About the biogas register

The Deutsche Energie-Agentur GmbH (dena) – the German Energy Agency – developed the German biogas register in the year 2009 with support from the Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety (BMU) and in consultation with market participants and political and economic experts.

Management of the register by dena

The Deutsche Energie-Agentur GmbH (dena) – the German Energy Agency – is the competency centre for energy efficiency, renewable energy sources, and intelligent energy systems. dena's goal is for energy to be generated and used as efficiently, safely, cost-effectively, climate-neutral as possible, both domestically and internationally. To achieve this goal, it collaborates with players from the fields of politics, the economy, and society. dena's partners are the Federal Republic of Germany, the KfW banking group, Allianz SE, Deutsche Bank AG, and DZ BANK AG.

dena operates the German biogas register as the registrar. The registrar's duties include:

Due to its status as a semi-governmental organisation , dena is independent of players in the biomethane industry. Hence, it acts as a neutral registrar .

Steering committee — User committee

The realisation of the biogas register began in spring 2010, and was supported by 14 leading companies from the biogas and energy industry. These companies form the steering committee of the biogas register.

In 2015, the steering committee was converted into the user committee. This committee continues to advise and support dena with the management and further development of the biogas register.


The revision of the 2009 Renewable Energy Sources Act (EEG) brought with it one important change to the general parameters for the use of biogas for the generation of electricity and heat in Germany. Since then, apart from on-site electricity generation using biogas, there also exists the option of processing biogas to match the quality of natural gas and inject it into the natural gas grid. Electricity produced via the trade, dispensation, and use of biogas at other locations for the generation of electricity in combined heat and power installations is also eligible for reimbursements under the EEG.

In order to be eligible for reimbursement, it is necessary for the origin of the biomethane used to be documented according to the system specified in the EEG (which, among other things, includes the raw materials used and technical standards during biogas production and processing). From the perspective of electricity producers, a reliable record is essential, as the EEG permanently excludes a facility operator from reimbursements as soon as biomass that does not meet EEG requirements is used for electricity generation at any point in time. The 2009 version of the EEG contains corresponding requirements for EEG documentation in the individual value creation phases, but does not define any standard or corresponding processes.

In order to ensure an efficient and reliable documentation of biomethane and to enable the trade of biomethane across Germany, it is necessary to have documentation that is accepted by market players and whose processes are mostly standardised. This is what the German biogas register aims to do.
