[center]Lockheed Martin Cranks Up World’s Largest Wave Energy
Project[/center]
Lockheed Martin, best known for its military aircraft and other
cutting edge airborne machinery, is switching gears in a big
way. The company has signed on with Victorian Wave Partners Ltd.
to engineer a 62.5 MW ocean power project off the coast of
Australia, billed as the world’s largest wave energy project.
The new project will feature a little gizmo we’ve been following
for several years now, the PowerBuoy® wave-powered electricity
generator developed by a company called Ocean Power Technologies
(OPT).
So, let’s see what these guys have been up to since we last
checked in.
The World’s Largest Wave Energy Project – We Built This!
Victorian Wave Partners was formed by OPT’s special-purpose
company, OPT Australasia Pty Ltd., to develop the project.
Lockheed Martin will leverage its experience at the
manufacturing end to get the PowerBuoy components into
production and integrate the wave energy converters.
We first took note of OPT back in 2010, when its small scale
PowerBuoy became the first ever grid-connected wave energy
system in the US.
The hookup took place at a shared wave energy test bed developed
by the US Navy in Kaneohe Bay at Marine Corps Base Hawaii, in
Oahu, where wave energy experiments have been going on since
2003.
If you’re doing the math at home, yes, the test bed goes all the
way back to the Bush Administration, partnering the US Navy with
the Hawaii National Marine Renewable Energy Center.
Scaling Up Wave Energy
The concept behind the PowerBuoy is relatively simple. The shell
of the PowerBuoy is literally a buoy that bobs up and down on
the waves. That produces a mechanical stroking motion, which is
transferred to a converter called a “take-off unit,” which
powers an on-board generator. Electricity from the generator is
conveyed to shore by cable.
That’s all well and good but the next challenge is to scale up
the mechanism into a useful size while maximizing efficiency,
and developing a cost-effective manufacturing stream.
By 2012, the Navy was expanding and enhancing its wave energy
facility, and OPT developed a utility-scale version of the
device.
Aside from scaling up the design, one key efficiency improvement
was the switch from a hydraulic drive take-off unit to a direct
drive unit.
The device is also tunable on a wave-to-wave basis, meaning that
it adjusts to squeeze the most electricity out of each
individual wave.
For extra bonus points, the PowerBuoy only rises about 30 feet
off the surface of the water, with the bulk of its guts resting
below. That low height, relative to offshore wind turbines,
could give wave energy an edge on site selection where aesthetic
concerns come into play.
Although the Australia project is expected to be the world’s
largest of its kind (according to OPT, there’s a potential for
100 MW), let’s note for the record that OPT also has been
testing the Powebuoy off Scotland since 2011, and it is in the
process of commissioning another one off the coast of Oregon.
As for Lockheed Martin, expect more of the unexpected from this
aeronautics firm. As part of a move to rebrand itself as
climate-focused, “smart energy” company, Lockheed Martin also
recently partnered with Concord Blue Energy to commercialize
that company’s high tech waste-to-energy process in global
markets.

[center]The first 3×100 kW WaveRoller pilot power plant built in
2012 [/center]
By Brian Parkin (Bloomberg)
The two-century old dream of harnessing the power of the sea
came closer to commercial reality after the European Investment
Bank backed a Finnish company with ambitions to deploy machines
that generate electricity in six countries.
AW-Energy Oy, which also has the support of the nation’s biggest
utility, Fortum Oyj, said it expects its could sell as many as
300 megawatts of its WaveRollers in the coming years. The EIB on
Wednesday invested 10 million euros ($11 million) in the company
to spur the commercialization of the technology.
Power generated from ocean waves has captured scientific
attention since at least 1799, when the first patents were filed
in France. While scores of demonstration projects have tried
harnessing the sea’s energy, the technology hasn’t yet caught on
at a utility scale because of its expense and technical
difficulty. AW-Energy says its machine using a hinged panel
fixed to the seabed is ready for widespread use.
“The tech is commercially mature,” Chief Executive Officer John
Liljelund said in a phone interview from Brussels, adding that
the machine is due to receive a safety certificate from Lloyd’s
Register this month, increasing its “bankability.”
If it works at a big scale, wave power would generate huge
amounts of electricity without producing greenhouse gases. In
2012, researchers at the German utility EON SE estimated 2.1
terawatts of could be captured along global coastlines. :o ;D
WaveRoller is one of several coastal-power technologies seeking
a broader commercial footing. DCNS SA, the French warship maker,
in 2013 agreed to collaborate with Ocean Thermal Energy Plc on
generating power using differences in sea temperature. Sweden’s
Seabased AB is selling a different near-shore technology based
on floating buoys. Britain and France are working on tidal
lagoons that generate power.
For now, the machines being installed are small. AW-Energy is
about to start a 350-kilowatt unit off the Portuguese coast,
near Peniche, which will form the basis of a 5.6 megawatt
undersea power park using 16 WaveRollers, Liljelund said.
Its objective is to sell more than 50 units in the next four
years. It has plans to install power generators anchored on the
seabeds of six countries.

/>
Under development for almost a quarter century, the WaveRoller
was inspired by a Finnish professional diver, Rauno Koivusaari,
after he observed in 1993 how the power of the sea effortlessly
rocked the hulk of a wrecked ship back and forth.
Tidal Surge
AW-Energy’s WaveRoller harnesses the so-called surge behavior of
waves as they flatten and strengthen when approaching the
shoreline.
AW-Energy is based in 22 kilometers (14 miles) northeast of
Helsinki in Vantaa, Finland. Its other projects in various
stages of planning or execution are located in France, Ireland,
Chile, Mexico and Asia, according to the CEO.
Fortum and DCNS SA in 2013 agreed to install a 1.5 megawatt
demonstration WaveRoller off the Brittany coast. Last year the
company signed an agreement with Mexican clean power developer
Grupo Enal to develop a 10-megawatt wave energy project off the
Pacific coast.

