The Retrofit Revolution: How GreenFire Energy Is Turning Abandoned Oil & Geothermal Wells Into Continuous Clean Power Without New Drilling

The Retrofit Revolution: How GreenFire Energy Is Unlocking Geothermal Power Without Drilling a Single New Well By: Robert Buluma   While much of the geothermal energy sector has been focused on breakthrough drilling techniques—deeper wells, hotter reservoirs, and complex engineered systems—a quieter revolution has been unfolding in the background. Instead of chasing entirely new subsurface frontiers, one company has chosen a radically simpler question: What if the answer was already in the ground? GreenFire Energy is advancing a retrofit-first geothermal strategy that targets one of the most overlooked opportunities in the global energy transition: existing wells that are underperforming, depleted, or completely abandoned. Rather than drilling new holes into the Earth, the company is reusing the infrastructure that already exists—turning stranded assets into continuous sources of clean, baseload electricity. This approach is not just technically elegant. It may also be one of ...

Deep Geothermal Sends Insurers on the drawing board

Insurers Planning Solutions for Deep Geothermal Energy


By Robert Buluma

In the pursuit of sustainable energy sources, deep geothermal energy has emerged as a promising avenue. However, challenges such as drilling risks and lack of insurance coverage have hindered its widespread adoption. Addressing these concerns, the Federal Ministry of Economics is deliberating solutions in collaboration with KfW, the federally owned development bank, to ensure the viability of deep geothermal energy projects.

The Need for Insurance Coverage:

One of the major obstacles faced by utilities and municipal utilities in implementing deep geothermal projects is the absence of insurance coverage. The uncertainty surrounding drilling success and the potential shortfall in expected heat production deter stakeholders from investing in such ventures.

Proposed Solution:

To mitigate these concerns, the proposed solution involves insuring the drilling success through KfW. Under this arrangement, if the projected heat production is not achieved, the entire insured amount will be paid out. In cases where the actual output falls short of expectations, a reduced payout will be made, with results verified by an assessor. This initiative aims to instill confidence among investors and facilitate progress in the transition to sustainable energy.

Industry and Government Support:

The idea of insuring drilling success has garnered support from both the energy industry and governmental bodies. While some drilling companies offer similar insurance options, they primarily target projects with a high likelihood of success. The endorsement of this measure underscores its importance in fostering innovation and investment in the geothermal energy sector.

Integration with Existing Initiatives:

Our very own  Robert Buluma  took his precious time to offer insights to this having encountered such a scenario on duty, here is what he had to say with original response in Germany.


This initiative aligns with the broader objectives outlined in the "Geothermal Energy Campaign" introduced by the ministry in 2022. By extending KfW loans to cover drilling risks, the campaign aims to incentivize the development of deep geothermal energy projects. This holistic approach underscores the government's commitment to advancing sustainable energy solutions.


The proposed insurance solution for deep geothermal energy projects represents a significant step towards overcoming barriers to implementation. By providing financial security and risk mitigation measures, stakeholders are encouraged to explore the potential of geothermal energy as a sustainable alternative.

With industry and government backing, initiatives like these pave the way for a greener and more resilient energy future.

Eavor steps back from operator role in the Geretsried geothermal project

Eavor at the Crossroads: What Geretsried Really Tells Us About the Future of Closed-Loop Geothermal By Alphaxioms Geothermal Insights | May 13, 2026 For years, Eavor Technologies was the geothermal sector's most talked-about enigma. The company raised hundreds of millions of dollars, attracted backing from heavyweights including BP , Chevron , Helmerich & Payne , and Temasek , and made bold promises about a proprietary closed-loop technology that would quietly revolutionise how humanity extracts heat from the earth. But it rarely said much in public. The secrecy was, to many observers in the geothermal community, a feature rather than a bug — protecting intellectual property, managing competitive intelligence, buying time. Now, Eavor is talking. And what it is saying is worth listening to very carefully. In an exclusive interview published on May 13, 2026, by GeoExpro editor Henk Kombrink, Eavor's new president and CEO Mark Fitzgerald — who took the role in October 2025 ...

Rodatherm Energy: The Refrigerant Gambit

By: Robert Buluma   Rodatherm Energy has done something no other geothermal startup has attempted at commercial scale: swapped water for refrigerant in a closed-loop system. The claim is 50% higher thermal efficiency than water-based binary cycles, achieved by circulating a proprietary phase-change fluid through a fully cased, pressurized wellbore. The company emerged from stealth in September 2025 with a $38 million Series A—the largest first venture raise in geothermal history. Lead investor Evok Innovations was joined by Toyota Ventures, TDK Ventures, and the Grantham Foundation. The engineering thesis is elegant. The execution risks are significant. This is an Alphaxioms examination of both. II. The Thermodynamic Distinction Every geothermal company you've covered moves heat using water or steam. Rodatherm moves heat using a fluid that boils and condenses inside the wellbore. In a conventional closed-loop water system (Eavor's model), water circulates as a single-phase liq...

GEN Electric Grid Impact Study RFP in Framingham Massachusetts Advances Utility Geothermal Networks

GEN Electric Grid Impact Study RFP Signals a Defining Moment for Geothermal Energy Networks in the United States By: Robert Buluma The United States geothermal sector is entering a new phase, one where geothermal systems are no longer being viewed only as sources of heating and cooling, but increasingly as strategic infrastructure capable of strengthening the electric grid itself. In one of the most important emerging developments in utility-scale thermal network deployment, the Home Energy Efficiency Team (HEET), in partnership with Eversource Gas, has officially launched a Request for Proposals (RFP) for a groundbreaking Electric Grid Impact Study focused on Geothermal Energy Networks (GENs), also referred to as Thermal Energy Networks (TENs). Backed by funding from the U.S. Department of Energy under grant “DE-EE0010662.0002 Home Energy Efficiency Team Utility-Managed Geothermal Pilot in Framingham, Massachusetts,” the initiative represents far more than a local energy pilot. It is...

Fervo Energy Is Sitting on a Lithium Goldmine: Why DLE + IPO Is the Billion-Dollar Move They Haven't Made Yet

Fervo Energy has raised $1.5B, slashed drilling costs, and is eyeing an IPO. But ignoring DLE lithium co-production leaves billions on the table. Here's why By Alphaxioms | Energy & Critical Minerals Analysis Image: Fervo Energy’s Nasdaq debut marks a defining moment for geothermal energy. ⚡🌍 Fervo Energy has become the undisputed poster child of next-generation geothermal. With over $1.5 billion raised, drilling times slashed, and high-profile power deals with Google and California utilities, they've proven that enhanced geothermal systems (EGS) can work at scale  But Fervo is leaving money in the ground. Literally. Every day, Fervo pumps millions of gallons of hot, pressurized brine through deep underground fractures at Cape Station (Utah) and Project Red (Nevada). They extract the heat, generate clean electricity, and then reinject the fluid. Job done. Except that brine isn't just water. Across the Great Basin — where Fervo operates — geothermal brines carry d...
