Implementation of Decentralized Power Generation by Biogas Digester: Policy in Perspective
Journal Title: Carbon - Science and Technology - Year 2015, Vol 7, Issue 2
Abstract
This paper aims to evolve innovative system for fast track implementation of decentralized power generation by biogas digester across the country commensurate with estimated potential of this energy resource. The methodology is based on the principle that necessity of a process or facility for human lively hood generates demand of a new system if that is competitive enough to impress society by its value to meet the standard of usability economically and technically in all respect. Firstly, the study described a network of communication to propagate knowledge about the benefit, cost and operation of biogas digester to serve multiple purposes among policy makers and other stakeholders all over the country through distance mode programme and training of the human resources by simulating the process for training programme. Secondly, analysis by cause and effect method focused on major issues related to implementation of power generation by biogas that identified factors corresponding to the problems. Next the study attempt to focus on supply chain management for controlling those factors supported by administration with financial, technical facilities ensuring trouble free dynamic process from procurement of substrate through input to digester till delivery of electricity to the consumers. The study identified driving variables between resource centre and delivery stage of the supply chain that has influence on methane production related to power generation. The mathematical analysis reveal that optimum yield of biogas is independent of daily feed stock and improving methane fraction of biogas is possible by monitoring temperature and pH value within limited span of Hydraulic Retention period (HRT).The study observed by mathematical analysis that cost of power generation from biogas digester is dependent on the cost of substrate for biogas generation and the other fixed cost of the process. Bio gas digester cum power generation policy has been analyzed for rural and urban area focusing on the constraint at different stages.
