Hydrogen, solar, wind—and even microwave beams from outer space—are a few of the alternative energies being explored as the world strives to cut the cord on carbon emissions. Recently, advancements in geothermal energy technologies appear poised to significantly expand geothermal’s reach. These new methods are varyingly referred to as engineered, enhanced or advanced geothermal systems (collectively referred to here as EGS), have recently made strides in scalability and grabbed the attention of changemakers and, if successful, may lead to EGS playing a major role in the clean energy transition. The technique creates no emissions and is virtually limitless (it pulls from heat generated by the Earth’s core), and can provide constant baseload power, making it appealing to green-minded investors. This article calls attention to the progress and variety of EGS projects and proposals that Pillsbury sees as part of the ongoing energy transition.
