Eni Pays €55 Million for Stake in Italian Battery Venture

On May 29, 2026, Eni Industrial Evolution — a subsidiary of Italian energy major Eni SpA — signed a formal agreement with FIB, the battery arm of Seri Industrial Group, to jointly develop an integrated lithium iron phosphate (LFP) battery supply chain in Italy, according to Reuters and Rigzone.

Eni Industrial Evolution acquires a 30% stake in a newly created company while FIB retains 70%. The price is €55 million ($64 million), with potential price adjustment mechanisms. The closing deadline was set at five days from announcement — meaning the deal was expected to wrap up by early June 2026, according to Evertiq and ChemAnalyst.

This builds on a framework agreement the two companies signed on May 16, 2026, according to Trend.Az.

Manufacturing Timeline and Facilities

Eni Storage System S.p.A. — a jointly controlled entity already operating — will complete a utility-scale battery energy storage system (BESS) assembly line at the Teverola-Brindisi industrial hub by the first half of 2027, according to Egypt Oil & Gas and Indian Chemical News.

A second gigafactory dedicated to LFP cell and module production is scheduled for completion by 2029, targeting annual output exceeding 8 gigawatt-hours per year, according to Rigzone.

The manufacturing hub is the Teverola facility in Caserta, southern Italy, where FIB already operates Italy's first LFP battery cell production plant. Longer-term plans include battery materials recycling, recovery operations, and production of active cathode materials.

Market Target

The partners aim to capture more than 10% of the European stationary battery market, according to Eni's announcement as reported by Rigzone and Egypt Oil & Gas.

The European stationary storage market is growing as grid operators seek to back up intermittent wind and solar. Chinese manufacturers — led by CATL and BYD — dominate global LFP battery supply. This deal represents an attempt to reduce Europe's dependence on Asian supply chains for batteries critical to its energy transition.

Company Statements

Umberto Carrara, CEO of Eni Industrial Evolution, described the deal as confirmation of Eni's "industrial transformation plan" and said it was "completing the supply chain from critical materials to the production of energy storage," according to Evertiq.

Vittorio Civitillo, CEO of Seri Industrial, said Italy is "finally completing a systemic transaction capable of ensuring a solid and authoritative presence in a strategic sector," per Indian Chemical News.

Unanswered Questions

The deal raises several issues that warrant scrutiny.

Taxpayer exposure: Eni is a state-backed company. The Italian government holds a significant indirect stake through Cassa Depositi e Prestiti. The €55 million investment carries public-sector exposure.

Materials supply gap: Building LFP batteries in Italy does not automatically secure the supply chain. LFP chemistry requires lithium, iron phosphate, and other materials that still flow through Chinese processing. Cathode material production remains a future ambition rather than a current plan.

Timeline risk: A gigafactory by 2029 carries execution risk. European gigafactory projects have a history of delays and cost overruns — Northvolt's implosion in Sweden serves as a cautionary example.

Market share targets: The 10% market share goal requires validation against current market dynamics and competitive positioning.

Implications

If successful, the deal addresses a critical gap: energy storage is essential to any grid running on significant renewable energy. Without domestic battery manufacturing, Europe remains dependent on Chinese supply chains vulnerable to geopolitical disruption or trade restrictions.

The announcement itself is straightforward. Execution over the next three years will determine whether Italian taxpayers see returns on this industrial bet or face another costly lesson in European industrial policy.
