In the last decade, the Cobalt has become a strategic mineral for the global economy, occupying a leading place in the manufacturing of batteries for electric vehicles and energy storage systems. The new energy revolution, driven by the urgency to abandon fossil fuels, has skyrocketed demand for critical metals such as cobalt, generating multiple challenges related to their extraction and sustainable management.
The rapid increase in electric mobility and the expansion of renewable energies have made safe and ethical access to this mineral is one of the major concerns of governments, businesses and environmental organizations. It's not just a technological issue, but cobalt is shaping new geopolitical balances already debates on sustainability, human rights and the global ecological transition.
The central role of cobalt in the era of electric batteries
The importance of cobalt lies in its unique properties, which enable the manufacture of high-energy-density rechargeable batteries, such as those used in electric cars, mobile phones, and stationary storage systems for renewable energy. Thanks to its ability to stabilize the chemical structure of lithium-ion batteries, cobalt enables safer and longer-lasting batteries, key factors for the electrification of transport and the integration of clean energy.
At present, Global demand for cobalt is growing rapidly and is expected to continue to rise, especially if the pace of energy transition is maintained. International Energy Agency It is estimated that the global need for critical minerals such as cobalt could quadruple in the coming years, reflecting the magnitude of the challenge.
The global map of cobalt: concentration and dilemmas
La Democratic Republic of Congo (DRC) dominates the 80% of the world's cobalt productionHowever, this heightened prominence is accompanied by multiple environmental, social, and ethical problems. Mining operations often generate community displacement, pollution, and labor exploitation, including documented cases of child labor and human trafficking.
China The United States controls, directly or indirectly, most of the extraction and refining infrastructure in the DRC, consolidating its role as a key player in the supply chain. Other countries such as Australia, Russia, and Canada possess reserves, but their combined capacity falls far short of the DRC's influence, resulting in strong international dependence and limiting the diversification of mineral sources.
For countries like United States and emerging powers, the lack of access to domestic cobalt poses a strategic problem. The situation is complicated by the geopolitical instability, global competition for resources and increasing demands for respect for human rights in the supply chain.
New sources: deep-sea mining and technological bets
Pressure on African deposits has intensified interest in alternative sources, such as Underwater mining in the Clarion-Clipperton area, located between Hawaii and Mexico in the Pacific Ocean. It is estimated that the seabed in that region could hold cobalt reserves far greater than those found on land. Manganese nodules found in this area contain, in addition to cobalt, nickel and copper in appreciable proportions..
Companies such as The Metals Company have begun exploring these riches and claim that deep-sea mining could be done with lower social and environmental impact than traditional land-based mining. However, numerous experts and environmental organizations warn of the potential for severe damage to marine ecosystems, a warning that has led many countries to call for a moratorium on ocean mining until there are sufficient scientific guarantees regarding its sustainability.
On the other hand, research and technological innovation They are seeking alternatives to reduce their dependence on cobalt. Some proposals include improving recycling processes for used batteries and developing new battery chemistries, such as sodium-ion batteries, which could be less demanding on our future consumption of this mineral.
Cobalt in the geopolitical race and the transition to clean technologies
Control over cobalt is strategic for industrial powers. India has intensified its policy of alliances with African countries such as Namibia, Zambia and the DRC to ensure access to deposits of cobalt and other essential metals. At the same time, China continues its Global expansion through direct investments in farms and refineries, which allows it to master both the extraction and the processing and manufacturing phases.
This international competition introduces risks of dependency and vulnerability for the supply chains of key industries such as automotive, electronics, and green energy. Furthermore, the monopoly of certain countries in critical processing stages, coupled with the absence of unified standards for respect for human rights and environmental protection, can create bottlenecks and tensions relevant to global economic security.
Faced with this situation, governments and companies are seeking strategies to secure alternative sources, invest in recycling, and diversify suppliers. The main challenge lies in achieving this without sacrificing commitments to sustainability and social justice, issues that are becoming increasingly important in public opinion and among consumers.
