Carnegie takes final Wave Hub berth

Australia's Carnegie Wave Energy has signed a lease for a berth at Wave Hub to fine-tune a 3MW array of its Ceto 6 devices in the run-up to commercial roll-out.

Carnegie, which is building a grid-connected three-unit development in Western Australia using its fifth-generation wave-energy converter (WEC) for switch-on this year, aims to deploy the trio of the devices underwater at WaveHub, off Cornwall, southwest England, in 2016, with plans to build out to a 10MW installation later.

“Securing a berth at Wave Hub provides Carnegie with a pre-developed site and installed grid-connected infrastructure to test the Ceto 6 commercial generation technology while leveraging off UK technical and commercial supply chain expertise in the heart of the marine renewables industry," says Carnegie’s executive director of European business development, Kieran O’Brien.

The Ceto is a fully submerged buoy-and-tether device that produces high-pressure water from the power of waves and uses it to turn an onshore turbine to generate electricity. Ceto 6s will have four times the generating capacity of the previous model.

Waved Hub managing director Claire Gibson notes: “We have seen an increase in demand from companies with advanced wave-energy technology and have had to consider each of them carefully, given we only had one berth remaining. [Carnegie] expects Ceto 6 to be a commercial breakthrough."

Carnegie will occupy the last of fourth berths at Wave Hub, a government-owned 30MW "socket" on the seabed linked to the UK grid by a 16km-long underwater cable. 

The other berth-holders are British outfit Seatricity, which plans to install a WEC this spring before building out a 10MW demonstrator in the next two years; Finnish multinational utility Fortum, which will be trialling a 10MW array with a soon-to-be-confirmed wave technology; and the UK Energy Technologies Institute, which aims to deploy a 6MW offshore floating wind prototype "as early as next year" with partners Alstom and Glosten Associates.
