Renewable energy can be produced by using kinetic energy of the flowing water such as rivers, ocean currents and tidal flows. The kinetic energy can be transformed to the power by hydrokinetic turbines. There are many different designs of hydrokinetic turbines for tidal applications, rivers and pipe. The working principle of the hydrokinetic turbines are similar with wind turbines. In this study, hydrokinetic turbine technology have been reviewed. Furthermore, turbines have been compared according to their working principle which are vertical and horizontal, and according to operating conditions such as open channel and pipeline. The hydrokinetic turbine in pipe is more predictable and environment friendly. This system can generate electric independent from nature because of closed system. It means that the velocity and discharge of the water can regulate manually. Another advantage of the hydrokinetic turbines is that, it can take replacement of the pressure breaker valves on the water supply network systems to produce power. Energy can be generated while pressure is reducing in the water distribution system. Moreover, Gorlov turbine is placed in the pipe than it is analysed by ANSYS Fluent software. Results indicates that, this new technology can be used in water distribution systems with pipes. But optimizing is needed to create more efficiency power.
