Ocean Thermal Energy Conversion (OTEC)
ConceptAbout
Ocean Thermal Energy Conversion (OTEC) is a renewable energy technology that harnesses the temperature difference between the warm surface waters and cold deep waters of the ocean to generate electricity. This process leverages the thermal gradient, typically found in tropical regions, where the temperature difference can be as much as 20 to 25 °C. OTEC systems can operate continuously, providing a reliable source of base-load power. OTEC systems are categorized into closed-cycle and open-cycle designs. Closed-cycle systems use a working fluid like ammonia to drive turbines, while open-cycle systems vaporize seawater directly. OTEC offers additional benefits, including desalination and cold water for air conditioning. Despite its potential, OTEC faces challenges such as low efficiency and high construction costs. However, it remains a promising technology for sustainable energy production in tropical regions.
