Study of Utilization Under Sea-water Hydrostatic Pressure as Hydro Power Generation

Abstract

Harvesting energy from hydrostatic pressures in the ocean depth involves many variables that create complex situations. Variables such as pressure, temperature, water flow, and even fish are examples of variables that must be taken into account. In this study, the variables used to estimate power generation are pressure and depth. The purpose of this research is to get the picture of power potential that can be obtained by utilizing hydrostatic pressure under the sea. The study is base on literature from previous research and calculation. The generator is assume coupled with reverse osmosis equiptment so that the output is fresh water and electricity. The calculation base on information of population in Pramuka island that required 288 m3/day. The results show that the power generated is 16% of the available power potential and save electricity cost of water distribution 913 Rp/m3 or reduced 46%.
