Barriers to installing Biogas

One of the major barriers in installing bio gas components can be the technical constraints. It is important to see the feasibility of installing a large scale biogas program in any place and if it fits in the local constraint. For a productive bio gas plant, it is important to maintain the minimum digester temperature throughout the year, night stabling, water availability. Space is another important consideration. Some of the farmers from higher Himalayas elevation report insufficiency of gas during colder months. These are some of the technical barriers that may come up during the project.

The technical barriers shown by AEPC are as follows:

  • Research & Development: lack of research and development to continuously improve and innovate the technology to improve efficiency and additional end uses for income-generating activities;
  • Orientation of the construction companies: all the companies engaged in plant construction have a profit motif, there is some negligence about the quality control and after-sale-service.

When installing biogas availability of manure and water as input needs to be assured to be close to the plant’s inlet and correct plant operation should be ensured. These can be addressed by user trainings, illustrative manuals, to name a few.

Sometimes, the installation cost can be too much for the people to be able to afford. At such times, subsidy policies are expected to make the installation possible. The barrier can also be the question of how to scale up and stimulate bio slurry use in the community, which can be a very useful trading opportunity too. Trading appliances can be another hindrance which can be supported by the reduced government taxes.

The financial economic barriers are as follows:

  • “High investment costs required for plant installation, because it is probably the largest investment made by a farmer. Cost reduction without compromising reliability is an important aspect;
  • Farmer’s affordability: the negative growth in agricultural sector and inflation has adversely affected the farmer’s affordability. Lack of adequate income-generating activities and support required for such activity is an important barrier for technology dissemination as biogas;
  • Access to credit: loans for the construction of a biogas plant is difficult to an ordinary farmer as often mortgage is required to advance the loan. Sufficient properties are often not owned.” (AEPC, 2000)

The social barriers is identified to be: Illiteracy. Studies show that 75% of the biogas owners are educated. However, it is very difficult to convince uneducated farmers about its importance.

To address this problem, usually information is disseminated through the radio broadcasts, and information are prepared in printed form with very little text.
