EXTRACT ENERGY FOR EVERYONE

Global wave and tidal energy potentialThe ocean is a vast source of energy, and this energy can be exploited from thermal gradients, salinity gradients,tidal ranges, tidal currents, and waves (OES, 2011).

The global theoretical potential of wave power estimated at 29,500 TWh/year (OES, 2011).

Figure 2: World map of tidal range (OES, 2011).

Wave energyEnergy available at the ocean surface

Tidal energyEnergy available in the rise and fall of water level during high and low tides.

Categories of Devices proposed or under development for capturing energy from waves :

AttenuatorsOvertopping devicesOscillating water columnsPoint absorbersOscillating wave surge converters

Overview of available technologies for converting wave and tidal stream energy into electricity

Wave energy device types

Tidal stream device types

Indian ScenarioOur coastline is 7,517 km in length

Average wave power potential is 50 kW/m.

Potential Tidal power regions are Gulf of Khambhat, Gulf of Kutch and Gangetic Delta

Power potential in above area is of the order of 8000 MW

India will need 3400 TWh of electricity annually by 2070.

Despite the huge potential, India has no policy on tidal energy.

Tidal energy is not cost competitive

Economically feasibility is important inselecting a spot to set up a tidal energystation.

Setting up tidal facility costs Rs 25 crore for50 MW, not including maintenance andrunning costs.

This is far more expensive than coal and oil.

Our Vision is to produce sustainable, clean and reliable energy for the Indian market.

An uncompromising respect for our environment

To involve local communities as active participants.

Develop a device to generate power from 3kw-30 kw .

Capital cost equaling to diesel generators

Evolve smart grids to reduce transmission loss

Delivering energy solutions which are sustainable and economically viable for

sea side settlements (fisheries),seaside resorts, harbour lighting,desalination units, cold storage etc.

PNEUMATIC SYSTEM

HYDRAULIC SYSTEM

Basic power calculations supporting the idea:Sea waves are random in nature. The power available in random sea is expressed asP=H²T kwm¯¹Where -H is the average height of the wave crest T is the zero crossing periods in second

Available power with 0.5 m height wave is 2 kwm¯¹ . Ideally if the device can generate electricity somewhere from 2kw/h-15kw/h. The efficiency of the generator depends on the air compressing unit, capacity of the pressure tank and the rate at which the compressed air is converted in to electricity using appropriate generator.
