What The Experts Say

performance of eavor loop

NREL – Techno-economic performance of Eavor-Loop 2.0

This project evaluated techno-economic performance for a sample Eavor-Loop 2.0 design for electricity production and direct-use heating. The Eavor-Loop 2.0 design investigated is a 7.5-km deep closed-loop geothermal system consisting of 12 laterals for a total of more than 90 km of downhole well and lateral length.

Eavor-Loop audit report

TNO – Eavor-Loop™ Audit Report

Eavor has proposed an innovative well design for geothermal energy production, the Eavor-Loop™ . The Eavor Loop consists of a closed loop system, in which heat is extracted from the deep subsurface through multi lateral wells acting as effective heat exchangers.

Eavor-Loop™ Dispatchability Case Study for PPA with Utility

Eavor-Loop™, a multilateral closed loop geothermal system, is a clean firm power generation technology that can be scaled to phase out fossil fuel baseload and peaker plant generation. Eavor has partnered with a major US utility for the large-scale development of Eavor-Loops to supply clean firm power to the grid. The favorable geothermal gradients in the region, coupled with the scalability of the Eavor-Loop™ solution, indicate that there is >1.2GW of potential Eavor-Loop™ generation on the selected project licence area located in southwestern USA.

The Role of Clean Firm Power Generation in a 2050 Net-Zero Electricity Grid

Utility solar and wind generation play a large role in the pathways to a 24/7 carbon free energy future, especially considering that these resources are (and likely will remain for the coming decades) the least expensive form of electricity generation. While they are a central part of the mix, wind and solar alone will be insufficient. The intermittent nature of wind and solar, combined with their increased adoption in the grid, will create resiliency challenges towards meeting energy demand hour-by-hour, year over year.

Joint Development Between Eavor and Turboden

Eavor’s proprietary geothermal power technology consists of two vertical wells connected by one or more passes designed to circulate a working fluid in a closed loop system, with no interaction with the underground formation water, to supply heat at the surface.
Turboden Organic Rankine Cycle (ORC) Technology converts the heat available at the surface into electricity by means of a closed thermodynamic process involving a suitable working fluid which is heated up in a heat exchanger and expanded in a turbine to generate electricity.
