The European Commission has cleared French state support for an
experimental tidal power plant off the northwestern coast of the
country, saying the aid given was in line with European rules.
France will support the construction of four turbines, which
will each produce 1.4 megawatts of electricity, through a direct
grant and repayable advances, the Commission said, without
stating the amount of money pledged.
The NEPTHYD (Normandie Energie PiloTe HYDrolien) pilot farm will
be located at Raz Blanchard, west of the Cotentin peninsular. A
subsidiary of Engie will build and operate the plant for 20
years.
The Commission said the project supported market entry of a
novel renewable energy technology, including turbines with
several innovative features, with aid limited to the cost of
producing electricity from the plant.

Taking just six months from the drawing board to realisation,
the BlueTEC Texel tidal energy platform was installed in the
summer of 2015 and is operating off the island of Texel in the
Netherlands. The prototype is producing electricity from the
tides into the local grid.
BlueTEC Modular was designed by Damen to be transported and
installed all over in the world to provide clean energy in
remote areas and small islands, replacing diesel generators. ;D

Just before the end of 2015, the platform was fitted with a more
powerful Tocardo T2 turbine and, in early 2016, the platform was
commissioned with a larger T2 tidal turbine. Currently the
platform generates clean electricity from the tides in the
Wadden Sea of The Netherlands.

Will This Tidal Project Spark a [i]Global Energy Revolution?
HTML http://www.pic4ever.com/images/128fs318181.gif[/i][/center]
By Richard Sadler
Ambitious plans have been drawn up for a network of "tidal
lagoons" around the UK coast that could provide up to a quarter
of the country's electricity—and there is potential to roll out
the technology in many parts of the world.
Tidal lagoons work by using a wall to capture a body of water in
the sea or a tidal estuary pushed in on the rising tide. The
water drives turbines as the tide comes in and then, as the tide
falls, the turbines are reversed and the energy from the falling
tide is harnessed again.
As Geoffrey Chaucer, one of the earliest English poets put it:
"Time and tide wait for no man." Unlike with wind and solar, the
amount of energy being produced from tides is predictable months
in advance and is now being recognized as a major renewable
resource.
More Tidal Lagoons
Planning approval has already been given for a £1.3 billion
pathfinder project at Swansea Bay, South Wales, described by
developers as "a scalable blueprint for a new, global,
low-carbon power industry." Another nine lagoons are planned
around tidal hotspots in the Severn Estuary and North-West
England/North Wales. These would have the potential to generate
25,000MW of electricity—enough to provide 12 percent of the UK's
electricity needs.
The company behind the proposals, Tidal Lagoon Power, already
has teams working in Northern France and India and is studying
opportunities in Mexico and Canada's Atlantic coast. Further
tidal lagoon markets may exist in South America, China,
South-East Asia and Oceania.
Tidal power is recognized by the EU's Joint Research Centre as a
key contributor to the continent's future energy mix. Its main
attraction is that, unlike other renewable energy sources, it
does not require the wind to blow or the sun to shine.
An oceanographer at Southampton University, Dr. Simon Boxall,
said the technology has improved to the point where tidal energy
was a "no-brainer," with the latest bi-directional turbines
capable of generating power on both incoming and outgoing tides.
He said that with sufficient investment it could provide up to a
quarter of UK electricity needs within 20 years.
"We can always rely on tides—they come in and they go out and
they will continue doing so for thousands of years. Parts of the
UK have tidal ranges in excess of 15 meters, so that's a heck of
a drop of water and that's happening twice a day—or four times a
day when you count the water coming in and going out," said Dr.
Boxall.
"The other great advantage is that the tides aren't the same in
different locations, so if you've got a network of tidal power
stations you are always generating electricity: 24 hours a day,
seven days a week," added Dr. Boxall.
In December a former UK energy minister, Charles Hendry,
published an independent review, concluding: "Power from tidal
lagoons could make a strong contribution to UK energy security,
as an indigenous and completely predictable form of supply."
He said the UK was well-placed to take a global lead and with
economies of scale and mass manufacture of turbines, turbine
housing and other components costs could be substantially
reduced.
Cheap Electricity
To be viable the new industry would require subsidies, with a
guaranteed premium price for electricity generated. However,
Hendry calculated that in the long term tidal lagoons will work
out cheaper than wind and "significantly less expensive" than
nuclear. And they could go on generating for 140 years—providing
clean, subsidy-free energy long after other energy plants have
been decommissioned.
The technology is not without its drawbacks. Artificial lagoons
can cause increased silting-up of shipping lanes. Tidal
estuaries are also important for wading birds, marine mammals
and migratory fish and conservation groups have warned that the
ecological impacts of tidal lagoons are not well understood and
that any roll-out of lagoons in the UK should be conditional on
the Swansea project being tried and tested. Backers of the
technology say management practices can be adapted to address
such concerns—and they point out that lagoons can provide
environmental benefits, acting as artificial reefs for marine
wildlife.

