Chiyoda, Sage Geosystems sign MOU for next-generation geothermal feasibility study

• Chiyoda signed an MOU with Sage Geosystems to run a technical and commercial feasibility study on next-generation geothermal power systems.
• Work targets high-pressure surface facilities for commercial-scale generation using Sage’s enhanced geothermal systems, designed to recover energy from high-temperature fluids.
• Study will assess equipment configuration, power and energy balances, indicative capex and opex, and implied power generation costs.
• Sage’s approach aims to support baseload power, with development also positioned toward long-duration energy storage using underground pressure.
• Project was selected for support under the Tokyo Metropolitan Government’s TIB CATAPULT program tied to the Zero Emission Tokyo strategy.
