What’s stopping even bigger Wind Turbines? Blade speed and flexing? More likely manufacturing and installation capacity

January 18, 2023 by Simon Hogg

Bigger wind turbines make cheaper energy. The sector’s unexpectedly rapid successes in designing and building bigger and bigger turbines has been one of the major success stories of the clean energy sector. In 2023, the biggest turbines in the world will start generating electricity off the coast of the UK. Each of General Electric’s Haliade X turbines stands 260m high from sea level and can generate 13MW at under ÂŁ50/MWh (€56/$61). But how big … [Read more...]

From lab to commercialisation: what is the optimal pathway for Clean Energy Technologies?

January 11, 2023 by Madeline Geocaris and Andrea Wuorenmaa

It’s a considerable challenge to predict, decades in advance, what the world will need and get it from lab to market. Madeline Geocaris and Andrea Wuorenmaa at NREL summarise four case studies that reveal the key elements required: a good balance of technology, R&D, and public-private partnership; regulatory and market force alignment; good timing for market opportunities. The goal is the optimal pathway to the successful first … [Read more...]

New thermoplastic blades for coastal Tidal Energy turbines

September 15, 2021 by NREL

Large-scale tidal power turbines provide an option for clean energy generation that doesn’t depend on the weather, like wind and solar. Research led by NREL is using, for the first time anywhere, thermoplastic composite blades that will improve fatigue performance over typical epoxy blades, can be manufactured faster and more energy-efficiently, and can be recycled. The test site is located in New York City's East River, installed in Verdant … [Read more...]

How to keep winter ice off a Wind Turbine’s blades

March 24, 2021 by Hui Hu

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

May 13, 2020 by NREL

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...]
