Enhanced Geothermal System is a project that is being implemented in the State of Nevada and is being recognized by the Energy Department as the first commercialized energy being directly supplied to the grid.
To generate electricity, the Desert Peak EGS project utilizes a production well at a previously built geothermal site in Churchill County.
This project has increased its power output by nearly 38 percent thus providing an additional 1.7 megawatts of power to the grid.
Below is an infographic that explains how a enhanced geothermal system works.
Leveraging a $5.4 million Energy Department investment—matched by $2.6 million in private sector funding—the Ormat Desert Peak project is extending the life of previously unproductive geothermal wells.
Now if you are worried about the amount of water being used to get the heat to the surface, do not. It has a initial amount pumped in but then it is utilized in a closed loop process.
This is a great start in utilizing untapped resources for use versus coal burning or fracking. However, should fracking be approved in nearby areas, it could cause some issues for this project. But I doubt this will happen.
