Verifying Green Hydrogen Emissions for CBAM
For South African green hydrogen producers to benefit from the CBAM advantage of low embedded emissions, they must be able to demonstrate — through verified certification — that their hydrogen has the claimed low carbon footprint. Without verification, the EU default emission value of 10.9 tCO₂/t applies.
The Verification Requirement
Article 4 of Regulation (EU) 2023/956 requires that embedded emissions be calculated using either:
- Actual verified emissions — calculated and verified according to the methodology in Implementing Regulation (EU) 2023/1773
- EU default values — published by the European Commission for each product category
For green hydrogen, the actual emissions approach is strongly preferable, as actual emissions (0.5–1.5 tCO₂/t) are dramatically lower than the default (10.9 tCO₂/t).
The EU RFNBO Standard
The EU's Delegated Regulation on Renewable Fuels of Non-Biological Origin (RFNBO) defines what counts as "renewable hydrogen" for EU purposes. Key requirements:
- Additionality: The renewable electricity used for electrolysis must come from new renewable capacity (not existing renewable generation)
- Temporal correlation: The renewable electricity must be produced in the same hour as the electrolysis (or within the same month in some cases)
- Geographic correlation: The renewable electricity must be produced in the same bidding zone or adjacent zone as the electrolysis
- Greenhouse gas threshold: The hydrogen must have lifecycle emissions below 3.38 kgCO₂e/kgH₂ (3.38 tCO₂/t H₂)
South African green hydrogen projects must comply with these requirements to qualify as RFNBO hydrogen for EU markets.
Accredited Verifiers for Green Hydrogen
Third-party verification of green hydrogen emissions must be conducted by accredited verifiers. In South Africa, relevant verifiers include:
- Bureau Veritas — ISO 14064-3 accredited, experience with renewable energy projects
- SGS South Africa — experience with energy and emissions verification
- DNV South Africa — experience with hydrogen and offshore projects
- TÜV Rheinland South Africa — experience with renewable energy certification
International verifiers with SA presence:
- CertifHy — EU-based green hydrogen certification scheme
- IRENA's Green Hydrogen Certification — international standard
The Certification Process
- Project design: Design the green hydrogen production system to meet RFNBO requirements
- Monitoring plan: Implement metering and monitoring systems for electricity consumption, electrolyser efficiency, and emissions
- Data collection: Collect production data over the certification period
- Third-party audit: Commission an accredited verifier to audit the data and production process
- Certificate issuance: Receive a certificate of compliance with the RFNBO standard
- CBAM declaration: Provide the certificate to the EU importer for their CBAM declaration
The Cost of Certification
Certification costs for green hydrogen projects are typically:
- Initial certification: R500,000–R2,000,000 (depending on project scale)
- Annual renewal: R200,000–R500,000
These costs are modest relative to the CBAM savings from verified low emissions:
- At 10,000 t H₂/year exported to EU: CBAM saving = (10.9 - 1.0) × €65 × 10,000 = €6.435 million/year
- Certification cost:
R1,000,000/year (€50,000/year)
- Net saving: €6.385 million/year
