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

On June 23, 2025 and July 10, 2025, two events of the transformation hub cH2ance will focus on hydrogen mobility.The cH2ance webinar on June 23, 2025, 14:30-16:00 is dedicated to the topic of “Fleet operation in the context of economic efficiency and regulation”.On July 10, 2025, cH2ance invites you to the 5th innovation round from 09:00 to 14:30 in Münster to experience the potential of hydrogen mobility live.
The Federal Ministry of Finance's current draft budget increases the chances of promoting alternative drive systems - especially hydrogen - to a greater extent. This is crucial in order to make technologies competitive and achieve climate targets.
