MEP Bert-Jan Ruissen (ECR) has asked the European Commission whether it has evidence that compliant biofuel blends cause structural engine damage in inland shipping, and whether it plans to standardise fuel blending for the sector. The question, tabled on 1 July 2026, follows warnings from the Dutch inland shipping association ASV that widely used biofuels, particularly FAME, are causing technical problems such as damage to fuel pumps and injectors. Ruissen also cited a boatmaster who suspects that fuels containing animal fats harm engines.
The MEP's query targets the practical impact of blending mandates under the Fuel Quality Directive and RED III, which have led to the introduction of bio-components in inland navigation fuel in several countries. While some in the sector dismiss the concerns as unfounded, Ruissen's question seeks to clarify whether the Commission has data on real-world engine damage from compliant fuels. He also presses for harmonised fuel standards for inland shipping, akin to those for road transport, to address potential inconsistencies in blending practices. The Commission is expected to reply within approximately six weeks; its answer will signal whether it sees a need for regulatory action or technical guidance to address the sector's concerns.
