There are three categories of tidal energy technologies. The first category, tidal range technologies use a barrage - a dam or other barrier - to harvest power from the height difference between high and low tide. The power is generated through tidal turbines (most of them come from hydropower design, such as bulb turbines) located in the barrage, and their commercial feasibility has been well established through the operation of plants in France Canada China and Russia from the 1960s and 1970s. In 2011/2012, South Korea opened the largest and newest tidal barrage (254 MW). The second category, tidal current or tidal stream technologies have had more than 40 new devices introduced between the period 2006-2013. The final category, hybrid applications are forms of tidal range technologies that have great potential if their design and deployment can be combined with the planning and design of new infrastructure for coastal zones.
