How can we produce electricity using currents in ocean?
Asked Saurabh Pathak
Electricty can be generated from ocean through various means, mainly
- Ocean Thermal Energy Devices
- Tidal Energy
- Energy of waves and
- Ocean Currents
The energy extraction from ocean currents is somewhat analogous to energy from winds. (ref http://www.boem.gov/Renewable-Energy-Program/Renewable-Energy-Guide/Ocean-Current-Energy.aspx)
Ocean current technology is still in its early stage of development.
For ocean current energy to be utilized successfully at a commercial scale, a number of engineering and technical challenges need to be addressed, including:
- avoidance of cavitations (bubble formation);
- prevention of marine growth buildup;
- reliability (since maintenance costs are potentially high); and
- corrosion resistance.
