Conceptual Framework for CHPM power plant

This deliverable is connected to Task 4.1, which will convert outputs of WP1-WP3 into an overall architecture design of the envisioned CHPM facility by creating a model framework based on component level models which enables linking downstream and upstream geothermal engineering subsystems. Work will start with integrating downstream and upstream components into CHPM prototype concepts that will be evaluated for efficiency and resiliency. The development of the conceptual framework will build on existing component level models for binary or flash geothermal power plants, but will highly dependent on the outcomes of WP2 and WP3 to add metal recovery to the overall process flow. As such a definitive design concept cannot be produced at this stage. There is considerable interest in adapting a binary cycle when drafting the conceptual framework as this would keep the geothermal fluids with extreme concentrations of metals separated from the secondary cycle that drives the turbines. The advantages of starting for existing binary cycles include flexible adaptability to a range of temperature conditions and flow rates, with the main advantage being that it allows the conceptualisation of the CHPM plant as an entirely closed system with controllable environmental impact on the surface.
