Biogas Grid

Biogas based Cooking Grid

Gram Oorja believes that rural energy needs can be fulfilled from local resources. This will lower the dependence of rural India on the fossil fuel based systems making them self-sufficient with respect to their own energy needs. Gram Oorja has already been active in rural energy solutions and has successfully implemented more than hundred renewable energy projectsimpacting the lives of close to 30,000 villagers. Learning from experiences in rural India, Gram Oorja has proposed a unique solution of a Biogas based cooking grid, which will be used to provide cooking gas to every household in the community.

A biogas grid is one where there is a central biogas plant in the village where all the cow dung is deposited by the villagers daily. This biogas is then transferred using a pipeline to each household, where the flow is measured and the pressure is regulated, in order to provide a satisfying cooking experience.

    Community bio-gas plant, piped gas network

  • Community bio-gas plant based on cattle manure, food or agro-waste (subject to availability) and piped gas distribution network
  • Gas can be used for cooking or process heating - time to cook food are the same as for LPG
  • Bio-gas usage can be metered and charged to the consumers based on a predetermined tariff rate which can take care of operations and maintenance costs
  • Estimated cost: 30-35 lakhsINR. for communities with 50-60 households
  • Beneficiaries:
  •  Communities using firewood for cooking

     Communities facing difficulty in getting LPG cylinders may be because of remoteness

     School refectory or mid-day meal kitchens in semi-urban or rural schools

  • Geography: Anywhere across India
  • Projects done: Piped gas network for community in Gawaliwada, Pune district, Maharashtra

    Benefits and Impact of Biogas based cooking grid

  • Reduction in smoke-related health problems due to burning of wood.
  • Saves time, energy and money spent in getting firewood/kerosene/LPG.
  • Increases time for family and for productive cottage industries.
  • Reduced burden on forests due to less dependency on firewood.
  • Nominal harmful greenhouse gas emissions due to the use of clean energy.

    Role of Gram Oorja

    Gram Oorja executes entire project of biogas cooking grid from preliminary village survey to commissioning of the project. Formation of village energy committee, setting up the agreeable rates for raw material and biogas and structuring of economical modal forthe village are done with help of local NGO and villagers. Gram Oorja does the design, implementation and commission of biogas grid to supply biogas to each beneficiary from the village. Gram Oorja facilitates training of the Biogas plant to two-three technical persons from the same village. The basic maintenance requirement of the plant is also communicated to the villagers so that they are aware of how to run the plant efficiently.

Gawaliwada Biogas Cooking Grid

Gram Oorja has implemented biogas cooking grid at Gawaliwada for 14 households as a demonstration project. Gawaliwada is a village located at Mulshi block of Pune district, Maharashtra. Dairy farming is main occupation of the villagers.

The size of Biogas plant is 20 Cu. m and gas storage capacity at the site is 30 Cu. m.

Generated biogas is passed through the scrubber to remove Hydrogen Sulphide from the gas. Biogas is boosted with blower and passed to the main gas grid.

Bio-gas is transported to around 500 m from project site. Each consumer is provided with the gas flow meter. The tariff is set for usage of bio-gas.

The local energy committee, namely Kalbhairav Oorja Samiti, collects the amount for monthly usage, which is used for operation and maintenance of the plant.
