Marine energy conversion systems harness renewable power from the natural movement of water, including waves, tides, and currents, as well as from temperature differences in water through ocean thermal energy conversion. Recent advancements include the establishment of a technical committee in India to promote standardization in this field. Marine energy has several advantages, including being a renewable source, environmentally friendly, accessible near coastal areas, and having high energy potential. However, it faces challenges such as potential environmental impact, high costs, location dependency, and technological hurdles in durability. The way forward includes innovative designs like the variable-geometry, oscillating, surge wave energy converter developed by NREL, which is more adaptable and cost-effective, and initiatives for wider deployment in the industry.
