Japan has just turned the power of ocean tides into electricity.
Beneath the waters of the Naru Strait near Japan’s Goto Islands, the AR1100 turbine is now generating 1.1 MW of clean energy for homes and businesses.
Built by Proteus Marine Renewables in partnership with Kyuden Mirai Energy, this massive underwater turbine uses three intelligent rotating blades that adjust in real time to capture tidal energy as currents shift direction four times every day.
The electricity travels through subsea cables directly to shore and into the power grid with no battery storage required.
This proves the ocean could become one of the world’s most reliable clean energy sources.
Unlike solar or wind, tidal energy is predictable, steady, and available every single day.
For coastal communities facing rising energy costs, this breakthrough could be game changing.
Japan has now officially certified the system for national grid standards, marking a major step toward a cleaner energy future.
