Atmen is proud to announce its latest achievement as the winner of the coveted H2-Age Award at this year’s National Hydrogen Economic Forum. This recognition underscores Atmen’s pivotal role in advancing the hydrogen industry through innovative solutions.
Sponsored by the National Hydrogen Economic Forum, the BMW Group, Hamburg Invest, and the Renewable Energy Hamburg Cluster (EEHH), the H2-Age Award celebrates trailblazing start-ups that propel the hydrogen sector forward. The award spotlights outstanding innovations across the entire hydrogen value chain, supporting young companies poised to make significant impacts.
Atmen was honoured at the 3rd National Hydrogen Economic Forum in Hamburg on May 7, 2024, where the team not only received a €5,000 prize but also a trophy and the title of "Best Hydrogen Start-up 2024". The event provided a platform for Atmen to showcase its products to a distinguished audience, including industry leaders and innovators.
The decision was made by a distinguished panel of judges, including Dr. Stefan Kaufmann, Member of the German Bundestag and former Federal Government Commissioner for Hydrogen Innovation; Prof. Dr. Christopher Hebling, Director of International Affairs at the Fraunhofer Institute for Solar Energy Systems ISE; and Jan Rispens, Managing Director of Erneuerbare Energien Hamburg Clusteragentur GmbH (EEHH).
In his laudatory speech, Jan Rispens particularly emphasized the platform's high degree of digitalization and the relevance of the green certification topic for the sector. Atmen provides the ideal interface between legal and regulatory requirements for green hydrogen certification, including for the requirements of the European Commission in accordance with the RED II Directive, and the operational data flows during production, supply and use of green hydrogen. It turns a complex, tedious topic into a set of highly usable applications, derisking hydrogen projects development and operations.
"We are at a turning point in the way the industry verifies its sustainability efforts. Hydrogen and e-fuels are a core part of the industrial decarbonization, but also the first energy-intensive products where the complexity of proving and certifying decarbonization are so acute." commented Flore de Durfort, co-founder and CEO of Atmen.
Atmen continues to push the boundaries of technology and innovation in the hydrogen industry, committed to contributing to a sustainable and energy-efficient future.

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.
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.


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.
