In recent years, the global energy and minerals industry has experienced unprecedented growth due to the rapid shift toward electric vehicles, renewable energy storage, and advanced digital technologies. These trends have fueled strong demand for a range of so-called critical minerals, including lithium, cobalt, nickel, and various rare earth elements. Clean energy systems and modern electronic devices often require far larger quantities of mineral inputs than traditional technologies; for example, an electric vehicle can require several times the mineral inputs of a conventional car, and a wind or solar power plant uses many times more mineral materials than a comparable fossil fuel plant. This surge in demand reflects the expanding role of batteries, electric motors, and electronic components in the global economy, transforming minerals once considered niche into essential building blocks for clean technology and digital infrastructure.
Critical minerals are vital for powering batteries, electric motors, and electronic devices. Lithium, cobalt, and nickel are core components of the lithium-ion batteries used in electric vehicles and grid-scale energy storage, determining battery performance and capacity. Rare earth elements are essential ingredients in high-strength permanent magnets that drive electric motors and turbines, and they also play a role in many advanced electronics. Other materials, such as graphite (used in battery anodes) and copper (used in electrical wiring and electronics), also play key roles in clean energy and digital systems. The result is that global demand for these minerals is rising rapidly as the world accelerates toward cleaner energy and more connected technologies.
This rapid rise in demand has highlighted concerns about supply security. The production and processing of critical minerals tends to be geographically concentrated, so disruptions in a few locations can have outsized impacts on the entire supply chain; political changes, trade restrictions, or natural disasters in a key mining region can quickly lead to shortages or price spikes. Developing new mines and processing plants takes many years of investment, permitting, and construction, often a decade or more, so supply often lags behind sudden spikes in demand. For these reasons, securing access to critical minerals has become a strategic concern for governments and companies worldwide.
Meeting rising demand is technically and environmentally challenging, because many critical minerals are difficult to extract and refine at scale. For example, extracting lithium from underground brine or rock can be water- and energy-intensive, and processing nickel or cobalt often involves harsh chemicals and large energy inputs. Mining operations can disturb large areas of land, creating waste rock, tailings, and the potential to pollute local water supplies. Many deposits have declining ore grades, meaning miners must process more rock and generate more waste per ton of metal, which in turn tends to increase greenhouse gas emissions unless offset by clean energy. All of these factors make it challenging and costly to ramp up production quickly while maintaining high environmental and social standards.
In response to these challenges, companies and governments are pursuing multiple strategies, including investing in new mines and processing facilities in diverse regions to avoid over-reliance on any single source. Automakers, battery manufacturers and technology firms are forming partnerships and securing long-term contracts, sometimes even investing directly in mines or processing plants, to lock in material supplies. Recycling and reuse have become priorities as well: new recycling programs aim to recover lithium, cobalt, nickel and rare earths from spent batteries and electronic waste, creating valuable secondary sources. Research and development efforts are also accelerating, focusing on more efficient extraction and processing methods, substitution of scarce materials in batteries and magnets, and other lower-impact technologies. Together, these steps are intended to build a more resilient and sustainable supply chain for the critical minerals that underpin the clean energy transition. |
