The Future of Clean, Renewable Ocean Power
Ocean Thermal Energy Conversion (OTEC) utilizes the natural temperature gradient of tropical oceans to produce electricity, desalinated water, and support sustainable marine operations.
Uses a working fluid with a low boiling point that vaporizes from warm seawater, drives a turbine, then condenses using cold deep water.
Directly uses warm seawater in a low-pressure container, where it flashes into steam to drive turbines, then condenses with cold water.
Combines elements of both closed and open cycles for enhanced efficiency.
Recent breakthroughs in OTEC technology include enhanced heat exchangers, deep water pipe technology, and modular floating platforms.
OTEC has a theoretical potential of 3-5 terawatts globally, providing baseload power 24/7 with zero carbon emissions.
Key challenges include high initial costs, efficiency limitations, and environmental considerations.
