The islands turning the tide electric


Orkney, a remote archipelago off the north coast of Scotland, is harnessing the power of its tides. Completely surrounded by ocean and continuously battered by waves up to 13m (43ft) high, the residents of the islands are now finding a new way to work with the waves.

It’s the perfect location to test out new, renewable energy solutions, such as wind, wave and tidal energy. To do so, a floating tidal turbine draws energy from the movement of the sea, and then converts it to electricity.

“The principle behind it is much like wind turbines on land. In a wind turbine, the blades are being moved by the wind, whereas in our tidal turbine this sea water is moving blades and turning that into electricity through conventional generators,” explains Daniel Wise from Orbital Marine Power.

In one year, this turbine produced enough energy to power roughly 830 UK households.

One way that Orkney is dealing with this massive production of renewable energy is converting it into hydrogen, which is much more easily stored.
