Development of biomethane gas grid feed-in in Germany
between 2006 and 2011 showing strong growth in later years.
Comparison of the number of facilities with the total capacity of gas grid
feed-in shows a trend to larger facilities over the years (Source:
unpublished data from the dena project 'biogaspartner').
buildings with heat from biomethane is not covered - it is still considered a
sleeping giant by the biomethane industry.
Green gas products are still a niche market. However, they are developing
- driven by rising environmental awareness and also by the above-
mentioned obligations for renewable heating of new buildings.
A defacto end of the 'book and claim' trading of biomethane certificates
was the result of the 2011 EEG update (for a definition of book and claim
see Section 19.3). The use of topic and claim certificates is no longer
applicable for Germany's national support schemes. This hit many market
participants very hard as they had transferred large parts of their unsold
quantities into valid certificates of this type in the hope of selling them in
later years when demand improved. For the (relatively small) green gas
product market, this path can still be chosen.
19.3 Biomethane certification and mass balancing
As a means of direct promotion of biomethane feed-in by government
support schemes, two important general approaches can be observed - feed-
in tariffs and quota obligations. Indirect promotion for biomethane is
achieved by other means, such as tax refunds or financial support for new
projects.
Laws establishing a feed-in tariff pattern define a guaranteed price for the
feed-in of renewable energies into the public (power) grid for a long period
