CERTIFICATION SCHEMES
THE CERTIFHY™ SCHEME INCLUDES TWO DIFFERENT CERTIFHY™ LABELS
A label adds new information to a CertifHy™ certificate to further inform the consumer about specific independent criteria. CertifHy™ certificates and labels are different. A GO is the identity card of the molecule, a label is a «flag» added on the CertifHy™ certificate and refers to different criteria. Labels can be added either to a GO issued under a National scheme or under the CertifHy™ scheme.
CERTIFHY GREEN HYDROGEN
Originating from renewable sources (defined in art 2 of the Renewable Energy Directive II) and having a greenhouse gas balance below a defined threshold, which is min. 60% below the production of hydrogen through steam reforming of natural gas (benchmark process with a current GHG footprint of 91 gCO2eq/MJ). This GHG intensity will be regularly re-assessed, as the emission reduction % targets are due to increase over time.
CERTIFHY LOW-CARBON HYDROGEN
Originating from non-renewable origin, nuclear or fossil energy using carbon capture and storage (CCS) and potentially carbon capture and utilization (CCU) which is yet to be defined by European Law and having a greenhouse gas balance below a defined threshold, which is min. 60% below the production of hydrogen through steam reforming of natural gas (benchmark process with a current GHG footprint of 91 gCO2eq/MJ.) This GHG intensity will be regularly re-assessed, as the emission reduction % targets are due to increase over time.

USE CASE
THE PRODUCTS ELIGIBLE FOR THE CERTIFHY™ LABELS ARE
- H2 from renewable origin:
- Wind/solar/hydro electricity production. Those production processes have zero GHG emissions, hence zero carbon intensity by European convention.
- Biomass based production, which could come with GHG emissions as defined by RED II
- Low-carbon hydrogen from non-renewable origin:
- Nuclear or fossil energy using CCS (carbon capture and storage) & potentially CCU (carbon capture and utilization) which is yet to be defined by the European law.
The carbon intensity limit for renewable and non-renewable H2 is fixed at 60% below the amount of GHG emissions from a Steam Methane Reformer (SMR), being current Best Available Technology (BAT) for merchant H2 production. The GHG intensity of the BAT will be regularly re-assessed, and the emission reduction % targets are to increase over time.
The GHG intensity of H2 production batches that are not receiving any CertifHy™ label need to remain below the BAT benchmark. (e.g. Electrolysers using grid electivity when the RE plant is not producing).
