Off-Grid Hybrid Renewable Energy System - A Solution To The Problem Of Increasing Particulate Pollution Scenario In The Mangrove Ecosystem Of Sundarbans

摘要

The susceptibility of the mangrove ecosystem of the Sundarbans to increased pollution burden is undoubtedly a matter of concern. Over the years, there has been a considerable rise in the atmospheric pollution scenario in the Sundarbans particularly with respect to the particulate fractions (PM_(10) and PM_(2.5)). The different types of anthropogenic activities to meet the daily energy demand happens to be the major contributor to the pollution burden in the area. Thus the most important objective seems to find an alternative energy source to cater to the needs of the locals in the Sundarbans to protect the unique biodiversity. In this context, the present paper presents the particulate pollution scenario and feasibility analysis of off-grid hybrid energy system for the mangrove ecosystem of the Sundarbans, India which is one of the world's largest mangroves and an area infested with a host of rare and endangered species. The hybrid system is modelled focusing on the viability of the different components of a hybrid energy system, like a wind turbine, solar PV alongwith fuel cell. Different parameters, such as net present cost (NPC), cost of energy (COE) and generation cost (GC) have been considered during the optimization of the system. The analysis shows encouraging results related to the use of off-grid hybrid energy to reduce the increased atmospheric pollution generated from the conventional energy sources prevailing in the Sundarbans.
