Slide 4

Biogas in Germany Agricultural Biogas in Germany developed over about 40 years The mountain moved in 1990: first feed in law (StrEG) with tariffs for injected renewable electricity This law was completely changed in 2000 (EEG) and amended every two to four years after monitoring and evaluation. We now celebrate 23 years of feed-in-tariff, among this 13 years of EEG. There are two regulating circles: a) the legal circle b) the insurance and banking circle. They take care for environmental and compensational affairs on one side and for safety and service life on the other side. Chapter 1

Chapter 1, Regulating circles

Slide 6

There are 4 conditions which make biogas a success in Germany Priority access of the BGP to the electrical grid Priority injection of renewable electricity Priority acceptance of electricity Feed-in tariff structure Banks know the value of biogas and like to finance up to 80% loan. Insurances insure the risk of failure and break down since they know the reliability Chapter 1, Success story in Germany

The role of the GBA The role of the EBA The German Biogas Association is with 4800 members the strongest association in Europe. It is speaking with one voice and lobbying in Germany for all topics concerning biogas. Chapter 1, Success story in Germany The European Biogas Association is representing the biogas interests in Brussels.

Slide 9

Cooperation Spare parts, implements, turn key plants, design, engineering, project development, approval planning. Chapter 1, German companies offer services, seeking for cooperation Source of the map: AHK-paper: Market entry in Vietnam opportunities and challenges

Monitoring and evaluation

Slide 11

Income through electricity Is it possible to reduce operational cost by a factor of 4/11 or 64%? Chapter 2, Cooperation Germany - Vietnam

Slide 12

Options for cost reduction Wages: 10 to 20% of those in Germany Concrete as construction material: 50% of that in Germany? Engine-generator-set instead of CHP-unit Innovative local low-cost materials:? Chapter 3, Feasibility and operational cost Options for combined income generation Electricity: cover farm consumption, injection options Engine-generator-set only Co-generation, CHP-heat in addition Heat only, for productive use (drying, heating, steam generation) Fertilizer in digestate, liquid or solid, composted, pelletized? Export?

Income through fertilizer is higher than electricity Chapter 5, Digestate, comparative specific income

Slide 18

In Vietnam, there is high potential of reducing operating costs a) due to the cheap labour force and b) through reduced investment, i.e., if a large part of the biogas plant is manufactured locally. Manufacturing options are an opportunity and challenge for those German companies who seek cooperation. More advice is required. If the value of the fertilizers is fully activated every year, income through biogas may be doubled. Conclusion
