(The 254 megawatt Sihwa Tidal Power Plant in South Korea is the largest tidal power plant yet built.)
There’s been a lot of talk about using tidal power to generate renewable energy, but so far not much has been built on a large scale. But in China, a consortium of eight dutch companies and the Chinese government are trying to move the technology forward by building an enormous 40 to 60 mile tidal hydroelectric dam. They’ve satisfied themselves that the idea is sound, and they’ve started economic studies for their plan to build a truly massive tidal power plant. As currently conceived, it would use 4,000 turbines to put out 15 gigawatts of power.
The economic study should be completed this year. If all goes well, they’ll move on to testing and finalizing the design. The backers hope to have the project built by 2020.
