While President Donald Trump’s rhetoric focuses on the Strait of Hormuz, a quieter financial wave is rising in the United States: a $134 million Series B round for deep‑drill geothermal startup Quaise Energy. If the technology lives up to its promises, it could provide 24/7 baseload power that sidesteps the geopolitical choke points of oil and gas shipments, aligning with the President’s “American Energy Dominance” narrative yet remaining untested at scale.[1]
Deep Dive
Quaise’s appeal stems from a new drilling approach that creates artificial geothermal reservoirs or reaches temperatures of 300‑1,500 °C far below the surface. The company says this method can deliver “10 to 100 times more power” than conventional geothermal wells, potentially making sites far from traditional heat‑rock‑water intersections viable power generators.[2]
By drilling onsite at thermal generation plants and industrial centers to utilize the existing infrastructure and workforce, a faster energy transition becomes possible,
The financing picture underscores growing investor confidence. After a $21 million Series A1 raise in February 2025, Quaise secured an additional $13 million in March 2025, and most recently closed a $134 million Series B round. The round was led by Prelude Ventures, with strategic investments from Japan’s JERA and Idemitsu, two of the country’s largest energy companies. Nearly all existing investors, including Safar Partners, participated in the round.[3] Safar’s partner Parinaz Motamedy noted that the raise “represents an important inflection point as the company transitions from scientific breakthroughs to commercial deployments.”[4]
JERA’s involvement is notable for two reasons. First, it signals Japan’s interest in leveraging deep‑drill geothermal to tap one of the world’s largest untapped geothermal resources. Second, the investment is tied to Project Obsidian, a planned geothermal plant in Oregon that will serve as a demonstration site for the technology. JERA notes that “the companies will also explore potential opportunities related to the future commercialization and deployment of the technology in Japan.”[5]
Beyond private capital, federal agencies are also in the mix. The U.S. Department of Energy has provided research support for Enhanced Geothermal Systems, while the U.S. Air Force has pre‑qualified a group of geothermal innovators—including Quaise—for future contracts. This dual backing suggests the technology is being evaluated not only for civilian power markets but also for strategic resilience in defense installations.[6]
From a geopolitical standpoint, the promise of domestic baseload power could reduce reliance on imported fuels and the shipping lanes that have historically been flashpoints, such as the Strait of Hormuz. Geothermal’s ability to generate electricity continuously, irrespective of weather, offers an alternative to intermittent renewables that still require backup generation from fossil sources.[7]
However, the path from pilot to grid‑scale deployment is littered with practical hurdles. Deep‑drill systems require specialized millimeter‑wave drilling rigs, which are not yet mass‑produced, potentially driving up capital expenditures. While leveraging existing plant sites may streamline permitting, federal and state regulators still demand extensive environmental impact studies for subsurface activities, especially when drilling beyond traditional depths.[8]
Financially, the concentration of capital in a handful of investors raises questions about long‑term funding stability. The Series B round’s reliance on strategic corporate investors from Japan could expose the project to foreign‑policy shifts or currency fluctuations, factors not discussed in the source material.[9]
Audit & Contradictions
The CleanTechnica piece provides the primary data points for Quaise’s funding, JERA’s strategic investment, and the baseload claim. Independent corroboration from other outlets confirms the general growth of Enhanced Geothermal Systems research but does not verify every specific figure or the full scope of Project Obsidian. Accordingly, statements about funding amounts and investor participation are presented with attribution to the source article.[10]
Future Outlook
If Quaise’s technology scales, it could reshape the U.S. energy map by turning previously unsuitable regions into power‑generation zones, potentially attracting other investors and prompting state regulators to draft new permitting frameworks for deep‑drill geothermal. Competing clean‑energy firms—particularly solar and wind operators—may need to reassess their baseload strategies, as geothermal could offer a stable complement rather than a direct substitute.[11]
On the policy front, the administration’s emphasis on energy security could translate into incentives for projects that reduce exposure to foreign oil supply disruptions. Yet, without clear federal tax credits or loan guarantees for deep‑drill geothermal, market uptake may remain limited to well‑funded pilots like Project Obsidian.[12]
Internationally, JERA’s involvement hints at a future where Japanese utilities partner with U.S. innovators to export geothermal know‑how, potentially creating a trans‑Pacific supply chain for drilling equipment and expertise. This could accelerate the commercialization of high‑temperature resources in regions beyond the traditional Western U.S. corridor, aligning with the broader claim that such resources exist “deep underground in most regions of the world.”[13]
In sum, the recent funding surge spotlights a technology that could address both domestic energy security and geopolitical vulnerabilities, but the lack of independent verification, detailed cost analysis, and regulatory clarity means the promise remains speculative until a commercial plant proves its economics at scale.
