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

Slide 8
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

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
