Demonstration Project  in progress - Powering a village sustainably: generating electricity from waste-based biogas

The main purpose of this project is to demonstrate sustainable rural access to electricity-services through a community enterprise that generates electricity based on a local renewable resource, facilitated by integrated income-generation activities.

Such an energy-development enterprise has been established in Kempapura village (13° 8’ N, 77° 11’ E), Karnataka state (south-west India).  It consists of a 35 m3 biogas digester and accessory-tanks, a newly-established dairy (with 40 cows and the 15 female calves born to them), a 100% biogas-fuelled 20kVA engine-generator, the extension of the distribution lines to un-electrified homes, and through these, electricity supply to the village.

The dairy provides employment as well as income from milk sales, with its waste being used as fuel for biogas-generation.  Biogas is generated throughout the year, with the gas stored at the plant enabling electricity generation whenever required.  Electricity is currently being generated through the biogas-fuelled system only during periods when supply from the Bangalore Electricity Supply Company (BESCOM), the regional distribution unit of the state’s power utility system, is not available to the area.  The biogas-plant effluents are being used as manure.

The main financial support was obtained from the Wuppertal Institute for Climate, Environment and Energy, through the 6th round of their Sustainable Energy Project Support  programme [SEPS].

New project - "Value-addition to food crop processing: converting banana plant waste to cooking fuel"

We have just commenced a project through which we intend demonstrating a case of food-crop-residues being converted to cooking fuel, financed by enhanced crop revenues. 

A co-operative enterprise is being developed in Ramanagara district of Karnataka.  Banana-plantations will be developed at small subsistence-farms, where irrigation-facilities will be provided to enable their participation in the cultivation; these costs will be recovered over time through shares of the harvest.  Residues (pseudo-stems, leaves, etc.) from these and other existing banana plantations will be used to fuel two anaerobic-digesters.  The biogas so generated will be supplied to the surrounding households as cooking fuel.

Thus far, arrangements have been made with farmers agreeable to participate in this energy-development enterprise, farm lands are being prepared for cultivation and irrigation facilities being installed. 

Improvements will be implemented along the food growing and preparation chain, through the integration of:
·        value-addition to food-crop-production and, thereby, increased farm income and poverty reduction,
·        processing of (waste) crop-residues for the generation of a renewable-energy source,
·        delivering clean cooking fuel regularly to rural homes to replace the burning of solid biomass, and
·        ensuring long-term sustainability.

This project has been selected for funding by the Wuppertal Institute for Climate, Environment and Energy, through the 7th round of their Sustainable Energy Project Support (SEPS).
