Ocean Thermal Energy Conversion (OTEC) is a marine renewable energy technology that harnesses the solar energy absorbed by the oceans to generate electric power.

Summary edit

Description
English: Ocean thermal energy conversion (OTEC) is a process or technology for producing energy by harnessing the temperature differences (thermal gradients) between ocean surface waters and deep ocean waters.

Energy from the sun heats the surface water of the ocean. In tropical regions, surface water can be much warmer than deep water. This temperature difference can be used to produce electricity and to desalinate ocean water. Ocean Thermal Energy Conversion (OTEC) systems use a temperature difference (of at least 25° Celcius or 77° Fahrenheit) to power a turbine to produce electricity.

Warm surface water is pumped through an evaporator containing a working fluid. The vaporized fluid drives a turbine/generator. The vaporized fluid is turned back to a liquid in a condenser cooled with cold ocean water pumped from deeper in the ocean. OTEC systems using seawater as the working fluid can use the condensed water to produce desalinated water.

Français : La conversion de l'énergie thermique des océans (OTEC) est un processus qui peut produire de l'électricité en utilisant la différence de température entre les eaux océaniques froides profondes et les eaux de surface tropicales chaudes. Les usines OTEC pompent de grandes quantités d'eau de mer froide profonde et d'eau de mer de surface pour exécuter un cycle d'alimentation et produire de l'électricité.

L'énergie solaire chauffe l'eau de surface de l'océan qui est alors plus chaude que l'eau profonde. Cette différence de température peut être utilisée pour produire de l'électricité et dessaler l'eau de l'océan. Les systèmes de conversion d'énergie thermique océanique utilisent une différence de température (d'au moins 77° Fahrenheit ou 25° Celcius) pour alimenter une turbine afin de produire de l'électricité. L'eau de surface chaude est pompée à travers un évaporateur contenant un fluide caloporteur. Le fluide vaporisé entraîne une turbine / générateur. Le fluide vaporisé est retourné à l'état liquide dans un condenseur refroidi avec de l'eau froide de l'océan pompée des profondeurs de l'océan.
