The annual market for sub-watt thermoelectric generators (TEGs) is expected to grow at a compound annual growth rate of more than 110% over the period 2014 to 2020, according to market research firm Infinergia LLC (Grenoble, France).

In other words the market for these low power TEGs will, on average, more than double each year from about 100,000 units shipped in 2014 to about 9 million shipped in 2020. Infinergia is a market research and consultancy firm that focuses on clean energy and electronics.

Infinergia does not provide an estimated market size by value for the low power units but the total annual market for TEGs is set to move from $26 million in 2014 to $77 million in 2020, the firm said, a CAGR of about 20 percent.

TEGs are moving into second and third generation technologies which are opening up new opportunities, according to Infinergia. Products using sub-watt thermal energy harvesting are being commercialized in several applications across two main segments: infrastructure and buildings and industrial and professional, the firm said.
