Pelamis Offshore Wave Energy in Portugal

Wave EnergyA Portuguese energy company called Enersis is funding a commercial wave energy project in Northern Portugal. Construction will begin at the end of October 2006. The project will use Pelamis wave generator technology (manufactured by Ocean Power Delivery) to harness energy from the ocean. After two decades of research and testing at the Lisbon Technical Institute, the first stage of this ocean energy project is intended to produce 2.25 megawatts and power homes through the nation’s state-run electrical grid system. Ocean Power Delivery is considered to be the world’s leading ocean energy company.

“This project, begun in 2003, is now in the world vanguard,” said Rui Barros, Enersis director of new projects. “Of all the varieties of renewable energy, perhaps harnessing the waves is the only one where Portugal might have a real future,” he said. With its geographical position and extensive coastline giving access to the larger and more powerful Atlantic waves, official estimates from Portugal’s State Secretariat for Industry and Innovation have predicted wave power could account for up to 30 percent of the country’s gross domestic product by 2050. Renewable energy experts have determined wave farms in Portugal could yield as much as three times as much energy as that produced by a wind turbine park for the same investment cost.

A report published by the Portuguese Wave Energy Center has confirmed the long-term economic benefits of wave energy for the country and calls on the government to put in place a strategy to attract foreign investment into Portuguese wave power ventures. “The utilization of wave energy may have a significant socio-economic impact on Portugal, namely regarding renewables, creation of job opportunities, opportunity of exportation of equipment and services, innovation and development of technology, as well as companies dedicated to the exploitation of other oceanic resources,” the report says.

Wave EnergyRelatively new in development, modern research into wave power had its beginnings in response to the 1973 oil crisis. Professor Stephen Salter of the University of Edinburgh pioneered research into wave energy with his prototype machine “Salter’s Duck.” Though the duck remains a laboratory prototype, the machine remains the standard for wave energy. The experimental device converted around 90 percent of the wave power by bobbing up and down on the surface of the water – like a duck. Despite its early promise though, setbacks and a general lack of government support saw the project shelved.

However, with the Portuguese system set to be the world’s first commercial wave energy venture, the exploitation of wave power has found itself back on the renewable energy agenda.

Following the Enersis announcement, other countries naturally suited to the development of wave power have expressed their interest in introducing the technology. Following his recent visit to Aguadoura, Scottish Executive Enterprise Minister Nicol Stephen announced that a portion of the 8 million pounds already set aside for renewable marine energy in Scotland would now be directed towards installing the Pelamis wave devices at the European Marine Energy Center in Orkney.

“I am committed to supporting Scotland’s huge wave and tidal energy resource. Scotland has a real opportunity to be a world leader in this field,” said the minister shortly after his visit to view the wave energy project in northern Portugal. “The opportunity now exists to create a multi-million pound industry based in Scotland, employing thousands of highly skilled people,” he said.

However, environmental group Friends of the Earth, while supporting the minister’s announcement, sounded a warning that any delays in introducing the wave power technology could lead to an exodus of Scottish expertise.

“Wave and tidal power could supply a fifth of U.K. energy needs and Scotland is ideally placed to generate significant amounts of this pollution-free energy,” said Friends of the Earth chief executive Duncan McLaren. “However, there is a danger that unless we see full-scale devices in our waters soon that the world-leading expertise Scotland has built up will rapidly depart these shores,” he said.

As part of the government supported alternative energy plan, another 28 wave power devices will be installed in Portugal within a year, reaching a target of 22.5 megawatts of electricity produced using wave energy. The project is supported by state run power company Energias de Portugal.

    It seems their wave farm in Portugal was a failure:

    The machines are tied up at a dock! Even though their web site says that the project is operating – come on guys be truthful!

    Sorry to hear that. With any new technology, we expect there to be some break-in time. Leaks in the buoyancy tanks doesn’t seem like such a big deal, but the loss of funding is what killed this project. Sounds like an opportunity for someone else to buy those things cheap and see what can be done. Unfortunately, everyone hit the same cash crunch together.
