Carnegie to power moored and aquaculture vessels with wave energy

Australian wave technology company Carnegie Clean Energy promises to deliver reliable renewable energy for offshore installations, starting with moored vessels used in the aquaculture industry.

Carnegie, which is best known for its CETO large-scale wave power generators, said on Wednesday it had received funding to install and operate a scale demonstrator of MoorPower technology, off its headquarters in North Fremantle, Western Australia.

The $ 3.4 million project is carried out in collaboration with a consortium of partners including two of Australia’s largest aquaculture companies, Huon Aquaculture and Tassal Group, with funding of $ 1.35 million from Blue Economy Cooperative Research Center, based in Tasmania.

Carnegie says the MoorPower solution is a “spinoff” of the company’s CETO wave energy technology, which includes a submerged buoy that sits a few feet below the ocean’s surface, moving with the waves.

Like the CETO system, MoorPower will use a power take-off (PTO) system that converts the orbital motion of waves into clean electricity. But rather than being a stand-alone buoy system (pictured below), the scaled-down technology will be designed to be incorporated into moored offshore vessels.

In a statement released this week, Carnegie said the launch of the new product was consistent with the company’s recent shift in focus towards the development and commercialization of proprietary technologies to efficiently and cost-effectively convert wave energy into electric energy.

The company, which started life as Carnegie Wave Power, went into voluntary administration in early 2019 after a series of blowouts and losses in the former microgrid subsidiary Energy Made Clean and the termination of last minute of a $ 16 million project contract.

Just before being reinstated at ASX in October of that year, Carnegie chairman Terry Stinson said the company had experienced “a very significant cultural reset” during its decline in administration.

“Reflecting on the past two years and the process of coming back to the brink has served to teach us painful but important lessons that are not soon forgotten,” Stinson said.

“Board members and key personnel have used this learning to bring the business back from administration because we believe in Carnegie and wave energy.

“We continue to believe that our CETO technology, as part of the emerging wave energy industry, can be a major contributor to reducing harmful emissions and contributing to a cleaner world for generations to come. “

To that end, Carnegie hopes MoorPower can be used to decarbonise the energy needs of offshore operations, particularly in aquaculture, whose operations such as supply barges move further offshore, removing their access to electricity. down.

For now, that means they rely on diesel generators, which lead to high costs and high carbon emissions, along with other environmental risks such as fuel spillage.

But MoorPower can be deployed for any type of moored vessel and is not limited to fish farming – and Carnegie’s vision for the technology is that it will be an integrated solution with other offshore renewable energy systems. , especially hydrogen and batteries.

“The elegance of the MoorPower aquaculture app for Carnegie is that these barges are already constantly moving with the waves and we have the electricity customer and an existing motor (the infrastructure being moved by the waves) in one package. pre-existing, ”said Carnegie’s CEO, Jonathan Fiévez.

“We essentially optimize our PTO and our CETO controller depending on the application and to offer a competitive offer.

“The technology also extends our reach in the market, while complementing the technical advancements made on our CETO technology.

“Wave energy has the advantages of consistency and predictability, and in some places the wave may be the only renewable energy that is practical,” Fiévez said.

Academic and industrial partners in the demonstration project include DNV GL Australia, Advanced Composite Structures Australia, University of Tasmania, Climate KIC / Australian Ocean Energy Group, AMC Search and University of Queensland.

In addition to funding from the Blue Economy CRC, the project will be funded by $ 265,000 from Carnegie and $ 1.8 million in in-kind support from all project partners.

“We look forward to the opportunities that MoorPower technology presents for the aquaculture industry and the expansion into high-energy offshore sites using clean and reliable energy solutions,” said Dr John Whittington, CEO of Blue Economy CRC.

“The project enables collaboration between experts in the field led by Carnegie Clean Energy and project partners across the country. “
