Several groups working on wave energy on the British Columbia coast gathered in Ucluelet this week to discuss developments in the industry and update local projects.

Representatives from the non-profit Ocean Renewable Energy Group (OREG) chaired the community open house, held June 1 at the Ucluelet Community Centre.

Also in attendance were academics, developers, and representatives from all levels of government, including the Yuu-cluth-aht First Nation and the District of Ucluelet.

OREG executive director Chris Campbell said developing the technology to harness energy from the ocean is a “long, slow process,” but Canadian companies are active internationally, “so it’s gradually becoming more and more real.”

The Ucluelet/Tofino area has long been considered an ideal site for an ocean renewable energy project given its coastal location and proximity to the BC Hydro grid.

“Ocean renewable energy is something that’s been making rattling noises for quite a few years in our area,” said Ucluelet mayor Eric Russcher. “It would be a new and different world we live in but an exciting prospect for us all.”

According to information from OREG, preliminary studies indicate the wave energy potential off Canada’s Pacific Coast is equal to approximately half of Canada’s electricity consumption.

There seems to be a new energy behind wave power in recent months, given in part to new advances in technology, and also specifically in B.C. because of the Liberal government’s Clean Energy Act, which has been tabled in the legislature but has yet to be passed.

Jeff Turner from the Ministry of Energy, Mines and Petroleum Resources said the Act is meant to achieve energy efficiency while maintaining low rates, generate employment in the clean energy sector, and reduce greenhouse gas emissions.

While critics of the Act say it gives the province oversight on major projects like the Site C dam on the Peace River and could be mean higher hydro rates, the announcement has helped kick start development in areas like wave energy, where researchers are currently focused on pinpointing potential outputs.

Two wave energy projects are in development on the West Coast; one for the waters off Ucluelet and one in close proximity to the Hesquiaht communities at Hesquiaht Harbour and Hot Springs Cove.

John Gunton of SyncWave Systems Inc. presented his company’s plan for the SyncWave Power Resonator, a buoy class device that would be slack moored in depths of up to 200 metres. Simply put, this device captures energy from the upward and downward motion of the wave. Gunton said the company has provincial and federal funding, but is looking for a $3 million investment to complete its first two phases of development for placement near Hesquiaht Point.

A test resonator placed eight kilometres off Ucluelet in 40 metres of waters in December was collecting data for a period of about one month until a mast on it was destroyed. It was repaired, upgraded and redeployed in late April and a website will be set up by a group called the West Coast Wave Collaboration that is comprised of academics and industry representatives to transmit power data. Local partners in this project include the Ucluth Development Corporation, the District of Ucluelet and Black Rock Resort.

The other technology is a near shore device, placed in depths of 35 to 50 metres. The CETO device is owned by Carnegie Wave Energy of Australia, and was presented by David King at the open house. Seven metre cylinders capture wave energy and pump it to an onshore turbine. A government grant will also assist in the development of this technology.

But Jessica McIvoy of OREG said there are many questions left to be answered including what are the impacts on the ocean environment and sea life of such devices, and in turn how will the devices last in the ocean?

Campbell said an adaptive management approach to the technology seems like the best option to proceed with preliminary work, taking into account “critical indicators” in the natural environment.

Yuu-cluth-aht chief councillor Vi Mundy said she’s interested in these indicators after hearing concerns from her community, from fishers for example: “I’m hearing questions like what kind of impact will there be and what kind of standards have been developed so far [in the wave energy industry].”

But she also noted young people in her community are asking for green development that will provide year round employment.

“It’s really good to see that in young people,” Mundy said.

Anyone with questions about wave technology on the coast is invited to contact OREG at questions@oreg.ca.

ceto-overview1For millennia, Australia’s rugged southern coast has been carved by the relentless action of waves crashing ashore.

The same wave energy could soon be harnessed to power towns and cities and trim Australia’s carbon emissions.

“Waves are already concentrated solar energy,” says Michael Ottaviano, who leads a Western Australian firm developing a method to turn wave power into electricity.

“The earth has been heated by the Sun, creating wind, which created the swells,” he told Reuters from Perth, saying wave power had the potential to supply all of Australia’s needs many times over.

Ottaviano heads Carnegie Corp, which has developed a method of using energy captured from passing waves to generate high-pressure sea water. This is piped onshore to drive a turbine and to create desalinated water.

