Thermal energy harvesting is the process of converting a temperature difference into electrical energy using thermoelectric generators (TEGs).
This effect relies on properties of a special class of semiconductors known as thermoelectric materials. When thermal energy migrates through them from a hotter side to a colder side, they create an electric potential.
To operate, our products require a heat flow. Typically, this will be taken from a hot surface such as a hot water pipe, sent through the device and returned to the cold side, usually the surrounding air via a cooling fin or a cold-water return pipe. The amount of energy the product produces is dependent on both the maximum hot temperature and the temperature difference. A higher temperature will produce more energy.
Thermoelectric devices have the advantage of being compact, lightweight, solid state with no moving parts, silent in operation and do not require maintenance.
Integrating TEGs with smart ultra-low power management results in a constant battery-like power supply with “infinite” lifetime as long as a temperature difference is available.
In cooperation with Aarhus University, we have developed two new ground-breaking energy materials for energy optimization. The new materials are based on Zinc Antimonide and Magnesium Silicide and are capable of transforming a temperature difference to electricity at higher temperatures than before.
Thermal energy is the most reliable and most power-dense energy source for being harvested in an industrial context. Besides offering the possibility to supply sensors not suitable for battery solutions, it is also sustainable and underlines the industry’s effort towards being CO2 neutral.
TEGnology combines advanced thermal energy harvesting with state-of-the-art power management, providing a reliable, cost-efficient, maintenance free “internal” power supply for IIoT devices based on thermal energy harvesting from available process heat.
