Geothermally Sourced Combined Power and Freshwater Generation for Eastern Africa

The Geothermally Sourced Combined Power and Freshwater Generation for Eastern Africa (Combi-Gen) project aims to deliver enhanced power and water resource capabilities to energy-poor and water-scarce nations associated with the East African Rift System (EARS). The Combi-Gen project utilises a robust understanding of geothermal resources and develops a novel thermal chimney driven air-cooled condenser coupled to Trilateral Flash Cycle power generation. This whole systems approach allows for development of a system that produces power and fresh water with no parasitic power load. This paper reports our initial data assessment and modelling results which showcase optimal thermal exchange efficiency parameters and engineering system design
