Scotland-based ocean energy developer Aquamarine Power Ltd. announced it will cease development of its Neptune tidal stream generator in order to focus fully on its Oyster wave energy converter.
In March, Aquamarine named marine constructor Fugro Seacore to install its Oyster wave energy converter at the European Marine Energy Center (EMEC) at Orkney, Scotland. (HNN 3/26/09) Under a 2 million pound (US$2.9 million) contract, Fugro Seacore is to install the wave energy generator on the seabed at the EMEC testing site during summer 2009, with completion planned in the fall.
�Further development of Neptune, Aquamarine’s tidal stream device, will cease,� the company said. �The design and intellectual property created as part of the Neptune project will continue to be part of the company’s product pipeline but will not undergo further development.�
Aquamarine said it will continue to develop tidal sites on a technology-neutral basis with utility partners.
The Oyster unit is designed to capture energy from amplified surge forces in near-shore waves. The system includes an oscillating wave surge converter, or pump, fitted with double-acting water pistons. Each passing wave activates the pump, delivering high-pressure water by pipeline to shore where it powers conventional hydroelectric generators.
