Wind Generators Repurposed — FUD Dispatched!


One of many enduring items of FUD misinformation that circulates within the miasma of the web is that wind generators (and different supplies which can be used for renewable vitality technology) will find yourself within the landfill and destroy the Earth — a lot worse than coal, clearly.

Like all FUD, there may be some reality on this. Early wind generators are beginning to get replaced by newer, larger, and extra environment friendly fashions. The towers and motors are straightforward, the blades are the problem. “Blades are one of many hardest issues on a wind turbine to recycle,” says Katrina Swalwell, a wind engineer and technical director at Aurecon, an engineering consultancy that’s been energetic within the wind business since its inception in Australia. “They’re fibreglass, usually with various structural elements in there as effectively,” she provides.

“Australia presently has no amenities for recycling fibreglass, leaving the turbine blades hanging within the proverbial air. Because the time approaches for the earliest Australian wind generators to be decommissioned, options are wanted to keep away from the blades and different elements turning into a part of landfill.”

What can we do with the decommissioned wind generators?

An revolutionary step has been taken by Superior Power Sources — used wind turbine blades have been sourced from Holland and imported into Australia. The wind generators have been shipped after which trucked to the West Australian outback to assist energy AER’s microgrid, supplying energy to Moora companies.

Based in 2006, Superior Power Sources (AER) is a various West Australian energy generator, electrical energy retailer and vitality firm with intensive expertise within the growth, building and operation of renewable vitality turbines,” the corporate writes. “AER is a part of the Castelli Group which has a proud historical past of being WA owned and operated for over forty years. Every of our enterprise sectors are pushed by a give attention to high quality, integrity and sustainability, and are backed by the power and integrity of the Castelli Group and a confirmed and numerous observe document which units us other than different vitality corporations.”

Clear Power Future Fund funding has been vital to the mission’s success. The Castelli Moora Microgrid hybrid energy station might be funded by West Australia’s Clear Power Future Fund to the tune of $1.8 million. The mission will encompass a biomass, wind, and battery microgrid incorporating current photo voltaic PV and serving a piggery and citrus farm, and doubtlessly different farms within the Moora district.

“The gorgeous nation city of Moora is located on the banks of the Moore River within the Wheatbelt Area of Western Australia,” the city itself writes. “It’s surrounded by spectacular Salmon Gums, stunning parks, gardens and heritage buildings and is a well-liked stopover for vacationers following the Wildflower Path. The shire is central to quite a few sights within the Midlands together with coastal cities similar to Jurien Bay and Lancelin. The Pinnacles within the Nambung Nationwide Park at Cervantes can be a serious drawcard. The Moora city website is barely 55 km from the Benedictine Monastery city of New Norcia which additionally attracts many vacationers.” Certainly, Majella and I’ve pushed by the realm — about 10 years in the past — and might attest to its magnificence. It’s a few hours north of Perth. In 2021, the city had a inhabitants of about 1800.

“Moora lies inside the Moora Vital Chook Space, declared by BirdLife Worldwide as a result of it helps as much as 60 breeding pairs of the endangered Carnaby’s Black Cockatoo,” Wikipedia notes. “Surrounding the city are a number of rural actions (such because the rising of wheat, barley, canola, oaten hay and lupins, in addition to the elevating of sheep, cattle and pigs) and a silica mine situated 15 km north of the townsite.”

Luca Castelli lately posted a video of the transport of the wind turbine blades to Moora on LinkedIn. You may watch it right here:

In case you can not see the LinkedIn put up above, he feedback: “Over a number of weeks, Moora microgrid’s 4 refurbished 1.8MW Enercon E66 wind generators have been travelling to website following the ocean voyage from their earlier house within the Netherlands. See how a single blade nearly 35m in size makes its manner from Perth to its new house in Moora/Dandaragan. Following a profitable wind farm supply of 5 refurbished 0.5MW Enercon E40 wind generators at Port Gregory (close to Kalbarri, WA) AER has managed all elements of the dismantling and recommissioning of Moora’s 4 generators. Moora microgrid will quickly start supplying renewable vitality to native vitality customers within the Dandaragan/Moora space as a 7+MW microgrid incorporating wind, PV, biogas, battery storage and nearly 50km of personal HV community.” That is the fruits of six years of labor.

The reference to the Port Gregory operation refers to a earlier set up to energy a garnet mine. Port Gregory is located about 500 km north of Perth. Right here, 5 refurbished wind generators energy GMA’s industrial garnet mine.

GMA Garnet Group describes itself because the trusted international chief in industrial garnet, supplying garnet for abrasive blasting and waterjet reducing. It provides 600,000 tons of garnet per 12 months to over 80 international locations. The corporate has 40 years of expertise and 450 staff globally.

“As the one vertically built-in garnet abrasive provider, GMA produces rigorously examined merchandise at scale whereas minimising the potential for provide chain disruption.”

Sadly, not this type of garnet. Photograph courtesy of Majella Waterworth.

AER might have found a wealthy vein of curiosity in utilizing older know-how to energy hybrid vitality farms. West Australia is dry and heat, and so there needs to be little degradation of the tools imported. It might be fascinating to search out out the associated fee to dismantle an current wind turbine, ship it to Australia, after which refurbish and presumably improve to Australian requirements. Maybe readers would possibly prefer to remark. And the way a lot life can be left in such a tool? I count on AER would have labored out the associated fee and return-on-investment (ROI) ratio.

Apparently, within the UK, you should buy a 10-year-old dismantled 500 kW wind turbine with further elements for below £40 thousand, nearly scrap worth as a result of the business has moved to far bigger fashions. Excessive disposal prices may also encourage the sale of older wind generators at decrease costs.

I’d like to have one among these in my yard!

It appears to be like like a second-hand market is forming and AER (and different corporations) will take benefit, setting them up in Australia’s distant areas to interchange the diesel that’s presently getting used and to complement the photo voltaic that’s already put in. The query could also be, is it cheaper to place in batteries or second-hand wind generators? As wind generators are changed in additional mature markets, these second-hand generators might assist the newer markets in the least developed international locations to maneuver in the direction of wind, as they’ve completed for photo voltaic.

Does this imply that there aren’t any landfill points, in any case? Has yet another piece of FUD been dispatched? Not but, however the tasks undertaken by AER give hope {that a} viable answer is pending.


 




I do not like paywalls. You do not like paywalls. Who likes paywalls? Right here at CleanTechnica, we applied a restricted paywall for some time, but it surely at all times felt incorrect — and it was at all times robust to determine what we should always put behind there. In concept, your most unique and greatest content material goes behind a paywall. However then fewer individuals learn it! We simply don’t love paywalls, and so we have determined to ditch ours.

Sadly, the media enterprise continues to be a troublesome, cut-throat enterprise with tiny margins. It is a endless Olympic problem to remain above water and even maybe — gasp — develop. So …
