What is OTEC?
The Basics of Ocean Thermal Energy Conversion
Ocean Thermal Energy Conversion (OTEC) is a process that uses the temperature difference between the warm surface waters of the ocean and the cold deep waters to generate electricity. It’s a promising renewable energy source that leverages the immense heat stored in the ocean.
How Does OTEC Work?
OTEC systems typically operate using the following principle:
- Warm Surface Water: This is used to vaporize a working fluid with a low boiling point.
- Turbine: The vaporized fluid drives a turbine connected to a generator.
- Cold Deep Water: This condenses the vapor back into a liquid, and the cycle repeats.
