Guhlen II

Towards local helium production in Germany!

About Guhlen II

Bibliographic research and field measurements have shown a gas mix rich in nitrogen and helium in the Guhlen II area.

In June 2023, 45-8 ENERGY submitted an exploration license application to the regional mining authority, the LBGR. The license was granted in April 2025 for a period of five years. Located in the state of Brandenburg, southeast of Berlin, the exploration license covers an area of 641 km² and concerns helium resources.

The granting of this exploration license and the subsequent validation of the assumptions would enable the exploitation of helium and any associated gases.

Guhlen II project

Geological context of the Guhlen II license exploration area located in Germany

Bibliographic research and field measurements have been carried out in the past, demonstrating significant helium potential in the area known as “Guhlen II.” The license was granted to the company in April 2025 and covers an area of 641 km² in the state of Brandenburg, southeast of Berlin, Germany. The purpose of this exploration license is to further develop geological knowledge of the area and confirm its helium potential.

The exploration license has been accepted for a period of five years in order to acquire the data necessary to confirm the accumulation of a gas mix rich in helium.

Beyond the Guhlen II area, 45-8 ENERGY is convinced of the potential of this particular geological region, where high helium content has been widely reported in the past but has never led to significant production due to a lack of use at the time.

The exploration area

The Guhlen II exploration license covers an area of 641km² in Brandenburg, south-east of Berlin.

The requested perimeter is voluntarily large, in order to gain a comprehensive understanding of the geology of the area, and then to target high-potential zones more precisely as acquisitions are made.

The gases of the area

Helium

The gas mix in the Guhlen II area consists of a helium fraction combined with nitrogen and natural gas, which it is important to co-value in an intelligent and innovative way.

Helium is at the heart of our business, and its potential is important for Germany’s national sovereignty and the supply of helium in Western Europe.

Nitrogen

Guhlen II gas is composed mainly of nitrogen, the most abundant element in the earth’s atmosphere (around 78% of its composition).

Given the abundance of nitrogen in the air, its appeal is limited and its economic use unlikely. Its release into the atmosphere poses no risk to humans (inert, odorless, invisible) or the environment (it does not contribute to the greenhouse effect and is already present in high concentrations in the earth’s atmosphere).

Methan

The proportion of natural gas present in the gas mix discovered in the Guhlen II area is considered an opportunity for innovation.
In order to recover this fraction of gas, 45-8 ENERGY plans to produce low-carbon, locally sourced hydrogen using several technological approaches:

  • through steam reforming with recovery and/or sequestration of the carbon dioxide emitted in the process (mineralization or reinjection into its original reservoir underground)
  • through pyrolysis/plasmolysis, enabling the production of hydrogen and carbon black.

The work program

The work program will be carried out in such a way as to reconcile industrial activity with respect for the environment and local residents, thanks in part to innovative technologies and methodologies developed and tested on our French projects, as well as by drastically reducing the footprint of our activity.

A local and strategic project

In addition to Guhlen II, the 45-8 ENERGY project represents a means of securing the local supply of helium for an entire region of Germany, which is currently in high demand and subject to recurring risks of shortages.

The Guhlen II production project is part of the company’s drive to value the most of all the resources present in the subsurface. 45-8 ENERGY has already established a commercial plan to secure outlets for each resource, namely helium, hydrogen and carbon dioxide.

Helium

Opportunities for helium

Germany uses 9.5 millions m³ of helium each year, making it the world's 5th largest consumer, and is also largely dependent on imports. Silicon Saxony, which covers Dresden and the surrounding area, is the largest microelectronics site in Europe and the 5th largest in the world.

This type of industry requires large volumes of helium to operate. Electronics accounts for 25% of the world's use of helium. Since the Guhlen project is located 100km from Dresden and, more specifically from the Silicon Saxony, the helium produced will be distributed directly to microelectronics companies in this major competitive cluster. In addition, INTEL is planning to build two semiconductor production facilities in Magdeburg, located 230km away from the project, by the end of the decade.

Part of our helium production could thus be dedicated to supplying these units, which consume large amount of helium and are essential to meet the needs of the New Tech.

Hydrogen

Opportunities for hydrogen

The eastern part of Germany is an important industrial region with many major consumers of hydrogen (green mobility, steel industry, chemical industry).

As part of the energy and ecological transition, projects using hydrogen are multiplying and the consumption of this resource should double by 2030, from 55 TWh (in 2020) to 110 TWh (in 2023). The hydrogen produced from the methane fraction of the Guhlen project will therefore contribute to the decarbonation of local industries, in search of a secure and more eco-responsible supply.

For example, part of the hydrogen from the Guhlen project could be sent to the ArcelorMittal steel plant, located 50km away, which is planning to produce eco-responsible steel, powered by hydrogen.

Carbon dioxide

Opportunities for carbon dioxide

Germany is both the largest producer and the largest consumer of industrial carbon dioxide in Western Europe.

However, the production of the resource is mostly concentrated in the West of Germany. And carbon dioxide from the eastern part of Germany is mainly generated by the seasonal production of ammonia.

Carbon dioxide produced on the Guhlen project will thus ensure a local, reliable and secure supply to numerous consumer companies in the region. These companies are very diversified and involve the carbonated beverage indutry (beer, soft drinks, water...), the chemical industry and the cryogenic industry.
