Nearly 800GW of wind power have been installed worldwide so far, with plenty more to come. But the Texas freeze in February showed how vulnerable wind turbines are to ice. Hui Hu at Iowa State University summaries his team’s research into solving a problem that can cut generation by 20% or even shut down turbines completely. He explains why existing de-icing solutions for airplane wings offer only a partial solution. Metal airplane wings can be … [Read more...]
Recyclable Wind Turbine Blades: thermoplastic, next-generation
When wind turbine blades are decommissioned they are usually scrapped and thrown into landfill because they cannot be recycled. In the U.S. over the next four years alone that will be the fate of more than 8,000 blades. As wind installations increase so will that number. It's because most blades are constructed from epoxy or other thermoset resins. So National Renewable Energy Laboratory (NREL) researchers are using a thermoplastic resin, … [Read more...]
