Hans-Ulrich Hartenstein

Member of the Board of Management of Conwico GmbH

Hans-Ulrich Hartenstein has been working in the energy industry for more than 30 years. He began his career in plant construction, where he went through all important domains of work such as process engineering, project management, sales and plant operation, and was ultimately in charge of them all. In addition to 15 years of experience in plant engineering, which he completed as Managing Director of the US subsidiary of a German plant manufacturer, when the German parent company went bankrupt shortly after the turn of the millennium, he built up several companies from scratch. Here too, his focus was always on environmental technology.

Hans-Ulrich Hartenstein has spent most of his professional life abroad as Managing Director of foreign subsidiaries of German companies. Most recently, for more than 10 years he was Managing Director of the US subsidiary of an engineering company belonging to a major German power company, which, however, in the USA provided plant construction services and other services in the field of environmental technology to American utilities.

Hans-Ulrich Hartenstein studied mechanical engineering at the Baden-Wuerttemberg Cooperative State University (DHBW) in Stuttgart and then studied process engineering at the University of Florida with a focus on environmental technology. During his professional career, he also earned an Executive MBA in Finance from the University of Toronto.
