Materials & Mining Eni is putting $225 million behind EnergyX's Black Giant lithium project in northern Chile, giving the Italian energy company a 25 percent stake in a direct lithium extraction venture that could become a meaningful feedstock source for European batteries. The deal is not only a mining investment. It is a test of whether oil and gas balance sheets can help move lithium supply from brine resource to battery-grade material fast enough for the next wave of stationary storage, EV cells, and regional manufacturing policy.

EnergyX described the same transaction as a strategic investment that supports development of Project Black Giant, one of its largest lithium resource projects. The asset sits near the Salar de Punta Negra in northern Chile, a region already central to global lithium supply. The production plan gives the deal its scale. EnergyX says the project is designed for up to 52,500 metric tons per year of lithium carbonate once fully built. The first phase is expected to target 7,500 metric tons per year beginning in 2028, with full capacity planned by 2030. Those dates still depend on permitting, financing, engineering, and execution, but the output target is large enough to matter for battery supply contracts. Eni's position gives it exposure to future lithium production and a board-level role in the project company. For an oil major, that is a different kind of upstream bet. Instead of adding barrels, Eni is buying into a battery mineral pathway tied to its broader clean-energy and industrial strategy. AI-generated image Direct lithium extraction aims to pull lithium from brine with less reliance on long evaporation cycles. Why DLE Is the Center of the Story Black Giant is built around EnergyX's direct lithium extraction technology. Traditional brine operations often depend on large evaporation ponds, long residence times, and chemistry that can vary by basin. DLE approaches use sorbents, membranes, solvents, or hybrid systems to separate lithium from brine more directly, then return much of the processed brine underground or into a managed circuit. The appeal is clear: faster extraction, smaller land footprint, and potentially higher recovery. The hard part is proving those advantages at commercial scale while controlling water use, reagents, power demand, impurities, and maintenance. Many DLE companies have strong pilot claims. Fewer have shown years of reliable production at the size battery customers need. That is why Eni's investment is notable. Energy companies know subsurface fluids, process plants, large projects, and regulatory scrutiny. If that experience helps EnergyX move from technology pitch to bankable lithium supply, DLE could gain more credibility with automakers, cathode makers, and cell manufacturers looking beyond conventional spodumene and evaporation routes. Why it matters Battery supply chains do not need another lithium announcement. They need projects that can pass permitting, raise project finance, produce consistent material, and sign offtake. Eni's capital makes Black Giant harder to dismiss as a lab-stage story. The European Battery Link The transaction also connects Chilean lithium to Europe's battery ambitions. Eni has been building a wider battery materials and manufacturing position, including plans tied to Italy. A secure lithium stream would help a European industrial player reduce exposure to Chinese refining dominance and volatile spot markets. That does not mean Black Giant will single-handedly change Europe's supply balance. A 7,500 ton first phase is useful but modest against global lithium demand. The larger 52,500 ton target would be more strategic, especially if it reaches battery-grade quality and can be paired with conversion, cathode, and cell production routes that qualify under local content rules. For CurrentCells readers, the key point is that storage demand is making lithium less dependent on the EV cycle alone. Grid batteries, data-center backup systems, and industrial storage are adding a steadier demand layer. That makes upstream lithium optionality more valuable, even after the price slump that punished many miners in 2024 and 2025.

What Could Slow the Project Permitting is the first constraint. Chile is supportive of lithium development but careful about water, Indigenous consultation, state participation, and environmental controls. Any project near sensitive desert and salar systems must prove it can operate without unacceptable hydrological damage. The second constraint is scale-up risk. A DLE process can work in controlled conditions and still face problems when brine chemistry changes, equipment fouls, reagents degrade, or recovery rates fall below model. Lenders and offtakers will want operating data, not only design capacity. The third issue is market timing. Lithium prices have recovered from their lows but remain volatile. If prices weaken again, financing large new projects gets harder. If prices rise too fast, buyers will push for long-term contracts that protect them from another supply squeeze. Black Giant has to navigate both outcomes. AI-generated image Commercial lithium projects are judged by purity, recovery, cost, permits, water performance, and delivery reliability. The Bottom Line Eni's $225 million EnergyX investment is a serious vote for direct lithium extraction, but it is not yet proof that DLE has crossed into low-risk industrial supply. The deal gives Black Giant capital, an experienced energy partner, and a route into European battery strategy. It also gives the market a clear project to watch as DLE moves from promise to execution. If Black Giant reaches its 2028 first phase and then scales toward 52,500 tons per year, it could become one of the more important lithium stories of the decade. If permitting or scale-up slips, it will become another reminder that battery minerals are still mining projects first, technology stories second.
