Superhot geothermal energy could unearth big power boost for the AI era

For centuries, geothermal energy has been harnessed for heating, dating back to the 14th century, but now it is on the brink of a significant transformation. Enter superhot geothermal energy, a groundbreaking approach that utilizes ultra-deep drilling techniques to tap into extremely hot rocks, potentially yielding five to ten times more energy per well than traditional methods. Massachusetts-based startup Quaise Energy is at the forefront of this innovation, developing technology that employs an electromagnetic beam to vaporize rock. Their system is capable of reaching superhot geothermal energy sources up to 12 miles beneath the Earth's surface, where temperatures can soar to 500 degrees Celsius (over 930 degrees Fahrenheit). Carlos Araque, CEO of Quaise, emphasized the need for deeper and hotter drilling to access substantial geothermal resources. He noted, "To access the resource at a scale that actually matters, we have to drill hotter first and deeper second." The oil industry typically drills to depths of 2 to 3 miles, where temperatures rarely exceed 150 to 200 degrees Fahrenheit, making the leap to superhot geothermal essential for significant energy production. Quaise's technology, which originated at the Massachusetts Institute of Technology in 2007, is currently being scaled for commercial application. In June, the company successfully demonstrated its capabilities in collaboration with oil and gas giant Nabors Industries. While the initial drilling costs are higher, the substantial increase in energy output promises overall cost savings. Araque revealed plans for the world's first superhot geothermal power plant, aimed at showcasing the tenfold energy output achievable through this innovative approach. The pilot plant is set to be constructed near Bend, Oregon, with hopes for completion by 2028. Nabors Industries views this endeavor as a timely investment, given the growing demand for power driven by data centers, artificial intelligence, and the electrification of various sectors. Guillermo Sierra, vice president of energy transition at Nabors, remarked on the technology's potential to repurpose a significant portion of the workforce currently engaged in oil and gas. At a geothermal event held in Washington, D.C., in March, Secretary of Energy Chris Wright expressed strong support for geothermal energy, linking its advancement to the growth of artificial intelligence and manufacturing while also addressing electricity cost reductions. Notably, geothermal energy was highlighted by former President Donald Trump in his National Energy Emergency executive order, alongside nuclear and hydropower. Recent legislative developments have reinforced funding for geothermal initiatives, maintaining support originally included in the Biden administration's Inflation Reduction Act, despite cuts to other renewable energy sources.
