Critical Minerals

Critical minerals are a distinct group of raw materials whose scarcity, concentration in a few jurisdictions, and essential role in high‑technology and clean‑energy systems give them outsized strategic importance. The term, formalised by the United States Department of Energy in 2010, now encompasses roughly 35 elements and compounds—including lithium, cobalt, nickel, rare‑earth oxides, graphite, and phosphates—each of which underpins everything from electric‑vehicle batteries to advanced defense electronics. Their unique supply‑risk profile makes them a focal point of national security, economic competitiveness, and climate‑policy agendas worldwide. ## Definition and Scope The United States DOE’s 2022 “Critical Minerals List” enumerates 35 items, while the European Union’s 2023 Critical Raw Materials Act recognises 30, with 22 overlapping across the two lists. Lithium‑ion batteries alone require three of the most contested minerals—lithium, cobalt, and nickel—accounting for 60 % of the total material cost of a 75 kWh pack in 2023. The International Energy Agency estimates that global demand for lithium will rise from 100 kt in 2023 to 2.5 Mt of lithium carbonate equivalent by 2030, a 25‑fold increase driven by electric‑vehicle (EV) adoption. Rare‑earth elements (REEs) such as neodymium and dysprosium, essential for permanent‑magnet motors, contributed $9.5 billion to global trade in 2022, reflecting their high‑value niche. ## Historical Evolution The concept emerged in the early 2000s when the United States identified a “strategic vulnerability” after China supplied over 80 % of the world’s REEs in 2010. In response, the US enacted the Energy Policy Act of 2005, which mandated the Department of Energy to publish a critical‑minerals list—a practice continued annually. The European Union followed with its 2020 “Critical Raw Materials” communication, later codified in the 2023 Act that obliges member states to develop domestic extraction and recycling capacities. India entered the arena with its National Mineral Policy of 2019, which earmarked “critical minerals” for focused exploration and created the Ministry of Mines’ Critical Minerals Division in 2021. ## Supply Chains and Geopolitics As of 2023, the Democratic People’s Republic of Korea, Australia, and Canada together supplied 70 % of the world’s cobalt, while the Democratic Republic of Congo produced 70 % of global cobalt ore but accounted for only 15 % of refined cobalt due to limited downstream capacity. China’s share of global lithium processing stood at 55 % in 2022, despite holding just 30 % of lithium‑bearing brine resources. The United States imported 90 % of its REEs in 2022, prompting the 2021 Critical Minerals Supply Chain Resilience Act, which earmarked $2 billion for domestic mining and processing projects. These concentration patterns have spurred “resource nationalism,” illustrated by Indonesia’s 2021 ban on raw‑nickel ore exports to force downstream smelting within its borders. ## Policy Framework The United States’ 2021 Critical Minerals Policy Act created the Office of Critical Minerals within the Department of Energy and authorized $3 billion in tax incentives for domestic extraction, recycling, and strategic stockpiling. The European Union’s 2023 Act introduced a “green‑by‑design” requirement for mining projects, mandating a 30 % reduction in water consumption compared with 2020 baselines. India’s 2022 “Strategic Minerals Policy” set a target of achieving 30 % self‑sufficiency in lithium and 20 % in REEs by 2030, and established a public‑private partnership model overseen by the Indian Strategic Minerals Fund, which received an initial capital infusion of ₹10,000 crore. Internationally, the 2022 International Partnership on Critical Minerals, co‑led by the US, EU, Japan, and Canada, pledged $10 billion for joint exploration in Africa and the Pacific. ## Current Challenges and Future Outlook Despite policy momentum, the 2024 Global Critical Minerals Outlook reports that only 12 % of projected 2030 demand for battery‑grade lithium can be met by existing mines, leaving a supply gap of roughly 1.2 Mt. Recycling rates remain low: the International Recycling Forum recorded a 5 % recycling rate for lithium‑ion batteries in 2023, compared with 30 % for lead‑acid batteries. Substitution research, such as sodium‑ion battery development funded by the US Department of Energy’s $150 million Battery 2030+ program, aims to reduce reliance on lithium but faces performance trade‑offs. Meanwhile, geopolitical tensions—exemplified by the 2022 US‑China trade restrictions on rare‑earth processing equipment—underscore the need for diversified, resilient supply chains.
