Tidal Energy

The “Tidal energy” has been a kind related to power that is basically generated from water. In this regard, tides are usually utilised while generating power like electricity.

Introduction 

Energy that is generated from using the associated rise and followed by falls in the case of tides in the respective oceans and/or current is known as tidal energy. Additionally technologies such as the turbines along with paddies are usually seen being utilised while generating the same energy. Although, due to comparatively higher expense, in India, the same energy is not being used in sectors that are commercial; however, distinct projects such as “Gulf of Kutch”, “Durgaduani Tidal Power Project” etc had been taken.

Discussion 

Tidal power plant

  • Any given plant while harnessing energy from tides usually requires numerous turbines that usually are equipped with “blades”.
  • Around 18 rotations each minute while relying on associated strength of currents and/or tides are made by the same blades.
  • Lastly, as the involved turbines remain in connection with “gearboxes”, and rotation of the same blades via the “gearboxes” usually switches the flows that are of the tides’ towards required electricity.
  • The dam and/or barrages have also been involved while producing powers from tides but in this scenario, generally the power has been seen as harnessed from numerous rivers that are counted as tidal.

Projects for tidal plants in India

  • Related estimation has suggested that across India the identified potential of “tidal energy” in this nation has been around 12455 Megawatts. 
  • The MNRE(Ministry of New and Renewable Energy)  has identified two distinct areas that have required potential while producing around 3.75 Megawatts in West Bengal and the other one has been in Gujarat with related potential regarding production for the same energy by around 50 Megawatts. 
  • The cost associated with “Durgaduani Tidal Power Project” has been estimated at around 238 crore INR. This has projected that around 63.50 crore INR has been required for an individual Megawatt. On the other hand the “Gulf of Kutch project” has shown the similar expense and has been comparatively higher, almost around 750 crore INR. In this scenario, around fifteen crore INR is required to be invested while cultivating 1 Megawatt. 
  • Unfortunately, due to projected estimation being comparatively higher, the aforementioned projects have been declined. However, required “Research and Development” regarding the same energy is seen as undergoing by respective authorities across the nation.

Other tidal energy plant

  • According to data, the other kind related to “tidal energy” has been the utilisation of barrages. Usually barrages are seen as being established across numerous rivers that typically have comparatively higher tides.  
  • The “Damodar Valley Corporation” has been operating onwards from 1953 and is generating required power that is harnessed from tides of Damodar River. Along with the same, the “DVC” has been operating on another river known as “Konar”. Four distinct dams have been allocated and known as “Tilaiya”, “Maithon” operating on “Barakar”. The dam identified as Panchet is harnessing required power from “Damodar”. Lastly, the dam known as Konar is operating on a river known as Konar.
  • Examples regarding the related efficiency of the “DVC” can be highlighted. The “Maithon hydel station” has been producing around 63.2 units of “Megawatts” while combining the three distinct units that have been installed in this regard. The “Panchet Hydel Station” has been generating comparatively higher megawatts than the prior. This individual plant has been producing around “80 Megawatts” while utilising two units.   
  • Another similar plant, in this regard can be highlighted that is placed in the state of the same nation and known as Uttarakhand. The same has been known as “Tehri Hydropower Complex” and is also considered while ranking as the highest. This plant, in particular, has been able to produce power from required tides by around “2400 Megawatts”.

Conclusion

It can be concluded as the “tidal energy” has been renewable and usually generated utilising tides. In India, numerous similar projects have been considered but due to the price regarding the same being comparatively higher, those have been dropped. However, data also have been suggesting the required “R&D” have been undergoing regarding this.
