Session Proposal: Aiming for Superhot Rock Geothermal: Technological Advancements for Working in Extreme, Harsh Environments (AGU25)

V003
Aiming for Superhot Rock Geothermal: Technological Advancements for Working in Extreme, Harsh Environments

Session ID#: 246770

Session Description:
Geothermal is one of the few clean energy sources capable of delivering reliable, 24/7 baseload power. Conventional geothermal resources currently provide 0.4% of the total installed global power generation. Targeting temperatures >400 °C in the “superhot” environment is critical to unlocking the high-power potential of geothermal, creating a step-change in renewable power generation. Early research indicates increased capacity of superhot rock geothermal projects (5-10x a typical commercial geothermal well), however, these extreme, harsh environments challenge the successful development and operation of superhot rock geothermal projects. Successful development in high pressure, high temperature superhot rock environments calls for: 1) advancements in materials that can survive thermal cycling, 2) understanding supercritical fluid-rock and fluid-metal interactions, 3) fracture identification and behavior prediction, and 4) heat extraction for sustained productive geothermal reservoirs. We solicit abstracts on research aimed at bridging these gaps and encourage submissions across scientific domains to advance higher temperature geothermal projects.
