IIT Madras Researchers develop ‘Sindhuja’ which generates Electricity from Sea Waves

In News
  • Indian Institute of Technology Madras (IIT Madras) Researchers have developed an 'Ocean Wave Energy Converter' that can generate electricity from sea waves.
Sindhuja-I
  • Sindhuja-I is an ocean wave energy converter that is currently capable of producing 100 watts of electricity using energy from seawaves.
  • Its capacity is expected to be scaled up to 1 mW of energy in the next 3 years.
  • This system has a floating buoy, a spar and an electrical module.
  • The buoy moves up and down as the sea waves oscillate. A hole in the centre of the buoy will allow the spar to pass through it.
  • The spar is fixed to the seafloor so that it is prevented from being moved by sea waves.
  • This ensures that the buoy moves and the spar doesn’t. This results in the production of a relative motion between spar and buoy.
  • The power is produced by an electric generator using the relative motion between the spar and buoy.
Limitations
  • The amount of energy generated from the ocean wave energy converter differs based on the wave height and seasonal changes. While it does not matter if the energy is not produced when the weather is calm, there are concerns regarding the technology’s endurance during rough weather.
  • Therefore, the Sindhuja-I was tested in November 2022 when the India Meteorological Department (IMD) issued a red alert for several districts in Tamil Nadu.
  • The testing revealed that the system was capable of withstanding challenging weather conditions.
