New technology for CO2 reduction
Half-Heusler waste heat conversion reduces CO2 emissions of cars
(firmenpresse) - In the energy debate about CO2 reduction, Hesseor example, to save up to 4% CO2 emissions when used in a car.
Together with several partner companies, Isabellenhmonstrate the complete production process for material batches of 10 kg with its production line.
Annual production volume of 25 tons of half-Heusler material possible
A 150 m2 production hall was built for this purpose at the company headquarters in Dillenburg, Hesse. Overall, a total of six scientists and technician are currently working on this topic at Isabellenhuction run is possible with the system. This corresponds to an annual production of 25 tons.
Thermoelectric waste heat conversion is nearly ready for market
Thermoelectric waste heat conversion based on half-Heuslers is almost ready for market. The technology was and is already tested and tried in the exhaust gas systems of cars and trucks under realistic everyday conditions. With 60 to 70 grams of half-Heusler material, a vehicle with a thermoelectric generator (TEG) installed achieves an efficiency of up to 5% from the waste heat. This energy is converted into electricity and fed into the on-board electrical system. The effect: The fuel consumption is reduced and the CO2 emissions are reduced per vehicle by up to 4%.
Relevant for environmental policy and competitive
The relevance of this technology is obvious. Automotive manufacturers will face strict environmental requirements in the future. This is why every gram of CO2 saved matters. The half-Heusler waste heat conversion is also competitive from an economic point of view. The production process realized as part of the EU project generally makes it possible to achieve the market-demanded cost target of EUR 0.50/watt under mass production conditions. A half-Heusler-based thermoelectric generator that, for example, generates 400 watts of electrical energy, would cost about EUR 200.
A good mix of properties allows for use in high-temperature applications
Due to their good material properties, half-Heusler materials are suitable for high-temperature applications, such as combustion engines. They generate exhaust gas temperatures between 400 and 600ms.

Unternehmensinformation / Kurzprofil:
Isabellenhütte arose from a copper smelter, which was first documented in 1482 and was renamed as “Isabelle Kupferhütte” in 1728. Since 1827, Hesse’s oldest company has been run as a family-owned and operated business, now in its eighth generation.
In 1901, Dr. Fritz Heusler discovered the Heusler alloys. They consist of non-magnetic individual components. However, when the elements are combined in Heusler compounds, they have strong ferromagnetic properties.
Heusler compounds are the historic predecessors of the material class discovered by scientists about 15 years ago, the so-called half-Heusler compounds. They are characterized by a flexible grid structure that can be filled with different metals. The effect: This results in countless material combinations with different physical properties. The half-Heusler production of thermoelectric generators also benefits from this, which Isabellenhütte uses for the waste heat conversion in high-temperature applications, such as combustion engines.
With around 950 employees, the company operates internationally in the three business divisions of precision measurement technology, precision and power resistors and precision alloys. It is one of the most important international manufacturers of electrical resistance materials and thermoelectric materials for temperature measurement as well as of passive components.
