6 Germany s Legal Framework for Biogas(1/2) EEG (Renewable Energy Act) priority in grid connection guaranteed feed-in tariffs for 20 years as from commissioning CHP plants that use virtual biogas transported by gas grid ( bio-methane ) are covered by EEG Regulation for gas grid access bio-methane has priority in gas grid access gas grid operator has partly to finance and to operate the injection unit standardised quality requirements for biogas independent of local gas quality (grid operator has to adjust quality of gas to be injected) balancing of feed-in and take-out on a yearly basis with 25 % flexibility refund of 7 /MWh avoided grid costs leads to negative costs for transportation of bio-methane via gas grid Page 6 - Biogas Heating Networks

7 Germany s Legal Framework for Biogas (2/2) EEWärmeG (Renewable Heat Act) For new buildings particular proportions of renewable heat is obligatory (% of the heat consumption): o 15 % covered by solar panels or o 30 % covered by biogas in CHP or o 50 % covered by solid or liquid biomass, geo-thermal heat, or heat pump or o 50 % covered by conventional CHP or waste heat recovering or o heat supply by district heating with reasonable proportion of renewable energies or 50 % CHP o duty can also be fulfilled by insulation over standard Page 7 - Biogas Heating Networks

8 Biogas Heating Networks: What does Dalkia in Germany Page 8 - Biogas Heating Networks

9 Example: Biogas Plant Barth Biogas plant & feedstock commissioned in t/a manure (slurry) t/a organic waste (e.g. fat trap contents, agro-industrial waste) Partnership with farmers joint venture with 3 farmers supply of manure and utilisation of digestate as fertilizer Heat utilisation until today: onsite gas engines (866 kwe) without heat utilisation new concept under realisation: installation of a biogas pipeline to the village centre of Barth & a hybrid CHP module (fuel cell 200 kwe (MCFC) & gas engine 200 kwe) heat sales to the DH network of Stadtwerke Barth Page 9 - Biogas Heating Networks

10 Example: Biogas Park Altmark 10 identical biogas plants in a region of 20 km each 500 kwe each t/a energy crops silage (maize, rye, grass) Partnership with farmers sites leasehold energy crops cultivation / supply plants feeding Heat utilisation new district heating for 8 villages customers are keeping their individual heatings and use DH alternatively or in addition wood drying (with excess heat) Page 10 - Biogas Heating Networks

11 New Developments in Biogas District Heating Page 11 - Biogas Heating Networks

12 Change from Onsite Gas Engine to Bio-Methane yesterday biogas (onsite power generation) today / tomorrow bio-methane (upgrading & grid injection) biogas upgrading public gas grid CHP/power generation biogas production NEW power generation heat market fuel market limited sites with complete heat utilisation better heat use -> optimised efficiency new markets for utilisation Page 12 - Biogas Heating Networks

13 Germany s Bio-methane Market Today, there is no liquid biomethane market! 17 Bio-methane plants in operation: 560 GWh (i.e. 42M ) for comparison: natural gas consumption in Germany 2008: 922 TWh Plants/projects under development/construction: ca GWh (118M ) Page 13 - Biogas Heating Networks

14 Requirements for Bio-methane Market Development Market conditions / legal framework appropriate support for green electricity & green heat supply (in Germany: EEG, EEWärmeG, GasNEV) privileged access to the gas grid for biogas and practicable rules for balancing of biogas (in Germany: GasNZV) standardisation of gas quality & measurement requirements for grid access (in Germany: GasNZV) Technology optimisation of gas-upgrading technology: o power consumption o methane loss o small units grid injection technology o small compressor units for big pressure differences o gas quality measurement: cheep but calibratable analysers Page 14 - Biogas Heating Networks
