Automating Compliance for a Seamless Certification Process
Rotterdam, Netherlands – May 27, 2025 – Atmen and CertifHy today announced a strategic partnership, signed during last week's World Hydrogen Summit in Rotterdam, which names Atmen as the first officially recognised Compliance Technology Provider (CTP) for the CertifHy EU RFNBO Voluntary Scheme. This collaboration seeks to establish a streamlined digital infrastructure for producers to operationalize, document, and demonstrate compliance efficiently.
Atmen’s compliance platform simplifies and digitizes the certification process, ensuring economic operators can efficiently meet regulatory requirements. By integrating live compliance modeling, document generation, and emissions tracking, the platform eliminates complexity and allows operators to focus on production while staying aligned with evolving regulations. As a designated CTP, Atmen ensures full compatibility with the CertifHy EU RFNBO Voluntary Scheme, making compliance more transparent and accessible.
CertifHy, founded in 2014, is a frontrunner in the certification of renewable hydrogen and e-fuels. It operates schemes like the EU RFNBO Voluntary Scheme to help economic operators demonstrate compliance with the EU’s strict sustainability rules regarding the origin of renewable electricity. By formally recognising Atmen as a CTP, CertifHy enables a more efficient certification pathway that eliminates bottlenecks and improves communication between economic operators, certification bodies, and regulators.
“Operators will see major bottlenecks disappear,” said Flore de Durfort, CEO and Co-Founder of Atmen. “With this partnership, we create a clear communication chain and a trusted source of interpretation. Atmen and CertifHy share a vision of bringing certification into a more user- and system-friendly practice.”
Atmen’s platform is designed for neutrality, ensuring seamless integration across multiple certification schemes. While its recognition as a CTP by CertifHy underscores its alignment with EU RFNBO requirements, its broader interoperability potential offers economic operators a unified system for managing compliance across evolving sustainability frameworks.
The collaboration is already in motion, addressing key compliance questions such as carbon input validation, virtual PPA eligibility, and downstream emissions reporting. Atmen and CertifHy will continue refining the integration of certification processes into the Atmen platform, ensuring alignment with future regulatory updates and industry needs.
“Recognising Atmen as a CTP allows us to streamline how market participants interact with our scheme,” said Matthieu Boisson, Managing Director at CertifHy. “Digital infrastructure is essential for scaling certification without sacrificing rigour, and this partnership gives us both speed and consistency.”
About CertifHy: Founded in 2014, CertifHy is a frontrunner in the realm of renewable hydrogen and e-fuels’ certification, providing a comprehensive suite of tools to empower stakeholders engaged in the energy transition. It operates two schemes — the CertifHy EU Renewable Fuels of Non-Biological Origin (RFNBO) Voluntary Scheme and the CertifHy Non-Governmental Certificate (NGC) Scheme — which aim to verify the sustainability and origin of renewable and low-carbon hydrogen and its derivatives. CertifHy also offers precertification, which familiarizes companies with the data collection and documentation processes required for official certification, and an in-house e-learning platform — CertifHy Academy — to equip Economic Operators and Certification Bodies with the expertise needed to navigate the complex landscape of hydrogen certification. It fosters collaboration through its Stakeholder Platform, which invites representatives of the industry, government, and academia to shape the future development of hydrogen certification systems. Together, CertifHy’s robust certification schemes and knowledge-building resources pave the way for a cleaner energy future.
About Atmen: Atmen (atmen.co) is a regulatory technology company providing the data infrastructure that powers trusted certification of industrial products. Atmen focuses on automating certification and enabling large-scale, verifiable supply chain transparency across energy-intensive industries.

Headquartered in Munich, the company's platform is deployed across industrial sites in 9 countries, automating certification workflows and enabling verifiable proof of product attributes throughout the supply chain.

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.

About Atmen
Atmen (atmen.co) is a regulatory technology company providing the data infrastructure that powers the trusted certification of industrial products. Atmen focuses on automating certification and enabling large-scale, verifiable supply chain transparency across energy-intensive industries.
Founded in January 2023 by energy and regulation experts Flore de Durfort, Quentin Cangelosi, and Erika Degoute, Atmen has raised €6.3M to date to build technology that certifies industrial goods, starting with clean fuels.

At Atmen, we build the data infrastructure that enables certification of clean industrial supply chains. That means working with some of the most sensitive information our customers hold: real operational data. A recurring question we hear is simple but crucial — “If we entrust you with this data, how do we know it’s secure?”
Today, we can give a clear and independent answer. Atmen has achieved ISO 27001 certification, the globally recognized standard for information security management.
ISO27001 is the benchmark for how companies manage, protect, and audit data. It requires a systematic approach to information security across people, processes, and technology. Earning this certification is proof that Atmen meets international best practices for confidentiality, integrity, and availability of information.

ISO27001 is assurance that compliance automation at scale does not come at the expense of security. For our customers, it means:
Certification is not a one-off milestone. ISO27001 requires ongoing governance and annual audits by independent assessors. For Atmen, it’s part of a broader commitment: embedding security into every layer of our technology and operations as we scale.
This achievement reinforces Atmen’s mission to enable secure, scalable certification across Europe’s clean energy supply chains. Security and scalability don’t have to be in conflict — and ISO27001 is proof.
