A sustainable energy approach for pumping and irrigation in the Barind Region of Bangladesh

Abstract

The continuous use of fossil fuels has prompted scientists and researchers to convert to renewable sources for powering water pumps. By converting sunlight into electrical energy, the photovoltaic (PV) panels are able to drive the water pump or produce electricity through an inverter. Over the past few years, scientists have been working on developing more e cient solar-powered water pumps. A summary of existing research and development activities for developing a dependable and cost-effective solar irrigation system is described in this study. The paper outlines Bangladesh's present irrigation scenario, the problems associated with solar irrigation systems, and government policies and actions promoting solar irrigation. The main objectives and aims of the proposed project are to develop an e cient standalone hybrid solar PV-pyro-oil generator-based water pumping system for the Barind tract and off-grid remote areas.Moreover, the techno-econo-environmental feasibility of the proposed project has also been evaluated. The total life cycle cost and investment payback period of the 20-year project were found to be 14,377.32 dollars and 7.04 years, respectively. Moreover, the project's internal rate of return and CO 2 reduction potential were found to be 21% and 197.1 tons, respectively. Therefore, the project is sustainable and feasible, which provides a guideline for researchers and investors.
