Union Cabinet to discuss capex support for critical mineral processing, VGF for RE grid-scale storage system

The proposed capital expenditure (capex) support for critical mineral processing addresses a significant bottleneck in India's industrial policy. Critical minerals like lithium and nickel are foundational to the energy transition, serving as essential inputs for EV batteries and renewable energy technologies. By proposing up to 30% support for processing plants, the government is moving beyond raw material extraction to build domestic value addition capabilities. This aligns with broader initiatives like the Production Linked Incentive (PLI) scheme for Advanced Chemistry Cell (ACC) manufacturing, which targets 50 GWh capacity, including 10 GWh for grid-scale storage. From a UPSC perspective, this illustrates the concept of strategic industrial policy—using state support to foster nascent industries vital for economic security and reducing import dependence, particularly from dominant players in the global mineral processing supply chain.

The shift towards securing critical minerals highlights a profound change in resource geography. Unlike fossil fuels, the geographical distribution of critical minerals (and crucially, the capacity to process them) is highly concentrated. India's strategy to incentivize domestic processing of lithium and nickel is a geopolitical imperative as much as an economic one, aiming to mitigate supply chain vulnerabilities. For the UPSC exam, candidates must understand the global distribution of these resources (e.g., lithium in the 'Lithium Triangle' of South America, nickel in Indonesia) and how India's domestic policies, such as the Mines and Minerals (Development and Regulation) Amendment Act, 2023 which opened up critical minerals for private mining, are designed to enhance self-reliance in the face of these geographical constraints.

The proposal for Viability Gap Funding (VGF) for grid-scale storage systems directly addresses the intermittency challenge of renewable energy (RE). Solar and wind power generation fluctuates based on weather and time of day, often leading to a mismatch between supply and demand. The reported curtailment of 1,835 million units (MUs) of RE highlights this inefficiency; power is wasted because the grid cannot absorb it or store it for later use. VGF—a grant provided to support projects that are economically justified but not financially viable—is crucial here. By subsidizing the high upfront costs of grid-scale batteries, the government aims to enhance grid stability and flexibility. This ensures that excess RE generated during peak production periods is stored and dispatched during peak demand, facilitating a smoother transition to a low-carbon energy system, a critical component of India's Panchamrit climate commitments.
