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.
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.
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.
The Eavor-Loop™, a multilateral closed loop geothermal system (MCLGS), is introduced as a zero-emission load-following resource (ZELFR) that is globally scalable and can provide baseload or dispatchable electricity…
Eavor-Lite™ is a full-scale demonstration project of a multilateral closed-loop geothermal system. An update is presented based on ~16 months of operations and testing. The project is located near Sylvan Lake, Alberta, Canada and consists of two 1.7 km long multilateral horizontal wellbores connecting two 2.4 km deep vertical wellbores to create a U-tube shaped closed-loop geothermal system.
The production of heat and electricity from geothermal energy is an old concept and has been around since the early 1900’s. However, many geothermal projects are plagued by high up-front exploration costs, financing difficulties and geological risk of low permeability reservoirs which limits development past the exploration phase.
Results from a full-scale demonstration project of a multilateral closed-loop geothermal system are presented. The project is located near Sylvan Lake, Alberta, Canada and consists of two 2.5 km long multilateral horizontal wellbores connecting two 2.4 km deep vertical wellbores to create a U-tube shaped closed-loop geothermal system.
