Zinc’s Evolving Role in Energy, Health, and Sustainability

Zinc Use Cases

While lithium, cobalt, and copper often dominate discussions about future-critical resources, zinc plays an equally vital, though often overlooked, role. Historically viewed as a standard base metal, its utility has evolved significantly. Zinc has moved beyond its traditional industrial roots to become a key component in human health, food security, and green energy technologies. This versatility makes it an essential element in the transition toward a decarbonized future.

Powering and Protecting Green Energy

It is easy to forget that renewable energy requires massive physical infrastructure. Solar and wind power are highly steel-intensive, which introduces a significant problem: rust. Without mitigation, corrosion can severely shorten the lifespan of the energy grid.

Zinc provides the literal armor for this transition. Through galvanization (hot-dip zinc coatings or thermal spray), it shields renewable infrastructure from the elements, ensuring a solar park or wind farm can last for decades. For perspective, offshore wind turbines typically require around 0.4 tonnes of zinc per megawatt of capacity (e.g., 4 tonnes for a 10 MW turbine) to maintain structural integrity against the harsh marine environment, with higher amounts possible for thicker coatings or larger foundations in aggressive conditions

But the real shift is happening in energy storage. As the world looks for safer alternatives to lithium for the power grid, zinc-based batteries are emerging as a primary contender. Because they utilize water-based electrolytes, they are inherently non-flammable—a "killer advantage" for large-scale energy storage in urban environments. Moreover, with zinc being approximately 3 to 4 times more abundant in the Earth's crust than lithium, it offers a more stable and cost-effective supply chain for the long-term energy transition.

From Soil to Soul: A Micronutrient Powerhouse

Zinc’s versatility extends far beyond the industrial. It is one of the few elements that is as critical to a computer chip as it is to a human lung.

Currently, up to 50% of global cereal soils are estimated to be zinc-deficient, a "hidden hunger" that limits crop yields and reduces the nutritional value of our food. When soils lack zinc, the crops grown there lack the nutrients required for a healthy human immune system.

By integrating zinc into fertilizers, we aren't just increasing crop tonnage; we are "biofortifying" our food supply. This is a frontline defense combating malnutrition for the estimated 17% of the global population at risk of zinc deficiency, which is essential for over 300 enzymatic reactions in the human body.

Why the Future is Zinc-Heavy

As we look toward 2030, the demand for zinc is projected to rise, driven by three major shifts:

• High-Tech Hardware: In the electronics sector, zinc-based compounds (e.g., zinc oxide (ZnO) or cadmium zinc telluride (CZT)) are key materials in semiconductors and high-performance sensors, enabling applications from medical imaging (e.g., precise radiation detection in CT/SPECT systems) to emerging high-frequency technologies (e.g., sensors in flexible electronics or optoelectronics for network devices).

• The Circular Economy: Zinc is 100% recyclable without any loss in quality. In fact, its established recycling infrastructure makes it a cornerstone of sustainable resource management, with secondary production growing steadily to meet rising demand International Zinc Association - Sustainability.

• Health & Pharmaceuticals: Beyond basic supplements, zinc is essential for insulin stabilization and advanced wound healing, ensuring its place in the future of medical science.

A Critical Link in the Chain

Zinc is unique because it doesn't just do one thing well; it does everything. It protects our infrastructure, powers our electronics, stabilizes our climate, and nourishes our bodies. As we move deeper into an era defined by resource efficiency and sustainability, our reliance on this versatile element will only grow.

In the race to build a more resilient world, zinc isn't just a participant—it’s the foundation.
