Clever MIT floating wind turbines can store power for when the wind doesn't blow

Clever MIT floating wind turbines can store power for when the wind doesn't blow

are growing rapidly worldwide, but because the sun doesn't always shine and the wind doesn't always blow, we need to find more ways to store energy. That's a huge challenge, and we'll probably end up using a mix of technologies to reach that goal (for example, grid-scale liquid-metal batteries look promising). A clever new way to do that was invented by MIT researchers, combining both the production of clean energy and - when needed - its storage.At first glance, their system might look like a regular offshore wind farm. But what happens beneath the surface is what makes all the difference. When the wind is blowing and there is demand for electricity in the grid, the turbines act just as any offshore wind turbines would. But when the wind is blowing and there's not enough demand for electricity on the grid to soak up that power, or when there's demand but no wind, that's w...
