The First Tidal Generator in North America Is Now Online

Avery Thompson for Popular Mechanics:  The first tidal generator in North America has gone online this month in the Bay of Fundy, and is expected to generate enough electricity to power 500 homes.

While most hydro generators harness the energy of falling water, or the energy of the waves, tidal power uses the energy of the high and low tides. At the Bay of Fundy in Nova Scotia, which has the largest tides in the world, that energy is being harnessed to generate 2 megawatts of electrical power.

In the Bay of Fundy, the difference between high and low tide is about 56 feet. Approximately 115 billion tons of water flow in and out of the bay every tidal period. Two renewable energy developers, OpenHydro and Emera, decided to build turbines on the seafloor that could harness that power.  Cont'd...

Minesto's tidal energy technology awarded as most promising in the industry

On Tuesday evening, in a global competition of the most prominent players in the industry, leading tidal energy developer Minesto won the award for the Most Promising Turbine Concept at the International Tidal Energy Summit in London.

Tidal demonstrator to be built by HydroQuest and the CMN group

Implemented with support from the University of Caen Normandie, this project involves installing an ocean-based 1 MW hydrokinetic tidal turbine at the Paimpol-Brhat site, as part of an agreement with EDF, from the second half of 2017.

PTEC PARTNERS WITH WORLD-LEADING AND STATE-OF-THE-ART TIDAL TURBINE MANUFACTURERS

The 30MW project, to be created off the Isle of Wight, will allow long-term operation of SCHOTTEL HYDRO and TOCARDO turbine arrays, simultaneously optimising their performance and delivering reliable electricity to the grid. PTEC is also expected to create and safeguard hundreds of jobs and attract significant investment into the local economy, building on the success of the existing British marine and offshore wind sectors.

New milestone in Australian tidal energy

In an important step for this emerging form of renewable energy, a tidal energy turbine has been installed in the Tamar estuary in Launceston, Tasmania, as part of a project to investigate and optimise the device's performance.

Making waves: Shetland tidal power breakthrough is another world first for Scotland

Martin Hannan for The National:  HOUSEHOLDERS on the Shetland Isles were not aware of it, but when they plugged in their kettles recently, they were sharing in a bit of history.

For the Shetland Tidal Array at Bluemull Sound, installed by Nova Innovation of Edinburgh, has become the world’s first tidal power array to be connected to a grid and deliver power on a commercial basis – to dozens of homes on the islands.

The achievement has been hailed by environmentalists and the renewable industry as a turning point in the development of marine power.

Nova had shown its technology could work with a single turbine which generated electricity in March. But the installation of second turbine that is also working to the grid proves that large tidal power arrays can and do work. Commercially viable tidal power is seen as something of a Holy Grail by the industry, since it is one of the few renewable energy sources that is entirely predictable – as one industry source once put it: “there will be tidal power available as long as the moon is in the sky”.  Cont'd...

NOVA INNOVATION DEPLOYS WORLD'S FIRST FULLY OPERATIONAL OFFSHORE TIDAL ARRAY IN SCOTLAND

The second in a series of three 100 kW turbines was deployed alongside the first turbine in August 2016, making this the first offshore tidal array in the world to deliver electricity to the grid. Nova's success heralds a new era for tidal energy as a long-term source of predictable renewable power (unlike other forms of renewable energy).

PTEC, A WORLD LEADING TIDAL POWER PROJECT, RECEIVES APPROVAL

The Marine Management Organisation (MMO) has today granted its approval of the offshore elements of PTEC, a transformational 30MW tidal power project. The onshore part of the project was approved by the local planning authority last year. PTEC is now the largest consented tidal stream energy project in England and Wales.

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:

Minesto orders turbine prototype from SCHOTTEL HYDRO

The Swedish marine energy company has now placed an order for a prototype of the turbine, with delivery in early 2017.

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.
