Geothermal energy gains bipartisan support, focusing on enhanced geothermal systems

Bipartisan Legislative Support for Geothermal Energy

In a rare display of agreement, US politicians from both the Democratic and Republican parties are advocating for geothermal energy. The support stems from its low greenhouse gas emissions appealing to liberals while conservatives appreciate energy independence and reliance on familiar drilling technology.

Introduction of the Next-Generation Geothermal Act

In April, US senators introduced the Next-Generation Geothermal Research and Development Act. This legislation aims to instruct the Department of Energy to boost the development and commercialization of advanced geothermal energy systems, with an emphasis on enhanced geothermal systems (EGS).

Understanding Enhanced Geothermal Systems (EGS)

EGS involves hydraulic fracturing to access underground heat by creating fractures, thus allowing for the extraction of steam or hot water. Although similar to hydraulic fracturing methods used in the oil and gas industry, proponents argue that EGS offers significant environmental benefits.

Technological Innovations in Drilling

Advancements in drilling technology are essential for tapping into deeper geothermal energy sources. Companies are working on more stable drilling techniques, with some exploring non-traditional methods such as millimetre wave drilling developed by Quaise, which uses electromagnetic waves to penetrate hard rock.
