From Black Gold to Green Energy 24

From Black Gold to Green Energy

It may appear contradictory to switch from black gold to green energy, which is another term for crude oil, considering that the latter is linked to pollution and non-renewability. On the other hand, there is unrealized potential for the oil industry to play a major role in the green energy revolution. Leveraging the infrastructure and resources of the oil industry can help to allow a more seamless transition to sustainable energy as the globe struggles with climate change and the pressing need to decrease carbon emissions.

 From Black Gold to Green Energy

Traditionally the foundation of the world’s energy supply, crude oil is essential to many economies. However, the globe is warming as a result of its extraction and consumption.

Important tactics include using carbon capture and storage (CCS) to cut emissions, converting oil rigs into offshore wind farms, and making significant investments in the development of renewable energy research and technology.

The oil sector can significantly contribute to the development of a sustainable future by refocusing its enormous financial and technological resources on green energy. This strategy not only takes care of environmental issues but also makes sure the industry stays relevant in a time when renewable energy sources are taking over.

A few minerals, referred to as key minerals, are vital to the current worldwide shift away from fossil fuels and toward renewable energy sources. In order to manufacture cutting-edge technology like solar panels, electric cars, and wind turbines, certain minerals, particularly rare earth elements (REEs), are necessary. Interestingly, new studies have shown that these vital REEs are frequently discovered near coal resources, which have historically been mined for fossil fuels.

Research Findings on REEs in Coal Deposits

The Uinta coal belt, which crosses portions of Colorado and Utah, has been the subject of a thorough investigation by University of Utah researchers. The possibility of REE reserves in this area, which was formerly well-known for its massive coal mining activities, is drawing interest. This coal belt contains both operating and closed mines that have high quantities of rare earth elements (REEs). The study was published in a peer-reviewed journal.

Important Rare Earth Elements Subset

The 17 chemically related elements that make up the rare earth elements are essential to high-tech companies.

Owing to their strong demand, the following subset of REEs is of special interest:

Electric vehicle motors and wind turbines employ neodymium (Nd) in their strong magnets. For electric car motors and wind turbines, dysprosium (Dy) is essential because it strengthens magnets under high-temperature conditions.

Trebium (Tb), Yttrium (Y), and Euphoria (Eu): Phosphorus is necessary for lighting and display technology.

Increased Densities in the Uinta Coal Region

The concentration of REEs in coal and adjacent strata was examined by the study team using sophisticated geochemical techniques. Their research revealed that:

Concentration Levels: The concentration levels of rare earth elements (REEs) in these coal deposits were considerably greater than the mean crustal abundance, indicating that these locations may be feasible and profitable sources of REE extraction.

The study revealed that the distribution patterns of rare earth elements (REEs) in coal seams and related geological layers were not uniform. This suggests that certain zones within the coal deposits are notably abundant in these elements.

Extraction Potential:
The study demonstrated the viability of recovering rare earth elements (REEs) as a coal mining byproduct, possibly turning waste into priceless resources.

Consequences for the Energy Transition

For the energy transition, the finding of REEs in coal seams offers a counterintuitive yet exciting opportunity:

Benefits to the Economy: The recovery of rare earth elements (REEs) from coal reserves may help areas that have historically relied on coal mining make the transition to a more diverse and long-term economic basis.

Environmental Concerns:
Although mining coal has a large negative influence on the environment, the extraction of rare earth elements (REEs) from active or closed mines may be able to lessen these effects by leveraging the infrastructure already in place and avoiding the need for new mining operations.

Supply Chain Security: Since a tiny number of nations, most notably China, presently control the majority of the world’s supply of rare earth elements (REEs), the establishment of local sources in the Uinta coal belt might improve supply chain security for the US and lessen reliance on foreign sources.

