:
FOCUS: GHG CALCULATION AND ALLOCATION
Our GHG calculation is based on a methodology developed by CertifHy™ in collaboration with its stakeholders:
The greenhouse gas (GHG) intensity as established in the CertifHy™ GO is based on CO2 emissions of the whole production pathway (“well-to-gate”) to produce hydrogen with a purity of at least 99.9%vol and a gauge pressure of at least 3 MPa. The “Well-to-gate” pathway means CO2 emissions from exploration to the production process, including transportation until the production process.
For each production pathway (electrolysis, SMR + CCU, chloralkali, etc.), CertifHy™ performs a case study and develops a dedicated GHG allocation method which is then used as part of the CertifHy™ scheme.
