Today’s geothermal (aka hydrothermal power) is very limited because it requires a location with large amounts of naturally occurring superheated water trapped close to the surface.
Enhanced Geothermal or EGS is a new technology that can make geothermal energy widely available by creating underground reservoirs that allow water flow & heat extraction.
EGS is often compared to fracking in the oil & natural gas industry, but many differences make EGS far safer and cleaner.
Modern geothermal technology like EGS & AGS use closed-loop systems that emit almost no greenhouse gasses or pollutants.
Rain or shine, still or stormy, Geothermal keeps providing stable, clean power 24/7, 365 days a year.
Advanced Geothermal Systems or AGS bring many of the advantages of EGS but don’t need high-pressure fracturing to allow water flow.
Geothermal energy has the smallest land footprint of any comparable energy source in the world.
Like all energy sources, geothermal takes water to build & run.
Geothermal or ground source heat pumps can heat and cool homes & buildings at a fraction of the cost of traditional heating & AC.
Geothermal runs on heat & people have applied this heat to a myriad of uses beyond generating electricity.
From drill operators to maintenance crews to geologists, many stand to benefit from good-paying jobs in the burgeoning geothermal industry.
Deep EGS is the final frontier of geothermal power. Deep EGS wells can go to depths past 5, 7 or even 9 km to generate heat and electricity anywhere efficiently.
The DOE, industry and others are making huge strides in developing better & cheaper drilling technology.
Installing geothermal today costs about double that of wind, solar, and hydropower, but its high efficiency makes up the difference.
