What You'll Learn
Cobalt is not a fossil fuel
Cobalt is used in refineries as a catalyst in the production of low-sulfur fuels. It is not a component of the fuel itself but rather facilitates the chemical process of removing sulfur from the fuel. This is an important distinction to make because it means that cobalt is not released into the environment when the fuel is burned. In fact, cobalt catalysts can be recycled and reused, reducing waste and environmental impact.
Cobalt has gained prominence in recent years due to its increasing use in batteries, particularly in electric vehicles (EVs). The demand for cobalt has surged with the rise in EV sales, and the Democratic Republic of Congo (DRC) is the world's largest supplier, producing up to two-thirds of the world's cobalt. However, cobalt mining in the DRC is often associated with dangerous working conditions, child labour, and other serious environmental and social issues.
The use of cobalt in batteries has sparked debates about the environmental impact of EV technology. Critics argue that the mining and disposal of cobalt-containing batteries contribute significantly to pollution and that transitioning to EVs may simply shift environmental problems rather than solve them. However, it is important to note that cobalt mining for batteries emits less pollution than traditional fossil fuel extraction and combustion. Additionally, advancements in recycling technologies may eventually allow for the recovery of up to 95% of raw materials from batteries, mitigating some of the environmental concerns.
In summary, cobalt is not a fossil fuel, but its role in the fossil fuel industry and its increasing use in EV batteries have brought it into the spotlight. While cobalt mining and the social and environmental issues surrounding it are causes for concern, the wider use of cobalt in low-carbon technologies may ultimately contribute to reducing dependence on fossil fuels.

Cobalt is used in batteries, not fuel
Cobalt is a mineral that has gained prominence due to its increasing use in low-carbon or green technologies, such as rechargeable batteries and magnets in wind turbines. It is especially critical in the cathodes of lithium-ion batteries, where it helps prevent overheating, catching fire, and extends battery life. This makes it an essential component in electric vehicles (EVs), consumer electronics, and renewable energy infrastructure.
While cobalt is indeed used in the fossil fuel industry, its application is as a catalyst in refineries for the desulphurisation of fuel. This means that cobalt itself is not a fossil fuel and is not present in the fuel that we use. Instead, it facilitates the process of making fuel cleaner by removing sulphur. Importantly, these cobalt catalysts are recyclable, and refiners have been recycling them for years.
The primary use of cobalt is in batteries, with the steep rise in its production driven by the surge in electric vehicle sales and the demand for lithium-ion batteries. In 2021, EVs were the biggest consumers of cobalt, and batteries for other consumer products were close behind. From 2020 to 2021, 85% of cobalt growth was attributed to lithium-ion batteries. This trend is expected to continue, with battery production far outpacing the use of cobalt in the fossil fuel industry.
The issue of cobalt use in batteries versus fossil fuels is nuanced. While cobalt mining is associated with dangerous worker exploitation and environmental concerns, the pollution caused by mining does not reach the levels associated with traditional fossil fuels. Additionally, as the world transitions to electric vehicles, the focus should be on reducing our dependence on all types of vehicles and investing in alternative energy sources. Developing cobalt-free batteries and addressing the environmental impact of tyre manufacturing and disposal are also crucial considerations.
In conclusion, while cobalt is used in both batteries and the fossil fuel industry, its primary application is in batteries, especially for electric vehicles. Cobalt is not a fossil fuel, and its use in refineries as a catalyst does not mean it ends up in the fuel we use. The discussion around cobalt highlights the complexities of the energy transition and the need to address multiple environmental and social issues.

