The article discusses the controversial method of fracking and its unexpected connection to geothermal energy production. Fracking, also known as hydrofracturing or hydraulic fracturing, involves pumping fluid into shale formations to extract oil and gas deposits. While initially rare in the US, advancements in technology and relaxed regulations led to a fracking boom with various environmental and public health impacts. Interestingly, geothermal energy researchers played a role in improving fracking technology in the 1980s, leading to the development of key drilling technologies for shale production. The article explores how enhanced geothermal systems, made possible by fracking, can significantly expand geothermal energy production in the US by utilizing hot rocks through the introduction of fluid and creation of porosity. While this technology has the potential to revolutionize geothermal energy, challenges such as water usage, chemical treatment, and cost-effectiveness remain. Researchers are exploring innovative solutions like a non-toxic hydrogel-based fluid to address some of these challenges. Despite the obstacles, the Energy Department is dedicated to advancing enhanced geothermal systems, as evidenced by projects like the FORGE geothermal research facility in Utah. This facility aims to fine-tune enhanced geothermal systems for commercial use, signaling a commitment to clean energy innovation in the United States.
