Innargi and H. Anger’s Söhne Forge Long-Term Partnership to Power Geothermal Growth in Denmark and Germany

INNARGI and H. Anger’s Söhne Seal a Groundbreaking Geothermal Drilling Deal for Denmark and Germany

In a major stride toward Europe’s clean energy ambitions, Innargi A/S, a leading Danish geothermal developer, has entered into a three-year framework agreement with H. Anger’s Söhne Bohr- und Brunnenbaugesellschaft mbH, one of the continent’s most experienced drilling companies. The deal covers the provision of drilling rig services for geothermal projects across Denmark and Germany, marking a significant advancement in the region’s pursuit of sustainable, low-carbon district heating.

Under the agreement, approximately 20 deep geothermal wells will be drilled over the next three years, each designed to supply renewable and stable heat to communities. These wells will utilize the City Rig 500, one of Europe’s quietest and most technologically advanced rigs — developed jointly by Anger and Herrenknecht Vertical. The City Rig 500’s design is tailored specifically for urban geothermal operations, allowing complex drilling tasks to be carried out in populated areas with minimal noise and disruption.

“This partnership allows us to advance geothermal energy, providing stable and renewable district heating to consumers in Denmark and Germany. Collaborating with a single supplier across various projects enables us to gain valuable insights that can further reduce costs in future initiatives,”

Samir Abboud, CEO of Innargi A/S.

For H. Anger’s Söhne, the partnership is not just a contract — it’s a strategic leap into the heart of Europe’s green transition.

“This contract gives us the chance to plan long-term and work effectively in geothermal energy with our skilled teams. We look forward to supporting the green transition in Denmark and Germany while collaborating closely with geothermal experts,”

Uwe Schindler, CEO of Anger

This collaboration embodies Europe’s growing commitment to decarbonize its heating sector, which remains one of the largest contributors to urban CO₂ emissions. By leveraging geothermal heat, Denmark and Germany are setting benchmarks for sustainable urban energy systems that combine technology, environmental responsibility, and economic efficiency.

Amsterdam Strikes Geothermal Gold: Hot, Thick, Permeable Reservoir Confirmed

Breakthrough Beneath the Beach: Amsterdam Region Hits Geothermal Paydirt at Strandeiland By: Robert Buluma The Netherlands just took a giant leap toward fossil-free heating. On the artificial island of Strandeiland (part of Amsterdam’s fast-growing IJburg district), the SCAN exploration well has officially confirmed what the geothermal community has been hoping for: a thick, hot, and , most importantly permeable reservoir in the Slochteren Formation. Key numbers that matter: Reservoir thickness: 152 meters Bottom-hole temperature: 66 °C Permeability: confirmed via successful production and injection tests That’s not screaming-hot by Icelandic standards, but for direct-use district heating in one of Europe’s densest urban areas, 66 °C is more than enough to supply thousands of homes with clean, baseload heat – forever. Why This Well Changes Everything for the Netherlands The Dutch government launched the SCAN program (Seismic Campaign Nethe...

Vulcan Energy's G-LEP Plant in Landau Paves the Way for Europe's Sustainable Lithium Revolution

Breaking Ground: Vulcan Energy's G-LEP Plant in Landau Paves the Way for Europe's Sustainable Lithium Revolution By: Robert Buluma In the heart of Germany's Rhineland-Palatinate region, a groundbreaking ceremony marked the laying of the foundation stone for the first optimized Geothermal and Lithium Extraction Plant (G-LEP) in Landau, spearheaded by Vulcan Energy Resources, an Australian-German company. As Petra Dick-Walther, State Secretary in the Ministry for Climate Protection, Environment, Energy, and Mobility of Rhineland-Palatinate, described in her recent social media post, this project represents a "quantum leap into the future." It enables the simultaneous extraction of climate-neutral lithium and generation of renewable energy from the hot thermal beds of the Upper Rhine Graben, opening new avenues for Germany's energy transition, supply security, and Europe's sovereignty over critical resources. Lithium, a key component in batteries for electri...

