Not yet regulated: The taxation of hydrogen combustion

Technical differentiation problems at filling stations

At hydrogen filling stations, it is currently not possible to make a technical distinction between fuel cell and combustion vehicles. This leads to uncertainties under tax law, as both vehicle types are taxed differently. In some cases, filling station operators react by banning hydrogen burners from filling stations, but this is not a sustainable solution.

Solutions and regulatory conflicts

Discussed solutions such as selection options at the fuel terminal or separate fuel cards meet with concerns from the main customs office regarding tax fraud or contradict the EU’s AFIR Directive, which requires non-discriminatory ad hoc payments. The implementation of the AFIR Directive collides with national tax law requirements.

Future prospects

Legal clarification is urgently needed to address the discrepancies between EU requirements and national tax laws. Potential solutions include:

  1. Technological innovations for automatic vehicle identification
  2. Harmonization of tax laws for hydrogen as a fuel
  3. Development of a uniform European legal framework
    Overcoming these challenges is crucial for the future of hydrogen mobility and requires close cooperation between legislators, industry and research.

Current contributions

Berlin, 10 February 2026 | The Clean Energy Partnership (CEP), an expert committee for hydrogen mobility, welcomes two new members: Poppe + Potthoff and Tyczka Hydrogen. As an independent, technology-neutral organisation, the CEP brings together players from all areas of hydrogen mobility in road, rail and factory transport. After a six-month trial period, both companies are now contributing their specific expertise to the CEP's working groups as full members.
Berlin, 01.12.2025 |The Clean Energy Partnership (CEP) expert committee is ensuring the continuity of its successful work with a newly elected Board of Directors. With Florian Brandau, Ignacio Garcia-Lorenzana and Frank Fronzke, the board will in future combine even more expertise in infrastructure development and the ramp-up of hydrogen-powered commercial vehicles and passenger cars. As an established registered association, the CEP is thus strengthening its commitment to hydrogen mobility in Germany and Europe - with a clear focus on the development and implementation of international standards and framework conditions.
