Plum Acquisition Corp. IV and  Controlled Thermal Resources Outline a Large-Scale Geothermal and Critical Minerals Platform Plum Acquisition Corp. IV (“Plum IV”) and Controlled Thermal Resources Holdings Inc. (“CTR”) are moving toward a proposed business combination that would create a public company focused on one of the most ambitious geothermal and critical minerals developments in the United States. The combined entity is expected to trade on Nasdaq under the pro forma ticker CTRH, reflecting a platform built around clean baseload power, lithium recovery, and broader critical minerals production. The investor presentation dated August 2026 frames the transaction around CTR’s Hell’s Kitchen project in Imperial County, California, which is presented as a strategically positioned resource opportunity with energy, minerals, infrastructure, and permitting advantages.   At the center of the presentation is a clear message: this is not just a power project, and it is not j...

Deep Drilling Preparation for Geothermal Energy: The Erdwärme Breisgau Project The Erdwärme Breisgau geothermal project has received approval for its next phase, allowing Badenova and Herrenknecht to begin preparing a deep-drilling site near Hartheim in Baden-Württemberg, Germany. The partners plan to invest approximately €60 million to explore a geothermal reservoir located around 3,200 metres underground and develop a heating plant for regional district heating.  Why Deep Drilling Matters for Geothermal Heating Deep geothermal energy can provide a stable, renewable source of heat for district-heating networks. Unlike solar and wind power, which depend on weather conditions, geothermal heating can operate continuously when the underground reservoir and surface infrastructure are technically and economically viable. The Erdwärme Breisgau project is designed to investigate a hot-water reservoir beneath the Hartheim area. The plan involves drilling two directional wells: one producti...

Sage Geosystems Places SMECI Facility in Service, Validating a Scalable EGS Model Sage Geosystems has moved a step closer to proving that enhanced geothermal systems can be engineered for repeatable, commercial performance. The company announced that its SMECI facility in South Texas has been placed in service, and the results from more than 120 days of operating data are being presented as a validation point for its proprietary EGS approach. For a sector that has long struggled with subsurface unpredictability, water losses, and limited scalability, that is a meaningful milestone. What makes this announcement stand out is not simply that the facility is operating, but what Sage says the operating campaign demonstrated. The company says the project produced consistent reservoir behavior, low water losses, and performance that matched its predictive modeling. In geothermal development, those are the kinds of results that can move a project from promising to financeable. If the claim...

AFK Geothermie launches second dublette drilling in Aschheim , pathway to 1,200 geothermal heat connections Summary AFK Geothermie has begun preparing the drill site for a second deep geothermal dublette near Aschheim. Drilling is scheduled to start in November at depths up to 2,600 meters. The project aims to supply up to 1,200 residential connections in Aschheim, Feldkirchen and Kirchheim with district heating from January 2028, expanding an established field first tapped in 2008. Total investment is around €65 million, combining public grants, municipal contributions, company equity and long-term loans. Why this matters now The AFK project is a practical example of how municipal-scale geothermal systems move from demonstration to scale-up. As European policymakers push for decarbonized heating, replicable, well-financed geothermal projects that integrate with existing district heating networks are becoming critical. The Aschheim dublette highlights common technical, financial and ...

Cornish Lithium Secures £7.2 Million UK Government Funding for Cross Lanes Geothermal Lithium Project Cornish Lithium has secured £7.2 million in UK Government grant funding to advance its Cross Lanes Geothermal Lithium Project in Cornwall. The funding will support a £14.5 million programme of drilling, testing and technology demonstration designed to assess whether lithium can be produced commercially from naturally occurring geothermal waters. The project represents an important development for the UK’s critical minerals strategy. It combines geothermal energy, direct lithium extraction and domestic mineral production in a single development model. If successful, Cross Lanes could contribute to the UK’s ambition to establish a secure, lower-carbon supply of lithium for electric vehicle batteries, energy storage systems and other advanced manufacturing applications. The grant will also enable Cornish Lithium to undertake further appraisal drilling at Baldhu, near Truro. Together, th...
