Quaise Energy said it is moving ahead with plans to build what it describes as the world’s first power plant using superhot geothermal energy, with an initial 50-megawatt facility planned in Oregon.
The Houston-based startup said the first phase of Project Obsidian is already under construction and could begin operations as early as 2030.
The company said an internal analysis presented at the 2026 Stanford Geothermal Workshop supports output of at least 50 MW of always-on renewable electricity from a small number of wells.
Superhot geothermal refers to tapping rock hotter than 300°C (572°F). At such temperatures, geothermal wells can potentially deliver far more energy than conventional systems while using less land.
The company said later expansions at the same site could lift output to 250 MW, with longer-term plans reaching 1 GW.
