For the Hydrogen Sector CBAM Solution
Carbonaz supports all colors of hydrogen production. There is separate calculation logic for grey (SMR), blue (SMR + CCUS), green (renewable electrolysis) and other production methods. Renewable energy guarantee certificates can be uploaded to the system, and CN code 2804.10.00 is supported.
Hydrogen Production Methods
All Colors of Hydrogen
Separate calculation logic and a separate emission profile for grey, blue, green and other production methods.
Grey Hydrogen (SMR)
Production from natural gas via the Steam Methane Reforming method. Today it makes up 95% of world hydrogen production. It has the highest carbon footprint.
Blue Hydrogen (SMR + CCUS)
Combining grey hydrogen production with carbon capture systems. The CO₂ capture rate can reach 85-95%, and permanent storage is required.
Green Hydrogen (Electrolysis)
Production by water electrolysis from renewable electricity. Alkaline, PEM (Proton Exchange Membrane) or SOEC (Solid Oxide) electrolyzer types. A zero-carbon promise.
Yellow and Pink Hydrogen
Electrolysis production with grid electricity (yellow) or nuclear electricity (pink). The carbon footprint depends on the grid mix. For Türkiye, the grid emission factor is taken into account.
Calculation Accuracy
CBAM 2026 Benchmark Data Built In
The EU Commission's official hydrogen benchmark values are defined in the system. A reference of 5.089 tCO₂/ton is used for the SMR method.
| Product | Benchmark | Source |
|---|---|---|
| Hydrogen (SMR method) | 5.089 tCO₂/ton | CBAM 2026 Benchmark |

Sector-Specific Capabilities
Designed from Scratch for Hydrogen
Separate Calculation for SMR and Electrolysis Methods
Completely different emission calculation logic for grey hydrogen produced from natural gas reforming and green hydrogen produced by electrolysis. Hybrid production is also supported.
Green Hydrogen Scope 2 Exemption
For green hydrogen produced entirely from renewable electricity, Scope 2 emissions are recorded as zero. It requires a renewable source guarantee certificate.
Blue Hydrogen Carbon Capture Integration
The amount of CO₂ captured with carbon capture systems is entered into the system. The capture rate, storage location and permanence are verified. Net emission is calculated.
Natural Gas Feedstock Calculation
In the SMR process, natural gas is used both as fuel and as feedstock. The system tracks both uses separately and applies the correct emission factors.
Electrolyzer Type Selection (Alkaline / PEM / SOEC)
Separate efficiency parameters for Alkaline (common, cheap), PEM (high purity) and SOEC (high efficiency) electrolyzer types. Electricity consumption (kWh/kg H₂) is tracked.
Renewable Energy Guarantee Certificate
Renewable electricity purchase agreements and Türkiye renewable energy guarantee certificates can be uploaded to the system. The green hydrogen claim is documented.
CN Code 2804.10.00 Support
CN code 2804.10.00 for pure hydrogen is defined in the system. The relevant CN codes for hydrogen carriers (ammonia, methanol) are also supported.
Hourly Renewable Matching
The EU regulation requires hourly renewable electricity matching for green hydrogen. The system can track hourly production and consumption data.
Multi-Tier Supply Chain
Collect data at unlimited depth from your suppliers of natural gas, renewable electricity, demineralized water and catalysts.
Accurate Annual Mark-up Penalty Rate
+10% in 2026, +20% in 2027, +30% in 2028 and beyond are correctly coded. A future cost projection is made with year-based simulation.
Full CBAM Factor Transition 2026 → 2034
The 0.025 → 1.000 transition schedule is recorded in the system. The green transformation projection is critical for the hydrogen sector.
Native-Language Interface and Support
Your team works in their own language. The interface, terms, documentation and support are available in multiple languages.
CBAM Factor Phase-In Schedule
From 2026 to 2034: Cost Projection
The CBAM factor rises year over year, reaching a full 100% in 2034. Carbonaz supports every transition year and shows your future cost today with the mark-up simulator.
| Year | CBAM Factor | Meaning |
|---|---|---|
| 2026 | 0.025 | 2.5% of the gross cost is paid |
| 2027 | 0.050 | 5% |
| 2028 | 0.100 | 10% |
| 2029 | 0.225 | 22.5% |
| 2030 | 0.485 | 48.5% |
| 2031 | 0.610 | 61% |
| 2032 | 0.735 | 73.5% |
| 2033 | 0.860 | 86% |
| 2034 | 1.000 | 100% (full CBAM) |
