Eni and Seri Industrial Are Building a Battery Supply Chain in Italy. Europe's Energy Storage Gap Is Why.

Most supply chain teams tracking European battery manufacturing have been watching the EV cell story. The more consequential buildout happening right now is in stationary storage, and this week it got a significant new actor.

Eni Industrial Evolution and FIB, part of the Seri Industrial Group, have signed an agreement to jointly develop an integrated industrial supply chain in the lithium iron phosphate battery sector. The initiative aims to create an integrated industrial platform covering the production of LFP battery cells and modules, the assembly of systems for stationary storage applications and for industrial and commercial electric mobility, and, in future perspective, materials recycling and recovery, and the production of active cathode material. 

The financial structure of the deal is specific. Eni Industrial Evolution is acquiring a 30% stake in a newly established company dedicated to commercial development, procurement, and engineering activities, with FIB retaining a 70% stake. The consideration includes a fixed component of €55 million plus price adjustment mechanisms. 

What is actually being built and when

The timeline attached to the investment is the most operationally relevant part of the announcement. FIB will develop industrial activities at the Teverola hub in Caserta, where the first LFP cell production plant is already operational. Eni Storage System, a jointly controlled company of Eni Industrial Evolution and FIB, will complete the assembly line for utility-scale battery energy storage systems at the Teverola-Brindisi hub by the first half of 2027, and a second gigafactory for the production of cells and modules with an output of over 8 GWh per year by 2029. 

8 GWh per year by 2029 is a meaningful number in the European context. The project's stated goal is to capture more than 10% of the European stationary battery market. Europe's stationary battery market is growing rapidly as grid operators, industrial facilities, and renewable energy projects require storage solutions to manage intermittency. The demand is structural and European producers are not currently meeting it at scale.

Why LFP and why now

Lithium iron phosphate chemistry is not the highest-energy-density option available, but it is the most commercially relevant for stationary storage. It is more thermally stable than nickel-manganese-cobalt chemistries, longer-lived across charge cycles, and does not rely on cobalt, a material with a concentrated and politically sensitive supply chain. For grid-scale and industrial applications, these characteristics matter more than energy density.

The European battery manufacturing landscape has been shaped primarily by the EV narrative, with most announced gigafactories targeting automotive-grade cells. The Eni-Seri partnership is explicitly targeting stationary storage, a segment where Chinese producers, led by CATL and BYD, currently dominate European supply. Umberto Carrara, CEO of Eni Industrial Evolution, described the agreement as adding "another piece to the puzzle of completing the supply chain from critical materials to the production of energy storage, leveraging innovative technologies and long-term industrial partnerships." 

The supply chain dimension that goes beyond the announcement

Europe's stationary battery market is currently almost entirely supplied from Asia. The materials supply chain for LFP cells, lithium carbonate, iron phosphate precursors, and electrolyte salts, runs predominantly through China, which controls a dominant share of LFP cathode material production globally. Building a European cell manufacturing base does not automatically localise the upstream supply chain. It creates a new demand centre for materials that are still largely sourced from outside the EU.

For procurement teams in industrial, energy, and infrastructure sectors sourcing battery storage systems for European operations, the Eni-Seri announcement is a signal that a European-produced alternative to Chinese BESS suppliers is being built, with a realistic delivery date of 2027 for assembled systems and 2029 for domestically produced cells. Whether the finished product can compete on cost with established Chinese manufacturers remains the question the market will answer once the gigafactory is operational.

The exposure for European and Asian companies

The partnership lands at a moment when European energy policy, the Iran war-driven energy cost spike, and the EU Tech Sovereignty Package covered in the previous edition of this newsletter are all pointing in the same direction: reducing dependence on non-European infrastructure in categories that sit at the centre of industrial competitiveness. Stationary battery storage is one of those categories. Vittorio Civitillo, CEO of Seri Industrial, noted that "Italy is finally completing a systemic transaction capable of ensuring a solid and authoritative presence in a strategic sector, at a crucial stage of the energy transition."

The disruption does not arrive as a supplier failure or a shipping delay. It arrives as a market where European-sourced alternatives to Chinese supply are moving from announcement to operational reality, and where the procurement decisions made in the next two years will determine which suppliers are positioned when that capacity comes online.
