Marine Energy Projects Harness Ocean Currents, Tides, and Waves for Renewable Power
Three innovative marine energy projects demonstrate the potential of ocean currents, tides, and waves for renewable power. Japan's Kairyu turbine generated 100 kW from the consistent Kuroshio Current in 2017, while New York City's Roosevelt Island Tidal Energy Project produced a U.S. record 210 MWh from tidal currents in 2020. Scotland's Penguin wave energy converter operated for two years amid harsh seas before sinking, providing insights for future designs. Despite promising results, high costs and engineering challenges remain barriers to wider adoption.
