Your reliable partner on the road to
zero-carbon emissions

Over the last 20 years, ACS Steel Group has become a well-known actor of decarbonation. Its primary family business is the boiler making ACS, which is specialized in hydroelectricity and makes very technical unit parts and prototypes for diverse energy markets and R&D mainly. The new entity of the group, SteelHy, works together with its partners to design, industrialize, and integrate their storage and distribution systems of renewable energies (hydrogen station, skids, containerization solutions, etc.) and decarbonation solutions for the industry.


By investing in R&D and industry 4.0, SteelHy wants to become the French metal leader in the development of a competitive hydrogen and biogas chain of excellence in France and abroad.

Since February 2022, IDEC Group has become a strategic equity partner of SteelHy. This partnership reflects IDEC Group’s desire to support innovative companies and build a clever ecosystem for decarbonation and green energies to address its clients’ issues. This strategy is perfectly in line with the first commitment of ACS Steel Group: to reach the zero-carbon goal.

The road to renewable energies ?

It is necessary to achieve a successful energy transition

SteelHy sees biogas as indispensable instruments to succeed in the energy transition. They make the decarbonation of economic sectors such as industry or mobility possible, especially when electrification is not a realistic option.

Commercial deployment of production, storage and distribution technological solutions is essential to make these solutions competitive.

SteelHy takes part in building a French hydrogen and biogas chain of excellence to support its partners in the industrialization of their solutions.
