6 II. Energy Supply by Biogas Status Quo in Germany

7 II. Status Quo in Germany Biogas (incl. Biomethane) 2017 Plants: ~8,900 plants 8,700 on-site electricity conversion of biogas 200 upgrading to biomethane Installed electrical capacity 5,2 GW el Biogas plants [number] Gross electricity production 32,5 TWh el Heat supply 17 TWh th Sources: Daniel-Gromke et al. 2017, DBFZ Report Nr. 30; Daniel-Gromke et al. 2018, Biogasinnovationskongress 2018; UBA 2018

8 II. Status Quo in Germany Substrate Input in Biogas Plants 4,2% Mass-related 2,4% Energy crops Animal excrements Municipal biowaste 14,8% Energy-related 4,6% 3,9% 44,5% 48,9% Industrial and agricultural 76,7% waste/residues n = 367 DBFZ 08/2017 (Without upgrading plants; Source: DBFZ operators survey 2017, reference year 2016) Sources: Daniel-Gromke et al. 2017, DBFZ Report Nr. 30

Example Project at DBFZ SchlauFe SchlauFe Continuous digestion in a gastight geotextile tube (Funded by Federal Ministry of Education and Research; Projektträger PtJ) National Research Strategy BioEconomy 2030 Natural cycle-oriented, sustainable bio-based economy Carrying the promise of global food supplies that are both ample and healthy high quality products from renewable resources Source: BMBF Bioeconomy in Germany (2015)

15 III. Biomass Potentials c. Example Project at DBFZ SchlauFe SchlauFe Continuous digestion in a gastight geotextile tube (Funded by Federal Ministry of Education and Research; Projektträger PtJ) Intention Save Resources Reduce emissions Avoid silage effluent leakages HUESKER SYNTHETIC GmbH Tube for dewatering by practice partner HUESKER SYNTHETIC GmbH Objective Development of a costefficient procedure for continuous digestion of water-rich biomass sources

16 III. Biomass Potentials c. Example Project at DBFZ SchlauFe SchlauFe Continuous digestion in a gastight geotextile tube (Funded by Federal Ministry of Education and Research; Projektträger PtJ) Identification of potential markets Progress Identification of (inter-) national biomass sources e.g. residues of olive oil and wine production Development of a technical concept with partners from practice LEHMANN UMT GmbH Bioextrusion for disintegration by practice partner LEHMANN UMT GmbH

17 IV. Perspectives for Biogas Plants

18 IV. Perspectives for Biogas Plants in Germany a. Renewable Energy Sources Act (EEG) Expansion of renewable energies highly EEG-driven in Germany Until 2016: fixed feed-in-tariff for 20 years 2017: change to tender system Until 2030: Guaranteed 20-year-funding expires for many plants Fotolia.com Possibility for existing plants to extend tariff for another 10 years by sucessful participation in tenders

Renewable Energy Sources Act (EEG) Expansion of renewable energies highly EEG-driven in Germany Until 2016: fixed feed-in-tariff for 20 years 2017: change to tender system Until 2030: Guaranteed 20-year-funding expires for many plants Fotolia.com Possibility for existing plants to extend tariff for another Precondition: flexibilisation 10 years by sucessful participation in tenders

20 IV. Perspectives for Biogas Plants in Germany b. Business Models Search for further economically sustainable business models Flexibilisation Biofuels Biomethane Emission reduction Increase of efficiency Safety
