What are Ocean Currents?
Ocean currents are the movement of water in the ocean, driven by wind, tides, and the Coriolis force. In the open ocean, currents can reach speeds of up to 5 knots, making them a significant source of renewable energy. Ocean current energy harnesses this power by using underwater turbines or other devices to capture the kinetic energy of the currents.

How Does it Work?
The process of harnessing ocean current energy is relatively straightforward. Here’s a simplified overview:
1. Device installation: Underwater turbines or other devices are installed in strategic locations, typically in areas with high current velocities.
2. Energy capture: As the ocean currents flow through the device, they cause the turbine or mechanism to rotate, generating electricity.
3. Power transmission: The electricity is transmitted to the shore via underwater cables, where it can be fed into the grid.
The Benefits of Ocean Current Energy
Ocean current energy offers several advantages over traditional renewable energy sources:
1. Predictability: Ocean currents are highly predictable, allowing for efficient energy forecasting and scheduling.
2. Scalability: Ocean current energy can be deployed at various scales, from small, local projects to large, utility-scale installations.
3. Environmental benefits: Ocean current energy is a clean and silent source of power, with minimal visual impact and no greenhouse gas emissions.
Case Study: MeyGen Tidal Array, Scotland
The MeyGen Tidal Array, located off the coast of Scotland, is one of the largest tidal energy projects in the world. Developed by MeyGen Ltd, the array consists of 269 tidal turbines, generating enough electricity to power over 175,000 homes. The project demonstrates the feasibility and scalability of ocean current energy in real-world applications.
Top 5 Ocean Current Energy Innovations to Watch