Investigating Other Rare Earth Sources

Because rare earth elements (REEs) are crucial to modern technologies, the shift to renewable energy sources strongly depends on these minerals. The Utah Geological Survey, the Colorado Geological Survey, and the University of Utah recently collaborated on research that sheds light on a novel strategy for locating these essential elements.

Carbon Ore, Rare Earth and Critical Minerals (CORE-CM), a Department of Energy project, is the sponsor of this study. A $9.4 million grant request for additional federal funding to continue this significant effort has been made possible by the preliminary findings.

The CORE-CM Initiative

Investigating coal and coal byproducts as substitute sources of rare earth elements and other essential minerals is the goal of the CORE-CM project. The larger objective of guaranteeing a steady and domestic supply of these materials—which are crucial for the energy transition and national security—is in line with this endeavor.

Important Research Findings

High amounts of rare earth elements have been found in the Uinta coal region, which crosses parts of both states, according to research conducted by the University of Utah and the geological surveys of Colorado and Utah. The following are the study’s key findings:

High Concentration of REEs: Rare earth elements are present in the coal seams of the Uinta belt at considerably higher concentrations than are generally found in the crust of the earth. This implies the possibility of an economically feasible extraction of REEs from these sources.

Strategic Distribution: The Rare Earth Elements (REEs) exhibit a non-uniform distribution, with a concentration in particular zones found within coal seams and neighboring geological layers. To focus extraction efforts and increase yield, this zonal distribution is essential.

Possibility of Dual Resource Utilization: It might be able to convert coal mining waste into useful resources by removing rare earth elements (REEs) from coal and coal byproducts, supporting both environmental and economic objectives.

Consequences for the Energy Transition and Economic Growth

There are numerous significant ramifications from the finding of REEs in the Uinta coal area.

Economic Revitalization: The growth of REE extraction enterprises may provide a stimulus to previously coal-mining-dependent regions, assisting in the shift of these areas toward more sustainable forms of employment.
Environmental Benefits: Some of the environmental effects of extracting REEs can be lessened by using the infrastructure already in place for coal mining. This strategy may lessen the environmental impact because it makes use of already-existing disruptions rather than starting new mining operations.

Enhanced Supply Chain Security: As China now controls the majority of the world’s REE market, expanding domestic REE sources is essential to lowering dependency on foreign suppliers. By doing this, supply chains for vital technology are kept stable, and national security is strengthened.

Next Steps and Challenges

The CORE-CM project team is looking for extra funds to continue their research because of the initial positive results. The federal assistance of $9.4 million that has been proposed would help:

Technological Advancements: Creating and improving extraction methods to economically and effectively recover rare earth elements (REEs) from coal and byproducts.

Environmental Assessments: To guarantee sustainable extraction methods, comprehensive environmental impact evaluations are carried out.
Policy Support: Working with legislators to establish policies that will encourage development and investment in the rare earth industry.


Finding sustainable sources of rare earth elements is made possible in large part by the cooperative study led by the University of Utah and funded by the Utah and Colorado geological surveys as part of the CORE-CM project. A prospective path for resource extraction that may be essential to the global energy transition is made possible by the high concentrations of rare earth elements (REEs) found in the Uinta coal region.

In order to overcome the technological and environmental obstacles and ultimately contribute to a more robust and sustainable energy future, more financing will be needed as this research advances.

Which natural resource is called black gold?

Due to its restricted availability and lengthy formation period (many millions of years), petroleum—also referred to as “black gold”—is a very valuable crude oil that is produced from the Earth’s crust and has a wide range of industrial uses.

What liquid is also called black gold?

Due to the black color of crude oil that is recovered from the ground, petroleum is sometimes referred to as “Black Gold.” Its oils and worth have led some to refer to it as gold. It is quite challenging to locate.

Is green energy always clean?

Although not all renewable energy sources are clean, all clean energy sources are by definition “clean.” It may be renewable to burn wood from forests that are managed sustainably, but doing so emits carbon dioxide into the atmosphere, making it unclean.
