Green Energy Transformation Sparked by Silicon Carbide Technology
In the realm of technology, a lesser-known but increasingly important silicon-based material is taking centre stage: Silicon Carbide (SiC). This hard, versatile substance is poised to revolutionise power electronics and energy-efficient solutions worldwide.
Currently, the SiC market is valued between approximately $3.5 billion and $4.82 billion in 2025, according to various sources, with expectations of strong growth driven primarily by electric vehicles (EVs), renewable energy, industrial automation, and high-efficiency power electronics [1][5]. Key industries fueling demand include automotive (especially EVs and charging infrastructure), renewable energy systems, data centres, aerospace, and industrial motor drives [1][5].
The future growth potential of the SiC market is significant and robust. Projected to reach $7.2 billion by 2035 with a CAGR of 7.5% over the decade from 2025 to 2035 [1], another source forecasts reaching nearly $8 billion by 2030 at a CAGR of approximately 10.6% from 2025 [5]. The SiC wafer segment specifically is forecasted to grow even faster, expected to hit about $8.29 billion by 2032 with an aggressive CAGR of 20.3% between 2025-2032 [3][4].
This rapid expansion is propelled by several factors. SiC's superior thermal conductivity, high breakdown voltage, and lower switching losses compared to traditional silicon semiconductors and gallium nitride (GaN) make it ideal for power electronics operating above 650V [1][5]. Increased investments and government subsidies, such as the U.S. CHIPS Act, European Chips Act, and Japan’s METI subsidies, are driving expansion of domestic wafer fabs and supply chains, reducing reliance on Asia-Pacific manufacturing hubs [5]. Scaling to larger wafer sizes (6-inch, 8-inch) is improving production yields and reducing costs, making SiC more competitive and accessible [1]. Emerging applications, including AI data centres, represent new growth avenues alongside EVs and renewable energy [2].
SiC's advantages extend beyond power electronics. Its 10x higher electric field capacity than silicon makes it suitable for handling large power loads, a factor that is increasingly important in data centres, where increasingly powerful chips and power demand from AI require stronger power supply and control electronics than silicon can provide. SiC is also growing in importance in robotics, allowing for the motor drive to be smaller and located directly in the articulations.
A prime example of the growing importance of SiC can be seen in the semiconductor industry. Aehr Test Systems, a company specialising in silicon carbide, produces equipment for testing the SiC wafers. Their customer base includes TSMC, Texas Instruments, Seagate, Nvidia, Cisco, Qualcomm, and Bosch, demonstrating the widespread adoption of SiC in the semiconductor industry.
In summary, the silicon carbide market is currently robust and growing rapidly, with multiple credible forecasts indicating double-digit CAGR growth, particularly in the wafer segment and power device market over the next decade. The technology’s advantages and strong end-market demand position it as a strategic material for future power electronics and energy-efficient solutions worldwide.
