The Horizon 2020 EU-funded REFLECT project is organising a geothermal stakeholder workshop on 21 June 2022 in İzmir, Turkey. During this physical event, the most relevant project results for geothermal operators will be presented. Online participation won’t be possible.

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. Scaling and corrosion are the cause of downtime, maintenance costs and even failures in geothermal installations. REFLECT aims to prevent these problems related to fluid chemistry rather than treat them. Because physical and chemical fluid properties are often poorly defined, large uncertainties in current model predictions prevail. REFLECT has been collecting new, high-quality data in critical areas to tackle these uncertainties. The existing and new data collected will be implemented in a European Geothermal Fluid Atlas and in predictive models. These and other relevant results for improving the efficiency of geothermal operations will be shared with the workshop participants.

Please register for the workshop at the following link:

The REFLECT stakeholder workshop brings together actors from the scientific community with geothermal operators. The workshop will serve two purposes: First, we will showcase results from the REFLECT project and explain the application of those results to geothermal operations. Second, we will learn from operators about the challenges they encounter during operation and how they mitigate those challenges. We will exchange solutions and mitigation approaches, but also define the need for further research and development.

The workshop will focus on:

  • Geochemical challenges related to high-temperature geothermal fluids with examples from Turkey and Iceland
  • Geochemical challenges of saline and low temperature geothermal operation with examples from Germany and the Netherlands
  • Results from REFLECT’s investigations on scaling, degassing and the influence of microbial activity on geothermal operations
  • Tools for prediction of geothermal challenges and improving plant operations: the high-temperature geothermal fluid sampler developed in REFLECT, the Fluid Atlas and software tools for predictive modelling

Participation of geothermal operators, consultants, investors, project developers, or  technology developers is highly encouraged.
