DEFINITION AND BENEFITS

CertifHy™ has established a system of electronic certificates, called Guarantee of Origin (CertifHy™ GO) certificates.

CertifHy™ GOs enable EU-wide consumption of non-renewable and renewable hydrogen regardless of the location; by using a CertifHy™ GO, the corresponding quantity of hydrogen consumed acquires the properties of the hydrogen covered by the CertifHy™ GO.

A CertifHy™ GO 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™ GO certificates are maintained in a CertifHy™ Registry, a central database that will manage the CertifHy™ GOs’ life cycle for every account holder.

The CertifHy™ Registry generates unique CertifHy™ GOs 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™ GO schemes are typically in Europe, however CertifHy’s™ objective is to go beyond Europe’s borders in the future.

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.
