Automotive Thermoelectric Generator Market Trends:

Adoption of Waste Heat Recovery Systems

The automotive industry is currently focusing on incorporating generators that produce heat into exhaust systems to convert waste heat into electrical energy. This technique improves vehicle efficiency by powering onboard electronics while lowering reliance on traditional energy sources. In March 2024, the START project aimed to develop sustainable tellurium-free thermoelectric (TE) devices for waste heat recovery applications from secondary mineral resources (mining waste). This is increasing the automotive thermoelectric generator market growth.

Focus on Advancements in Thermoelectric Materials

Recent advancements in materials such as magnesium silicide and bismuth telluride have increased the efficiency and cost-effectiveness of generators for thermal electricity. These generators are ideal for large-scale automotive applications due to their ability to operate at higher temperatures and convert more energy. In September 2024, First Tellurium Corp. reported that its majority-owned subsidiary PyroDelta Energy had launched an initiative to produce thermoelectric generators for automobiles. The device is expected to replace alternators and increase efficiency for combustion engines while also helping electric vehicles generate more power.

Growth in Demand for Environmentally Friendly Thermoelectric Generators

The market is seeing a growth in demand for environmentally friendly materials such as magnesium silicide and bismuth telluride, which allow for efficient energy conversion from waste heat while minimizing environmental impact. This is consistent with the industry's emphasis on sustainability and reduced emissions. In January 2024, in research titled ‘Inverse-Perovskite Ba3BO as a High Performance Environmentally Benign Thermoelectric Material with Low Lattice Thermal Conductivity,’ published in Advanced Science, Tokyo Tech scientists reported on environmentally benign inverse-perovskites with high energy conversion efficiency and potential for practical application as thermoelectric materials.
