45-8 Energy, the first company
dedicated to the eco-friendly exploration and production 
of helium and natural hydrogen in Europe.

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.

An answer to a real need

45-8 Energy is benefiting from the extensive experience acquired by its founding partners over more than ten years in various subsurface activities to focus on helium and natural hydrogen, strategic resources which are vital for many industries. Our will is to act sustainably in favour of the ecological transition.

Multiple Research projects

Helium and natural hydrogen exploration 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 it underground.

A company committed to the environment

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