Pelamis Wave Power Building Wave Energy Project in Portugal
Scotland's Pelamis Wave Power has started operating what Portuguese officials say is the world’s first commercial wave-power project, located five kilometers (three miles) off Portugal's northern coast. The €9 million Aguçadoura project could be expanded from 2 MW to 21 MW if initially successful. - Read More

Australia can clean up on wave power: Carnegie
Clean power developer Carnegie Corporation says more than a third of Australia’s base-load power needs could be economically generated by wave technology, according to a report commissioned by the company. The report, compiled by RPS MetOcean, says that Australia has a potential near-shore wave energy resource of about 171,000 megawatts (MW) – four times the country’s total installed power generation capacity, Carnegie said. - Read More

Osmotic power generation - a new energy resource?
Osmosis – the way water automatically flows from a weak solution into a stronger one – is a fundamental to biological life. Now the process could also generate our electricity. Various researchers have tested the idea of using a semi-permeable membrane to separate freshwater and seawater, and using the pressure generated as water flows from one to the other to drive a turbine. The pressure that builds up can be as much as 25 atmospheres. - Read More
Pelamis Wave Energy Converter, Scotland
A pilot project: Pelamis Wave Energy Converter, based on the Orkney Islands north of Scotland. Pelamis resembles a huge snake made up of four 40-meter tubes, linked end to end, riding on the sea surface. Waves make the segments flex against each other, driving hydraulic rams that, in turn, drive electric generators. By next year, said the operator, Pelamis Wave Power Ltd. (www.pelamiswave.com), it hopes to supply the power that 10 percent of Orkney’s 20,000 inhabitants need. - Read More
