The use of coal in electricity generation has been a long-standing debate, with environmental impact being a significant concern for critics. Many organizations, including the UN Secretary General and the International Energy Agency, are calling for the phasing out of coal due to its polluting nature. However, developing countries still view coal as essential for economic development. The role of coal in transitioning to a sustainable future is a paradoxical topic of discussion.
Ramaco Resources, a U.S. firm, recently published an independent report on rare earth elements (REE) found at one of its mines in Wyoming. The report revealed a significant discovery of REEs, which are crucial for technological advancements. With China dominating the supply of rare earths, the U.S. and other countries are exploring alternative sources.
In a similar effort, West Virginia University received an $8 million grant to develop a method of extracting rare earth elements and minerals from coal waste. Penn State researchers are also working on ways to source rare earths from coal mines.
In the UK, efforts are being made to repurpose old coal mines for sustainable technologies. For example, Geothermal Engineering Limited announced plans to produce lithium as a by-product of its geothermal power generation projects.
Despite these developments, coal still accounts for over one-third of global electricity generation, according to the IEA. Nevertheless, discoveries like the one in Wyoming are a glimmer of hope for alternative sources of rare earth elements. When asked about the potential for more discoveries, Ramaco CEO Randall Atkins expressed cautious optimism.
