Nantes (France) and Munich (Germany), 20 January 2025, 7:30 AM: Lhyfe (Euronext: LHYFE), a pioneering producer and supplier of green and renewable hydrogen 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 hydrogen and Power-to-X (PtX) sectors.
Lhyfe, on the Path to RFNBO* Certification
Since its creation, Lhyfe has strived to meet the highest ecological standards for its hydrogen. It had been eagerly awaiting the approval by the European Commission of the first “RFNBO” (Renewable Fuel of Non-Biological Origin) certification schemes for renewable hydrogen. Following their publication in December 2024, Lhyfe has begun the necessary steps to obtain RFNBO certification for its production.
* The RFNBO certification confirms that hydrogen is produced sustainably (via water electrolysis) and from 100% renewable electricity. It includes a comprehensive carbon footprint assessment of this production process. The certification ensures compliance with the strict criteria defined by the European Union and adherence to the highest environmental standards, thereby strengthening trust among partners, clients, and investors.
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 hydrogen can now be accompanied by a Digital Product Passport—an innovation that provides a complete and precise description of the carbon footprint of the hydrogen produced, including detailed information:
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 hydrogen 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 hydrogen, equipping clients with the tools needed to align with their emission and decarbonisation goals transparently.
By combining Lhyfe’s expertise in renewable hydrogen production and Atmen’s advanced automation software, this partnership simplifies compliance with strict sustainability regulations such as RFNBO.
“Atmen is thrilled to partner with Lhyfe, one of the most innovative and fastest-growing hydrogen producers in Europe,” said Flore de Durfort, CEO of Atmen. “Together, we are setting a new standard in traceability, enabling the hydrogen sector to meet the strictest sustainability requirements with precision and transparency.”
“Our collaboration with Atmen is a major step in realising our commitment to transparency for our clients, both in terms of sustainability and traceability,” commented Antoine Hamon, Chief Operations Officer at Lhyfe. “With Digital Product Passports, we are enhancing trust in the sustainability of our hydrogen. We invite the sector to align with this practice, which will help develop the industry with the same spirit of trust.”
Lhyfe is a European group devoted to energy transition, and a producer and supplier of green and renewable hydrogen. Its production sites and portfolio of projects seek to provide access to green and renewable hydrogen in industrial quantities, and enable the creation of a virtuous energy model capable of decarbonising entire sectors of industry and transport.
In 2021, Lhyfe inaugurated the first industrial-scale green hydrogen production plant in the world to be interconnected with a wind farm. In 2022, it inaugurated the first offshore green hydrogen production pilot platform in the world.
In 2023, it inaugurated two new sites, and currently has several sites under construction or expansion across Europe.
Lhyfe is represented in 12 European countries and had 200 staff at the end of June 2024. The company is listed on the Euronext market in Paris (ISIN: FR0014009YQ1 – LHYFE). Lhyfe.com

A new EU-funded project (SURFER) will support Europe’s energy transition by creating more resilient, decarbonised energy systems by advancing hydrogen electrolysers. Atmen joins the consortium to demonstrate how flexible electrolysers can support the penetration of renewables on the power grid.
Variable renewable energy sources (VRES), such as solar and wind, have become the cheapest energy sources available. However, the intermittent nature of VRES presents significant energy storage issues, and this has limited their deployment. At the same time, the production of green hydrogen from electrolysers is projected to represent a significant fraction of the energy usage in Europe’s future, decarbonised energy system. As electrolysers are very quick to start and stop, hydrogen can function as an energy buffer for renewable energy.
The Clean Hydrogen Joint Undertaking’s project SURFER (Supporting Uptake of Renewables with Flexible Electrolysers for Resilient energy systems) aims to facilitate the widespread deployment of variable renewable energy sources by demonstrating the use of flexible electrolysers as dynamic energy buffers. It also aims to stabilise multiple types of energy networks, focusing primarily on power grids, but also considering heat valorisation and isolated or weak grids.
SURFER brings research and industry partners like Atmen together to demonstrate, in real operating environments, how flexible electrolysers can support the stability of the power grid. This capability is essential for scaling both renewable power and renewable hydrogen in Europe.
