Australian wave technology developer Carnegie Clean Energy has upgraded the power rating of its Ceto 6 device to 1.5MW from 1MW following a redesign.

The Western Australia (WA) outfit said the new iteration of its next-generation point absorber would feature multiple moorings instead of a single mooring.


Multiple moorings increase the amount of power that can be absorbed by a wave device as a result of capturing energy in vertical, horizontal and rotational motions, it added.

The uprated Ceto 6 will feature at its Albany Wave Energy Project in WA, which is due to be installed in 2019.

Carnegie chief technology officer Jonathan Fievez said: “We challenged the Ceto team to disrupt our own thinking and used collaborations with industry as well as taking our own internal analysis capabilities to go to the next level.

“We are very confident in the performance trajectory that we are taking with the updated Ceto 6 design.”

Carnegie said multiple moorings also require multiple foundations for each unit, which could potentially increase the cost of foundations per unit.

Each of the mooring lines and associated foundations in the new design are carrying less load and can therefore be smaller than the foundation for a single moored device, it added.
