Harnessing the Potential of Tidal Currents in Indus Delta Creeks for Making Sustainable and Green Pakistan

Abstract

Abstract- Pakistan is facing serious energy crises. Presently the energy supplies are primarily fulfilled by natural gas and imported oil. The energy deficit is a major constraint to economic growth. However, Pakistan is blessed with natural resources, which can be utilized to tackle the energy deficit. Compared to other enewable energy technologies, tidal energy is still not capitalized in Pakistan. It was estimated that around 900 MW power can be generated from tidal currents in the Indus Delta Creek areas. Among all creeks Chan Waddo, Korangi, Paitiani, Kajhar and Khai creeks have the highest power potentials. In this study, a GIS based approach was used to analysee the sustainable use of the estimated tidal current power potential. The proximity of power potential sites to power grid, urban area, built up land and road etwork for easy access demonstrate the sustainable use ofthis energy. Results showed that energy generated at hese potential sites can be utilized in many ways as Korangi creek, Chann Waddo creek and Phitti are close to Karachi, while there are several towns in the vicinity of Pitiani creek and Khai creek. Other potential sites are close to the planned city Zulfikarabad. As the tidal current potential of the Indus delta creek system is encouraging, it can be considered in future energy policies and sustainable development strategies for a green and sustainable Pakistan. Therefore, it is highly recommended that further research and pilot projects should be commenced on prioritybasis.
