Wind turbine blades are huge, strong and hard to recycle. As the world's use of wind energy grows, researchers are searching for better ways to make use of old, decommissioned wind turbine blades. Now researchers in Denmark are using chemistry to find ways to break down the tough epoxy plastic that make up the blades, and recover useful materials for producing future wind turbines.

Looks promising!

@Petch85 Год назад

Can we maybe repair them and reuse them to make more energy thereby reducing the number of new blades needed?

@ConnorRoss Год назад

i imagine they can design more efficient blades now and so replace them. im sure it all calculated but no doubt there is a lot of waste in most industries.

But ... where is the money in doing that? Follow the .... Money!

@Petch85 8 месяцев назад

@@shabinthegreat I guess when it can work for cars, it can work for wind turbines. You have an old turbine where the blade is damaged, in stead of scrapping the full turbine, you could bay some refurbished blade, maybe with some vortex generators to improve efficiency, og now you can run your turbine for another 10 years or something. Just a you can bay a new set of brakes, shocks etc. for your car.

In my Opinion, just shredding them, running it through an “Entrained Flow Gasifier” then remelt the slag into new fiberglass/rokwool would be more efficient/less complex. Granted I’ll need to watch the video later + read the paper

@user-bu1ix6tg9o 7 месяцев назад

energy use for entrained flow gasifier is very high, and the slag reprocessing would be inhibitivley expensive. gasification is best suited for coal and other less chemically complex organic feedstocks instead of this.

energy intensive not a problem if the reaction occurs in an industrial sized thermos.

"Days" of heat? And where will all that heat come from? (Let me guess - natural gas.) And at what cost?

@Neront90 Год назад

But funding this and building this non-recyclable blades surely feel good.

@justineseman3741 Год назад

so.. turbines are made out of epoxy?

Why exactly would it be a good idea to be shredding old wind turbines to put in concrete (where it will inevitably become microplastics that get dispersed into the environment) and be used for CHILDREN'S PLAYGROUNDS if it intrinsically contains vast amounts of bisphenol-A?? And more importantly, why am I, and not the science journal reporting on these things addressing such an obvious glaring problem?

Because the video is 3:42 mintues long.

@@pablovirus in case you hadn't noticed, there are ten+ hour long videos on here

@pablovirus Год назад

@@Muonium1 you are grossly misunderstanding the purpose of this PR video. It's not MEANT to address every minor detail or possible complaint. There are technical reports and scientific papers for that. You are essentially complaining at the void here.

Unfortunately, "green energies" aren't green yet!

@5eZa Год назад

exactly WHAT CHEMICAL... pointless report. also could you narrate any slower possibly? watch on 1.75 speed. or better yet don't watch at all, for best experience
