A 180 metre-long wave machine has set sail from Leith in Scotland to Orkney, where it will undergo trials at the European Marine Energy Centre.

The P2 Pelamis 750 KW wave machine was built in Leith for ScottishPower Renewables, part of Spanish energy company Iberdrola, and converts the motion of waves into electricity via hydraulic cylinders.

The P2 Pelamis is part of a cross-industry collaboration with a similar device managed by E.ON, and both will work in tandem at Orkney, allowing the companies to better understand how an array of wave machines would operate.

Alan Mortimer, head of policy at ScottishPower Renewables, said: “The development is a major achievement for the firm. We are delighted to see the Pelamis device going into the water following a lot of hard work. The initial testing has been encouraging, and we look forward to seeing the device working in collaboration with E.ON’s machine in Orkney.”
