Johannes Eckstein - Fraunhofer ISI

Wissenschaftlicher Mitarbeiter

Dr. Johannes Eckstein ist seit 2019 wissenschaftlicher Mitarbeiter und Projektleiter im Geschäftsfeld Klimapolitik der Abteilung Energiepolitik und Energiemärkte. Hier arbeitet er an der Schnittstelle zwischen Klimapolitik und Industrie, insbesondere zu innovativen Förderinstrumenten wie dem EU-Innovationsfonds oder den Klimaschutzverträgen. Einen weiteren Arbeitsschwerpunkt bildet die Energiesystemmodellierung und damit verbundene Politikfragestellungen, z. B. nach der Relevanz von Wasserstoff für die Dekarbonisierung. Neben Studien über die EU stehen hierbei unter anderem die Länder des westlichen Balkans und in Südostasien im Fokus. Er leitet und arbeitet in Projekten mit Bezug zum internationalen, EU oder nationalen Kontext.

Johannes Eckstein studierte Meteorologie am Karlsruher Institut für Technologie mit einem Austauschjahr an der Istanbul Technical University. Er war wissenschaftlicher Mitarbeiter am Karlsruher Institut für Technologie, mit einem Arbeitsschwerpunkt in der Klimamodellierung. Seine Dissertation schloss er 2017 ebendort zur Modellierung atmosphärischer Spurenstoffe und Wasserisotope ab.
