Robotics principles help wave energy converters better absorb power of ocean waves

Phys.org: "We are working to create methodologies and technologies that private companies can harness to create wave energy devices that will enable them to sell power to the U.S. grid at a competitive price,"

B.C. wave energy holds huge renewable potential say experts

Wanyee Li for Ottawa Metro: A group of scientists say now is the time to invest in wave energy because B.C. has the potential to become a destination for wave-technology companies around the world.

Wello's Penguin WEC generates electricity at EMEC grid-connected wave test site

From Power-Technology: High-technology company Wello's Penguin wave energy converter (WEC) has successfully generated power into the national grid off the west coast of Orkney in Scotland, UK.

Edinburgh technology duo secure £2.5 million to turn wave power into electricty

It's a problem that has long thwarted wave energy pioneers - how to transform the slow back and forth motion of waves into a reliable and cost-effective stream of electricity.

Catch wave power in floating nets

Zhong Lin Wang for Nature:  Nature provides three sources of energy for free: sunlight, air and gravity. Solar and wind power are increasingly exploited, gravity less so. Hydraulic power plants harvest energy from flowing rivers. Tidal energy can be gathered along some inlets and coasts. But few places are suitable for dams or barrages, which can also damage the environment. By contrast, oceans cover about 70% of Earth’s surface. Wave energy is plentiful day and night, whatever the weather. Capturing it requires little land and raises few safety or security concerns. Yet hardly any of this ‘blue energy’ is being generated. Today’s wave farms produce no more than 1–10 megawatts at any one time, enough to power a town. No commercial wave farms currently exist.   Full article:

Australia's Carnegie Wave Energy Project Sets World Record

Joshua S Hill for CleanTechnica:  Australia’s Carnegie Wave Energy Project has set a new world record after completing 14,000 cumulative operating hours, the highest ever recorded. The news was announced by the Australian Renewable Energy Agency (ARENA) this week, which provided $13.1 million in funding. The $40 million project uses CETO wave energy technology, and was the world’s first array of wave power generators to be connected to an electricity grid. For the past 12 months, the CETO 5 project has used an array of three offshore wave power generators to provide electricity and potable desalinated water to Australia’s largest naval base, HMAS Stirling, on Garden Island in Western Australia. “ARENA is proud to help local companies, like [Carnegie Wave Energy Limited], develop new renewable energy solutions that have the potential to change the way the world generates electricity,” said ARENA CEO Ivor Frischknecht. “We do this by providing Australian innovators with the support they need during the critical RD&D period, when patient funding is essential.”   Cont'd...

MacGregor winch expertise employed in innovative wave energy capture

The system is called NEMOS and it is ideally suited to work in combination with offshore wind farms, where it can share electrical infrastructure, which lowers the levelised cost of energy (LCOE), and smooth fluctuations in power-generation, therefore supporting greater commercial viability of renewable energy capture.

This Device Could Provide a Third of America's Power

Sam Grobart for Bloomberg:  There are 332,519,000 cubic miles of water on the planet. That's 352,670,000,000,000,000,000 gallons just sloshing around out there.  Anyone who's ridden or been tossed by a wave has a sense of the kinetic energy contained in our perpetually moving oceans. If we could harness it, it could provide a clean, renewable source of energy. But efforts to turn our oceans into power generators—often in the form of "aqua-mills," windmill technology adapted to water—have foundered on the complexity of their many moving parts in the corrosive and remote environs of the sea.  A new approach, developed by a company called Oscilla Power, applies all that kinetic energy to a solid piece of metal instead of using it to turn the blades of an impeller. That creates an alternating magnetic polarity in the metal that can be converted into electrical current.  Oscilla's technology, which is nearly solid-state, may prove far more durable than any other ocean-power project, increasing the chance to draw power from our oceans cleanly, meaningfully, and endlessly.   View video here:

EFFECTS OF MARINE ENERGY ON THE ENVIRONMENT

Although marine power's damage to the environment is significantly less than its energy counterparts, the possible affects to existing ecosystems must be considered.
