EMEC trials for Nautricity device
A Glasgow-based renewable energy company has deployed a tidal turbine for testing in Orkney waters.
Nautricity's Contra Rotating Marine Turbine (CoRMaT) is undergoing trials at the European Marine Energy Centre's Shapinsay Sound site.
Over the past 18 months, the Strathclyde University spin-out company has built its first commercial scale device which, with a rotor span of 10 metres, is significantly larger than early test models.
With the help of a £250,000 Smart Scotland grant from Scottish Enterprise, Nautricity has developed and patented a unique morring system called HydroBuoy. This is designed to ensure that CoRMaT devices remain steady in strong currents and is also being tested as part of the deployment.
Cameron Johnstone, the tidal energy company’s co-founder and chief executive officer, said testing the device at full-scale in real-life conditions was an important step forward that would produce valuable data to allow the company to proceed to full commercial deployment.
"Once we have demonstrated the technology here and shown that it can provide affordable electricity, we will then build out to multi-megawatt arrays at home and overseas," he said.
"In order to be able to compete abroad in the future, it’s essential that we have a robust, indigenous market from which to launch our international business development.
“We believe we are doing all of the right things in developing lower cost, next-generation technology, through our progressive testing programme and gathering the data to ensure that we are taking to market a product that works and can compete with other forms of energy generation."
CoRMaT is designed to be light and compact to reduce engineering and deployment costs. It is tethered to the seabed and held in position by a sub-surface float.
