## Questions

### What is the CBAM cost per tonne of hydrogen in 2026?

About €104.65 per tonne at default values on the Grey (SMR, Natural Gas) route (9 tCO2 per tonne plus the default-value mark-up), with 98% of the EU benchmark still allocated free.

### How much does the production route change the CBAM cost?

By 2034 the default-value cost ranges from €53.51 per tonne on the Green (Electrolysis) route to €963.14 per tonne for the most carbon-intensive route listed.

### How can an exporter lower this cost?

Replace default values with verified actual emissions from the installation: CBAM charges on the embedded emissions declared, and for this sector default values carry a 30% mark-up from 2028.
