- Abstract:
- As the world transitions towards low-carbon energy systems, scaling up clean energy technologies will drive demand for critical minerals and metals, such as lithium, nickel, cobalt, graphite, and rare earth elements. Stakeholders in the private and public sectors must work together to implement effective and efficient strategies, policies, and regulations to ensure that supplies are secure, reliable, sustainable, and equitable. Over the past years, the price volatility of minerals and metals has increased due to rising demand, supply chain disruptions, and concerns about tightening supplies. In addition, today’s markets are highly concentrated in a small number of countries. Although supply diversification investments are increasing, most near-term growth is expected from existing major producers, resulting in an even higher geopolitical risk.1 The transportation sector offers a stark example of these dynamics. Every year, the world increasingly relies on batteries. In 2022, electric vehicles (EVs) accounted for about 10 percent of global vehicle sales and are expected to reach 35 percent by the decade’s end.2 Announced policies around the world are accelerating these trends. For example, recent climate legislation in the United States is deploying billions into battery manufacturing and incentives for EV purchases.3 Lithium-ion batteries, a technology also used in computers and cell phones, power most EVs today. Typical of innovation cycles, years of development and deployment have resulted in significant cost reductions and improved performances. Today’s EVs are becoming increasingly competitive with internal combustion vehicles and can be driven for hundreds of kilometers between charges. Lithium is used in EVs because it is lightweight, has high energy densities, is relatively low maintenance, and can be repeatedly charged. From a market and geopolitical perspective, analysts estimate that lithium demand will increase tenfold before the end of this decade.4,5 In 2021, China dominated lithium global markets with 79 percent of all lithium-ion battery manufacturing capacity; this figure is expected to decrease slightly to around 65 percent by 2025 (see Figure 1).
