Closed-Loop Geothermal Systems: Companies, Technology, Investment, Power

Closed-Loop Geothermal Systems: The Companies Building the Next Generation of Underground Energy Image : The Eavor Technologies Geothermal Project  Closed-loop geothermal systems represent one of the most promising frontiers in renewable energy, offering continuous, baseload power without the environmental concerns associated with conventional geothermal development. Unlike traditional open-loop systems that require hydraulic fracturing and consume large volumes of water, closed-loop geothermal circulates a working fluid through sealed underground pipes, extracting heat from hot rock formations while maintaining a self-contained system that eliminates fluid loss, induced seismicity, and reservoir depletion risks.This technology has attracted significant investment and technical innovation from a diverse array of companies spanning startups, established energy firms, and drilling specialists, each pursuing distinct approaches to unlock the vast thermal energy stored beneath the Eart...

Dow and X-energy advanced mobile reactor at an industrial site under US DOE the Advanced Reactor Demonstration Program

Dow has partnered with X-energy under the Advanced Reactor Demonstration Program (ARDP) Cooperative Agreement with the US Department of Energy (DOE) to install their Xe-100 high-temperature gas-cooled reactor (HTGR) plant at one of Dow's sites on the US Gulf Coast.

This collaboration aims to provide safe, reliable, and low-carbon power and steam to the site within this decade. The Joint Development Agreement (JDA) includes up to $50 million in engineering work, with half of it to be funded by Dow and the other half eligible for funding through ARDP. The JDA also involves the preparation and submission of a Construction Permit application to the US Nuclear Regulatory Commission (NRC).


Dow's Chairman and CEO, Jim Fitterling, stated that the use of X-energy's nuclear technology will enable Dow to reduce its carbon emissions and deliver lower-carbon footprint products to its customers and society. The parties expect to finalize site selection in 2023, subject to DOE review and approval. Dow and X-energy plan to undertake further ARDP-related work under the JDA as the project progresses. The companies have also agreed to develop a framework to jointly license and utilize the technology and learnings from the project, allowing other industrial customers to leverage Xe-100 industrial low carbon energy technology.


X-energy's HTGR technology is more advanced than existing light water and other small modular reactors, as it can support broad industrial applications through its high-temperature heat and steam output, which can be integrated into and address the needs of both large and regional electricity and/or industrial manufacturing systems. The four-reactor Xe-100 nuclear plant will provide a Dow facility with cost-competitive, low-carbon process heat and power to make essential products used by consumers and businesses every day. X-energy's modular design is road-shippable, which is intended to drive scalability, accelerate construction timelines and create more predictable and manageable construction costs.


X-energy was awarded up to $1.2 billion under the ARDP in federal cost-shared funding to develop, license, build, and demonstrate an operational advanced reactor and fuel fabrication facility by the end of the decade. Since the award, X-energy has completed the engineering and basic design of the nuclear reactor, advanced development of a fuel fabrication facility in Oak Ridge, Tennessee, and is preparing to submit an application for licensure to the NRC. The collaboration between Dow and X-energy serves as a leading example of how the industrial sector can safely, effectively, and affordably decarbonize and reduce emissions in the energy-intensive industrial sector.

Quaise Energy Secures DOE Funding for Superhot Geothermal Plant

Quaise Energy Wins DOE Support for Project Obsidian as Superhot Geothermal Moves Toward Commercial Scale Quaise Energy’s selection for up to $25 million in U.S. Department of Energy support is a meaningful milestone for superhot geothermal power, especially because it is tied to Project Obsidian, the company’s flagship commercial-scale Enhanced Geothermal System in Central Oregon. The award strengthens the case that superhot geothermal is shifting from laboratory promise toward field-tested infrastructure, with the first well triplet designed to validate a path to more than 25 megawatts of gross electric power and future expansion potential much larger than that.  DOE backs superhot geothermal The U.S. Department of Energy selected Quaise under its Next-Generation Geothermal Field Tests and Geothermal Resource Characterization and Confirmation funding opportunity, part of a broader $99 million geothermal push announced this week .According to DOE, the selected projects are mean...

France Geothermal Energy 2026: Heating, Power, Policy, Investment Growth

France's geothermal sector is at a crossroads. The country is Europe's undisputed leader in deep geothermal district heating, with the Paris Basin hosting the world's largest concentration of deep geothermal systems.  Yet geothermal still supplies only 1% of France's final heat consumption, and the Court of Auditors has warned that current ambitions are "unrealistic" without structural reform. ⚡ Deep Geothermal (Power Generation): Marginal Output, Major Potential Untapped France's geothermal power generation remains almost negligible. As of 2026, only two plants produce electricity: the Bouillante plant in Guadeloupe (15.5 MW) and the Soultz-sous-Forêt EGS pilot in Alsace (1.7 MW).  Total geothermal electricity production capacity was approximately 17.17 MW in 2023, forecast to reach just 19.47 MW by 2028. The Bouillante plant is set to double its production with a third unit scheduled for commissioning by the end of 2026, making it an exemplary model for ...

Global Geothermal Policy Outlook for 2027 Across Key Markets

Global Geothermal and Energy Policies for 2027: A Future Outlook Introduction The next phase of global geothermal development will be shaped not only by geology and technology, but increasingly by national energy policy . Governments are now treating geothermal as more than a niche source of heat or power . They are beginning to see it as a practical option for firm low-carbon electricity, district heating, industrial heat, and energy security. That shift matters because geothermal projects are unusually sensitive to policy design. Exploration is capital intensive, drilling is expensive, subsurface risk is real, and project timelines can stretch over years before revenue begins. In other words, geothermal is not just an engineering challenge. It is also a finance, regulation, and infrastructure challenge. Looking toward 2027, five countries offer a useful benchmark for where geothermal policy may be heading: the United States, the United Kingdom, Norway, Canada, and France. Each countr...
