Brindisi, 6 July 2026 – Eni Storage Systems, a company jointly owned by Eni Industrial Evolution and FIB (Seri Industrial Group), today launched construction works at the Brindisi industrial site for the development of a new integrated Italian and European hub for the production of lithium-iron-phosphate (LFP) batteries. The batteries will primarily be used for Battery Energy Storage Systems (BESS) that support the deployment of renewables and enhance grid stability. These systems store energy generated from renewable sources when production exceeds demand and release it when needed, making them essential to overcoming the intermittency of renewables. European demand for such systems is expected to grow from 36 GWh in 2025 to around 138 GWh by 2030*.
Today, an official groundbreaking ceremony for the first integrated hub dedicated to the production of stationary batteries was held in an area of the Versalis industrial site that was formerly used for polymer storage and other industrial activities that have long since been decommissioned. The ceremony was attended by Italy’s Minister of Enterprises and Made in Italy, Adolfo Urso, together with local authorities.
Eni Storage Systems’ development plan includes the construction of a gigafactory in Brindisi for the production of battery cells and modules, together with a Battery Energy Storage System (BESS) assembly plant. The latter will have an expanded capacity, enabling it to assemble battery modules also supplied by Seri Industrial’s gigafactory in Teverola, in the province of Caserta. To complete the project, in the second phase the Brindisi site will also host the production of lithium-iron-phosphate (LFP) cathode active material and battery recycling activities, both built to serve the two gigafactories. The project envisages a total production capacity of 16 GWh per year by 2030 (half in Brindisi and half at the Teverola plant), equivalent to more than 10% of the European market for stationary energy storage systems (BESS).
“Today, we are launching in Brindisi an industrial initiative that marks Eni’s entry into an entirely new business with significant growth potential. This project is designed to support the energy transition by creating industrial and technological value in a sector that is crucial to the decarbonisation process, combining the development of renewables with the resilience of the energy system. This investment will establish an innovative local value chain capable of generating employment and strengthening strategic autonomy from non-EU markets, while reducing emissions without compromising competitiveness. Our industrial transformation model, which combines greater environmental sustainability, economic competitiveness and energy security, is now a tangible reality. It is further strengthened by Eni’s investment in FAENIX, the Seri Industrial Group company, made in parallel that will market the energy storage systems produced in Teverola and Brindisi”, said Giuseppe Ricci, Eni’s Chief Operating Officer for Industrial Transformation.
“Periods of profound transformation require courage, vision and the ability to recognise when certain industrial models are no longer sustainable. When the answer is investment in an innovative, competitive business that is central to the global energy transition, we are proud to be part of it. When change is driven by a strong industrial vision, social responsibility and the awareness that we must work together as a country, we are confident that this initiative will become an extraordinary opportunity for growth for Brindisi and for Italy”, said Vittorio Civitillo, Chief Executive Officer of Seri Industrial and of FAENIX.
