WHAT THE

CUSTOMER

WANTS

TODAY

Increase annual energy production and reduce loading failures to drive down the levelized cost of energy for wind turbines.

The blade is the most influential component of a wind turbine for energy production.

Longer blades, taller hubs are subject to greater structural issues

But as blades get longer, they exert greater loading on the rest of the turbine. And blade design must expand the operational range of the wind turbine to increase energy production without creating other problems. Bigger means optimized designs are a must.

The old paradigm...static designs with longer and longer blades and an insistence on onshore installations...will not serve the customer.

The new paradigm:

 a uniquely optimized and highly controllable blade that boosts efficiency and reduces failures for larger, offshore floating technology.

Atrevida Science's

Active Morphing Blades

with flexible, aerodynamic shells that morph through actuation to achieve optimal shape as wind speed changes.


There are places out in the world, at sea, where winds tend to blow harder and more uniformly above sea level than on land. And these higher wind speeds with low turbulence produce more energy.

 

Our Value Proposition is greatest in these places of huge wind resources…Atrevida Science’s Active Morphing Blade

With 80% of U.S. electricity demand located in coastal states and total offshore wind energy technical potential (2,056 Gigawatts) equal to about double the nation’s demand for electricity, offshore wind energy has the potential to contribute significantly to a clean, affordable,

and secure national energy mix.

Global Offshore Wind Market Set to

Grow Sixfold by 2030

Customer discovery demonstrated wind energy, the largest new green energy, has two major pain points: efficiency (energy production) and failure (maintenance). The cost of wind energy is a significant factor to grow market share. Driving the cost down is accomplished through design innovation that improves wind turbine efficiency and overall system reliability. These drivers are affected by blade design. According to Sandia National Laboratory, the current blade design prevents wind turbines from being used to full potential. Hence, the Department of Energy and the International Energy Agency both emphasize the need for novel rotor design.


During customer discovery, Atrevida Science reached out to experts from the wind industry such as Mikkel Kristensen, the Senior Vice President of Offshore Engineering at Siemens Gamesa (ranked first among the world’s wind turbine manufacturers), Michael Bergey, president of Bergey Wind Power, and Jason Jonkman from the National Renewable Energy Laboratory. All of these individuals agree there is a need for active morphing blades that can adapt their shape to optimal geometry according to wind conditions. Such a blade realizes increased efficiency and sheds loads that are deleterious to the system.


Sandia determined that morphing blades could increase the production of a 1.5 MW wind turbine by 11% and reduce fatigue loads by 70%. Moreover, these loads result in instability issues for floating wind turbines –at a time when the industry is shifting to offshore wind farms!


Atrevida Science is developing active morphing blades (AMB) for wind turbines to target these issues. The AMB has flexible aerodynamic shells that morph through actuation to achieve optimal shape as wind speed changes. Atrevida Science's AMB design offers three main value propositions: efficiency increase (up to 14%, every 1% means 5% return on investment), load reduction (means less maintenance and greater savings in installation costs of up to $95k), and improved stability.
