Wave & Tidal Energy Gains Momentum, Showing Significant Potential
The wave and tidal energy sector is gaining momentum, with diverse designs and applications in development worldwide. Despite being in its infancy, this renewable energy source shows great potential, with the U.S. Department of Energy investing $23 million in new projects.
Wave energy technologies range from mechanical jellyfish-like converters to wave-powered desalination systems. While the industry faces challenges like technological uncertainties and financing hurdles, its potential is significant. Marine hydropower could provide up to 10 percent of the world's electricity, according to the World Energy Council.
In the U.S., wave energy could power over 5 million homes and create around 33,000 jobs. However, currently, there are no specific companies actively developing seawater power plants. Most U.S. efforts focus on tidal and wave energy. Notable international projects include the MeyGen tidal energy farm in Scotland, aiming to generate nearly 400 megawatts of electricity.
Technical challenges include the harsh ocean environment, biofouling, and the need for multi-parametric optimization. The impact of tidal and wave energy on marine ecosystems also requires further study.
The U.S. Department of Energy is committed to advancing wave and tidal energy, with plans to develop a full-scale, grid-connected marine test facility off the coast of Newport, Oregon. Despite the challenges, this renewable energy source holds promise for a cleaner, more sustainable future.
