How do tidal and wave energy systems generate electricity ?
Tidal and wave energy systems are renewable sources of energy that harness the power of ocean movements to generate electricity. These systems work on the principle of converting the kinetic energy present in the tides and waves into electrical energy, which can then be used for various applications. Tidal barrages create a difference in water level between two sides of a barrage, built across an estuary or bay with significant tidal range. As the tide rises, water flows through turbines located within the barrage, generating electricity. When the tide goes out, the process is reversed, with water flowing back through the turbines in the opposite direction, generating additional electricity. Tidal stream systems use underwater turbines placed in areas where tidal currents are strong. Unlike tidal barrages, tidal stream systems do not require large infrastructure and can be deployed in various locations where strong tidal currents exist. Wave Energy Converters (WECs) are devices designed to capture the energy from ocean waves and convert it into electricity. There are several types of WECs, including point absorbers, attenuators, and terminators, each working slightly differently but sharing the same goal of harnessing wave energy.
How efficient are modern tidal and wave energy conversion systems ?
Modern tidal and wave energy conversion systems aim to harness the power of oceanic movements for electricity generation. The efficiency of these systems is a critical factor in determining their viability as significant contributors to the global energy mix. Tidal energy conversion systems operate by capturing the kinetic energy from the rise and fall of tides, while wave energy conversion systems extract energy from the motion of ocean waves. Both tidal and wave energy conversion systems face similar challenges that affect their efficiency, including cost, environmental concerns, and technical hurdles. Continued research, technological advancements, and policy support will be crucial in improving their efficiency and ultimately realizing their potential as significant contributors to our clean energy future.
