The Role of SiC in Enabling Renewable Energy and Grid Stability

 

The global silicon carbide (SiC) power semiconductors market was valued at US$ 1.8 billion in 2024 and is projected to expand at a robust compound annual growth rate (CAGR) of 19.0% over the forecast period from 2025 to 2035, reaching US$ 11.7 billion by the end of 2035. This remarkable growth is underpinned by the superior electrical and thermal properties of SiC-based devices, which enable high‐efficiency power conversion, compact form factors, and reliable operation under elevated temperatures and voltages. As industries pivot toward electrification, renewable energy integration, and high‐performance computing, SiC power semiconductors are poised to become foundational components in next‐generation power electronic architectures.

 

Market Drivers & Trends

1. Growing Demand for Electric Vehicles (EVs): The surge in global EV sales—from US$ 255.5 billion in 2023 to an estimated US$ 2,108.8 billion by 2033—is a primary catalyst for SiC device uptake. EV powertrains rely heavily on SiC MOSFETs and diodes in traction inverters, onboard chargers, and battery management systems. These components deliver higher power density, faster switching, and reduced thermal management requirements compared to conventional silicon technologies.
2. Need for Fast Charging Infrastructure: Rapid charging stations require compact, high‑power density converters that can handle high voltages and currents with minimal losses. SiC-based modules offer up to 30% efficiency improvements and significantly lower cooling system complexity, enabling smaller footprints and faster charge times for both public and residential charging units.
3. Shift Toward Renewable Energy: The integration of solar and wind power into the grid demands inverters capable of operating at high voltages and temperatures with minimal downtime. SiC inverters and power modules are emerging as the technology of choice for utility-scale and distributed renewable installations, driven by national decarbonization targets and favorable government incentives.
4. Industrial Electrification and Automation: Advanced motor drives, uninterruptible power supplies (UPS), and robotics systems benefit from the fast switching and compact design of SiC devices. This trend is accelerating in manufacturing sectors striving for higher throughput, lower energy costs, and reduced physical plant footprints.