Cobalt mining causes environmental and social issues
Cobalt is a key component in the renewable energy transition, powering electric vehicles (EVs) and batteries. The Democratic Republic of Congo (DRC) is the world's largest cobalt supplier, accounting for around 70% of global production. However, cobalt mining in the DRC has been associated with serious environmental and social issues.
Firstly, cobalt mining has led to environmental degradation and pollution. The southern regions of the DRC, where cobalt is mined, also contain large amounts of uranium. This has resulted in high radioactivity levels in mining regions, posing risks to local communities and the environment. Additionally, cobalt mining produces pollution that contaminates nearby rivers and water sources. The dust from pulverised rock has been linked to breathing problems and increased risks of birth defects in local communities. The use of blasting and electricity in the cobalt extraction process contributes to global warming and eutrophication, with carbon dioxide and nitrogen dioxide emissions being particularly high.
Secondly, cobalt mining in the DRC has been associated with dangerous workers' exploitation and human rights abuses. The majority of the DRC's cobalt is produced through "artisanal" or small-scale mining, where individuals work independently without formal employment in a mining company. These artisanal miners often face poor and unsafe working conditions, with reports of modern-day slavery, human trafficking, and child labour. While industrial mines have some safeguards in place, the dividing line between industrial and artisanal mines is blurry, and it is challenging to trace the supply chain back to its origin.
The increased demand for cobalt due to the rise in electric vehicle sales and battery production has exacerbated these issues. To meet this demand, mines, both legal and illegal, have been appearing throughout the DRC, threatening the nation's biodiverse tropical rainforest. The pressure on cobalt supply has also led to human rights abuses and the exploitation of unregulated artisanal miners.
Addressing these environmental and social issues is complex. While some suggest stopping cobalt mining altogether, this is challenging in a society heavily reliant on cobalt. Instead, reducing cobalt demand in batteries through recycling, repairing, and redistributing electric goods can help. Additionally, investing in alternative energy sources and decreasing our dependence on vehicles, whether electric or fossil fuel-driven, could provide a more radical long-term solution.

Cobalt is recycled, not burned into the atmosphere
Cobalt is a mineral that has been in the spotlight in recent years due to its increased use in electric vehicle (EV) batteries. The Democratic Republic of Congo (DRC) is the world's largest cobalt supplier, producing almost 70% of the world's cobalt in 2022. The steep rise in cobalt production is driven by electric cars and batteries for other consumer products.
Cobalt is not a fossil fuel, but it is used within the fossil fuel industry as a catalyst in refineries for the desulphurisation of fuel. Cobalt is not burned and released into the atmosphere during this process. Instead, it is recycled into fresh catalysts and specialist materials. The recycling of cobalt leads to a significant reduction in energy consumption, water use, and emissions of greenhouse gases and sulfur oxides.
The use of cobalt in the fossil fuel industry is relatively small compared to its use in battery production. However, the production and use of cobalt are associated with environmental and social issues. Cobalt mining in the DRC is often carried out by unregulated, artisanal miners working under poor and dangerous conditions, with child labour being common. The extraction process also has negative environmental impacts, including high carbon dioxide and nitrogen dioxide emissions.
To address these issues, there is a growing focus on recycling cobalt. Cobalt is endlessly recyclable in principle, and materials containing cobalt, such as batteries, are increasingly being recycled back into the supply chain. By 2050, it is estimated that around 25% of the required cobalt could be supplied from secondary sources through recycling.
In conclusion, cobalt is not burned into the atmosphere but is recycled, particularly in the context of its use in the fossil fuel industry. The recycling of cobalt has important environmental benefits and helps to reduce the negative impacts associated with cobalt mining and production.

Fossil fuel refinement causes pollution
Cobalt is a mineral that is essential to the transition to renewable energy sources. It is a key component of batteries, which power electric vehicles (EVs). However, cobalt mining is associated with environmental and social issues, including the environmental problem-shifting caused by transitioning to electric cars.
While cobalt is not a fossil fuel, its use in the fossil fuel industry contributes to pollution. Fossil fuels are the primary source of energy for electricity and industrial processes, and their refinement and consumption cause significant environmental damage. The refinement of fossil fuels, such as natural gas, releases harmful pollutants into the air and water. Air pollution from fossil fuels includes toxic chemicals such as benzene, formaldehyde, sulfur dioxide, nitrogen oxides, particulate matter, carbon monoxide, and mercury. These pollutants have severe health impacts, with communities of color and low-income communities disproportionately affected. According to the World Health Organization (WHO), outdoor air pollution, largely driven by fossil fuel emissions, causes approximately 4.2 million premature deaths annually.
The extraction, refining, and transportation of fossil fuels also result in water pollution. Oil spills, a consequence of fossil fuel extraction and transportation, have devastating effects on aquatic ecosystems, killing marine life and causing long-term ecological damage. Additionally, fracking operations and wastewater disposal contaminate groundwater and drinking water sources with toxic substances like arsenic, lead, chlorine, and mercury.
Furthermore, the burning of fossil fuels contributes to global warming and climate change. The combustion of oil, coal, and gas releases greenhouse gases, driving the current global warming crisis. Methane, a potent greenhouse gas released during the extraction and transportation of natural gas, has an even higher global warming potential than carbon dioxide over a 20-year period.
To address these issues, a transition to clean energy sources and a reduction in the dependence on vehicles, electric or fossil-fuel driven, are necessary. This includes embracing renewable energy sources and decreasing the demand for cobalt in batteries, which is driven largely by the increasing production of electric vehicles.
