Global Hydrogen Certification: Three New Signals From the US and EU
ANSI launches US standards coordination, EAC frameworks emerge for low-carbon products, and certification convergence accelerates across four major markets.
Key Highlights
- ANSI launches Hydrogen Standards Coordination Initiative — Phase II (Spring 2026) addresses pre-standardisation research and regulatory framework development
- Absolute Climate introduces Environmental Attribute Certificates (EACs) for low-carbon products, providing a transferable proof-of-sustainability model applicable to hydrogen
- ISCC RFNBO certification expands to sustainable aviation fuel (SAF) — signal that multi-commodity certification under a single framework is accelerating
- India, EU, US, and Japan are each building certification infrastructure on divergent timelines, creating growing complexity for internationally-trading producers
The US Standardisation Signal
Until 2026, the US hydrogen market operated without a unified certification framework. Projects certified under different voluntary standards produced hydrogen that was difficult to compare, trade, or use as compliance credit across international agreements.
ANSI's Hydrogen Standards Coordination Initiative changes that trajectory:
- Phase I (current): Mapping the existing US hydrogen standards landscape — identifying gaps, duplications, and misalignments
- Phase II (Spring 2026): Pre-standardisation research, regulatory framework needs, and alignment with DOE's Clean Hydrogen Hubs programme
- Downstream effect: US voluntary standards will likely converge toward a federal certification baseline by 2027-2028
This matters for producers targeting multiple markets. When the US formalises its framework, internationally-traded hydrogen will face four distinct certification jurisdictions simultaneously: GHCI (India), RFNBO (EU), JCM (Japan), and the emerging US standard. The window to design multi-framework compliant production systems is narrowing.
Environmental Attribute Certificates: The New Proof-of-Origin Model
Absolute Climate (San Francisco) launched a certification framework for low-carbon products using Environmental Attribute Certificates (EACs) — enabling verified product-level climate benefits to be transferred independently of physical supply chains.
This model, initially applied to concrete, steel, and SAF, mirrors what the EU has built for renewable energy through Guarantees of Origin (GoOs). The key innovation:
"Proof of sustainability decoupled from physical commodity delivery — tradeable, stackable, and transferable across supply chains."
For hydrogen, EAC-equivalent infrastructure is already emerging:
- EU GoOs (issued by AIB member bodies) for RFNBO-certified hydrogen
- JCM credit certificates for Japan-bound international hydrogen
- India's GHCI certificates (facility-level, government-issued)
The EAC model signals that the certification layer is maturing beyond government compliance into a traded asset class — with implications for price discovery, financing structures, and offtake contract design.
ISCC's Cross-Commodity Expansion
ISCC recently issued pre-certification to Syzygy for RFNBO-compliant sustainable aviation fuel (SAF) production — the same scheme that certifies green hydrogen for EU export. This is a quiet but significant signal: ISCC is positioning as a multi-commodity RFNBO certifier, not a hydrogen-specific scheme.
As the RFNBO framework expands across hydrogen, ammonia, methanol, and SAF, certification bodies that operate across all four fuels will have structural advantages. Producers building hydrogen-to-derivatives plants (power-to-x) will need a single scheme that can certify the full value chain — not separate certifications for each output.
The Convergence Problem
The four major hydrogen certification markets are building their frameworks on divergent timelines:
| Market | Framework | Status |
|---|---|---|
| EU | RFNBO (RED III) + Low-Carbon (2025/2359) | In force |
| India | GHCI | Operational, RFNBO-misaligned |
| Japan | JCM | Mandatory from April 2026 |
| US | ANSI-coordinated (TBD) | Phase II Spring 2026 |
Convergence — where a certification in one jurisdiction is recognised in another — does not yet exist. Every producer targeting more than one market must independently satisfy each framework's documentation, additionality, and audit requirements.
HyGOAT Implications
The multi-framework reality is the structural challenge that makes integrated certification platforms necessary. Manual compliance management across four jurisdictions, each with different data requirements and audit cycles, is not operationally viable at the scale India's SIGHT programme represents.
The EAC model is directionally important: if hydrogen certificates become tradeable assets (not just compliance tick-boxes), the platform managing those certificates gains financial infrastructure value — not just regulatory compliance value.
