The Enel Group and Brenmiller Energy Ltd. inaugurated an innovative, sustainable energy storage system in Santa Barbara, Tuscany, in the municipality of Cavriglia (province of Arezzo), in the presence of the President of the Region of Tuscany Eugenio Giani, the Mayor of Cavriglia Leonardo Degl’Innocenti o Sanni, Ambassador-Designate of Israel to Italy Alon Bar, Head of Enel Green Power and Thermal Generation at Enel Salvatore Bernabei, Chief Innovability® Officer of Enel Ernesto Ciorra and Chairman and CEO of Brenmiller Energy, Avi Brenmiller.

The goal of this Thermal Energy Storage (TES) project is to build an innovative thermal storage system in Santa Barbara, which is completely sustainable and capable of accelerating the energy transition.

The integration of the TES system with the existing power plant enables Enel and Brenmiller to test the technology in the field, in challenging operating conditions and on a large scale. The system offers reduced power plant start-up times and greater speed in load variations, which are necessary performance requirements to enable the efficient use of renewable energy.

The system can be used to store excess energy produced from renewable sources in the form of heat to offer decarbonization services to industrial customers and to integrate long-term storage solutions with renewable plants.


“Flexibility and adequacy are two fundamental components of an efficient and reliable electricity system, which can be supplied more and more efficiently by storage,” said Salvatore Bernabei, Head of Enel Green Power and Thermal Generation at Enel. "This trial allows us to validate a family of innovative and sustainable technologies in the segment of long-term storage, which will allow for an ever greater integration of renewables into the grid."

“This solution makes renewables more reliable, flexible and resilient and can be used to decarbonize sectors that need heat at high temperatures,” said Ernesto Ciorra, Director of Innovability® of Enel. “Furthermore, it does not involve any use of rare materials and can be made using stones available in every part of the planet, so it is scalable in a sustainable way everywhere. We thank the colleagues of the Tel Aviv hub for having found it and our Italian colleagues for having implemented it, thanks also to the financial support deriving from the collaboration between the Italian and Israeli governments.”
