The world’s population continues to grow rapidly, driving energy needs to unprecedented levels. In an effort to meet this demand while minimizing carbon emissions, many nations are increasingly relying on renewable energy sources. These technologies, however, depend on essential raw materials. One state has recently identified a vast deposit—around 4 million tonnes—that could be extracted over nearly three decades. While this discovery holds promise for the nation’s energy future, large-scale projects of this kind often face both obstacles and criticism.
Renewable energy technologies require crucial elements
Renewable energy sources are popular alternatives to burning fossil fuels for power as they have little to no emissions, can be more economical due to lower operational expenses, and are naturally replenished. However, nothing in life is perfect. These renewable sources face challenges such as intermittency and storage limitations. The renewable technologies that have been designed to address these challenges are also face challenges.
One such a challenge, is that they require certain components made from particular elements. In the United States, these elements are not necessarily scarce, but the country primarily depends on imports due to domestic processing limitations and recover capability limitations, according to the Innovation News Network. Thankfully, the U.S. has been expandings its endeavours to boost domestic production.
A colossal find that can be mined over nearly 30 years
In Southern Arizona, within the historic mining district of the Patagonia Mountains, a company called South32 plans on changing the U.S. future with a colossal reserve. The project, officially known as the Hermose project, has a reserve of two particular elements that has the potential to power the U.S.’s energy future, both is domestic supply and production.
The Hermosa project is the only advanced project of its kind in the U.S. that will potentially produce two federally assigned critical minerals, manganese and zinc. Hermosa also includes reserves of copper, silver and lead. These critical minerals are crucuial to exploit everything from renewables to lithium-ion batteries, and pipes and plumbing components.
Trump wants to blow up the ocean, but now he may not have to. According to South32, the mine has an estimated life of 30 years, with a reserve of 4 million tonnes of ore to mine during its operation life. South32 has the following goals for its Hermosa project:
- Improve critical mineral domestic suppy
- Boost local economy
- Enhance Santa Cruz County and locl community livelihood
- Set a new standard for sustainable mining
Setting a new standard for sustainable mining
According to Axios, this is how South32 plans on running a net-zero mining operation:
- Using battery electric equipment fleets underground
- A mine design to keep disturbance minimal
- Only use 750 acres throughout mine’s life
- Sourcing and training 80% of workforce from local community
- Using 90% less water than other operations in surrounding region
Criticism is unavoidable
According to AZ Luminaria, since operations have begin, water samples have indicated increased levels of iron, lead, zinc, sulfate, and manganese. The treated water is being discharged into the Harshaw Creek. A local hydroogist, Chris Gardner, has raised concerns of the Hermosa project’s negative impact on the region’s water resources. The discharged water has more than the waterway usually carries, resulting in the contaminating substances to naturally dissolve from the stream and leach into the groundwater.
This colossal find will significantly boost the U.S.’s dometic supply of critical minerals, assisting the nation’s transition to renewables, boosting its national security, and supporting local high-tech industries. Overall, the massive reserve will be highly advantageous to the country, but as with all mining projects, careful management and appropriate environmental regulations are vital to ensure not only the well-being of the surrounding environment, but the surrounding local communities as well.
