Surf ‘n’ Turf: Innovative new tidal power generation for Orkney



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.

    Good morning Professor Robertson! I hope you are keeping well. Thank you very much for all the great work you do in researching and publicising good news about Scotland. I pass on the good news whenever I can. You are creating an excellent information bank for the next push for independence for Scotland. Thanks again, and best wishes to you.
