Eavor Demobilizes Rigs from Geretsried: What It Really Means for Closed-Loop Geothermal For three years, two drilling rigs on a farm estate near Geretsried, a Bavarian town about 40 km south of Munich, stood as the symbol of the world's most ambitious closed-loop geothermal experiment. Now in October 2026, Eavor Technologies, the Calgary-based developer of the Eavor-Loop, has told the town and its heating utility that both rigs would leave the site . The company said keeping idle rigs and specialist services on site was costly, and that releasing them would help put the project in the strongest position to continue with Loop 2 once its commercial structure is reworked . On the surface, this is a logistics decision. Underneath, it is one of the clearest signals yet about where first-of-a-kind geothermal technology stands, and how hard it is to turn a technical proof into a bankable business. This article explains exactly what happened, what the move means and what it does not mean...
A strategic bet on energy and chips
The U.S. Department of Commerce has awarded I-Pulse $250 million under the CHIPS Research and Development program to accelerate advanced semiconductor technologies with applications in geothermal drilling, manufacturing, mining, and defense . The award reflects a broader push to strengthen domestic semiconductor capability while supporting energy security and industrial resilience .
At the center of the project is a set of high-temperature silicon carbide semiconductor components and pulsed power systems designed to work in extreme environments. Those conditions matter because the same technology that can survive heat, pressure, and shock in drilling and defense can also help reduce reliance on foreign chip supply chains.
Geothermal energy has long promised reliable, around-the-clock clean power, but drilling deep enough to reach the hottest rocks is expensive and technically difficult . In many places, the cost of drilling has been the biggest obstacle to turning that potential into commercial projects.
That is where I-Pulse says its approach could change the equation. Instead of relying only on mechanical force, the company’s pulsed-power drilling platform sends extremely powerful electrical pulses into rock ahead of the drill bit, fracturing and softening it first . If that system works at scale, it could speed up drilling and extend drill-bit life, both of which can lower project costs .
How the technology works
I-Pulse is developing high-voltage, high-current solid-state switches that can operate in demanding conditions . These switches sit at the heart of pulsed power systems, which release energy in very short, intense bursts rather than in a steady flow . That burst of energy is what helps crack hard rock formations before the drill bit reaches them.
The company says this method is especially useful in hot granite formations, which are difficult to penetrate using conventional drilling alone . By reducing the mechanical burden on the drill bit, pulsed power drilling may make deeper and harder geothermal targets more practical . This is the kind of engineering improvement that can matter as much as a breakthrough in generation technology itself.
This is not the first time we are seeing companies thinking outside the box when it come to drilling, there's much coming, with most uncovered.

Why silicon carbide matters
The chips involved in this program are not ordinary semiconductors. Silicon carbide is valued because it can handle high temperatures, high voltages, and harsh operating conditions better than many traditional materials . That makes it suitable for equipment that must keep working where normal electronics would fail.
I-Pulse plans to develop these components with U.S. national laboratories, universities, and specialized manufacturers . The collaboration matters because the work is not only about building a single product; it is about creating a broader domestic capability in advanced semiconductor design and production .
Why the US is investing now
The award fits into a larger national strategy. Commerce Secretary Howard Lutnick said the investment would strengthen America’s industrial and security capabilities, tying the project directly to the Trump administration’s energy and national security goals . That framing shows how semiconductor policy is increasingly being linked to energy, defense, and manufacturing in one package .
The U.S. has also been trying to expand geothermal development more broadly. The Department of Energy announced funding earlier in 2026 to support next-generation geothermal field-scale tests, including exploration drilling and electricity generation work . Taken together, these efforts suggest that geothermal is becoming a more serious part of the country’s energy strategy .
What I-Pulse says it can unlock
I-Pulse believes lower drilling costs could make advanced geothermal power plants commercially viable in areas that were previously too expensive to develop . That is important because geothermal power has one major advantage over solar and wind: it can deliver continuous electricity, which makes it useful for data centers and industrial facilities that need stable power around the clock .
The company says its drilling platform could also support underground mining, rock crushing, manufacturing equipment, and defense systems that operate in harsh environments . In other words, the commercial upside is broader than one energy market. The same technology stack may serve multiple sectors that depend on high-power, ruggedized electronics .
The Albuquerque research hub
The research program will be led from I-Pulse’s Albuquerque facility, which sits near Sandia National Laboratories, a long-standing center for pulsed power research . That location is important because pulsed power has deep roots in U.S. national lab research and defense applications . Bringing it into the civilian sector is part of what makes this award notable.
Dr. Rick Spielman, President of I-Pulse Albuquerque and I-Pulse Group’s Chief Scientist, said pulsed power technologies were first used by Sandia in the 1960s to simulate weapons effects and are now being adapted for civilian products . That evolution from defense research to industrial use is a familiar pattern in American innovation .
A bigger industrial signal
This award is not just about one startup getting funding. It signals that Washington sees advanced semiconductors as a tool for solving several problems at once: stronger chip supply chains, better energy infrastructure, and more resilient defense technologies . That is why this story sits at the intersection of technology policy and energy policy.
For the geothermal sector, the key question is whether pulsed power can truly bring drilling costs down enough to change project economics . For the semiconductor sector, the question is whether silicon carbide production can be scaled domestically in a way that supports both industrial and strategic needs . If both happen, the payoff could be significant.
What comes next
The next phase will likely focus on research, testing, and commercialization of the high-voltage switching systems and related chip components . The company’s partnerships with laboratories, universities, and manufacturers will be central to that effort . Success will depend on whether the technology can perform reliably outside the lab and under real industrial conditions.
If it does, the implications could stretch well beyond geothermal wells. A technology that can survive extreme heat, handle high power, and reduce drilling costs could reshape how the U.S. approaches energy extraction, manufacturing, and defense hardware . That is why this $250 million award is getting so much attention.
Closing perspective
The I-Pulse award shows how advanced chips are becoming part of the energy transition, not just the digital economy . By linking silicon carbide semiconductors to geothermal drilling, the U.S. is betting that next-generation hardware can help unlock reliable power while strengthening domestic industrial capacity .
For readers tracking clean energy, semiconductors, or national security, this is a story about convergence. Energy security, chip independence, and industrial innovation are increasingly being treated as the same challenge . I-Pulse now has a major public-backed push to prove that concept in the real world .
