A thermoelectric generator (TEG) is a machine that uses the Seebeck effect to convert heat energy directly into electrical energy. The Seebeck effect is a phenomenon where an electric voltage is produced by a temperature difference across a junction of two different kinds of materials.
The fundamental parts of a thermoelectric generator are as follows:
Materials with the Seebeck effect are known as thermoelectric materials. Typically, high thermoelectric efficiency semiconductor materials are used to make them. Lead telluride (PbTe) and bismuth telluride (Bi2Te3) are two materials that are frequently utilized.
Thermoelectric modules: These structures are made of several paired thermoelectric components linked in a series. The thermocouple name refers to each pair, which is electrically isolated from the other. The Seebeck effect causes a voltage to be created across thermocouples when a temperature differential is introduced.
Heat source: In order to produce a temperature gradient, the thermoelectric generator needs a heat source. This heat source can come from a variety of sources, such as body heat, combustion engine heat, geothermal heat, and waste heat from industrial processes.
Heat sink: A heat sink or a cooling system is attached to the thermoelectric generator’s opposing side. The device’s heat sink aids in preserving a lower temperature on that side, enabling the temperature difference required for the production of electricity.
The thermocouples generate an electric current when there is a temperature difference between the hot side and the cold side of the thermoelectric generator. It is possible to harness this current and utilize it to recharge batteries or power electrical equipment.
Thermoelectric generators have a number of benefits and drawbacks. Since they have no moving components and are solid-state, they are portable and dependable. They are not impacted by gravity or orientation and can function in a variety of environmental circumstances.
However, compared to conventional power-generating techniques, their efficiency is rather poor, making them more appropriate for low-power applications.
In fields including waste heat recovery, remote power generation, space exploration, and portable electronics, thermoelectric generators have found use. The efficiency and scope of thermoelectric generator applications in energy harvesting and sustainable power generation are being improved through ongoing research.
The Europe Thermoelectric Generator Market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Global Power Technologies (GPT), Inc., a pioneer in off-grid power solutions, announced the release of their new Sentinel Thermoelectric Generator, which is powered by natural gas. The Sentinel is a HAZLOC-approved, extremely low-maintenance power source for essential equipment that can deliver up to 8W DC of continuous power.
Sentinel from GPT offers an alternative solution for industrial equipment in metropolitan areas that is less expensive than a grid connection and more dependable than solar and batteries. The Sentinel’s reliability is based on a Catalytic Heater Cartridge that is simple to service and thermoelectric performance that has been improved to address reliability difficulties with competing sources. The Sentinel is small enough to be installed by one person, fits into existing locations, and can be mounted on a wall or a fence post.
