About the CIIAE

The Iberian Centre for Research in Energy Storage (CIIAE) is a reference centre dedicated to the advancement of energy storage in all its dimensions.

We drive research, technological development, and real-scale validation to accelerate solutions that enable a more flexible and sustainable energy system. Our work integrates science, engineering, and applied innovation, generating knowledge and technology to address the challenges of the energy transition.

As a next-generation scientific infrastructure, the CIIAE brings together advanced laboratories, pilot plants, and multidisciplinary teams that work in a coordinated manner to transform ideas into scalable solutions. From Extremadura, we contribute to positioning energy storage as a driver of competitiveness, industrial development, and decarbonization in Europe.
