Converting energy from ocean currents

Abstract

Ocean energy can be harnessed in different ways. One of those ways is the kinetic energy in water flows. This form of energy is present in ocean currents and tidal streams created when water is forced to flow between coastal barriers. This form of energy corresponds to a significant portion of total energy present in the oceans and very interesting features it presents better predictability and less variability over time, compared with other forms of energy. This article reviews the main settings available to convert energy from currents and discusses some projects in various stages of development.
