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

The establishment of another village-based clean-energy-development enterprise is in progress, supported by the Wuppertal Institute for Climate, Environment and Energy, through the 6th round of their Sustainable Energy Project Support (SEPS).  The project consists of the establishment of a dairy, a biogas plant, a biogas-fuelled electricity generation unit, and through these, the extension of electricity distribution and supply.  The dairy provides employment and income, with its waste being used as sustainable fuel-supply for biogas-generation.  Electricity will be generated through a 100% biogas-fuelled generator and supplied to homes for lighting and for any other services, as required, when grid supply is not available.  The revenue from the sale of milk and digester-effluents (as manure) will supply the required income to provide for any additional operating costs, ensuring financial sustainability.

This enterprise is being established in Kempapura, Ramanagara district, Karnataka state (south-west India).  The cattle-rearing centre has been constructed, and people have been trained for the caring of cows and calves.  The construction of the biogas plant was completed simultaneously; this plant consists of a cylindrical floating-drum digester, as well as inlet and outlet tanks.  The biogas digester has been fuelled with cattle-waste and biogas has been accumulating in the gas-holder.  A pipeline has been drawn to the generator room, and the engine-generator is now being tested.

Extension  of sustainable energy services – Renewable energy for food preparation and processing

We at IEI-Bangalore, continue to pursue our mission of facilitating sustained access to improved energy services, particularly for the rural poor.  These services are based on the conservative use of energy (i.e. more efficient devices) and/or clean and renewable sources, for environmental sustainability, and are linked with income generation for economic sustainability.  Our activities include in-house research and field demonstration.  Programmes in the latter category include biogas delivery for stove fuelling to every home in a village, based on a co-operative dairy-fuel model, improved irrigation facilities to small farmers through efficient water pumping and application systems, and currently, village-based generation of electricity from a renewable source (described above).
While our demonstration-projects have each served a village or cluster of villages, we are also involved in further extension of sustainable energy services.  The highlights of one of our projects -- Energy enterprises for rural development: the case of clean cooking fuel [Click here] -- has been included in the brochure on Renewable energy technologies for food preparation and processing of the Wuppertal Institute’s “Wisions” of sustainability.  Based on case studies from various parts of the world, this booklet provides useful information on improved biomass-fuelled stoves, biogas-fuelled stoves, and solar-powered cookers, ovens, and dryers.  It summarises details on a range of issues – technology, operation and maintenance, financing and management, environmental and social impacts, lessons learnt from the project, and the possibility of replication.
