Figure 6.1: GGC 2047 model biogas plant
There are different practical models of biogas plants.
Floating drum digester, fixed dome digester and
deenbandhu model are common types of biogas plant.
Among these, fixed dome digester (GGC Model 2047)
with the capacity of 4, 6, 8 and 10 cu. m have been
widely adopted in Nepal. These models are feasible to
use up to 2100 m altitude. The cost of this model with 6
cu. m. is NRs. 24,621 in 2005/2006. The present policy
of the government has a provision of capital subsidy to
the biogas users based on geographical area and the
size of the plant as shown in Table 6.1.
Major organisations working on biogas technology in
Nepal:
Alternative Energy promotion centre (AEPC)/MOEST
is implementing Biogas Sector Partnership Nepal
(BSP-N) programme
Centre for Renewable Energy (CRE)
Center for Appropriate Technology Nepal
Nepal Biogas Promotion Association (NBPA)
representing more than 65 private companies
Please see the list of organisations involved in the biogas
promotion at Annex 5.
The reason for limited biogas plants installation in high
hilly mountainous region is the low average ambient
temperature as the optimum temperature for biogas
