Research topics
Valentin Goldberg at the reception hosted by Chancellor Scholz in Santiago de Chile, January 2023.

With our research on the material use of thermal waters, we accompany the development of this forward-looking approach from the scientific side. We identify fundamental challenges and opportunities and develop solutions together with our partners in order to further develop the technology. We make our results available to the general public in the form of a wide variety of publications and are thus the central point of contact on the subject for local residents, journalists, industry and politics.
