National Institute of Ocean Technology has set up a demonstative 150 KW tidal power plant in Trivandrum in Kerala. The institute has also set up a wave energy project of 75 KW
Tidal Power can be harnessed two ways ? one as through utilizing movement of waves through tidal stream turbine and another through tidal rise by storing water in tidal barrages in ocean which occur daily along the coast. Of this tidal barrage based power generation has been successful in the world. Apart from these two, there are other forms of ocean energy which includes utilizing ocean currents, absorbing subtle movement of waves by buoyant moored devices. Many other technologies are under experimentation across the globe with very few achieving commercial scale of power generation.
Across the globe, Shiwa Lake Tidal plant of South Korea and La Rance Tidal power plant of France are larger ones with generation capacity of 250 MW. Of this French tidal power plant is in operation for more
Aqua Dynamo - new tidal turbine designed by a Canadian entrepreneur to harness the kinetic energy found in moving bodies of water could be ideal for India to generate clean energy from a renewable resource with less cost and a smaller carbon footprint. The Aqua Dynamo's turbines include a powerful blade that is designed to be hydrodynamic. This means that the turbines can harness the kinetic energy found in moving bodies of water. These turbines generate enough clean energy to power over three million homes while taking up only 200 acres or less of water space. The current cost of constructing tidal turbines that are able to generate 3000 MW is approximately $3 billion
Tidal Power, a form of hydropower offers potential in India with advancement in technology.
Recent developments and improvements, both in design (e.g. dynamic tidal power, tidal lagoons) and turbine technology (e.g. new axial turbines, cross flow turbines), indicate that the total availability of tidal power may be much higher than previously assumed, and that economic and environmental costs may be brought down to competitive levels.
Urja Global has signed an MoU with Gujarat government to set up a tidal power project with a capacity of 10 MW. Gujarat Power Corp Ltd has also plans to set up a 200 MW tidal power plant in Kutch. These projects are awaiting environmental clearance. Several studies estimates tidal energy potential at 7000 MW in India. Currently, government of India do not h
