Summary

CertaLink Energy Certification is a digital certification system developed by Siemens Energy together with TÜV SÜD and the German Energy Agency (dena). The platform uses blockchain-based technology to verify the origin, carbon intensity, and sustainability attributes of products such as renewable electricity, green hydrogen, e-fuels, and other low-carbon commodities. It is designed to support traceability and automated certification across complex energy supply chains.

Overview

The CertaLink energy certification was developed in response to growing demand for verifiable sustainability claims in renewable energy and low-carbon fuels markets. As hydrogen, synthetic fuels, and other Power-to-X products become more widely traded, companies increasingly require systems capable of tracking renewable electricity inputs, emissions data, and chain-of-custody information across multiple production stages. The platform focuses on products such as green hydrogen, e-methanol, e-ammonia, renewable electricity, and synthetic fuels, particularly in markets shaped by regulations including the EU Renewable Energy Directive (RED II) and requirements for renewable fuels of non-biological origin (RFNBOs).

CertaLink combines operational production data with distributed ledger technology to create tamper-resistant sustainability records. Administered by Dena, Siemens Energy, and TÜV SÜD, the system is intended to automate certificate generation, improve traceability, reduce administrative burdens, and help reduce risks of double counting or greenwashing. The platform works together with independent certification bodies and is designed to integrate with existing sustainability and verification frameworks used in renewable fuels and clean energy markets.

Companies seeking certification must connect operational and measurement data from production facilities to the CertaLink certification platform. This may involve integration with industrial control systems, smart meters, or other digital monitoring infrastructure.

The certification process includes third-party verification by accredited certification bodies. Sustainability criteria and emissions accounting requirements depend on the certification scheme being applied, including schemes aligned with RED II requirements for renewable fuels of non-biological origin (RFNBOs).

The platform is designed to automatically generate sustainability certificates once production data and compliance conditions are verified. Information tracked may include:

  • electricity sourcing,

  • production inputs,

  • carbon intensity,

  • process emissions,

  • and chain-of-custody data.

The system also aims to reduce risks of double counting and greenwashing through continuous digital traceability and controlled access to certification data.

Current Status

CertaLink is currently operational and has been used in pilot and demonstration projects involving green hydrogen and e-fuels production. Siemens Energy and dena have highlighted projects including Nobian’s chlor-alkali electrolysis plant in Germany and the Haru Oni e-fuels project in Chile. The platform continues to expand alongside growing demand for traceable low-carbon products and compliance with emerging hydrogen and sustainable fuels regulations, particularly within the European Union.
