What is the 'superhot rock' technology being used at Newberry Volcano?

Superhot rock technology aims to harness energy from rocks heated to 705 degrees Fahrenheit or above, where water becomes supercritical and highly efficient for power generation.

How does Mazama Energy plan to reach extreme temperatures at Newberry Volcano?

Mazama Energy is drilling deep into Newberry Volcano, using innovative cooling techniques for drilling rigs to access rock temperatures exceeding 750 degrees Fahrenheit.

What are the risks associated with enhanced geothermal energy projects like Newberry?

Enhanced geothermal projects carry a risk of inducing minor earthquakes due to water injection into rock fractures, which can be managed with monitoring and engineering.

Summary

Newberry Volcano in Oregon is being developed into the world's hottest geothermal power plant.
The plant aims to reach over 750 degrees Fahrenheit to tap into 'superhot rock' energy.
This superhot geothermal could significantly boost clean energy's global share by 2050.

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.
