Prototype expected to be commercially available by the end of 2018

The world’s largest tidal turbine has achieved its full export capacity of 2MW, as rated by the European Marine Energy Centre (EMEC) in Scotland.

The SR2000 prototype, which was designed by Scotrenewables, was connected to the Orkney grid via undersea cable and operated by a small crew using locally-based workboats.

After energisation, it underwent a phase-testing programme before reaching its peak rating.

EMEC managing director, Neil Kermode, praised the achievement and said: “Tidal energy is getting ever closer to becoming part of our carbon-free energy mix.”

Scotrenewables has been focused on improving the SR2000’s output since it was originally launched in May 2016.

The 64-metre vessel harnesses tidal power via a submerged propeller, which designers say can be optimised to suit different tidal conditions.

Founder and director, Barry Johnston said: “After developing the initial concept more than a decade ago, it’s fantastic to now see the latest evolution.”

The project has been supported by Scottish Enterprise’s WATERS II, and received investment from the Scottish Government, via the Renewable Energy Investment Fund.

Scotrenewables were also recently selected by the European Commission to lead the FloTec project, an industrial consortium which seeks to make optimised SR2000 technology commercially available by the end of 2018.
