The Enel Group and the company Brenmiller Energy, owner of the bGen thermal storage patent, promote the Thermal Energy Storage (TES / Thermal Energy Storage) project, which allows the use of renewable energy resources (wind, solar), as well as residual heat, for heating crushed rocks to very high temperatures.
That heat can be stored for minutes, hours or even days before being used in industrial processes and for power generation. This pilot project is applied for the first time in the world on an industrial scale at the Santa Bárbara plant, in Tuscany (Italy).
The TES system, integrated in the Santa Bárbara plant, will allow Enel and Brenmiller to validate the technology “on the ground, under difficult operating conditions and on a large scale”. According to the Italian company, Thermal Energy Storage will be used “to store excess energy produced by renewable sources in the form of heat.”
The main objective of this initiative is to “offer decarbonisation services to industrial clients and integrate long-term storage solutions with renewable plants”. The system -explained from the company- makes it possible to reduce the start-up times of the plant “and a greater speed in load variations, which are performance requirements necessary to allow the efficient use of renewable energy”.
Brenmiller Energy has developed the technology in Israel and has supplied the storage system; Enel has integrated the system at the Santa Bárbara plant and has contributed to validating its performance in a real environment. The facility has just been inaugurated and the bGen solution is patented: the (fragmented) rock is electrically or thermally charged, and delivers steam or hot air on demand.
