The Italian energy company Eni and the energy storage specialist Seri Industrial have formalized a strategic agreement to develop an integrated industrial supply chain for lithium iron phosphate (LFP) batteries, an initiative that seeks to strengthen European production capacity in a sector considered key to the energy transition.
The agreement was signed through Eni Industrial Evolution and FIB (Fabbrica Italiana Batterie), a subsidiary of the Seri Industrial Group dedicated to the research, development, and manufacturing of LFP battery cells, modules, and systems. The operation is part of the framework agreement announced by both companies on May 16 and is expected to reach definitive closure in the coming days.
Teverola and Brindisi to drive LFP battery production
The alliance contemplates the creation of an integrated industrial platform capable of covering different stages of the battery value chain. These include the production of lithium iron phosphate cells and modules, the assembly of systems for stationary energy storage, and applications intended for industrial and commercial electric mobility.
Furthermore, the project plans to incorporate activities related to battery recycling, the recovery of strategic materials, and the manufacturing of active cathode material in later phases, thereby expanding the industrial scope of the initiative.
Teverola and Brindisi as production centers
Currently, FIB already operates an LFP cell production plant in Teverola, in the province of Caserta. New industrial activities aimed at increasing manufacturing and assembly capacity will be developed at this infrastructure.
For its part, Eni Storage System, a company jointly controlled by Eni Industrial Evolution and FIB, will complete an assembly line for large-scale battery energy storage systems (BESS) between the Teverola and Brindisi centers during the first half of 2027.
Likewise, the companies plan to build a second gigafactory for the production of cells and modules with a capacity exceeding 8 GWh per year by 2029.
Investment of 55 million euros
As part of the operation, Eni Industrial Evolution will acquire a 30% stake in a new company created by FIB, while Seri Industrial will retain the remaining 70%.
The investment includes an initial disbursement of 55 million euros, subject to potential contractual adjustments. The new company will be responsible for the commercial development of the project as well as the engineering and procurement activities necessary for the planned industrial expansion.
Objective: to exceed 10% of the European market
The project relies on the complementary industrial capabilities of both companies and aims to accelerate the growth of European energy storage system production.
The companies estimate that the platform could capture more than 10% of the European stationary battery market, a segment where demand continues to rise due to the growth of renewable energies and the need to reinforce the stability of power grids.
Eni Industrial Evolution was created in January 2026 as part of the industrial transformation process driven by Eni to repurpose production assets and develop new industrial chains based on circular and innovative models. Within this strategy, the company manages refineries, depots, and pipelines in Europe and the Middle East while promoting new activities linked to energy storage and low-emission technologies.
During the announcement, the CEO of Eni Industrial Evolution, Umberto Carrara, highlighted that the agreement strengthens the company’s industrial transformation strategy and contributes to consolidating a supply chain that spans from critical raw materials to the manufacturing of energy storage systems.
For his part, Vittorio Civitillo, CEO of Seri Industrial, noted that the alliance represents a strategic step to reinforce the Italian industrial presence in a market considered fundamental for the European energy transition.