Zanskar’s Big Blind: First Blind Geothermal Discovery in 30 Years

Big Blind: The Geothermal Discovery That Changes Everything By: Robert Buluma Utah startup Zanskar Geothermal quietly dropped one of the most important announcements in American energy in decades. They discovered and confirmed “Big Blind” ,the first completely blind, commercial-grade geothermal system found in the United States in over thirty years. Let that sink in. No hot springs. No fumaroles. No steaming ground. No prior wells. Zero surface expression whatsoever. Just desert, sagebrush, and – 7,000 feet below, a reservoir hot enough and permeable enough to support gigawatt-scale power production. This isn’t incremental progress. This is a paradigm breaker. Why “Blind” Discoveries Matter So Much For the last 40 years, geothermal development in the U.S. has been geographically handcuffed. You could only build plants where nature advertised the resource on the surface – think Yellowstone, The Geysers, or Imperial Valley. Ever...

Geo Dipa's Game-Changing Leap: Commercial Silica and Lithium Production from Geothermal Brines by 2028

Geo Dipa's Ambitious Leap: Extracting Silica and Lithium from Geothermal Brines by 2028 Introduction In an era where the global energy transition demands sustainable sources of critical minerals, Indonesia's state-owned PT Geo Dipa Energi ( Persero ) is positioning itself at the forefront of innovation. By 2028, Geo Dipa plans to commence commercial production of silica and lithium extracted from geothermal brines, a byproduct of its geothermal power operations. This initiative not only diversifies the company's revenue streams but also aligns with Indonesia's broader goals of enhancing renewable energy capacity and supporting the electric vehicle (EV) battery supply chain. Geothermal energy, harnessed from the Earth's heat, produces hot brines rich in dissolved minerals like lithium and silica. Traditionally viewed as waste, these brines are now seen as valuable resources. Geo Dipa's strategy builds on years of feasibility studies and international partnershi...

FINANCING STRATEGIES FOR GEOTHERMAL PROJECTS LEVERAGING TAX CREDIT INCENTIVES

FINANCING STRATEGIES FOR GEOTHERMAL PROJECTS LEVERAGING TAX CREDIT INCENTIVES Aligning Policy, Risk Mitigation, and Investor Capital to Unlock Geothermal Growth Geothermal energy stands at a unique crossroads in the global energy transition. It is one of the few renewable resources capable of delivering continuous, baseload power and heat, independent of weather conditions. Unlike solar and wind, geothermal offers grid stability, industrial heat, and long-term energy security. Yet despite its immense potential, geothermal deployment has historically lagged behind other renewables due to high upfront capital costs, geological uncertainty, and complex financing requirements. In recent years, governments and financial institutions have increasingly turned to **tax credit incentives as a strategic lever to overcome these barriers. By reducing capital expenditure, improving cash flow profiles, and attracting institutional investors, tax credits are reshaping how geothermal projects are fina...

Geothermal-Powered Greenhouses: Qingyun County's Leap Toward Sustainable, Year-Round Agriculture in Shandong

Harnessing Geothermal Energy to Power Modern Agriculture: How Qingyun County Is Redefining Sustainable Food Production in Shandong By: Robert Bulum a As winter tightens its grip across northern China, most agricultural regions brace for declining productivity, rising energy costs, and increased environmental pressure. Yet in Qingyun County, located in China’s eastern Shandong Province, a different story is unfolding,one where geothermal energy is quietly transforming agriculture into a resilient, low-carbon, high-yield enterprise. At the heart of this transformation lies the Shandong Shuifa Aerospace Modern Agriculture Industrial Park, where geothermal energy has become a critical enabler of year-round food production, economic efficiency, and environmental sustainability. A Warm Oasis in the Depth of Winter Shortly after the Minor Snow solar term, temperatures outside the greenhouses in Qingyun County drop sharply.
