Ethiopia Renegotiates Key Deals to Restart Multimillion‑Dollar Geothermal Projects: Tulu Moye and Corbetti Move Toward Restart After years of security disruptions, financing shortfalls and contract disputes, two of Ethiopia’s highest‑profile geothermal concessions , the Tulu Moye (Meridiam/Reykjavik Geothermal) and Corbetti projects , are actively renegotiating with senior government authorities to resume development. The talks mark a practical pivot from litigation and prolonged suspension toward restarting drilling and project implementation, with implications for Ethiopia’s energy mix, investor confidence and the regional geothermal supply chain. Why these renegotiations matter For an emerging geothermal market like Ethiopia, the fate of Tulu Moye and Corbetti matters on three fronts: capacity and grid impact, investor signaling, and the country’s ability to mobilize large, foreign‑led project finance. Each project alone represents several hundred megawatts of potential dispatchable...
Unlocking Earth's Infinite Power: The Revolution of Millimeter Wave Drilling
In a groundbreaking test at the Quaise laboratory, scientists have taken a monumental step toward tapping into the boundless reservoir of clean energy that lies deep beneath the Earth's surface. This untapped potential, which could power our civilization for millions of years, is now within reach thanks to an innovative technology: millimeter wave drilling.
The Hidden Treasure Below
Deep geothermal energy holds the promise of providing clean, sustainable power 24/7. Unlike solar or wind, which are intermittent, geothermal energy is constant, driven by the Earth's internal heat. However, accessing this energy, buried deep within the tough, crystalline basement rock, has long been a challenge. Traditional drilling methods falter here, where high pressure and temperature wear down mechanical drill bits rapidly, making the process expensive and inefficient.
Enter Millimeter Waves
Millimeter waves (MMWs), a segment of the electromagnetic spectrum between microwaves and infrared, offer a novel solution. These waves, with wavelengths measuring 1-10 millimeters, are all around us, used in technologies from 5G communication to fusion energy research. MIT engineer Paul Woskov saw their potential for geothermal energy. Working with gyrotrons, devices that produce high-power MMWs, Woskov envisioned a way to vaporize rock and unlock the Earth's deep heat reserves.
From Lab to Field
Woskov's research at MIT's Plasma Science and Fusion Center (PSFC) showed that MMWs could indeed vaporize tough rocks like granite and basalt. By directing these waves down a special metallic pipe called a waveguide, the MMWs melt and ablate the rock, turning it into fine ash that is then flushed to the surface. This method not only overcomes the limitations of traditional drilling but also promises to be significantly more cost-effective.
A Game Changer in Energy
Quaise has scaled up Woskov's lab tests dramatically, achieving a 100x increase in scale. The result is a hybrid drilling approach that combines conventional drilling through sedimentary rock with MMW drilling through basement rock. This method holds the key to unlocking deep geothermal energy almost anywhere on Earth, potentially making it 10 times more powerful than traditional geothermal energy sources.
The Path to Net Zero
The implications of this technology are profound. Deep geothermal energy could transform the global energy landscape, providing a reliable, clean power source that leverages existing infrastructure. As Quaise continues to refine and deploy this technology, the vision of a world powered by abundant, sustainable energy comes closer to reality.
Imagine a future where energy is no longer a constraint on human progress, where the power needed to drive industry, technology, and daily life is clean and limitless. This is the promise of millimeter wave drilling and deep geothermal energy—a future we can look forward to with hope and excitement.
Join them at Quaise as them embark on this journey to revolutionize energy. Together, we can turn the tide against climate change and create a world where clean energy is abundant and accessible for all.