[center]Wave Power Could Contribute 10% Of Global Electricity
Demand By 2050[/center]
June 28th, 2017 by Joshua S Hill
SNIPPET:
More specifically, Marine Power Systems believes that global
wave resources could be worth an estimated 4,000 TWh annually —
or, to look at it another way, total wave resources across the
globe amount to around 80,000 TWh per year, but 4,000 TWh is
economically exploitable. The world’s leading industry body,
Ocean Energy Europe, has predicted that a total of 337 GW worth
of marine power could be sourced by 2050, with a market value
around £76 billion ($97 billion).
Obviously, these are long-term goals, but what is more immediate
and immediately-possible is the role of wave power in Europe.
The report highlights the fact that 45% of wave energy companies
are currently based in the European Union (including the UK),
and with the right financial and policy support over the coming
decades, Europe could exploit an annual market in the range of
€53 billion ($60 billion).

Agelbert NOTE: Wave and tidal power have a lot more potential
than a 10% contribution to global energy supply. WHY? Because of
the physics of planetary rotation and the lunar orbit around our
planet.
I wrote about it some years ago:

Water, Energy and Waste Sustainable Development in Large Cities
[/center]

/>Consumption_files/image002.jpg[/center]
There is no doubt that humans in general, and those concentrated
in cities in particular, are responsible for much of the massive
demand for potable of water and energy. There is also agreement
that this demand is, at present not healthy for the biosphere in
general and humans in particular. There is too much waste,
inefficient energy use, lack of renewable energy infrastructure,
pollution from fossil fuels and inefficient water use as well.
In summary, there is a consensus among knowledgeable and
observant people in the reality based community that our present
trajectory in the above issues is unsustainable.
The solution requires the phasing out of all fossil fuels and
nuclear fission power plants and replace them with Renewable
energy. This energy needs to be harvested within 100 miles or
less from the highest energy users on the planet, the large
cities, in order to have lower transmission and infrastructure
costs.
The energy must be baseload quality 24 hours a day with wind and
solar to supplement demand spikes along with pumped water
storage energy, fuel cell or battery storage technologies.
The renewable energy source that is best suited on a global
scale because it is constant, powerful and close to the major
cities is the energy from ocean currents.
Observe the two maps below.

Now let us overlay the Hydrosphere. ;D
Please observe the result of the merging of the hydrosphere
graphic and the population concentration graphic below:

The energy is renewable, does not disturb the biosphere or
hydrosphere and can completely replace the polluting energy we
now suffer from. The densely populated areas have this powerful
source nearby.
Ocean currents have far more energy potential than ocean tides.
The tides alone are estimated to have a potential tidal stream
energy capacity of over 120GW globally. Using both plus wind and
PV would make a 100% Renewable Energy transition to the 18TW the
planet required feasible with technology we now have.
Just in the UK alone, the marine power resource is estimated to
be more than 10GW, representing about 50% of Europe’s tidal
energy capacity.
In the USA a project is now in the works to provide wind turbine
power to the East Coast for up to 1.9 million households. When
built out, the Atlantic Wind Connection (AWC) backbone will
stretch 350 miles off the coast from New Jersey to Virginia and
will be able to connect 6,000MW of offshore wind turbines.

Now look at where those wind turbines will be and realize that
undersea turbines can be placed close by and save on cabling the
energy to the shore. Much more energy can be harvested 24 hours
a day from the ocean current. Sharing energy transmission cables
from wind and ocean current turbines will save millions of
dollars and hasten the transition to 100% clean energy.

As the new, clean energy replaces dirty energy, full
electrification of the economies to eliminate the internal
combustion engine for power plants, vehicles and factories will
clean the air in large cities.
With plenty of renewable energy to electrify the planet and
eliminate the internal combustion engine pollution, the
worldwide potable water problem can be solved anywhere on the
planet that the relative humidity is above 23% (any place it is
not a desert climate) by extracting water from the ambient air.
The waste water can, given all the ocean current energy, be
processed for agricultural fertilizer (eliminating petrochemical
fertilizers).
In this way, we will imitate the biosphere in turning our waste
into a nutrient that benefits all life on earth, not just
humans.

[center]Wave Power Renewable Energy Project Underway In
Japan[/center]
October 2nd, 2017 by Steve Hanley
SNIPPET:
Professor Tsumoru Shintake of the Okinawa Institute of Science
and Technology University thinks wind and solar power are
wonderful things. But research in those areas is a crowded
field. He wants to investigate other forms of renewable energy,
like turbines driven by ocean currents and waves.
Being a nation of islands, Japan is keenly attuned to the
problem of erosion. Nearly 30% of its coastline is protected
from the ravages of the sea by tetrapods, man-made pyramids that
help reduce the power of waves before they reach the shore.
Professor Shintake and his team would like to redesign those
wave-breaking devices to incorporate small turbines that
generate electricity from the power of the flowing water.
“Using just 1% of the seashore of mainland Japan can [generate]
about 10 gigawatts [of energy], which is equivalent to 10
nuclear power plants,” Professor Shintake explains. “That’s
huge.” It is especially huge in Japan, where nuclear power has a
somewhat mixed track record.
