Assessing feasibility of subsurface heat storage to generate flexible electricity
A project on geothermal energy furthered the understanding of the feasibility of utilizing abandoned oil and gas wells as geothermal heat storage wells. This DOE-funded project addressed the challenges of energy supply intermittency by storing energy from renewable resources in the subsurface to harvest it at a later time during at-peak energy demand, enhancing grid resilience and reliability. Members of the Projeo team worked through a prestigious Small Business Technology Transfer (STTR) grant and participated in the Energy I-Corps training program to work towards the advancement and commercialization of this novel approach.
In this project, Projeo and its research partners assessed the heat storage and hydrogeological characteristics of subsurface reservoirs to determine the temperature profile and used the baseline data for modeling and simulation to determine other well locations.
