A compilation of information on particularly frequently asked questions relating to the verification and trading of biomethane in the German Biogasregister.
Yes, the parallel verification of biomethane quantities in both verification systems is possible and even necessary in certain cases.
One example of this is the use of biomethane within the framework of the Fuel Emissions Trading Act (BEHG). On the one hand, this requires proof of sustainability, which is recorded via the BLE's NABISY system. On the other hand, additional criteria that are not covered by NABISY can be provided via the dena Biogasregister in accordance with the criteria matrix.
Requirements for parallel verification in the dena Biogasregister
The following points must be observed to ensure that parallel verification is documented in a comprehensible manner:
Audit report:
The auditor or assessor who carries out the audit of the biomethane quantity as part of the BAD must explicitly note the parallel verification in the audit report.
This entry serves as proof that the biomethane quantities are recorded simultaneously in both systems without any discrepancies.
Prohibition of double marketing:
Parallel verification does not mean that biomethane quantities may be used simultaneously in different marketing paths. If the verification is rebooked or retired in one system, it must also be rebooked/retired in the other system.
Quantities that are recorded in both the dena Biogas Register and Nabisy and for which no biogas register extract is required because they are used solely as fuel can be permanently decommissioned in the dena Biogas Register. To do this, these quantities are transferred to the dena trustee account.
The account number for the transfer within the Biogas Register is: denatreuhBK15001
Please send us an email with a brief explanation to support(at)biogasregister.de if you are transferring or have transferred quantities to the dena trustee account. The registry will then permanently deactivate the quantities. Should you require proof, we will send it to you on request. For your own records, you can download the transfer document directly from the Biogasregister.
