THE Offshore Wind Thread (merged)

[skiptamali]

Does anyone here have extensive experience in wind turbines?

I do. What's up?

How feasible is it to put them 15+ miles off US coastlines? Is the technology there? What happens if a hurricane hits? What's cost of installation & maintenance like? Lifespan on an offshore windmill?

Glad you showed up.

How feasible is it to put them 15+ miles off US coastlines?

It depends on the soil condition. The Atlantic is still very shallow 15 miles offshore, whereas the Pacific can be significant deeper. The shallower the easier.

Is the technology there?

Generally yes, but the problem is not the technology; it's our insane and unstoppable demand for energy. Also, it doesn't work to produce electricity offshore Florida and transmit it 2,000 miles to Minnesota.

What happens if a hurricane hits?

Some blades may break, it may cause excessive stress to the tower, perhaps the foundation, but if they fall, nobody will be hurt and it is easily salvable.

What's cost of installation & maintenance like?

I can't give details, but slightly higher installation cost than land-based, with perhaps less wear and tear on the clutch and gearbox because of the steadier wind regime.

Lifespan on an offshore windmill?

About 30 years.

Glad you showed up.

Glad to serve. Let me know if you need anything else.

Offshore wind farms is far from a theory in Texas (largest producer of onshore wind generated e in the US). Some time ago the state awarded, after competative bidding, offshore wind farm leases off the coast of south Texas. Now that the winners have the right it will be interesting to see if they can finance the follow through. Maybe V knows something about the winners.

Looks like we'll be leading the nation in offshore wind farm development now too. As well as drilling more wells: this weeks lease sell brought in over $450 million in lease bonuses for the Feds.

Thanks for the credit. Alas, I didn't participate in those deals. Offshore wind is great, but only goes so far. I'm sure you can inject into ERCOT South, and thus into all ERCOT --constraints permitting--, but evidently it will not go outside ERCOT. Off Beaumont/Port Arthur you can sell into Entergy, and that's about it.

V,

It will be intersting to see if the offshore players snag the state like ole Boone did. You do know that he didn't have a buyer for most of his w Tx wind output? Last month the state PUC authorized a $4.5 billion line to haul his juice to Dallas. That's why he got the land so cheap: no competiton. Who would build a wind farm where there's no market for the output? And they're still growing the feed grass and running the cattle under the turbines. How's that for being green.

Damn...I wish I had as much smart as Boone has in his little finger.

I find it hypocritical that a man who made so much money on feeding America's addition to oil, puts out a massive plan to cut the addiction, will make even more money on the solution, and will come out as the savior. Outrageous!

Today, a revolutionary British design that mimics a spinning sycamore leaf and which was inspired by floating oil platform technology, entered the race. Leading engineering firm Arup is to work with an academic consortium backed by blue-chip companies including Rolls Royce, Shell and BP to create detailed designs for the "Aerogenerator", a machine that rotates on its axis and would stretch nearly 275m from blade tip to tip. It is thought that the first machines will be built in 2013-14 following two years of testing.

Deepwater Wind Submits Bid For 1 GW Offshore Wind Project

Deepwater Wind has officially submitted its plan to develop a utility-scale offshore wind farm off the coasts of Rhode Island and Massachusetts.

The bid comes in response to the U.S. Department of the Interior's Bureau of Ocean Energy Management Regulation and Enforcement's (BOEMRE) call for information and nominations for offshore wind energy projects in the federal ocean waters off southern New England.

As planned, Deepwater Wind's project - the Deepwater Wind Energy Center (DWEC) - will have a capacity of approximately 1 GW and will serve as a regional offshore wind energy center serving multiple states on the East Coast.

DWEC will be sited in the deep ocean waters of southern Rhode Island Sound, where it will be barely visible from the shore, Deepwater Wind explains. Construction is expected to begin in 2014 or 2015, and the first wind turbines are planned to enter operation by the end of 2016 or 2017.

Global Wind Power: The Chart

A while back I promised some charts based on the BP Statistical Review of World Energy. So, for your geeky viewing pleasure, I’ve created a “motion chart” that tracks global wind power installations, from 1997 through 2010.

