Marine and hydrokinetic (MHK) power generation is a relatively new type of renewable generation. Predecessors such as wind power generation, hydropower plant generation, geothermal generation, photovoltaic generation, and solar thermal generation have gained a lot of attention because of their successful implementation. The successful integration of renewable generation into the electric power grid has energized global power system communities to take the lessons learned, innovations, 268and market structure to focus on the large potential of MHK to also contribute to the pool of renewable energy generation.

This chapter covers the broad spectrum of MHK generation. The state-of-the-art power take-off methods is discussed. The types of electrical generators and the options for implementation are presented.
