The REFLECT project is organising the webinar ‘Efficiency in geothermal operations and virtual visit to Insheim‘ on 4 November 2021, 15:00 – 16:30 CEST (Brussels time).

The efficiency of geothermal utilisation depends on the behaviour of fluids that transfer heat between the geosphere and the engineered components of a power plant. REFLECT aims to prevent problems related to fluid chemistry rather than treat them. The webinar will present the first results of the project’s research for improving the efficiency of geothermal operations. In addition, participants will have the opportunity to take a virtual tour of the geothermal power plant in Insheim, Germany (Pfalzwerke Geofuture GmbH). The tour will provide an overview of the functioning of the plant and the current operational problems. 

The host of the webinar will be REFLECT project manager Katrin Kieling. Project partner Joerg Uhde (Pfalzwerke Geofuture GmbH) and, REFLECT scientific coordinator Simona Regenspurg (Helmholtz Zentrum Potsdam Deutsches GeoForschungsZentrum) will be the speakers.

  • Dr Simona Regenspurg has been working as a research associate at Helmholtz Centre Potsdam German Research Centre for Geosciences in the Section Geoenergy since 2009. She is head of the working group “Geothermal Fluids”. The focus of her research is on the study of geochemical processes that take place during the operation of geothermal plants. These include reactions under increased pressure and temperature conditions, interactions between water and rock and their effects on the environment. Simona studied geology/hydrogeology at Ludwig-Maximilians-Universität in Munich, Germany, and completed research stays in the USA (Colorado School of Mines, Golden), Sweden (Royal University of Technology (KTH), Stockholm) and Switzerland (Ecole Polytechnique Fédérale de Lausanne, EPFL). She habilitated and teaches at the Free University of Berlin.
  • Joerg Uhde, CEO of Pfalzwerke geofuture Ltd, the owner and operator of the Insheim geothermal power plant in SW Germany. He holds a master degree in mining engineering. Joerg has a wide background in geothermal projects in Germany and Switzerland. He was head of Axpo Power AG’s Geothermal Power Plants Department. Axpo is the dominant energy provider in Switzerland. With his expertise in mining and drilling technology, he enabled the company to push ahead with geothermal projects in Switzerland and abroad and thus from a geothermal point of view face the demands of the future energy generation. Prior to his assignment with Axpo Power AG he got predominantly involved in the field of geothermal probe drilling and the development of deep drilling technologies. At his present position he focuses on optimising the thermal water circuit by solving severe scaling and corrosion effects. In doing so he helped to set up several European and national R&D consortia.
