Concept for a hydrogen plant that produces green hydrogen using renewable energy

CertifHy EU RFNBO certification: Your key to EU markets for renewable hydrogen.

The EU targets to achieve climate neutrality by 2050 and the RED II / III requirements make certified hydrogen a prerequisite for market access in Europe. If you and your organization want to produce, import or use renewable hydrogen in the EU, you must meet strict criteria.

TÜV Rheinland is one of the first recognized certification bodies to offer the CertifHy EU RFNBO certification, an internationally recognized solution for sustainable hydrogen certification. Benefit from our testing expertise to gain access to EU market mechanisms and meet regulatory requirements in a fast-changing environment.

What is the CertifHy EU RFNBO certification?

CertifHy is a European certification system for sustainably produced hydrogen and e-fuels. It assesses so-called Renewable Fuels of Non-Biological Origin (RFNBOs), fuels that come exclusively from renewable, non-biological energy sources such as wind, solar energy, or hydropower. The best-known example is green hydrogen, which is produced by electrolysis using renewable electricity.

The term RFNBO comes from the EU's Renewable Energy Directive 2018/2001 (RED II). RFNBO certification based on the CertifHy standard is the prerequisite for the issue of proofs of sustainability (POS) and therefore crucial for the participation in EU market mechanisms under RED II / RED III.

Why you need an RFNBO certification:

RFNBO certification is mandatory for all organizations wanting to trade, produce or use hydrogen in accordance with RED II / III in the EU, because only certified RFNBOs:

  1. are eligible to be issued Proofs of Sustainability (POS), the official proof of the product's origin and sustainability.

  2. allow the participation in EU market mechanisms, such as trading with greenhouse gas reduction quotas (GHG quotas).

  3. meet the formal requirements set by authorities, regulatory agencies, and incentive programs.

  4. measurably contribute to meeting the EU's renewable energy targets, particularly in the industrial and mobility sectors.

  5. secure competitive advantages thanks to a transparent, standard-compliant, and traceable production.

Key requirements for a CertifHy EU RFNBO certification.

For hydrogen to be certified as an RFNBO, strict technical and regulatory requirements must be met, which focus on a sustainable production by electrolysis using electricity from renewable, non-biological sources such as wind, solar energy or hydropower. In addition, the EU Directive specifies key criteria:

Show all Hide all

Additionality

The electricity used must come from newly established, additional plants. The aim is to actively promote the expansion of renewable energy.

Temporal correlation

The generation of renewable electricity and the operation of the electrolyzer must be timed to coordinate with each other.

Geographical correlation

Energy source and electrolyzer must be spatially linked in a way that ensures a physical traceability of the proof of origin.

Greenhouse gas emissions

A CO₂ reduction of at least 70% compared to fossil fuels must be achieved (target value: ≤ 28.2 g CO₂eq/MJ with a reference value of 94 g CO₂eq/MJ).

Recognized certification body

Only recognized certification bodies – such as TÜV Rheinland – may issue a valid CertifHy EU RFNBO certificate.

TÜV Rheinland is your recognized testing body for CertifHy EU RFNBO.

TÜV Rheinland is one of the first recognized certification bodies to offer CertifHy EU RFNBO certification. Certification is performed as part of a recognized voluntary certification scheme based on the CertifHy RFNBO scheme documents, and it is a prerequisite for obtaining Proofs of Sustainability (POS) and for accessing EU funding mechanisms according to RED II / RED III.

We offer both certification and an upstream pre-certification (design stage). The latter involves the collaboration between the operator (e.g. the hydrogen producer), an external consultant (e.g. Hinicio or LBST) and the certification body (TÜV Rheinland) even before the plant goes into operation. The initial certification is performed in line with the commissioning of the plant, followed by ex-post certification six months later. Thereafter, a re-certification is required at least annually.

We support you throughout the entire certification process:

Pre-Certification (Design Stage)

Risk protection in the planning phase: TÜV Rheinland and designated external consultants review whether the plant is certifiable.

Initial Certification

When the plant is commissioned, TÜV Rheinland conducts an on-site audit. Upon a positive audit result, we issue the CertifHy EU RFNBO certificate.

Ex-Post Certification

Six months later, a re-certification is conducted based on actual operating data.

Regular Re-Certification

Re-certification is required at least annually to maintain certification validity and to remain in regulatory compliance.

Your benefits at a glance:

Access to EU funding mechanisms
Verifiable sustainability
Strengthen your market position
Comprehensive support

Only a valid RFNBO certification enables you to benefit from incentives such as the GHG quota and to unlock regulatory advantages.

The certification confirms compliance with all RED II / III criteria via an independent, internationally recognized sustainability certificate.

A valid CertifHy EU RFNBO certificate creates trust among customers, partners and investors and provides a significant competitive advantage.

From the initial concept to the final re-certification: As an experienced and recognized testing body, TÜV Rheinland supports you throughout the entire process.

CertifHy or H2.21 – Which standard is right for your market?

What is CertifHy?

CertifHy is a European certification system for hydrogen, ammonia and e-fuels. It ensures RED II / III compliance and is the basis for issuing Proofs of Sustainability (POS). The CertifHy EU RFNBO certification system thus plays a key role in promoting the use of renewable fuels of non-biological origin.

What are RFNBOs?

RFNBO is short for “Renewable Fuels of Non-Biological Origin”. They are produced exclusively from renewable energy sources such as wind, solar energy, or hydropower without the use of biomass. The best-known example is green hydrogen, produced by electrolysis using renewable electricity. But e-fuels fall into this category as well. The term RFNBO comes from the EU Renewable Energy Directive (RED II / RED III) and is central to the regulation of sustainable energy sources in Europe.

What is the difference between RFNBO, green hydrogen and low-carbon hydrogen?

RFNBOs meet the specific RED II / III requirements regarding e.g. additionality, temporal and geographical correlation and a CO₂ reduction of at least 70%. Green hydrogen generally refers to hydrogen from renewable sources, without necessarily meeting all RFNBO criteria. Low-carbon hydrogen, by contrast, also includes other production processes that contribute to CO₂ reduction such as CCS or pyrolysis.

What is the validity of a CertifHy EU RFNBO certificate?

After the initial certification, an ex-post certification must be conducted six months later. Thereafter, a re-certification is required at least annually to maintain validity.

For whom is the certification particularly relevant?

For operators of electrolyzers, producers of e-fuels, project developers, investors and all companies wanting to produce, import, or market hydrogen in the EU.

Who is authorized to carry out the RFNBO certification?

Certification may only be carried out by bodies recognised under the EU's voluntary certification scheme. TÜV Rheinland is one of the first recognized testing bodies and therefore authorized to issue a valid RFNBO certificate.
