Adding gas from biomass to the gas grid - SGC

the gas quantity used is equal to the energy content of the biogas quantity fed into the network."In 2000 the German Biogas Association established a working group on biogas introduction to thenatural gas grid. The purpose is to describe the technical possibilities for introduction of biogas andto prepare regulations of fixed fees for the introduced gas [lit.57]. The German Biogas Associationhas proposed to make a parallel law for introduction of upgraded biogas to the natural gas grid, tocompensate the injected upgraded biogas or the transport through the grid, to deduct the mineral oiltaxes from biogas etc.A shift to natural gas in the heat as well as in the power market is expected, however, injection ofupgraded biogas is not considered at all in a most recent climate study unlike other renewables,such as solar heat or combustion of biomass [lit.67].The cabinett has decided on July 26, 2000 to reduce CO 2 -emissions until 2005 as compared to1990 by about 18 - 20%, corresponding to a total absolute reduction of 180 - 200 million ton [lit.68].The actual deficit of some 50 - 70 million ton has to be shared by private households and inbuildings 18 - 25 million ton, by power suppliers and industry 20 - 25 million ton and by traffic 15 -20 million ton.Taxation and incentivesStromeinspeisungsgesetzThe federal act concerning the feeding of green electricity into the national grid defines regulationsfor purchases of systems with an installed capacity of less than 5 MW.The federal act concerning the feeding of green electricity into the national grid that came into forceon January 1st 1991 defines regulations for systems with an installed capacity of less than 5 MW.This regulation provides feed-in tariffs for small hydros, landfill gas and biomass electricity, which isfired with wood waste from the industry (installations up to 5 MW). Wind and solar energy are notincluded in the regulation as far as the capacity is concerned. The energy utilities are obliged topurchase electricity produced from renewables within their respective supply areas, at prices whichare fixed at the national level and apply throughout the year. The price is set on the basis of theaverage revenue (without countervailing tariff and sales tax) during the two previous years. Thevalue for 1995, as published in the official federal statistics, is the starting point for the 1997calculations and amounts to 0.096 €/kWh.The rate for electricity from hydro and biomass systems with an output of less than 500 kW totals atleast 80% of the average revenue (currently 0.077 €/kWh), for those with an output of more than500 kW the feed-in tariff is at least 65% of average revenue (0.063 €/kWh).page: 105
