Carnegie joins forces with Enel to develop CETO wave energy technology

Perth-based alternative energy developer Carnegie Clean Energy (ASX: CCE) has entered into a A$1.6 million collaboration agreement with global renewables player Enel Green Power (EGP) to further its CETO wave energy technology.

Under the terms of the agreement, Carnegie and EGP will work together to research, develop and deploy current and future CETO technologies, including the Albany Wave Energy Project south of Perth, as well as opportunities for CETO in Australia and overseas.

EGP will also join the technical advisory committee of Carnegie and the Wave Energy Research Centre run by the University of Western Australia with support from the WA state government.

EGP has a global presence in the renewables energy sector with interests in Europe, the Americas, Asia, Africa and Oceania.

The company manages around 42,000 megawatts of renewable energy plants across wind, solar, geothermal and hydropower, and is involved in the integration of innovative technologies into renewable power plants.

Albany wave project

The Albany Wave Energy Project – which has received funding support of $15.75m from WA’s Department of Primary Industries and Regional Development and $11.7m from the Australian Renewable Energy Agency – involves the design, manufacture and installation of a CETO 6 unit in Carnegie’s existing licence area offshore from Albany.

The unit will be operated for a period of 12 months during which time Carnegie will run tests to optimise system performance, validate computational modelling results, refine installation and removal methods, and validate the system’s reliability.

If the project is deemed successful, Carnegie plans to develop a 20MW wave farm and potentially a 100MW expansion.

Carnegie managing director Dr Michael Ottaviano said Albany is ideally suited as a wave energy test site.

“Albany has one the most consistent wave energy resources in the world, experiencing a greater than 1m swell, 100% of the time,” he said.

“The integration of this 24/7 wave resource with the region’s infrastructure, including an existing wind farm, has the potential to provide a more stable, consistent and reliable renewable energy to [WA’s] electricity grid.”

CETO technology

Carnegie’s CETO technology harnesses the renewable energy present in ocean waves and converts it into zero-emission electricity and zero-emission desalinated water.

Unlike other wave energy devices, CETO operates underwater where it is protected from large storms and invisible from the shoreline.

The fully submerged buoys drive pumps and generators which are contained offshore, within the buoy itself, and deliver power back to shore via subsea cables to power desalination plants as well as for export into the grid.

The CETO 6 wave energy unit builds on intellectual property first lodged by Carnegie in 2013 and incorporates onboard power generation and power take-off modules to boost power production and unit efficiency.

The unit will have a nameplate capacity of 1.5MW and multiple moorings to deliver more than twice the energy production of the previous single-moored CETO 6 design.

Carnegie said it will aim to be competitive with other mainstream renewable technologies once CETO is being manufactured in high volumes and built at a large project scale.

Wave energy

Wave energy remains one of the largest, untapped renewable resources globally.

The World Energy Council (2016) forecasts an installed capacity of ocean energy of up to 62,000MW by 2040.

Meanwhile, Ocean Energy Europe forecasts show the global market for ocean energy could reach 337GW of installed capacity by 2050 incorporating wave, tidal, and ocean thermal conversion.

Of this, around 188GW is expected to be wave energy.

Emergence of MPower

Carnegie has reached an agreement with Tag Pacific (ASX: TAG) whereby Tag would acquire 100% of Carnegie’s subsidiary Energy Made Clean.

The new group, to be known as MPower, will capitalise on the emerging off-grid and fringe-of-grid solar, battery storage and microgrid market and will specialise in the engineering, procurement, construction (EPC) and build, own, operate (BOO) space.
