Chiyoda and Sage Geosystems Advance Next-Generation Geothermal Chiyoda Corporation and Sage Geosystems have signed a memorandum of understanding to conduct a technical and commercial feasibility study for high-pressure surface facilities tied to Sage’s proprietary enhanced geothermal systems approach. The announcement is an important step for next-generation geothermal because it focuses on the infrastructure needed to turn deep subsurface energy into reliable commercial power. The study is not a full build decision, but it is the kind of engineering work that usually comes before one. It will help determine whether Sage’s pressure-based geothermal concept can be translated into a scalable, bankable power-generation system. What the partnership covers The collaboration centers on the surface equipment required to handle high-temperature, high-pressure fluid produced from wells. Sage will provide key operating inputs, including wellhead pressure, temperature conditions, fluid proper...
Quaise Energy Raises $180 Million as Superhot Geothermal Moves Closer to Commercial Reality Quaise Energy has taken a major step toward commercializing superhot geothermal power with the final close of its Series B financing, bringing in $180 million in equity capital and lifting total funding to $280 million. The round includes a $35 million investment from Nabors Industries and a strategic framework agreement that strengthens the companies’ collaboration around drilling operations, technology integration, and commercial development. The announcement matters because it is not just another clean-energy funding headline. It is a signal that superhot geothermal is starting to attract the kind of capital, industrial partnerships, and technical confidence that are usually needed before a frontier energy technology can move from laboratory promise to real-world deployment. A Big Capital Milestone The final close of the Series B gives Quaise a stronger financial base to advance Project Obs...
