Wave Glider ocean robots to track sharks in northern California

If you’ve ever sat in a beach-side coffee house wondered if there was a white shark in the vicinity, then wonder no more because now there’s an app for that. A team of Stanford University researchers lead by Prof. Barbara Block is deploying a fleet of static buoys and Wave Glider robots to turn the waters off the coast of San Francisco into a huge Wi-Fi network to track tagged fish and animals. This will allow scientists to better understand sea life movements, but the project also includes offering a free app to the public that will allow them to track northern California white sharks on their tablets and smartphones.Read More

Lockheed Martin and OPT team up on Australian 19 MW wave energy project

Lockheed Martin has teamed up with Ocean Power Technologies (OPT) to develop one of the world’s largest wave energy generation projects. The 19-megawatt project to be located off the southern coast of Australia in Portland, Victoria, will be built around OPT’s PowerBuoy technology that has previously been trialed by the U.S. Navy off the coast of New Jersey for powering remote sea-based radar and communications systems.Read More

Eco Wave Power developing two new wave-power devices

Israel's Eco Wave Power is just entering the second phase of proving its new wave energy harvest and conversion system that's claimed to produce cheaper energy than existing coal-fired power plants. Energy is captured by the influence of rising and falling waves on two proprietary float designs called the Wave Clapper and Power Wing, which are installed on existing, stable structures. The floats are said to be capable of gathering energy from both high and low waves, which is fed through undersea cabling to a land-based power plant for conversion to usable electricity.Read More

New wave of ocean energy to be trialed off the coast of Australia

Anyone who has ever been scuba diving in a bull kelp forest will tell you - the stuff does not stand still. The marine aquatic plant consists of a long skinny-but-tough stem (or stipe) that is anchored to the sea floor and topped with a hollow float, from which a number of "leaves" (or blades) extend to the surface. The result is a seaweed that extends vertically up through the water column, continuously swaying back and forth with the surging waves. The researchers at Australia's BioPower Systems evidently looked at that kelp, and thought, "what if we could use that swaying action to generate power?" The result was their envisioned bioWAVE system, which could soon become a reality, thanks to a just-announced AUD$5 million (US$5.1 million) grant from the Victorian Minister for Energy and Resources.Read More

Autonomous wave energy PowerBuoy device commences sea trial

Maritime surveillance and monitoring systems that require remote power at sea often rely on diesel generators that need frequent maintenance and fuel replenishment. Now New Jersey-based wave energy company Ocean Power Technologies (OPT) has commenced sea trials of an autonomous wave energy device that provides clean energy for sea-based radar and communications systems in remote ocean locations and in all wave conditions.

Ship-based system designed to harness energy from waves

Why don’t we have stationary commercial fishing platforms that are anchored offshore, where they sweep the waters with their nets, sending the captured fish back to shore through a pipeline? Well, because it’s simpler and more efficient to send fishing boats out to catch the fish and bring them in. Thinking along those same lines, the Fraunhofer Center for Manufacturing Innovation has proposed a ship-mounted renewable energy-harvesting system, that would be powered by the ocean’s waves.Read More

Move over Nessie - new wave power system sighted at Loch Ness

Solar power might be stealing the limelight when it comes to the subject of renewable energy, but ocean waves are also seen as a great, largely untapped source of clean power. The latest news surrounding attempts to mine this potentially limitless energy source comes from Scottish marine energy technology developer, AWS Ocean Energy, which has started testing its new wave energy device in Loch Ness in the Scottish Highlands.

Oyster - the world's largest working hydro-electric wave energy device

Rounding off a big week in renewable energy is news that the world’s largest working hydro-electric wave energy device has been officially launched in Scotland. Known as Oyster, the device, stationed at the European Marine Energy Center (EMEC) Billia Croo site near Stromness, was installed this year and is, at present, the world’s only hydro-electric wave energy device which is producing power.

Oyster ocean power system to provide 1 GW by 2020

A new milestone for marine energy was achieved recently when UK based Wave and Tidal Technologies company Aquamarine Power Ltd signed a 1,000 MW (1 GW) Development Agreement with the renewable energy development division of Scottish and Southern Energy, Airtricity. Aquamarimes's Wave Power device, called Oyster, is a near shore hydroelectric wave power system. Still at the full scale prototype stage, the Oyster is based around a large movable buoyant barrier structure that is mounted on the seabed in depths of 10 – 12 m (33 – 40 ft) and pivots like a gate.Read More
