The Enel Group and Brenmiller Energy inaugurated today a sustainable energy storage system in Santa Barbara, Tuscany.
The TES technology utilizes a two-stage charge and discharge process to provide thermal energy. During the charging phase, steam produced by the Santa Barbara facility passes through pipes to heat adjacent crushed rocks; during the discharging phase, the accumulated heat is released to heat pressurized water and generate steam for electricity. This TES system can store up to 24MWh of clean heat at a temperature of about 550°C for five hours, providing critical resiliency to the power plant.
The collaboration between Enel and Brenmiller came about as part of an Italian-Israeli collaboration protocol aimed at accelerating cooperation between Israeli companies and large Italian industries. The project was partly financed by the Israeli Innovation Authority, which supported Brenmiller with 1 million euros in financing.