The UK government is expected to announce a final decision on
the Swansea Bay project within the next few months.

[center]Weaning off oil, Scottish islands eye renewable future

[center]A "Welcome to Lerwick" sign in the Shetlands, which is
using its strong winds and stormy seas to turn the islands into
a[i] European renewable energy giant [/i][/center]
Strong winds and stormy seas have helped turn the Shetland
Islands in the North Atlantic into a European renewable energy
giant, producing more power than it knows what to do with.
The tidal power underwater turbines that were completed last
month are only the latest green energy project for an
archipelago that has been reliant for decades on the North Sea
offshore industry.
Even homeowners are getting in on the act with small wind
turbines in their gardens and solar panels on their
roofs—somewhat optimistically in an area where winter daylight
lasts just six hours.
"We're not 100 percent self sufficient but we're quite a long
way towards it," Jim Dickson, 69, told AFP at his home in the
windswept village of Brae, referring to electricity generation
for his own house.
Dickson, who lives near the Sullom Voe oil terminal, can power
the building and an electric powered Nissan Leaf car from a
turbine in his garden with enough left over to feed into the
island's grid when conditions are favourable.
"What I make from the government for producing per kilowatt hour
more than pays for what I buy from the grid, so effectively
there is no power bill."
The former harbour master knows about the dangers of fossil
fuels.
He was winched aboard the out of control oil tanker MV Braer in
1993 during the worst cyclone on record in the North Atlantic,
in an ill-fated attempt to prevent it running aground.
His efforts to attach a tow rope failed and the ship crashed
into the rocks at Quendale Bay, spilling 84,700 tonnes of crude
oil into the sea.
The nation was aghast at images of Shetland's famous seabirds
drowning in black ooze.

Harnessing the sea
The oil industry in Shetland began in the 1970s with the
development of the North Sea fields. :P
The Brent field east of the archipelago became an emblem of the
industry, with "Brent Crude" becoming a benchmark for oil
trading around the world.
Oil giant Shell has announced plans to decommission the field
but new discoveries west of Shetland could give a boost to the
industry.
French energy firm Total has invested £3.5 billion (4.1 billion
euros, $4.4 billion) in a new gas plant near Sullom Voe that
opened last year to extract gas from its fields west of
Shetland, Laggan and Tormore.
HTML http://www.createaforum.com/gallery/renewablerevolution/3-200714183337.bmp
"Producing gas and oil from the west of Shetland basin is very,
very challenging," field operations manager Simon Hare told AFP
on a hill overlooking the plant, a sprawling development which
stands in sharp contrast to the rest of the islands' natural
beauty.

The gas plant is designed for a lifetime of 30 years.
But environmentalists are pinning their hopes on another energy
asset under the waters around Shetland.
"In tidal, we're very fortunate in Scotland," said Patrick
Ross-Smith, Shetland development officer at Nova Innovation,
which has installed three 100 Kilowatt turbines in the Bluemull
Sound.
Scotland has 24 percent of Europe's entire marine energy
potential because of its powerful tides.

"It's great to harness some of that in Shetland," he said.
The turbines' success has had the odd effect of creating too
much power.
"The Shetland grid is itself constrained now. It cannot take any
more renewables," he said.
Around 10 percent of the Shetland Islands' electricity is
generated from renewables and wind and tidal generators are only
licenced to produce up to that limit.

/>
HTML http://www.desismileys.com/smileys/desismileys_6656.gif
There is no connecting cable between Shetland and mainland
Britain and as the renewable energy cannot easily be stored to
ensure stable supply, the turbines have to be switched off from
time to time.
HTML http://www.createaforum.com/gallery/renewablerevolution/3-200714183312.bmp
The proposal for a connector line to link Shetland to the
mainland 200 miles (322 kilometres) away remains uncertain.
For Dickson, the more renewables the better.

