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.

What this means

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.

Why it matters for our customers

ISO27001 is assurance that compliance automation at scale does not come at the expense of security. For our customers, it means:

• Confidence that production data is handled under the highest security standards
• Trust that Atmen’s platform scales without compromising data integrity
• Evidence for auditors and regulators that information security is independently verified
  
  

Our commitment

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.

Looking ahead

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.

Germany’s first RFNBO-certified e-methane facility is now live in Werlte. The Atlantis site, operated by Hy2gen, has become one of the very first industrial plants worldwide to achieve certification under the CertifHy scheme. 

Behind the scenes, Atmen’s compliance automation platform provided the digital backbone that made certification possible. Together, Hy2gen, CertifHy, and Atmen proved that renewable molecules can be tracked and certified at an industrial scale under Europe’s strict rules.

A Milestone for Germany

In May 2025, Hy2gen’s Atlantis facility in Werlte became the first site in Germany to be certified under the EU’s RFNBO scheme for e-methane. 

“I’m proud we are now officially among the first sites worldwide to produce hydrogen and methane molecules with RFNBO certification here in Werlte,” said Matthias Lisson, Country Director at Hy2gen.

“In basic terms, the RFNBO certification proves that every molecule of renewable hydrogen or renewable methane produced here in Werlte can be precisely tracked for its carbon footprint emitted throughout the entire lifecycle.”

Proving the System Works

RFNBO certification is a stress test for data management and carbon accounting in alignment with operational supply chains. Success depends on the entire ecosystem: producers, certifiers, auditors, and the right technology.

“I am really proud to share this milestone for CertifHy, for Atmen, for Hy2gen, and also for the entire renewable hydrogen and e-fuels industry,” said Matthieu Boisson, Managing Director at CertifHy.

“The Hy2gen Werlte site is one of the very first industrial facilities worldwide to be certified under the CertifHy EU RFNBO scheme.”

The Role of Technology

Atmen’s Automate platform turned regulatory complexity into operational reality. It transformed more than 70,000 data points into audit-ready documentation, automated the issuance of Proof of Sustainability, and delivered a secure, up-to-date GHG calculator. By digitizing the process, Atmen helped cut preparation time by up to two months.

“Atmen’s role is to connect the dots in the space of certification,” said Flore de Durfort, Co-Founder and CEO of Atmen.

“We do two things. First, we bring clarity: we bridge the gaps between schemes, the rules of the game, and the reality of a very concrete supply chain. Second, we accelerate: we provide pre-built automated workflows for data ingestion, traceability, and verification.”

For Hy2gen, the impact was clear. “Without your tool, we wouldn’t have survived the audit,” said Christian Zuber. “Without Atmen, it would be double the work. We saved two months of full-time effort thanks to Automate.”

From Ambition to Execution

The Werlte milestone proves that RFNBO certification at an industrial scale is possible when producers, certifiers, and technology providers work together.

“Certification of a product is always teamwork,” said Lisson.

“In this case, it was crucial to have Atmen provide the database and the software, reducing the time spent on all the documentation work within the certification scheme. Together, we succeeded as a team, with CertifHy providing the scheme.”

The lesson is clear: compliance can scale when built into operations, not bolted on. Standardization accelerates trust. Digital tooling reduces friction across the value chain.

“This is what building energy resilience looks like,” Lisson concluded. By achieving Germany’s first RFNBO e-methane certification, Hy2gen has helped move the sector from ambition to execution. With the right tools and partners, more producers are now in a position to follow.
