Automotive Thermoelectric Generator Market

An Automotive Thermoelectric Generator (ATEG) is a technology that transforms heat energy, typically lost through a vehicle's exhaust system, into usable electrical energy using the Seebeck Effect. These devices are designed to enhance vehicle efficiency by converting waste heat into electricity, which can then power vehicle electronics or recharge the battery. This reduces the load on the alternator and contributes to better fuel economy and lower emissions. ATEGs are particularly valuable in internal combustion engine (ICE) vehicles and are increasingly being integrated into hybrid systems to boost energy efficiency.

Market Size

The global Automotive Thermoelectric Generator market was valued at approximately US$ 178.4 million in 2024, with projections suggesting it will reach US$ 412.6 million by 2030, growing at a Compound Annual Growth Rate (CAGR) of 15.0% during the forecast period from 2024 to 2030.

The United States market is set to follow a similar trend, valued at US$ 56.7 million in 2024 and forecasted to climb to US$ 127.3 million by 2030, with a CAGR of 14.4%.

In 2023, global sales volumes hit 250,000 units, with passenger vehicles comprising 80% of total market value. However, the commercial vehicle segment is outpacing all others in terms of growth, expanding at an annual rate of 18%. A significant 30% increase in R&D investment was observed in 2023, with a focus on developing high-efficiency thermoelectric materials.

Material-wise, Bismuth telluride leads the market with a 75% share, while skutterudite-based systems are gaining traction due to their ability to handle higher temperatures, growing at 22% CAGR.
