Tittel

Topside cycles for enhanced geothermal systems with CO2 and hydrocarbons as working fluids

Sammendrag

One concept for enhanced geothermal systems (EGS) described in recent literature is based on circulating CO2 through a reservoir where the thermosiphon effect becomes strong enough to sustain strong self-circulation such that both pressure and temperature differences can be utilized for power production topside. The topside system operation influences the thermosiphon-driven fluid mass flow and the state at production well. The total system behaviour must therefore be considered to maximize net power output. In this work, a case study is defined based on conditions representing a location on the Norwegian continental shelf. A system model comprising direct and hybrid (with additional ORC) systems, and a simplified well and reservoir flow- and heat transfer model is developed. Two solutions for topside systems are evaluated with the aim of maximizing net power production. Both direct expansion of the CO2 reservoir fluid, and a combination of direct expansion with an indirect ORC cycle are investigated.
