Volcano Power: Earth's Hottest Geothermal Plant Nears Reality

On the slopes of Oregon's Newberry Volcano, engineers are constructing a groundbreaking geothermal power plant designed to harness unprecedented heat levels. This facility, situated on one of the United States' most hazardous active volcanoes, is projected to reach temperatures exceeding 750 degrees Fahrenheit, a threshold that unlocks the potential of 'superhot rock' energy.

This initiative, spearheaded by Mazama Energy, represents a significant leap for geothermal power. Unlike conventional sites limited by natural water availability, this project employs enhanced geothermal methods by injecting water into fractured hot rocks. While this carries risks of seismic activity, such as tremors recorded at the site, careful monitoring aims to mitigate these concerns.

The ambition is to make geothermal energy a consequential global power source, potentially increasing its share of world electricity from less than 1 percent to 8 percent by 2050. The ability to tap into superhot rock, where water becomes supercritical, offers five to ten times more energy than typical geothermal wells, promising lower costs and wider applicability.
