A new tidal power device will be located west of the island of Eday. Using the surplus from the existing onshore wind turbine owned by the Eday Renewable Energy trust, a 500kW electrolyser will generate hydrogen by ‘splitting’ water. Then the hydrogen will be stored as compressed gas and taken to Kirkwall to power a fuel cell there.

This is a way of storing energy so that it can be used on demand. Orkney already produces more power than it can use so this makes a lot of sense and if further developed will avoid the wasteful current practice of ‘curtailment’ where turbines are often switched off.

I’ve already written about this technology at:

Suddenly there’s a brilliant alternative to oil rig decommissioning costs. You can store Scotland’s surplus renewable electricity with it and it’s low-tech.
