3 I. Climate change and biogas facts

4 I. Climate change is the driver Rising temperatures, changing precipitation and seasons affect farmers jobs negatively. Climate change is a reality for farmers. High motivation for activities and investment. Biogas is the main field of farmers activities, besides solar and wind energy. farmers are driving energy transition!

5 I. CO 2 Concentration rises quickly source: IFM-GEOMAR

6 I. Facts about biogas in Germany 9000 biogas plants produce about 4% of the electricity consumed in Germany. Nearly no growth during the last few years. High production costs of biogas. No significant reduction of costs expected in future.

7 I. Facts about biogas in Germany Nearly no growth during the last years. High production costs. No significant reduction of costs expected for the future. Intense use of growing biomass for biogas in Germany requires around hectares. Good future for biogas in Germany?

8 Main obstacle: Lacking acceptance of politics and society for biogas plants. Biogas has to be more flexible, efficient, ecologic and less expensive!

9 II. Challenges and solutions

10 II. Challenges for biogas in Germany Surviving in an unclear tender system, combined with unclear signals of politics. Establishing flexible production of energy. Combining heat and power. Changing substrates towards liquid manure and droppings. Being more ecologically sound.

11 II. Challenges for biogas in Germany Biogas needs a clear place in the renewable energy world. Biogas has to cooperate with solar and wind. Biogas needs acceptance in society and politics. Biogas has to be an accepted part of the whole agricultural system. Biogas needs to contribute significantly to the success of climate protection.

12 II. Possible solutions Heat and power combine in bioenergy villages. Selling heat to industry and greenhouses. Flexible production of heat and power, mainly in the winter. Production of bio-lng for ships, busses and cars. Biogas can feed into the gas network. There are several survival strategies!

13 III. Examples

14 III. Bioenergy village Mauenheim Biogas plant (660 kw) produces 5 million kwh (electric) and 4 million kwh (heat). Wood biomass heating system (900 kw) produces additional heat in winter and as reserve. 4 kilometers district heating supplies 75 (of 105) households and two municipal buildings. Additional installation of private photovoltaic panels and solarheat.

15 III. Example bioenergy village Mauenheim Heat supply 90 % renewable. Electricity supply 920 % renewable. 900 % bioenergy, 20% solar. 820 % of electricity is exported!

18 III. Motivation for joining district heating Rise and variability of crude oil price. Old heating systems. Energy savings. Costs of chimney sweeper. Combination possibilities with other renewable energy sources (solar heat, stove). Climate protection.

19 III. District heating plus X New infrastructure: bioenergy village Bittelbronn

20 I. Energy village Leibertingen Photovoltaic on roofs since 1998 Biogas plant since 2005 Solar park 2011 Renewable district heating system combined with glass fibre 2012 Second renewable district heating system 2018 Windpark 2019?

23 IV. Vision energy belt

24 IV. Energy future for rural areas and cities Renewable energy belts surround towns. Investment in renewable energy production. Jobs and green growth for the region. Save energy and improve energy efficiency. Export of green products and services.

25 IV. Vision energy belt Potential of renewable energy production in rural areas is higher than its consumption. A lot of space, low population density, few industry. Primary goal: 100 percent renewables in rural regions. Secondary goal: energy export to towns.

26 IV. Vision energy belts Main challenges: Reconciliation between rural areas towns. Energy transport to the towns. Energy storage. Smart grid.

27 Offshore wind Rural energy belts Towns High energy consumption Low renewable energy production Low energy consumption high renewable energy production DESERTEC wind and solar Energy transport

28 IV. Flow of energy and resources vs. money Decentralized renewable regions energy flow energy flow money flow region

29 V. Future of biogas

30 V. Future of biogas in Germany Accepted part of energy transition. Effective contribution to climate protection. Competitive production of flexible energy for electricity, heat and mobility. Intensive use of manure and organic waste. Ecologically sound substrate production. Local and regional substrates.

31 V. Future of biogas in Germany Biogas remains a driver of energy transition. Biogas is a smaller sector than solar and wind. The amount of biogas plants will decrease. Biogas is a transitional technology. Biogas can play a role in freight haulage.

32 International Cooperation is needed

34 II. Biogas heute und morgen Biogasproduktion Strom und Wärme in D GWh 820 GWh GWh GWh GWh GWh GWh GWh

35 II. Biogas heute und morgen Anzahl Biogasanlagen und Anteil am Strom- und (Wärmeverbrauch) in D Biogasanlagen 0,3 (0,1) % Biogasanlagen 1,4 (0,3) % Biogasanlagen 2,5 (0,5) % Biogasanlagen 4,6 (0,8) %

36 III. Biowärme heute und morgen Fakten Biowärme hat in D eine Holztradition. Energiewende im Wärmebereich geht viel langsamer als beim Strom (kein EEG). Preisentwicklung Heizöl und Erdgas stark steigend aber viel volatiler als Strom. Thema Versorgungssicherheit nur bei Wärme nicht bei Strom. Austauschrate bei Heizungen nur 1 Prozent pro Jahr.

37 III. Biowärme heute und morgen Fakten Biowärmeanstieg 2003 bis 2013: Festbrennstoffe Haushalt plus 25%. Festbrennstoffe Industrie plus 100% Festbrennstoffe Kraftwerke plus 300% (aber Rückgang seit 2009) Biogene Brennstoffe flüssig plus Faktor 10 Biogaswärme plus Faktor 40
