After a welcome by Peter Szucs, dean of Faculty of Earth Science & Engineering, University of Miskolc, each of the seven EU projects were introduced together with their respected geochemical aspects by overview presentations (CHPM2030 by Eva Hartai, Geowell by Pierre Durst, DESCRAMBLE and GeMEX by Giordano Montegrossi, MATchING by Ben Laenen, DESTRESS by Simona Regenspurg, SURE by Joerg Zotzmann). In the afternoon, scientific presentations were given on the following topics: fluid-rock interactions, monitoring, fluid characterization, and metal mobilization. The second day of the workshop was dedicated to discussions on questions that came up on the day before. These included:

• Mining of valuable compounds from fluids: What is the legislation background for mining from geothermal fluids?     
• Is the timeline of CHPM2030 feasible (2030: pilot; 2050 full operation)?
• Where can good data and databases of geothermal fluid chemistry and validated thermodynamic data for high temperatures, pressures, and high salinities be found?
• Radioactive components  in  geothermal  fluids:  better  keeping  them  in  solution  (use  of  inhibitors) or remove them by controlled scaling?  

Eventually, the discussion turned to future projects and calls that allow future collaboration. Tamas Madarasz and Chris Rochelle showed an overview of current and future EU calls potentially of interest  to the group.
