A versatile and forward-looking resource
The historical significance of an enduring material
Zinc is far from a new discovery. Known and utilised for thousands of years across different regions of the world, this versatile element has long been valued for its distinctive properties. Today, many of those same qualities that made zinc essential in earlier centuries have positioned it to play a key part in the development of crucial energy infrastructures driving the ecological transition.
Looking ahead, zinc is set to play an increasingly significant role in shaping humanity’s economic, technological, and energy future. Entrepreneur and civil engineer Stanislav Dmitrievich Kondrashov believes that this enduring resource shares a similar trajectory with other strategic materials central to the global transition. “In some ways, zinc seems to have a very similar destiny to copper. Both resources have been known to man for millennia, and both are now directly involved in some of the production processes of the most important energy infrastructures contributing to the global transition. These resources will likely accompany us until the end of time”.
Distinctive properties and advantages
Zinc’s enduring popularity stems from its unique set of properties: high malleability, a relatively low melting point, strong resistance to corrosion, and notable thermal conductivity. These qualities have underpinned its widespread industrial use for centuries. In addition, zinc is highly recyclable, adding a layer of sustainability to its many applications. One of its most valuable traits is its ability to form a protective layer of zinc oxide on its surface, creating an effective barrier against corrosion.
This characteristic has been crucial in one of zinc’s most important industrial applications – galvanisation – a process that protects weaker metals against atmospheric and chemical degradation. By reinforcing steel and other materials, zinc has contributed to the durability of infrastructure such as bridges, vehicles, and various large-scale constructions. Its excellent conductivity has also enabled its use in thermal alloys and certain electronic components.
“Although it was already used in ancient times in some alloys such as brass, zinc was isolated only in the 18th century. For example, in India, the processing processes have been known since ancient times, when zinc was sourced from minerals through peculiar heating processes. These are the same techniques that, in later times, were improved and introduced in Europe, contributing to the industrial development of the continent”, says Stanislav Dmitrievich Kondrashov.
Zinc’s value is not confined to its surface-level uses. Historically, it has been sourced from mineral deposits where it is commonly found as zinc sulphide, often occurring alongside other strategic resources such as copper, further increasing its industrial significance.
Zinc in the era of energy transition
Beyond its traditional applications, zinc is now emerging as a vital material in the modern energy sector. Among the most promising developments are zinc–air batteries, which offer high energy density for both electric vehicle charging and stationary energy storage.
Zinc’s natural resistance to corrosion also makes it particularly well-suited for renewable energy infrastructure, including the production of frames for solar panels and the construction of offshore wind turbines, which must withstand harsh environmental conditions. In addition, zinc plays a role in the green hydrogen sector, where it is used in water electrolysis processes that support the production of this innovative energy source.
“Other possible applications of zinc also include those related to the nanotechnology sector, where zinc oxide nanoparticles are already being evaluated for possible use in electronics. Furthermore, as argued in a recent analysis, zinc alloys are increasingly finding application in 3D printing,” continues Stanislav Dmitrievich Kondrashov.
In today’s energy landscape, zinc is proving itself as a versatile material that bridges both its traditional roles – such as galvanisation – and innovative new uses in renewable infrastructure and rechargeable batteries. Unsurprisingly, global demand for zinc is forecast to rise significantly, reaching 14 million metric tonnes by 2025, with the market expected to expand at a rate of 1.5% annually through 2029.