A series of large buoys are tethered to piston pumps anchored in waters 15 to 50 metres deep (49 to 131 feet). The rise and fall of passing waves drives the pumps, generating water pressures of up to 1,000 pounds per square inch (psi).

This drives the turbine onshore and forces the water through a membrane that strips out the salt, creating fresh water in a process that normally requires a lot of electricity.

The CETO (named after a mythical Greek sea creature) pumps and buoys are located under water, differing from some other wave power methods, for example, those that sit on the surface.

The CETO concept was invented in the 1970s by a Western Australian businessman Alan Burns and initial development began in 1999, followed by completion of a working prototype by 2005.

Ottaviano says the company, which works in partnership with British-based wind farm developer Renewable Energy Holdings and French utility EDF, is in the process of selecting a site for its first commercial demonstration plant in Australia.

The 50 megawatt plant, enough to power a large town, would cost between A$300 million to A$400 million ($193 million to $257 million) and cover about 5 hectares (12.5 acres) of seabed.

Funding could be raised from existing or new shareholders, he believes.

Several sites in Western Australia, including Albany in the south and Garden Island off Perth, looked promising.

“There’s significant interest in these sorts of projects, even in the current financial environment,” he added.

And a 50 MW plant was just a drop in the ocean.

He pointed to a study commissioned by the company that said wave power had the potential to generate up to 500,000 MW of electricity along the southern half of Australia’s coast at depths greater than 50 metres (165 feet).

At shallower depths, the potential was 170,000 MW, or about four times Australia’s installed power generation capacity.

Interest in renewable energy in Australia and elsewhere is being driven by government policies that enshrine clean energy production targets as well as state-backed funding programmes for emerging clean-tech companies.

“Australia is going to be one of those markets because of what the government is doing to drive investment in this sector. For starters, there’s quite a bit of direct government funding for projects like this,” he said.

The federal government has also set a renewable energy target of 20% by 2020, which is expected to drive billions of dollars worth of investment in Australia over the next decade, with much of it going into wind farms.

A second company, BioPower Systems, is developing underwater wave and tidal power systems and expects to complete pilot projects off northern Tasmania this year.

The company’s bioWAVE system is anchored to the sea bed and generates electricity through the movement of buoyant blades as waves pass, in a swaying motion similar to the way sea plants, such as kelp, move.

Tidal power, in which electricity is generated by turbines spinning to the ebb and flow of tides, has not taken off in Australia, partly because of cost, but is expected to be a big provider of green power in Britain in coming years.

Last week, Britain announced five possible projects to generate power from a large tidal area in south-west England. The largest of the projects could generate 8,600 MW and cost 21 billion pounds ($29 billion).

Ottaviano believes wave power is one of the few green technologies that can provide steady, or baseload power.

Wind and solar photovoltaic panels can only operate at 25 to 30% efficiencies because neither the wind nor the sun are permanently available.

Government policies should promote the development of technologies that delivered large-scale, high-availability clean power competitively, he said.

“If you look from an outcome point of view and leave it up to the market to work out how that is going to be achieved, it comes down to geothermal certainly being one of the potential technologies because (of) its high availability and also potentially cost-competitive and harnessable at large scale,” Ottaviano said.

Australia has large geothermal potential in remote central and northern areas.

“Wave is another logical one because it is high availability. It is 90 to 100% available in most sites around southern Australia.”

“You could power the country 10 times over.”

Warrnambool — Rising seas and bigger waves caused by climate change could have a positive spin-off for the south-west – wave power.

A report published by the Commonwealth Scientific and Industrial Research (CSIRO of Australia) researchers has found an increase in the frequency of storms generating larger waves off Australia’s southern coast over the past 45 years.

One of the report’s authors, Dr Mark Hemer of CSIRO Marine and Atmospheric research, said harnessing wave power to generate electricity was one of the potentially positive effects of climate change.

“Areas like Warrnambool that are known for producing large, consistent waves might be a good spot for renewable energy projects,” he said. At least three renewable energy companies in Australia had prototype systems to turn wave energy into electricity which could be operating commercially by 2010, Dr Hemer said.

New South Wales company Oceanlinx is in the process of securing permits to launch a project in Portland to harvest wave energy. Portland is also among a number of sites being considered by Western Australian wave energy firm Carnegie Corporation.

The CSIRO research also identified areas of coast which might be vulnerable to potential problems caused by powerful waves such as coastal flooding, inundation, increased storm activity and underwater habitat disruption.
