Lhyfe, a pioneering producer and supplier of green and renewable H₂ for industry and mobility, and Atmen, an integrated compliance automation platform, have decided to collaborate to set a new standard of excellence in carbon footprint traceability and transparency within the H₂ and Power-to-X (PtX) sectors.

Advancing transparency with the H₂ digital passport. With a commitment to maximum transparency and its rapid expansion in multiple European countries, Lhyfe sought to exceed current regulations even before obtaining its RFNBO certification. Thanks to its partnership with Atmen, Lhyfe now has a robust traceability system with unprecedented precision and granularity.

Each delivery of Lhyfe's green H₂ can now be accompanied by a Digital Product Passport—an innovation that provides a complete and precise description of the carbon footprint of the H₂ produced, including detailed information:

• Energy sourcing: where, when, and how the electricity used in the production process was generated
• Embedded emissions: step-by-step breakdown of the carbon intensity calculations
• Supply chain contribution: the impact of each processing and logistics stage on the H₂'s carbon footprint.

This collaboration starts with the production unit in Bouin (Vendée, France) and will be extended to other Lhyfe sites. The company has also initiated steps to obtain RFNBO certification for H₂ produced at its various sites. Once achieved, the digital passports will include the “RFNBO-compliant” label.

This partnership delivers unparalleled traceability and compliance for Lhyfe’s green H₂, equipping clients with the tools needed to align with their emission and decarbonization goals transparently.

Simplifying compliance with regulations like RFNBO. By combining Lhyfe’s expertise in renewable H₂ production and Atmen’s advanced automation software, this partnership simplifies compliance with strict sustainability regulations such as RFNBO.

• Precision in reporting: High-accuracy carbon intensity calculations ensure full transparency.
• Compliance automation: Automatically generated Digital Product Passports reduce human intervention for improved efficiency.
• Granular client alignment: Producers can meet their clients’ emission and decarbonization targets with unprecedented detail.

Flore de Durfort, CEO of Atmen said, “Atmen is thrilled to partner with Lhyfe, one of the most innovative and fastest-growing H₂ producers in Europe. Together, we are setting a new standard in traceability, enabling the H₂ sector to meet the strictest sustainability requirements with precision and transparency.”

Antoine Hamon, Chief Operations Officer at Lhyfe said, “Our collaboration with Atmen is a major step in realizing our commitment to transparency for our clients, both in terms of sustainability and traceability. With Digital Product Passports, we are enhancing trust in the sustainability of our H₂. We invite the sector to align with this practice, which will help develop the industry with the same spirit of trust.”
