NoviOcean’s wave power technology, developed over several years, has been tested in wave pools and a real environment near Stockholm. A small version powers homes on Svanholmen island, proving the concept works at sea.
On one square kilometer, 15 wave power plants can generate 15 MW, compared to offshore wind’s 10 MW. Combined, they can produce 25 MW, sharing the costs of the sea area and transmission cable.
According to the firm, the hybrid approach delivers more consistent energy, as waves generate power for days after the wind subsides. Additionally, wave plants can be placed closer to shore without visually disturbing the coastline.
I speculate that this balanced out by the fact that a single one of these can more easily connect to the power grid and are more efficient to deploy and maintain in large quantities.
You could place these almost anywhere and they will generate something.
Yea, but I would imagine the upkeep and maintenance on these, especially due to being in salt water, is higher than it needs to be. Simple is generally better for these things.
