Germany’s Daldrup & Söhne AG has been awarded a contract to drill a pair of deep geothermal wells near Munich, in the south of the country.

In a statement, the company reported that the contract, worth €16.8mn (US$19.6mn), was awarded by Amperland Thermalwärme GmbH (ATW), a subsidiary of the joint municipal waste management company, based in Olching, northwest of Munich.

The drilling technology and geothermal energy specialist will now sink deflected deep geothermal wells with drilling lengths of around 2,430m and 3,300m on the site of the Geiselbullach cogeneration plant.

Work on the construction of the site is scheduled to begin in September this year, with actual drilling expected to be carried out from December 2025 to May 2026.

“It is impressive to see the determination with which the cities and municipalities around Munich are pushing ahead with the heat transition for their citizens,” said Andreas Tönies, CEO of Daldrup & Söhne AG.

ATW has received a grant of €8.8mn (US$10.3mn) for the financial implementation of the geothermal project, with the funds originating from the federal government’s Effective Heating Networks (BEW) programme.

The Daldrup & Söhne AG statement added that the project will enable the further expansion of the district heating network of the Olching municipal utility company and, for the first time in Germany, combine thermal waste utilisation with geothermal energy to expand the district heating supply in the region in a climate-neutral manner.

“This is a significant step for regional energy supply with fuel-independent heat,” added Tönies.

“The geological layers in the molass basin are now very well known and suitable for using deep thermal water to extract heat in a cycle system for local and district heating networks. We are already in talks with other potential municipal and private sector clients.”

TGS, a global leader in energy data and subsurface intelligence, has unveiled a new series of Basin Insight Reports designed to support operators, analysts, and investors in navigating North America’s rapidly evolving energy landscape—estimated to be worth over US$2tn.

These reports combine rich geological data with production trends and economic performance, offering a holistic perspective on basin development dynamics.

Built on TGS' extensive multi-client library, the reports integrate geological, geophysical, and well data to provide in-depth analysis that goes far beyond surface-level observations. The result is a data-driven tool that helps energy professionals better understand what’s driving performance in specific basins—blending insights from the subsurface with real-time production metrics, drilling costs, and operator strategies.

The first in the series explores the differences between the established Legacy Haynesville and the up-and-coming Western Haynesville—often referred to as “Waynesville”—which includes Robertson, Limestone, Freestone, and Leon counties in Texas. This analysis highlights the competitive nature of Waynesville’s well performance and its untapped growth potential, especially when compared with the more mature Legacy Haynesville. One key element that stands out in the Western region is the infrastructure challenge, particularly regarding midstream capabilities required to fully exploit the high-pressure, deep gas reservoirs found there.

David Hajovsky, EVP of Multi-Client at TGS , said,“What we're seeing in the Western Haynesville is a play rapidly approaching Legacy economics, but the infrastructure bottleneck means timing is everything". He also added, "Our Basin Insights Reports provide the integrated view needed to navigate both the geological potential and the logistical realities."

The Basin Insight Reports are structured to support continuous learning and evaluation across various regions. Each edition will focus on a specific basin and provide actionable intelligence to identify high-value drilling opportunities and guide capital allocation. Where available, the reports will be further enhanced by TGS’ vast onshore seismic data, offering greater subsurface clarity and supporting more accurate forecasting.

As TGS expands its onshore seismic acquisition across key basins, the insights offered through these reports are set to grow deeper and more precise, adding even more value for stakeholders across the energy ecosystem. These reports are designed not just for operators and investors, but also for media, analysts, and market commentators looking for reliable, in-depth understanding of changing basin dynamics.

With Basin Insight Reports, TGS positions itself as a critical partner in the energy transition—delivering the kind of integrated, intelligent analysis required to make informed decisions in a fast-moving, high-stakes environment.

Geothermal energy is becoming increasingly important for Bulgaria’s energy future.

Expanding the use of geothermal power can reduce and potentially replace fossil fuels, especially when combined with other renewable sources. This shift will help Bulgaria build a modern, sustainable economy while creating jobs and developing skills that could position the country as a European leader in renewable technologies. It also supports Bulgaria’s long-term goal of reaching carbon neutrality by 2050.

The Bulgarian government has set an ambitious target to develop 400 MW of geothermal energy capacity by 2026, reflecting geothermal energy’s vital role in the nation’s transition to a low-carbon economy. Unlike other renewables, geothermal energy provides reliable, clean, and affordable base-load power without needing costly battery storage. Currently, over 80% of Bulgaria’s base-load power comes from fossil fuels and nuclear energy, so geothermal offers a valuable alternative that can reduce this dependency.

Geothermal energy comes from heat stored inside the Earth. Deep geothermal heat originates from radioactive decay and friction inside the Earth, causing underground temperatures to rise with depth, reaching thousands of degrees near the core. When hot rocks underground contain water, wells can bring that heat to the surface for various uses. Shallow geothermal heat, on the other hand, comes from the sun and is stored near the surface, maintaining a constant 10-15°C temperature just below ground.

