The company said it will make the environmental assessment data available to the wider marine energy industry.

The grant, issued under the Carbon Trust’s Entrepreneurs Fast Track Program, comes weeks after TEL announced an £11m funding package for the manufacture and deployment of its 1.2MW DeltaStream device.

DeltaStream, which sits on the sea bed without the need for a positive anchoring system, generates electricity from three separate horizontal axis turbines mounted on a common frame.

TEL development director Chris Williams said the DeltaStream device can combine high efficiency and portability with the crucial advantage of being environmentally benign.
