Question

How energy is produced in OTE plants??????? ​

Answer 1

Answer:

Ocean Thermal Energy Conversion (OTEC) is a process that can produce electricity by using the temperature difference between deep cold ocean water and warm tropical surface waters. OTEC plants pump large quantities of deep cold seawater and surface seawater to run a power cycle and produce electricity.

Answer 2

Answer:

OTEC uses the ocean's warm surface water with a temperature of around 25°C (77°F) to vaporize a working fluid, which has a low-boiling point, such as ammonia. The vapor expands and spins a turbine coupled to a generator to produce electricity.

A 10MW ocean thermal energy conversion (OTEC) prototype power plant has been planned off the coast of Hainan Island in southern China. The OTEC technology uses the temperature difference between the cold water in the deep sea (5°C) and the warm surface seawater (25°C) to generate clean, renewable electricity.

OTEC uses the principle of a heat engine. It works by converting a temperature difference into energy. This means the difference in temperature between the warmer water on the surface and the cooler water in the depths of the ocean can be converted into electricity.

Ocean thermal energy conversion (OTEC) uses the temperature difference between cooler deep and warmer shallow or surface seawaters to run a heat engine and produce useful work, usually in the form of electricity. OTEC can operate with a very high capacity factor and so can operate in base load mode.

How does ocean thermal energy generate electricity?

First, the pipe flows through a heat exchanger fixed in the hot surface waters of the ocean, which makes the ammonia boil and vaporize. The heated ammonia vapor expands and blows through a turbine, which extracts some of its energy, driving a generator to produce electricity.

What is the ultimate source of the energy generated by OTEC?

Ocean Thermal Energy Conversion technology, known as OTEC, uses the ocean's natural thermal gradient to generate power.
