## What Is Driving the Unprecedented Demand for Critical Minerals?
The global transition to clean energy is triggering an unprecedented surge in demand for critical minerals, ultimately fuelling the energy transition and critical minerals debate. According to International Energy Agency (IEA) forecasts, the clean energy transition will require vastly greater quantities of lithium, cobalt, nickel, and other minerals than ever before. In addition, mining’s crucial role in the clean energy transition is becoming a key narrative in policy discussions.
This mineral demand explosion is driven by two interconnected revolutions: electrified transportation and renewable power generation. Moreover, the rising focus on sustainability leads to enhanced scrutiny on raw material supply chains. Decarbonisation in mining and its impact on the clean energy transition provides further insight into how modern energy systems are adapting.
Current trends suggest that the world’s energy transition and critical minerals challenge will shape global markets in the coming decades. Furthermore, the balance between environmental sustainability and economic growth is under intense debate.
## How Will Lithium Demand Change by 2040?
Lithium stands at the epicentre of the clean energy mineral revolution. IEA projections indicate that lithium demand will grow over 40 times from 2020 levels by 2040. Consequently, annual consumption could reach around 4.7 million metric tons compared to 117,000 tons in 2020.
A typical electric vehicle battery requires significant amounts of lithium. In addition, revolutionizing lithium production with CV5 pegmatite is fundamentally altering extraction methods. Each electric vehicle uses around 60-80kg of lithium carbonate equivalent.
This surge in demand is also affecting battery-grade lithium prices. For instance, prices soared from $6,000 per ton in 2020 to peaks of $70,000 per ton in early 2023. Furthermore, experts have noted that every $10,000 increase in an electric vehicle's cost is linked to additional lithium input.
Concurrently, advancements such as direct lithium extraction (DLE) promising lower environmental impacts are receiving increasing attention. In addition, external assessments such as the iea critical minerals report provide detailed perspectives on these trends.
## Which Critical Minerals Are Most Vital for the Energy Transition?

• Renewables need significantly more copper than conventional power plants.
Additionally, innovations in battery chemistries, like Tesla’s 4680 cells and BYD’s blade batteries, are actively reducing some dependencies. Moreover, navigating the critical minerals race amid global resource nationalism offers insight into these complex dynamics.
## How Do Electric Vehicles Impact Critical Mineral Demand?
Electric vehicles (EVs) represent the single largest driver of critical mineral demand growth. An average EV typically requires six times more minerals than a conventional internal combustion engine vehicle.
Battery composition requirements vary significantly across different EV types. For instance, NMC811 batteries are popular in high-range electric vehicles, while LFP batteries dominate the mass-market. Consequently, the distinct mineral demands for each battery type are reshaping global supply chains.
- NMC811: Requires approximately 8kg lithium, 12kg nickel, and 1.3kg cobalt per 100kWh.
- LFP: Needs about 15kg lithium per 100kWh, eliminating the need for cobalt and nickel.
- Solid-state: In development and could potentially halve lithium requirements, while improving energy density.
Furthermore, battery chemistry evolution is significant. The shift towards higher nickel content in NMC batteries has reduced cobalt intensity while increasing nickel demand. This plays a pivotal role in the broader context of energy transition and critical minerals discussions.
Notably, analysts at UBS have warned about potential supply bottlenecks, such as nickel sulfate shortages that may delay large-scale EV production by 2027. In addition, market shifts are driving investments into more sustainable processing methods to ensure long-term supply security.
## What Role Do Renewable Energy Technologies Play in Mineral Demand?
Renewable energy technologies are also substantial drivers of critical mineral demand. Wind turbines, offshore installations, and solar panels each require unique combinations of raw materials to operate efficiently.
Wind turbines, especially offshore, depend heavily on rare earth elements. A typical 3MW direct-drive turbine contains around 600kg of rare earth materials. Larger 10-15MW offshore turbines can incorporate over 2 tonnes of these elements.
Solar panels require silver, silicon, copper, and newer materials like gallium. For example, a 100MW utility-scale solar installation may consume 2-4 tonnes of silver. Additionally, grid-scale lithium-ion batteries, essential for renewable integration, demand vast quantities of multiple minerals.
Infrastructure development for electrification also drives copper demand significantly. The IEA estimates that grid upgrades will require over 70 million tonnes of copper by 2040. Consequently, maintaining a stable supply of energy transition and critical minerals is essential for future networks.
Second-life applications for EV batteries are emerging as an innovative way to boost efficiency. These batteries often retain up to 95% efficiency after a decade of use in grid storage applications. Furthermore, companies like exploring europe’s battery recycling revolution and its opportunities are investing in research that could further optimise these applications.
## What Challenges Threaten Critical Mineral Supply Chains?
The complex supply chains for critical minerals face several interconnected challenges that may jeopardise the energy transition. Geopolitical concentration remains a primary risk. For instance, China dominates processing for lithium, cobalt, rare earths, and natural graphite.
In addition, the Democratic Republic of Congo and Indonesia exert significant control over cobalt and nickel production, respectively. Consequently, these geographical concentrations expose vulnerable points in the chain. Environmental concerns also complicate new developments. Traditional hard rock mining, for instance, consumes more water and generates higher carbon emissions.
Processing bottlenecks add to the problem. While mining capacities are increasing, midstream processing facilities often have long lead times, typically between 5-7 years. Capital expenditure and investment gaps further aggravate the issue, with estimates suggesting that over $400 billion in new investment is required by 2030.
Moreover, stringent regulatory hurdles and lengthy permitting timelines complicate rapid expansion efforts. These challenges highlight why the secure supply of energy transition and critical minerals is such a strategic necessity. In addition, external perspectives such as the irena report on energy geopolitics offer a broader international context.
