Economic benefits from spin out company, Nautricity Ltd, and adoption of new technology to extract energy from tidal flows.

Narrative

A step change reduction in tidal energy costs has been achieved through the development of the novel Contra Rotating Marine Turbine ‘CoRMaT’ tidal energy technology. The internationally patent-protected CoRMaT system reduces capital, operational and maintenance costs while increasing the extractable tidal energy resource by harnessing flows in deeper waters and from less energetic sites, which were previously considered to be uneconomic. A University spin-out company, Nautricity Ltd, was formed in 2010 to commercialise this technology. The development of this technology has changed both Scottish and UK Government policy via their introduction of programmes which demonstrate a step change reduction in the costs of marine renewables.
