The world’s oceans are a vast source of natural wave energy. At Global Re-Energy we harness the energy from ocean waves and convert it into electricity. Since the ocean’s cover 70% of the earth’s surface, wave power is abundant all around the globe. It’s an environmentally safe, cost-effective and reliable source of energy that is beneficial to electrical applications throughout the world.
Types of Ocean Energy
Wave Energy: Wave Energy is a form of kinetic energy that is used to power a turbine. Wave energy is captured directly from the waves of the ocean’s surface. A wave energy turbine is chosen on weather conditions for hydroelectric power stations. Wave energy is growing increasingly popular in northern Canada, Scotland, Southern Africa, and Norway amongst others.
Tidal Energy: Tidal energy uses the movement of the ocean’s water currents. It also uses the rise and the fall of tides to create electricity. Tidal energy uses generators below the surface that produce high tidal movements. They capture the kinetic motion of ebb and flow of ocean tides and use them to generate electricity. An upside to tidal energy is that while waves can be unpredictable we have extensive studies with the world’s tidal pulls. Tidal energy is growing in popularity. This renewable energy doesn’t disappear and produce zero greenhouse gas emissions.
Thermal Energy: Ocean thermal energy uses the different temperatures from the ocean’s surface to its depths. The bigger the difference in temperature the more effective it becomes. There are three types of ocean thermal energy cycles.
- Closed Cycle: These systems use warm water of the water’s surface to vaporize fluid Amonia, which has a low boiling point, to turn a turbine to activate a generator to produce electricity.
- Open Cycle: This system utilizes the oceans warm surface by placing the water in a low pressure container. The water then boils producing steam. The steam travels through turbines that begin to turn. The turbines are connected to an electrical generator that then produces electricity. The steam is then converted back to liquid state by exposing it to cold temperatures deeper into the ocean.
- Hybrid Systems: These systems are a mix of both the closed and open cycle systems. The warm ocean surface is pumped through a heat exchanger and into a vacuum chamber. The water is heated and evaporates creating steam. The steam then vaporizes Amonia that turns the turbines and creates electricity.
