Hy-way to Helium

45-8 ENERGY, the first company dedicated to the eco-friendly exploration and production in Europe of helium and its associated resources.

Our innovative approach aims to develop jointly and locally these resources as well as those that can be associated, to act for the ecological transition.

Founded in 2017, 45-8 ENERGY is a French company based in France (Metz and Lyon).

A European leader in the exploration and production of eco-friendly industrial gases such as helium and natural hydrogen, 45-8 ENERGY is expanding in Europe. Currently operator of two helium exploration licenses in France, the company continues its expansion in Germany with two new exploration license applications currently under review. The Guhlen II and BRIMIR projects are for the helium resource and resources that can be associated with it.

An answer to a real need

Helium and hydrogen are two strategic resources, essential to many industries. 

Aware of the crucial issues involved in their supply, the founding partners wanted to put their solid experience in subsurface exploration at the service of 45-8 ENERGY in order to act concretely and sustainably in favour of the ecological transition and to commit to this new and unique exploration in Europe.

Multiple research projects

Helium exploration together with other associated resources is a real innovation with its own problematics. For this reason, 45-8 ENERGY is also conducting Research and Development projects with academic and industrial partners in order to develop effective and adapted technology to efficiently and reliably detect these resources in the near surface.

A company committed to the environment

At a time when 100% of helium consumed in Western Europe is imported at high energy costs and carbon footprint, 45-8 ENERGY aims to develop an eco-friendly local helium supply chain which could therefore significantly reduce the environmental impact of such industry.

Helium and natural hydrogen at the heart of our activities


Our goal: responding, on an eco-reponsible way, to a tense market where demand is growing, particularly in a context where there are recurring shortages and where Western Europe is 100% dependent on sourcing helium from abroad from overseas markets.


Our activity is dedicated to native hydrogen, i.e. hydrogen created naturally by our planet, usually in combination with helium. Native, or natural, hydrogen provides an additional solution to the low carbon hydrogen mix.
