Advanced Materials

Hyundai Motor Group is dedicated to lead the future through its analysis on the innovative trends of the future
and advanced materials technology.

High-efficiency Energy Conversion Materials,
Aiming for Maximum Efficiency

Many problems confront us – the approaching depletion of fossil fuels, rises in oil prices, and a myriad of other energy issues we need to address.
Hyundai Motor Group has been trying to develop new energy sources that can solve these problems once and for all.
Of these, we are developing a solar energy system that uses solar power and an electro-thermal conversion system,
which can both maximize our energy efficiency.

Thermoelectric Conversion System, Maximizing energy efficiency

Thermoelectric conversion is a process in which thermal energy is directly converted into electric energy for thermoelectric power generation, or the other way around for thermoelectric cooling/heating.

Thermoelectric power generation is based on the principle in which thermal energy is transferred from a hot place to a colder place while accompanying negative electrons and positive holes of semiconductors, thus generating electric power.
The principle is used to convert the waste heat from the exhaust gas of combustion engine into electricity, resulting in reduced mechanical load of the alternator and less fuel consumption.
This, in turn, leads to a higher mileage and less CO₂ gas emission of vehicles.

Thermoelectric cooling/heating is an environmentally friendly technology in which electric current produces temperature gradient, so that one side is heated up while the other is cooled down.
The technology provides cooling and heating at the same time without any refrigerant and noise, being applied to the auxiliary air-conditioning for cabin comfort as well as the controlling temperature of automotive parts.
