In 2025, renewable electricity generation surpassed coal for the first time, accounting for 34.3% of the global power mix. While wind, solar, and new-type energy storage continued to expand rapidly as key drivers of future power systems.
This transformation is placing higher demands on electrical equipment. Devices used in wind-solar-storage projects, energy storage stations, and transmission networks must withstand more frequent switching, higher current interruption requirements, and long-term exposure to complex outdoor environments.
Electrical contact materials play a central role in current conduction and circuit protection. As
renewable energy systems become larger, more complex, and more demanding, contact materials must deliver higher reliability, longer service life, and more stable performance.
Material Challenges in Renewable Energy Applications
Renewable energy systems often operate under complex and demanding conditions.
First, the intermittent output of solar and wind power requires switching devices such as contactors, relays, and circuit breakers to operate more frequently. This increases arc erosion on contact surfaces, leading to material loss, unstable contact resistance, and shorter service life.
Second, large-scale energy storage systems and high-capacity power distribution networks are often exposed to higher inrush currents and short-circuit stress. This places greater demands on current-carrying capacity, temperature-rise control, and anti-welding performance, increasing the risk of excessive heating or device failure.
Third, outdoor renewable energy applications may face harsh environmental conditions. Salt spray in offshore wind farms, strong UV exposure in high-altitude PV projects, and large temperature differences in desert power stations can accelerate oxidation, corrosion, and long-term material degradation.
These challenges can increase lifecycle maintenance costs and affect power system safety and stability. High-performance electrical contact materials are therefore essential for improving equipment reliability, extending service life, and supporting more efficient renewable energy applications.
