IIT Madras generates power from sea waves
IIT Madras researchers have developed an ocean wave energy converter system, named Sindhuja-I, to generate electricity from sea waves. The product’s name, Sindhuja-I, means “created from the ocean” in Sanskrit. Successful trials were conducted off the Thoothukudi coast of Tuticorin, Tamil Nadu, at a location with a depth of 20 metres. Researchers expect to commercialize the innovation by 2024.
The system has a floating buoy, a spar, and an electrical module and the buoy moves up and down as the wave moves up and down. In the present design, a balloon-like system called a ‘buoy’ has a central hole that allows a long rod called spar to pass through it.
Sindhuja-I can currently produce 100 watts of energy. It will be scaled up to produce one megawatt of energy in the next three years. The device will be deployed in offshore locations that require reliable electricity and communication either by supplying electric power to payloads that are integrated directly in or on the device or located in its vicinity as on the seabed and in the water column. The targeted stakeholders are the oil and gas, defence and security installations and communication sectors.
Many countries and companies globally have done this before. Nations like the US, UK and Israel are generating energy through this route. However, this is for the first time that the technology is in the process of being proven in India.
Sindhuja-I, will help the country achieve its climate change-related goals of generating 500 GW of electricity by 2030 through renewable energy. India has a 7,500 km long coastline capable of producing 54 GW of power, satisfying a substantial amount of the country’s energy requirement.
