CENER experimental wind farm.

Sarriguren (Navarra) December 18, 2019.- Two Researchers in wind energy of CENER (National Renewable Energy Center) are the co-authors of an article that was published in the scientific magazine Science last October with the title: “Large challenges for the science of wind energy ”, in which researchers from 19 international organizations participated.

In this article, led by technicians of the National Renewable Energy Laboratory of  of the United States (NREL) and the Technical University of Denmark (DTU), three major challenges that research should carry out for wind energy to continue being a of the main energy sources worldwide. They consider it necessary to continue with their technological development, so that they can face the energy challenges that arise, while maintaining reduced electricity generation costs, so that it remains competitive.

The origin of this article is a meeting organized by NREL in October 2017 in Boulder (Colorado) in which a group of international researchers from 15 countries participated to discuss and analyze the options of the future electrical system that has wind energy as one of its main sources of clean energy.

During this meeting, in which Xabier Munduate, a researcher from the Wind Energy Department of CENER and the only Spanish representative in this technical meeting, participated, three major challenges were identified in which progress should be made: improving the understanding of atmospheric phenomena and flow of air where the wind turbine operates and by extension the park; improve the aerodynamics, structural dynamics and hydrodynamics of large rotary machines that should not be forgotten that they are wind turbines, and the third challenge would be to optimize the design and operation of wind plants to support and improve the efficiency of the network , its robustness and coupling to changing situations.

For CENER it is important to have been part of this reflection with international experts, since it represents a recognition of the good work developed these years generating knowledge, experience and specialization, thanks to the continuous collaboration that it maintains with the industry of the sector. Developing both analysis tools and conducting custom tests, ranging from scale models to real prototypes.

The main conclusions of this reflection are published in the article of the magazine Science, in whose writing Xabier Munduate and Javier Sanz, researchers from the Department of Wind Energy of CENER participated.