The project brings together research institutions, industrial operators, grid actors, and digital compliance experts, including Atmen, to study and demonstrate how flexible electrolysers can be integrated into the power grid.
“SURFER addresses two of Europe’s key energy challenges at once: reducing the cost of green hydrogen and enabling higher adoption of renewables”, says project coordinator at SINTEF, Dr. Federico Zenith.
“High shares of renewable electricity introduce volatility and new constraints for power systems,” says Quentin Cangelosi, Co-founder of Atmen. “SURFER brings research and industry partners like Atmen together to demonstrate, in real operating environments, how flexible electrolysers can support the stability of the power grid. This capability is essential for scaling both renewable power and renewable hydrogen in Europe.”
SURFER's multi-disciplinary consortium consists of leading research institutions, hydrogen producers, grid operators, equipment manufacturers, and safety and certification experts. Together they will address the complexities of electrolyser dynamics and energy system integration, significantly advancing beyond the state-of-the-art.
The main goal of the project is to enable electrolysis plants to make additional revenues from power grid stabilisation, also making the latter more resilient and decarbonised with increased VRES adoption and maximisation of their use. The project will improve energy security and drive down costs, thanks to additional sources of revenues and heat integration, thus supporting Europe's energy transition goals.
Through multiple demonstrations across diverse European sites, including operational environments in France, Germany, and Norway, the project will improve the integration of these electrolyser technologies into the energy system. The partners will be the first in the world to provide grid services with electrolysis plants on a commercial basis.
The project will demonstrate the capabilities of Proton-Exchange Membrane ELectrolyser (PEMEL), Alkaline Electrolyser (AEL) and Solid Oxide ELectrolyser (SOEL) to rapidly modulate their operation to accommodate variations in renewable energy supply, grid demand and waste heat when available. The partners have made available their already existing, large-scale sites, rated up to 10 MW for PEMEL, 1.5 MW for AEL and 300 kW for SOEL.
Munich – 30. October, 2025 – Siemens and Atmen have signed a Global Strategic Partnership Agreement (GSPA) to jointly promote interoperable digital and compliance solutions for green hydrogen and Power-to-X (PtX) projects.
The partnership combines Siemens’ digital capabilities with Atmen’s regulatory automation platform to jointly promote solutions that support compliant power-to-X supply chain development. By aligning digital plant design with certification requirements from the start, the two companies aim to help developers accelerate readiness for evolving schemes and standards, such as those included in the EU Renewable Energy Directive.
“Atmen’s modules could now integrate seamlessly with Siemens’ digital twin and control tower technologies, turning scattered data into a continuous flow,” said Flore de Durfort, CEO of Atmen.
“Siemens’ tools assist companies in building and operating smart supply chains and testing scenarios. Paired with Atmen’s certification platform, engineers and procurement teams get the info needed to stay compliant, resilient, and ensure products meet standards.”
The agreement establishes a structured collaboration between the two companies. Siemens and Atmen seek to coordinate on a shared pipeline of opportunities, align early in tenders and strategic projects, and participate jointly in selected trade fairs and customer engagements.
A bi-annual steering committee, led by senior managers from both companies, aims to review market trends and collaboration opportunities. A dedicated working group then facilitates coordination on ongoing business development and portfolio alignment.
“Our partnership aspires for innovation, credibility, traceability and sustainability from design through operation,” said Peter Ammann, Head of Center of Competence for Siemens’ Hydrogen business.
“Siemens’ and Atmen’s strengths combined pave the way for green hydrogen’s end-to-end value chain becoming a cornerstone of a decarbonized global energy system.”
The partnership is non-exclusive and does not involve technology integration at this stage. Instead, both companies will continue to develop their respective platforms independently, while enabling interoperability in customer projects of mutual interest and involvement.
Together, Siemens and Atmen aim to significantly reduce project risk, lower the levelized cost of hydrogen (LCOH), and enhance trust in the traceability and sustainability of hydrogen and PtX projects across Europe and beyond.