Click here to see the wonktastic “motion chart.” It takes a few moments to load, so be patient. And once it loads, feel free to play with it a bit to get a feel for the numbers. The vertical axis of the chart represents per capita wind power installed in various countries, and the horizontal represents total wind power.


Third, the US—sometimes called “The Saudi Arabia of Wind“—led the world in total wind power capacity in 2008 and 2009. But in 2010 the US lost its overall lead to China. The US still beats China in terms of wind power per capita. But despite the surge in interest in renewable power in the US, China came on strong in 2008 through 2010, with massive, rapid deployment of wind power that rocketed the Asian giant into a position of global leadership.

Offshore wind investment could reach €17bn by 2030

Europe's offshore wind industry could be investing €10.4bn in turbines annually by 2020, growing to €17bn by 2030, according to a new report from the European Wind Energy Association (EWEA).

Published yesterday, the EWEA offshore wind supply chain report (PDF) predicts that the nascent sector will grow tenfold in the next decade, delivering 40GW of installed capacity by 2020 and meeting more than four per cent of the EU's total electricity demand.

Under that deployment scenario, annual investment in offshore wind turbines could reach €10.4bn a year by 2020, creating 169,000 jobs.

The report predicts that capacity could then potentially reach 150GW by 2030, supplying 13.9 per cent of total EU electricity demand, and driving investment of €17bn a year in turbines.

Many of the projects are planned in north west Europe, particularly UK, German and Belgium waters. The UK currently has around 45 per cent of Europe's total offshore wind capacity, and is planning to build another 47GW.

According to the report, 18 European countries will have some offshore wind capacity by 2020.

Energy Department Announces New Investments in Pioneering U.S. Offshore Wind Projects

Underscoring the Obama Administration's all-of-the-above strategy to develop more secure domestic energy sources and strengthen American competitiveness in the global market, U.S. Energy Secretary Steven Chu today announced seven offshore wind awards for projects in Maine, New Jersey, Ohio, Oregon, Texas, and Virginia. As part of the Energy Department's broader efforts to launch an offshore wind industry in the United States, these engineering, design, and deployment projects will support innovative offshore installations in state and federal waters for commercial operation by 2017.

"The United States has tremendous untapped clean energy resources, and it is important for us to develop technologies that will allow us to utilize those resources in ways that are economically viable," said U.S. Secretary of Energy Steven Chu. "Today's announcement of awards to the first offshore wind projects in the U.S. paves the way to a cleaner, more sustainable and more diverse domestic energy portfolio that develops every source of American energy."

Offshore wind represents a large, untapped energy resource for the United States—offering over 4,000 gigawatts of clean, domestic electricity potential, four times the nation's current total generation capacity. According to a new report commissioned by the Energy Department, a U.S. offshore wind industry that takes advantage of this abundant domestic resource could support up to 200,000 manufacturing, construction, operation, and supply chain jobs across the country and drive over $70 billion in annual investments by 2030. Offshore wind represents an economic and energy opportunity that could mirror the success of land-based wind development.

$4 Million “Superwire” Could Blow The Offshore Wind Power Market Wide Open

Researchers at the University of Houston have just won a new round of funding for a $4 million wind power project that is on track to solve a key wind energy transportation conundrum: how to use superconducting wire without running afoul of the magnetic field generated by wind turbines. The new grant of $900,000 from the Department of Energy comes on top of two earlier DOE grants totaling $3.1 million. If the project is a success, it will lead to the commercial production of low-cost superconducting wire for wind turbine generators, and that will open up the field for low-cost wind power, especially offshore wind turbines.



So far, the three-year project has far outpaced expectations. The end goal is to achieve a 400% performance improvement in superconducting wire, with an interim goal of 50% by the end of 2012.

The team beat the interim goal by a wide margin, achieving a 65% gain by the end of September.

The pace of progress was apparently so promising that ARPA-E, the advanced energy research agency that administers the grant, accelerated the grant disbursement ahead of schedule.
