Hybrid heads for second try

The Skwid will be tested off Karatsu, on the southern island of Kyushu

The Skwid

Offshore oil contracting giant Modec remains on course to grid-connect its trail-blazing Skwid hybrid wind-marine energy concept by next September, alleviating fears that the project might be massively delayed after part of the unit was lost at sea off the coast of Kita-Kyushu city during a first installation attempt this autumn.

The Tokyo-based company has been angling to test the full-scale prototype –  which mates a three-bladed vertical axis Darrieus turbine with a Savonious ocean current device  –  in 50 metres of water off Karatsu, in Saga prefecture, and start selling produced electricity to regional utilty Kyushu Electric later next year.

The slimline unit, foreseen for powering remote islands, is calculated to have an ouput capacity of 500kW in winds of 13 metres per second (m/s), rising toward 1MW in velocities of 16m/s.

Original deployment plans were scuppered after the ocean current turbine Log in to read complete article.
