Thermoelectric generator market growth accelerates with EU smart-building TEG mandates and rising adoption of micro-TEGs for maintenance-free industrial IOT nodes.
Hyderabad, India, Nov. 18, 2025 (GLOBE NEWSWIRE) — According to the latest insights from Mordor Intelligence, the thermoelectric generator market size is projected to grow from USD 1.05 billion in 2025 to USD 1.68 billion by 2030, at a CAGR of 9.93%. The thermoelectric generator industry growth is driven by stricter emission regulations, technological advances boosting conversion efficiency to 15%, and broader applications ranging from automotive waste-heat recovery to wearable devices. Automotive remains the largest revenue contributor, while low-power, maintenance-free harvesters are expanding consumer adoption.
Regulatory support, such as the U.S. EPA’s 2024 greenhouse-gas standards, favors solid-state solutions. Material innovations in nano-structured bismuth-telluride and silicon-germanium alloys are reducing payback times and increasing competitiveness.
Emerging Trends
Rising Use in Remote and Deep-Sea Operations
Extreme missions, from space exploration to underwater research, are driving strong interest in advanced thermoelectric generators. Recent technological improvements have enhanced efficiency in high-temperature applications, enabling long-duration operations without relying on heavy batteries. In subsea environments, autonomous systems harness natural thermal gradients to sustain significant power loads over extended periods.
Harnessing Waste Heat in Data Centers
With the rise of high-performance computing, managing heat has become essential. Advanced cooling systems now allow thermoelectric devices to capture energy that would otherwise be lost, improving overall efficiency. Modular designs are increasingly integrated into liquid-cooling loops, helping facilities reduce energy waste while creating opportunities to repurpose excess heat.
