A congressional subcommittee has advanced three energy-related bills that push for technological innovation in geothermal energy development, battery storage, and power grid modernization—innovations that could help to slow greenhouse gas emissions.
One of the bills, the Advanced Geothermal Research and Development Act of 2019 (H.R. 5374), “takes important steps toward advancing a woefully underutilized source of energy,” said Rep. Sean Casten (D-Ill.) at the 19 December markup of the legislation by the Subcommittee on Energy of the House Committee on Science, Space, and Technology.
The legislation, which was introduced by the full committee’s ranking member Rep. Frank Lucas (R-Okla.), was approved with bipartisan and unanimous support, as were the other two bills. The bills now go to the full committee for consideration.
Geothermal energy, which is literally heat derived from Earth, contributes to just 0.4% of electric power generation in the United States, according to the Energy Information Administration of the U.S. Department of Energy (DOE). Although the United States already generates more total power from geothermal sources than any other country, proportionately, it pales in comparison with geothermal leaders like Iceland, which gets 26% of its total electric power generation from geothermal, according to a report by the Atlantic Council, a Washington, D.C.–based think tank.
A 30 May DOE report, GeoVision: Harnessing the Heat Beneath Our Feet, noted that there is enormous untapped potential for geothermal electricity generation in the United States from “vast and geographically dispersed” resources. These resources aren’t just located near volcanically and hydrothermally active areas like Yellowstone National Park; rather, the report stated, “Shallow-earth resources exist across all 50 states and can be used for [geothermal heat pumps] wherever the ground can be cost-effectively accessed to depths below seasonal temperature variations.”
The report found that by 2050, geothermal power generation could increase more than 26-fold from today and reach 60 gigawatts of installed capacity, providing 8.5% of all U.S. electricity generation. However, “challenges in resource exploration, drilling, and development present fundamental barriers to improved economic capture of geothermal resource potential.”
