Pilot application on solar energy combined electricity grid to a rural water supply station in Can Tho city

Abstract

Since 2008, a Clean Development Mechanism project, which can be counted towards meeting Kyoto targets, has been formed by Japan International Research Center for Agriculture Sciences and Can Tho University (JIRCAS-CTU). In this project, My Phung Hamlet, My Khanh Village, Can Tho City was chosen to implement a greenhouse-gas emission reduction model. One of the activities of the project, a domestic water supply plant was surveyed, designed and installed. A part of electricity sources used for plant operation is generated by solar panels. The selection of renewable energy is to fit the objectives of JIRCAS-CTU Project.

The project objective is to introduce of renewable energy for My Phung Water Supply Station by selecting one of the natural unpolluted, clean and rich energy resources such as bio-gas, wind, river flow and solar. The research has begun by surveying works, including the workshop results, water sampling and quality analysis, selection of water source alternatives, and design drawings of water supply and power application alternatives. In My Phung Hamlet’s drinking water supply plant, water input for the plant is taken by a deep groundwater well and the power for the pump supplied partly by solar energy combined electricity grid system. Finally, some recommendations after the plant construction and pipelines are given for a future greenhouse-gas emission research and management. It is found that solar energy application is a new approach for local conditions and fitting the purpose of CDM objectives. However, the cost of solar panels is still high that leads to a limitation for the implementation if the financial is shortage.