In Bulgaria, underground temperatures increase by about 25°C to over 40°C per kilometre, meaning parts of the country could have geothermal sources hotter than 150°C at depths of 4,000 to 6,000 metres. These temperatures make it possible to use geothermal energy for heating greenhouses, fisheries, spas, district heating, industrial processes, and even electricity generation. Shallow geothermal heat, typically below 25°C, can be harnessed with geothermal heat pumps for efficient heating and cooling of buildings, saving up to 80% on energy costs compared to traditional systems.

Bulgaria’s geothermal potential varies across two main geological regions divided by the Stara Planina Mountains. The northern region has a large sedimentary basin with proven medium to high temperature resources, thanks to historic oil and gas exploration. The southern region consists of smaller basins and mountains, with geothermal potential suggested by numerous thermal springs, although deeper resources remain less explored.

Despite Bulgaria’s rich geothermal resources, development has been slow, mainly due to regulatory challenges. Over the past 30 years, geothermal use has grown by only 16%, and there are currently no geothermal power plants. Updating regulations to align with international best practices is key to attracting investment and unlocking Bulgaria’s geothermal potential quickly.

The Bulgarian Association Geothermal Energy is working to unite government, industry, and experts to support geothermal development. The government’s roadmap includes policy reforms, scientific studies, and pilot projects to demonstrate economic viability and encourage investment. Transitioning expertise from the oil and gas sector to geothermal development will also create jobs and new skills.

The path to a sustainable energy future in Bulgaria depends on collaboration and commitment to making geothermal energy an everyday reality. As the Bulgarian Association Geothermal Energy notes, “The journey will require significant manpower and specialist expertise,” but it offers a clear opportunity to build a cleaner, greener economy.

Enhanced geothermal energy is poised to power the future of Artificial Intelligence (AI), according to a new white paper by Fervo Energy.

AI requires huge amounts of energy, but is advancing faster than the power grid can support, which poses one of the central dilemmas to its ongoing roll-out.

Leading voices in the field now acknowledge that AI’s growth will be limited by the availability of reliable energy, the white paper notes.

In a 2025 Senate hearing, OpenAI CEO Sam Altman noted that “the cost of AI will converge to the cost of energy… the abundance of [AI] will be limited by the abundance of energy.”

According to Fervo Energy, the timing is becoming urgent.

Even conservative projections show electricity demand from data centres growing faster than new power generation can come online.

While some developers have turned to nuclear and natural gas to supply data centres with needed firm power — such as Microsoft’s restart of the Three Mile Island nuclear facility or ExxonMobil’s plans for new gas plants — those options face limits in availability, long timelines and supply chain constraints.

“The speed and scale of Enhanced Geothermal Systems (EGS) make the technology uniquely positioned to power data centres before 2030,” Fervo Energy notes.

The white paper goes on to outline the advantages of why EGS is a reliable, clean and scalable solution that can meet the gigawatt-scale power needs of modern data centres.

They include:

Economies of scale: Bigger data centre clusters require bigger power plants, offering a fit with EGS because cost per megawatt declines as project size increases.

Abundant resources: Reports from the National Renewable Energy Laboratory and the US Geological Survey identify hundreds of gigawatts of untapped EGS resource potential across the country.

Speed to market: Standardised, modular plant designs make it possible to complete projects in as little as 18 months.

Utah stands out as the optimal starting point for the first enhanced geothermal-powered data centre cluster, the company adds.

“The state has high geothermal resource potential, supportive permitting policies, and strong community and commercial engagement. Utah already hosts gigawatts of data centre capacity and is one of the fastest-growing tech hubs in the US.”

It is also home to the Department of Energy’s FORGE research site, three operational geothermal plants, and the site of Fervo Energy’s Cape Station, the largest EGS development in the world.

“By pairing EGS development with the rapid growth of data infrastructure, regions like Utah are positioned to deliver the reliable, clean, and domestic energy supply needed to support continued AI leadership,” Fervo Energy adds.

A new digital, interactive map documenting Germany’s geothermal energy potential, and possible locations, has been released.

The resource was developed through the WärmeGut research project under the direction of the LIAG Institute for Applied Geophysics (LIAG) in Hanover, with the Georg-August-University Göttingen (UGOE) and the company, geoENERGIE Konzept GmbH from Freiberg, in collaboration with all 16 geological state services.

It is now freely available in the Geothermal Information System GeotIS.

The project’s manager, Prof. Dr. Inga Moeck, hailed it as a “historic milestone” for geothermal research in Germany.

"Together with the project partners and the state geological services, we have succeeded in developing a digital map that meets both the individual requirements of the respective federal states and an easy-to-understand standardisation of the complex data situation.”

The Federal Ministry for Economic Affairs and Energy (BMWE) provided funding the project.

The map is based on a traffic light system with ‘green’ showing regions where geothermal probes can be used without restriction, yellow indicating limited usage opportunities, and red highlighting areas that are not eligible for use.

This simple system is intended to offer both specialist companies and private homeowners and municipalities a quick entry into geothermal energy and an uncomplicated orientation as to whether geothermal use is possible by means of probes or not.

The researchers expect the interactive map to grow interest in geothermal across the country and to help municipalities, cities and even households understand potential use cases and opportunties.

“Without geothermal energy, the [energy] transition cannot succeed,” said Moeck.

“We expect that this map will draw attention to geothermal energy as a measure in municipal heating planning and give a decisive boost to both the energy transition and scientific geothermal research.”
