Carnegie Clean Energy Limited

Carnegie is the 100% owner and developer of the CETO Wave Energy Technology that converts ocean swell into zero-emission renewable power and desalinated freshwater. Over $140m has been invested to fund the development of the CETO technology. Carnegie employs a combination of rapid prototyping, computational simulation, wave tank testing and, in-ocean testing in developing CETO.

CETO is designed to be the simplest and most robust wave technology globally and, after 10 years of continuous development, and tens of thousands of in-ocean operational hours of testing is now nearing the end of its commercialisation phase with the development and delivery of its CETO 6 product generation.

The CETO 6 Wave Hub Project is Carnegie’s first international CETO project and will be located at the world class Wave Hub facility in Cornwall, south west England. The Project will be delivered in 2 stages, the first focused on the implementation of a 1MW CETO 6 unit to be followed by stage 2 a 15MW commercial array, at the same site, which will offer a commercial return on investment. The Project design and development commenced in 2016, with stage 1 commissioning currently targeting the end of 2018, to be followed by 12 months of operation.

In late 2016, Carnegie was granted £9,551,962 (AUD$15.5m) from the European Regional Development Fund to support the first stage of the project. The £9,551,962 grant is part of the European Structural and Investment Funds Growth Programme 2014-2020, and forms 65% of the funding for stage 1. Stage 1 consists of a £14.7m project to design, construct, install and operate a single 1MW grid-connected CETO 6 wave energy converter device. This unit will be adapted to local conditions and industrialised for large scale commercial deployment at the purpose built, Wave Hub test site.

CETO 6 offers a higher rated capacity and increased efficiency than previous CETO generations which, when deployed in large commercial arrays, will deliver a levelised cost of energy (LCOE) competitive with offshore wind. Longer term development will continue to push costs lower below this benchmark. It is this technology that will be utilised, developed and adapted for deployment in Cornwall.

The Project will be delivered by Carnegie’s local subsidiary, CWE UK, based at the Hayle Marine Renewable Business Park, with commercial and technical support from its Australian parent company and developer of the CETO wave energy technology, Carnegie Wave Energy. Delivery of the Project will leverage Cornwall’s, and the UK’s, exceptional wave energy resource, marine energy revenue support, maritime industrial heritage, the world class Wave Hub infrastructure, and active and innovative marine engineering and research sectors. Carnegie also expects to utilise the marine energy feed in tariff available in the UK which equates to an estimated £305/MWh for the second stage of the Project.

Deployment and operation of the CETO device will be within a defined berth, awarded to Carnegie in 2014, at Wave Hub. Wave Hub is a facility for testing of wave energy device arrays. It provides a fully grid-connected and consented wave energy site, located approximately 10 nautical miles (16km) off the north coast of Cornwall. The Wave Hub Offshore Deployment Area, which covers 8 km² of seabed, is divided into four separate berths available to lease to wave energy device developers, with a 30MVA grid connection agreement.

The Project will also include engagement with and coordination of a suitable supply chain for the construction and operational phases. The successful demonstration of this Project will present a significant opportunity to commercialise wave energy in the UK through bridging the gap between technology readiness and commercialisation.
