Cobalt is used in refineries as a catalyst for the desulphurisation of fuel
Cobalt is a metal with a high selling value. It is used in refineries as a catalyst for the desulphurization of fuel. Catalysts help lower the activation energy for reactions to occur but are not part of the reaction themselves. Hence, cobalt is not present in the fuel that is bought and does not enter the environment.
Cobalt is used in the fossil fuel industry for the desulphurization of fuel. This process, known as hydrodesulfurization (HDS), is a catalytic chemical process widely used to remove sulfur from natural gas and refined petroleum products, such as gasoline, petrol, jet fuel, kerosene, diesel fuel, and fuel oils. The presence of sulfur, even in minute concentrations, poisons the noble metal catalysts (platinum and rhenium) in catalytic reforming units. These units are used to upgrade the octane rating of the naphtha streams. The hydrodesulfurization reaction occurs in a fixed-bed reactor at high temperatures (300-400 °C) and elevated pressures (30-130 atmospheres). The catalyst used in this process consists of an alumina base impregnated with cobalt and molybdenum, known as a CoMo catalyst.
Cobalt is also used in batteries, specifically in the cathodes of lithium-ion batteries, to prevent overheating, catching fire, and extending battery life. The demand for cobalt in batteries has been increasing due to the rise in electric vehicle sales. However, the production of cobalt is associated with dangerous worker exploitation and other serious environmental and social issues, particularly in the Democratic Republic of Congo (DRC), which is the largest producer of cobalt globally.
While cobalt plays a role in the fossil fuel industry, its use in batteries has been a more significant driver of cobalt production growth in recent years. The transition to electric vehicles and the development of cobalt-free batteries present new environmental challenges, highlighting the complex nature of the energy transition.

The use of cobalt in fossil fuels is less than one-tenth of its use in batteries
Cobalt is a mineral that has gained prominence in recent years due to its increasing use in batteries, particularly those used in electric vehicles (EVs). The demand for cobalt has surged alongside the rising popularity of electric cars, which require lithium-ion batteries containing cobalt in their cathodes to prevent overheating and extend battery life. However, the discussion surrounding cobalt often revolves around its mining and human rights abuses, particularly in the Democratic Republic of Congo (DRC), where a significant amount of the world's cobalt is sourced.
While cobalt is indeed used in the fossil fuel industry, its application is minimal compared to its use in batteries. Cobalt serves as a catalyst in refineries for the desulphurisation of fuel. This means that cobalt is not actually present in the fuel itself but aids in the refining process. The use of cobalt in this context is currently less than one-tenth of its volume in battery production, and this proportion is expected to decrease further as battery production continues to accelerate.
The environmental implications of cobalt mining have been a topic of concern. Mining operations, particularly in the DRC, are associated with dangerous worker exploitation, poor working conditions, and other social and environmental issues. Additionally, the production of cobalt emits various types of pollution and contributes to global warming. These concerns have led to calls for a reduction in the dependence on cobalt and the exploration of alternative energy sources.
To address these challenges, governments and companies are considering several strategies. These include diversifying supply sources, innovating battery designs to reduce cobalt consumption or exploring alternative battery types, and increasing the collection and recycling of electronic waste and batteries. While these efforts are underway, it is important to recognize that the transition to new energy sources and technologies may introduce new constraints and complications, emphasizing the need for careful consideration and long-term solutions.
In summary, while cobalt is relevant in the fossil fuel industry as a catalyst, its use is significantly lower than in battery production. The primary concerns surrounding cobalt relate to its mining practices and environmental and social impacts. Addressing these issues involves a multifaceted approach, including supply chain diversification, technological innovations, and a stronger focus on recycling and waste management. As the world navigates the energy transition, it becomes increasingly important to make informed decisions that balance environmental, social, and economic factors to create a sustainable future.

Cobalt mining is associated with dangerous worker exploitation and environmental issues
Cobalt is a key component in batteries that power electric vehicles (EVs). As the demand for EVs increases, so does the demand for cobalt. The Democratic Republic of Congo (DRC) is the world's largest cobalt supplier, producing approximately 74% of the world's cobalt in 2021. However, cobalt mining in the DRC is associated with dangerous worker exploitation and environmental issues.
Cobalt mining in the DRC is often done through ""artisanal" mining, which involves freelance workers using manual tools like pickaxes and shovels to dig in small mines. These artisanal miners are estimated to produce up to 20% of the DRC's cobalt supply, with some estimates reaching as high as a quarter. The conditions in these small mines are often dangerous, with workers facing the risk of accidents, overexertion, exposure to toxic chemicals and gases, and violence. The low pay and gruelling work in these mines have been likened to modern-day slavery, with workers earning just a few dollars a day. Child labour is also prevalent in these mines, with parents sending their children to work instead of school to earn extra income.
The environmental costs of cobalt mining in the DRC are also significant. The mining process produces pollution that contaminates nearby rivers and water sources, and the dust from pulverised rock causes breathing problems for local communities. The southern regions of the DRC, where cobalt is mined, also contain large amounts of uranium, leading to high radioactivity levels. Additionally, the extraction of minerals requires cutting down trees and building roads, negatively impacting the environment and biodiversity.
Some efforts are being made to address these issues. Initiatives like Cobalt for Development aim to support ethical and safer practices in the DRC's cobalt mining industry, with companies like BMW Group, Samsung, and Volkswagen involved. The Fair Cobalt Alliance, joined by Tesla and Glencore, seeks to improve working conditions and end child labour in DRC cobalt mines. While these initiatives are a positive step, there is still a long way to go to ensure that the transition to electric vehicles and renewable energy does not come at the cost of worker exploitation and environmental degradation.

The majority of the world's cobalt is produced in the DRC, where child labour is common
Cobalt is a chemical element used in refineries as a catalyst for the desulphurisation of fuel. It is also used in the production of batteries for smartphones, computers, and electric vehicles. Cobalt is widely used, and the Democratic Republic of Congo (DRC) is a global leader in cobalt production, accounting for over 50% of the world's cobalt reserves.
Cobalt mining in the DRC is associated with dangerous workers' exploitation, environmental issues, and social issues. The majority of cobalt mining in the DRC is done informally, and children routinely work in these mines under hazardous conditions. While mining is on the DRC's list of hazardous activities for which children's work is forbidden, the informal nature of the mines means that monitoring and enforcement are poor.
To address this issue, the DRC government has set up the Inter-Ministerial Commission to Tackle the Issue of Child Labour at Artisanal Mining Sites (CISTEMA) to coordinate efforts to address child labour. Additionally, projects like COTECCO (Combatting Child Labor in the Democratic Republic of Congo's Cobalt Industry) work to support key stakeholders in developing and implementing strategies to reduce child labour and improve working conditions in artisanal and small-scale mines.
Several global big-tech companies have also launched initiatives to support ethical and safer practices in the DRC's cobalt mining industry. For example, BMW Group, BASF, Samsung SDI, and Samsung Electronics launched Cobalt for Development in 2019, with Volkswagen joining in 2020. The initiative aims to make artisanal small-scale cobalt mining more sustainable and improve the lives, work environment, and communities of those involved. Tesla, fearing association with mining firms that access cobalt through child labour, joined the Fair Cobalt Alliance in 2020, which aims to improve workers' conditions and cease child labour in DRC cobalt mines.
The exploitation of children in cobalt mines in the DRC is a serious issue that requires attention and action from governments and companies driving the demand for cobalt.
