| Project Detail |
Fervo Energy has developed proprietary geothermal technology—FervoFlex™—capable of delivering in-reservoir energy storage and dispatchable generation attributes. At the same time, the team will develop a fiber optics-based diagnostic platform to monitor and optimize dynamic subsurface processes that currently pose major barriers to flexibly operating geothermal facilities. Fervo’s horizontal well design connects subsurface wells with a set of hydraulically conductive fractures surrounded by impermeable rock. These fractures act as flow pathways, providing contact areas with the geothermal reservoir to enable sustained heat recovery, and the low-permeability rock prevents fluid leak-off. Charging and discharging cycles are performed by controlling the injection and production well flow rates and pressures to deliver flexible generation profiles in response to grid demands and time-shift energy at high round-trip efficiencies. The FervoFlex™ technology effectively enables Fervo to operate their assets to achieve multi-day energy storage attributes in addition to the traditional benefits of clean, firm geothermal power.
Potential Impact:
Firm, zero-carbon, dispatchable resources are key to unlocking a fully decarbonized electricity sector. |
