Report on performance, energy balances and design criteria for salt gradient power reverse electrodialysis

This deliverable is the output of Task 3.3 where the key points of investigation are: Knowledge about the potential of electricity generation with geothermal fluids (in a SGP-RE semi-pilot unit): • Performance of the technology with mixed metal model matrices • Performance of the technology with raw geothermal fluids (technological fluids circulating in a closed system) • Performance of the technology with pre-treated geothermal fluids (by the technologies described in Tasks 3.1 and 3.2) • Effect of influent temperature Generation of design criteria to improve process performance and control: • Framework of conditions of applicability of the technology to the removal and recovery of the metal content of geothermal fluids (based on results with model matrices, raw fluids, pre-treated fluids) • Establishment/improvement of reactor design criteria for further scalability • Process simulations based on experimental data (multiphysics calculations based on electrochemical engineering concepts) to optimize process parameters • Mass and energy balances (model compositions and actual raw fluids
