Development, Monitoring, and Control of Fracture Thermal Energy Storage in Crystalline Rock Formations
DEMO FTES
Call 2 2019
The DEMO FTES project will experimentally measure the thermal efficiency and capacity of fracture thermal energy storage (FTES) at the laboratory scale and in an approximately 10 m scale multi-month field test. FTES is a method of seasonal underground thermal energy storage (UTES) where an efficient heat exchanger connecting multiple wells is created using carefully designed hydraulic fractures. The technique would allow for inexpensive, high-capacity thermal storage in much larger geographical areas than current technology allows, offering a path to significantly reduce energy usage and greenhouse gas emissions from the heating and cooling of buildings. Laboratory testing is planned at the Geo-Energy lab at EPFL Lausanne, while the field test is planned at an existing highly instrumented testbed at the Sanford Underground Research Facility (SURF) in the U.S.
