Abstract
Energy transition pathways have largely treated critical minerals as unconstrained for the deployment of low-carbon energy technologies. This paper challenges this assumption for India, the third-largest energy consumer globally and a major importer of battery-grade minerals, by incorporating lithium supply limitations within an integrated energy-system framework and quantifying the consequences on technology choices, electrification, and transition costs. This study assesses the feasibility of decarbonization pathways using the long-term energy-system models from a critical minerals availability constraints perspective. Using the KINESYS-TIMES model, seventeen scenarios combine three lithium-intensity sensitivities (kg of lithium per kWh of installed battery capacity) with four availability cases (30%, 60% and 90% of unconstrained net-zero requirements, and unconstrained), two dynamic recycling variants, and three runs under an Accelerated Policies scenario of intermediate ambition. The availability is enforced within the optimization; hence the substitutability comes from cost minimization, not from post hoc accounting, and the marginal value of the constraint becomes apparent; Lithium retained in the operational fleet grows twentyfold between 2030 and 2070 from 36.8 to 728.4 kt/yr with post-2040 being the risk period. Under severe constraint, within the fixed lithium-ion technology set modelled, the system reconfigures rather than fails; electrification is throttled back, hydrogen and biofuels expand, and hybrids re-enter endogenously. Recycling contributes little prior to 2045 but increases availability to 452 from 218 kt/year by 2070. The shadow price of the constraint is zero until the cap hits and then increases convexly, in the ratio 1.00: 2.79: 7.94 in 2070 for the three caps, and chemistry innovation delays the cap hit by fifteen years. Under the intermediate ambition, the binding cap is satisfied by 67.9% fossil fuels versus 10.6% under net-zero. These results establish material feasibility as a structurally distinct dimension of India’s net-zero pathway requiring explicit integration into energy planning alongside emissions and energy security.
Summary
Most long-term plans for cutting emissions assume the minerals needed for clean energy technologies (such as the lithium in batteries) will always be available. This study tests that assumption for India, the world’s third-largest energy consumer and a major importer of battery-grade minerals.
Using KINESYS-TIMES, an energy system model, the researchers explored 17 scenarios. These varied how much lithium is available (from 30% of what a net-zero pathway would need up to no limit at all), how much lithium each battery uses, how much is recycled, and how ambitious climate policy is. Because the lithium limits were built into the model itself, it could show how the whole energy system would adapt to a shortage, rather than just adding up the shortfall afterwards.
Key findings:
- Demand rises sharply. The amount of lithium in use across India’s energy system grows about twentyfold between 2030 and 2070, with the greatest supply risk after 2040.
- The system adapts rather than breaks down. When lithium is scarce, the model uses less electrification and turns more to hydrogen, biofuels and hybrid vehicles.
- Recycling helps, but later. It adds little before 2045, but by 2070 roughly doubles the lithium available.
- Costs climb steeply once limits are reached. Shortages cost nothing until the limit is hit, then the cost rises quickly, and much faster under tighter limits.
- Better battery chemistry buys time. Batteries that use less lithium delay the point at which supply runs short by about 15 years.
- Policy ambition shapes the response. Under a less ambitious policy pathway, the gap left by lithium shortages is mostly filled by fossil fuels (about 68%), compared with around 11% under a net-zero pathway.
For policy makers, this research suggests the need to account for mineral supply explicitly, alongside other priorities, so transition plans are realistic and resilient.