"You will always need hydrocarbons to power your jumbo jet, for
example, but you shouldn't be making electricity with
hydrocarbons," he said.
"It's wrong, it's nonsense".

In March, the user selection board of the US$11.8 million
Funding Ocean Renewable Energy through Strategic European Action
(FORESEA) project awarded “Recommendations for Support” to 15
offshore renewable energy technologies. Scotrenewables, one of
the 15 recipients, received funding from FORESEA via EMEC to
test its SR2000.
In 2013, Switzerland-based engineering company, ABB, invested
$12 million in Scotrenewables after previously providing funding
for the SR2000. HydroWorld.com reported in December 2012 ABB
announced it invested $8.12 million in Scotrnewables, alongside
an additional $6.24 million from Fred Olsen and Total S.A.
[b]Andrew Scott, Scotrenewables chief executive officer,[/b]
said: “We are tremendously excited to have the SR2000
demonstrating the performance and cost advantages of our
floating tidal technology, in line with forecasts, whilst
delivering new benchmarks within the tidal sector. This
performance resets the bar for the costs of delivering tidal
power. Achieving this industry milestone is a goal the team at
Scotrenewables have worked tirelessly towards for a long time —
the credit lies with them for these fantastic achievements.”
Neil Kermode, EMEC managing director said, “Everybody at EMEC
offers their congratulations to Scotrenewables in reaching peak
power on the SR2000. This milestone is testament to years of
hard work and dedication shown by the Scotrenewables team. It
further demonstrates that through dogged, unrelenting innovation
tidal energy is getting ever closer to becoming part of our
carbon free energy mix.”
Scotrenewables said it is focused on building up generation on
the SR2000 during the immediate future and demonstrating its
power performance in parallel with the unit’s unique low
operational costs.

MeyGen Tidal Power Facility Exported 13.8 GWh Of ⚡
Electricity To The UK Grid In 2019[/center]
Tidal power doesn’t get a lot of love in the renewable energy
world these days but that doesn’t mean it couldn’t make a major
contribution to the world’s energy needs. The largest tidal
power installation in the world at the moment is the MeyGen
tidal stream project in the waters off the northern coast of
Scotland.
Last year, that facility exported 13.8 gigawatt-hours (GWh) of
electricity to the grid, enough to power 3,800 typical homes in
the UK. That’s about double the output of the MeyGen facility
the prior year, according to CNBC. Simec Atlantis Energy, which
owns and operates the MeyGen installation, says Phase 1A of the
project uses four 1.5 megawatt turbines. (Note: All photos

[center]

Simec Atlantis Energy has big plans for tidal power. Project
Stroma, formerly known as Phase 1B, will place 2 more turbines
on the ocean floor. Unlike Phase 1A, however, those turbines
will transmit electricity to the shore using a single undersea
cable. The company says that innovation will “significantly
reduce the costs associated with grid connection. The length of
power export cable as well as the amount of onshore conversion
equipment required for grid connection will be significantly
reduced, as will the amount of horizontal directional drilling
and the amount of vessel time required for cable installation.”

Tidal power so far is definitely in the experimental stage. It
needs to scale up quite a bit before it becomes attractive to
investors. Semec Atlantis Energy has all the permits in hand to
expand its tidal power operations. In Phase 1C, which is under
development, an additional 49 turbines with a total capacity of
73.5 MW are planned.
“The project will…..provide an investment opportunity for
commercial debt and equity providers to invest in tidal stream
projects,” the company says. “In addition, Phase 1C will create
an estimated 5,300 full time roles, repurposing jobs from the
oil and gas sector and placing Scotland at the forefront of an
estimated 25GW global export market for decades to come, as well
as significantly reducing LCOE.”

[center]Tidal Power Is Growing[/center]
Recently, Scottish firm Nova Innovation was awarded a contract
to install undersea turbines in the Bay of Fundy off the shores
of Nova Scotia. That project is being partially funded by the
Canadian government. Another innovative company, Orbital Marine
Power, says it is developing the world’s most powerful tidal
stream generator. It uses a unique floating platform to support
the turbine below it, eliminating the need for specialized ships
to install the system. Orbital expects the first O2 tidal
turbines to begin operations this year.

Tidal power may not be as well known as wind and solar power,
but as the technology improves it could become an important part
of the world’s clean energy mix.
