Lithium demand from storage expected to slow to 5% annual growth

Benchmark Mineral Intelligence projects lithium demand for stationary storage will slow to 5% annual growth through 2030, down from 60% growth over the past two years. The analyst house forecasts global lithium demand reaching 7 million metric tons of lithium carbonate equivalent by 2050, requiring the equivalent of 134 new mines and over $100 billion in investment. Electric vehicles are expected to account for 76% of lithium demand by 2050, up from 55% today, as battery storage deployment moderates. Recycling is forecast to supply almost half of global lithium by 2050. Benchmark did not specify what is driving the slowdown in storage demand.

Where this fits

The storage buildout is already requiring extraordinary material volumes on a scaling trajectory that slows midway through the decade. This signals that the cost and supply-chain constraints of battery-based firming are hitting real limits earlier than transition planners assumed. Australia's grid is betting on stationary storage as the firming backbone for a renewables-only system, yet global lithium supply remains concentrated in three countries and heavily dependent on processing in China. The materials pressure points not at scarcity but at capital allocation, investment volatility, and geopolitical control of the supply chain.

What it means

Slower storage growth means the grid's reliance on gas for weather-dependent firming will persist longer than zero-carbon grids require. Australia cannot secure lithium mining or processing as quickly as the transition assumes, and Chinese refining capacity is already the gating factor. The firming problem Australia faces is real; the material answer to it, firm nuclear power, remains legally off the table.
