Landmark Gibraltar station is just the start for Eco Wave Power

Last month, Gizmag was on the ground in Gibraltar as Eco Wave Power (EWP) inaugurated the first ever grid-connected wave power station in Europe. It was a big moment for the company, but only hinted at its plans for the future, with much larger efforts on the horizon. With the Gibraltar station off to a good start, Gizmag sat down with EWP's co-founders Inna Braverman and David Leb to discuss the present and future of the company.Read More


Gibraltar to suck up 15 percent of its power from waves

While world leaders meet in Paris to discuss reducing carbon emissions believed to contribute to climate change, the government of Gibraltar is putting its own renewable energy plan into action. The iconic British territory has inked a deal with Eco Wave Power to install a 5-megawatt wave energy power station to harvest electricity from the rising and falling waters of the Mediterranean.

Azura wave energy system deployed in Hawaii

Although wave energy-harvesting systems are often just presented as concepts that may someday see actual use, one was recently deployed in Hawaii to provide power to the municipal grid. Built by Northwest Energy Innovations, the Azura device will remain in operation for a 12-month assessment period, with an eye toward eventual commercialization.Read More

CorPower system gives wave power the gears

Harnessing wave power can be a tricky business. It's one thing to build a device that simply moves up and down with the waves, but another to build one that's efficient enough to be cost-effective. Swedish company CorPower Ocean claims to have done just that, however. Its wave energy converter buoys reportedly generate five times more energy per ton of device, at a third the cost of other wave power systems. Read More


Old trawler now harvests wave power instead of fish

An old fishing trawler has been given new life in Norway, where it's now anchored offshore in the Stadthavet area and serving as a wave power plant. It's part of a project which ultimately calls for larger, purpose-built vessels to convert wave motion into electricity. Read More


The Odyssée desalinator: Using the power of the ocean to cleanse its own salty waters

Watching on as the waves crashed against the cliffs of South Corsica, France, mechanical engineer Dragan Tutić knew some were already drawing on power from the ocean to generate electricity. But a possible use for all that motion in the ocean that had been largely unexplored, as far as he knew, was turning its salty seawater into the fresh, drinkable variety on the spot. In the following two and a half years, Tutić and his team designed and tested a prototype for a wave-powered desalinator, and now hold hopes of deploying the system in regions where water scarcity threatens the survival of coastal communities.

WaveNET – the floating, flexible wave energy generator

Scotland's Albatern is putting a new, modular spin on renewable energy generation. WaveNET is a scalable array of floating "Squid" generator units that harvest wave energy as their buoyant arms rise and fall with the motion of the waves. Each Squid can link up to as many as three others, effectively creating a large, floating grid that's flexible in every direction. The bigger this grid gets, the more efficient it becomes at harvesting energy, and the more different wave movements it can extract energy from. Albatern's 10-year target is to have 1.25 kilometer-long floating energy farms pumping out as much as 100 megawatts by 2024.Read More


Seafloor carpet mimics muddy seabed to harness wave power

Many organizations around the world are looking at ways to harness the power of waves as a renewable energy source, but none are covering quite the same ground as a team of engineers from the University of California (UC), Berkeley. The seafloor carpet, a system inspired by the wave absorbing abilities of a muddy seabed, has taken exploring the potential of wave power to some intriguing new depths.Read More
