CBAM Sector Brief · Hydrogen
CBAM compliance for hydrogen importers
Every kilogram of imported hydrogen is in CBAM scope — there is no 50-tonne de minimis. Carbon Border generates your NCA Authorised CBAM Declarant pack, captures producer-verified electrolyser or SMR emissions, and procures CBAM certificates against your verified ledger.
Who needs CBAM authorisation for hydrogen?
Any EU-established importer of hydrogen (CN 2804 10) for any purpose — refining, ammonia, methanol, e-fuels, mobility, glass, or chemicals. The 50-tonne threshold does NOT apply: a single kilogram triggers reporting and authorisation requirements.
How embedded emissions are calculated
Hydrogen embedded emissions vary by an order of magnitude. Grey (SMR without CCS) ≈ 10 tCO₂/tH₂. Blue (SMR + CCS) ≈ 1-3 tCO₂/tH₂. Green (renewable electrolysis, RFNBO-compliant) ≈ ~0 tCO₂/tH₂. Verified producer data is essential — without it, the EU grey-hydrogen default plus 10% markup applies.
In 2026, the EU default value carries a +10% markup when the importer cannot present verifier-signed supplier emissions. Verified data nearly always lowers your CBAM certificate liability — Carbon Border collects it for you via secure supplier portals.
Common HS / CN codes in this sector
Top origin countries currently subject to CBAM filings for this category include Saudi Arabia, United Arab Emirates, Norway, United States, Australia.
UK CBAM (from 2027)
Hydrogen is in scope of UK CBAM from 2027. Verified renewable (RFNBO) and low-carbon hydrogen produced abroad benefits significantly from Carbon Border's supplier data flow into both EU and UK declarations.
What Carbon Border does for hydrogen importers
- Generates the full NCA Application Pack (Operational Capacity, Financial Exposure, HS-Code Alignment)
- Logs every shipment against the live ETS price and your verified emissions data
- Sends secure supplier portals so mills, smelters and producers upload signed emissions data
- Procures the right number of CBAM certificates each quarter via Stripe
- Maintains the 5-year audit trail required by Article 30 of Reg. (EU) 2023/956
- Mirrors the same workflow for the UK CBAM going live in 2027
Frequently asked questions
Why does hydrogen have no de minimis threshold?
Article 2(3) of Reg. (EU) 2023/956 explicitly excludes hydrogen and electricity from the 50-tonne threshold. The Commission considered hydrogen a strategically important early-deployment input where leakage risk justifies full coverage from kilogram one.
Does CBAM apply to hydrogen carriers like ammonia or LOHC?
Imported ammonia is regulated under the fertiliser sector (CN 2814) — but the embedded emissions are calculated from the underlying hydrogen feedstock route. LOHCs (liquid organic hydrogen carriers) and methanol used as hydrogen carriers fall under chapter 29.
How is renewable (RFNBO) hydrogen treated?
RFNBO-compliant hydrogen produced under the EU Delegated Act on renewable hydrogen, with a verifier-signed CertifHy (or equivalent) certificate, is treated as having zero direct embedded emissions for CBAM purposes.
What about blue hydrogen with CCS?
Verified CO₂ captured and permanently stored is deducted from embedded emissions. The producer must hold a third-party MRV report for the capture rate and the storage operator's certificate of permanent geological storage.
Is gaseous hydrogen treated differently from liquid?
No — CBAM applies per kilogram of H₂ regardless of physical state. Liquefaction energy is included in embedded emissions where it is performed by the producer.
