Dangerous Volcano in Oregon Could Power Homes with Super-Hot Geothermal
Published · 3 min read
Engineers in Oregon are working to tap the heat of one of America’s most dangerous volcanoes, the Newberry Volcano, to generate clean, powerful energy. The plan could be a major breakthrough in geothermal technology.
What’s the Project About
- Mazama Energy, a startup, is building a “super-hot rock” geothermal system inside Newberry Volcano in central Oregon.
- They have already drilled down and reached rock temperatures of 629°F (331°C), a record for this type of geothermal work.
- The goal is to push that temperature even higher — possibly to 750°F (400°C).
- This super-hot geothermal system could produce much more energy than traditional geothermal plants — because hotter rock gives off more heat.
- To do this, Mazama injects water into dry hot rock, which creates steam and powers turbines. This method is called enhanced geothermal energy.
Why It’s a Big Deal
Cleaner Energy, Bigger Impact
- Geothermal energy currently provides less than 1% of the world’s electricity.
- If this project succeeds, it could help raise that share significantly — potentially to 8% by 2050, according to experts.
- Mazama hopes to start producing 15 megawatts (MW) next year and scale to 200 MW.
- Theoretically, super-hot geothermal at Newberry could reach 5 gigawatts (GW) in capacity — that’s huge, and could power a large portion of Oregon.
Innovation Under the Volcano
- Traditional geothermal systems rely on natural underground water. That limits where they can be built. This super-hot system works even where water is not present.
- To drill into super-heated rock, Mazama must use new technology. They are experimenting with liquid CO₂ cooling, which helps drill bits survive extreme temperatures.
- This innovation could unlock geothermal energy in places previously considered unusable, making it a much more widely available clean energy source.
Risks and Challenges
- Injecting water into rock to create steam can trigger small earthquakes. Engineers admit this risk, but they believe the earthquakes can be managed.
- Drilling in super-hot conditions is very difficult — it’s hard to find materials that can survive that heat.
- There are also questions about cost: deep drilling is expensive, and building a whole power plant underground is a big financial bet.
What Experts Say
- Some climate and energy experts are excited: if super-hot geothermal works, it could become a reliable, 24/7 clean power source — unlike solar or wind, which depend on sun or wind.
- Others warn that the technology is still unproven at this scale. It may take years before it delivers on its full promise.
- If Mazama succeeds, it could spur more investment in geothermal around the world, not just in volcanic areas.
Why This Matters for Us
- As the world pushes to reduce carbon emissions, clean baseload (constant) energy is more important than ever. Super-hot geothermal could help provide that.
- This kind of power could help reduce reliance on fossil fuels for meeting both current energy demand and future growth.
- If scalable, the technology could be used in other volcanic or geologically hot regions, greatly expanding the reach of renewable energy.
- For local communities in Oregon, the project could bring new jobs and clean power — helping the region become a leader in next-generation renewable energy.
What’s Next
- Mazama Energy aims to begin power production in 2026, according to the project timeline.
- Engineers will continue drilling, testing, and refining their technology to safely and effectively extract heat from super-hot rock.
- If successful, the model could be replicated in other volcanic regions of the world.
- Policymakers and investors will watch closely: this could be a turning point for geothermal energy.
Final Thought
Turning a dangerous volcano into a power source sounds like science fiction — but right now, it’s science fact. The Newberry Volcano geothermal project by Mazama Energy could unlock some of the hottest energy on Earth and provide a powerful, carbon-free source of electricity. If it works, it’s not just a win for Oregon; it could be a win for the global fight against climate change.
