The H2Accelerate collaboration has recently emphasized the critical need for policy support to establish a European hydrogen trucking ecosystem in line with the European Commission's ambitious CO2 reduction targets for heavy-duty vehicles by 2030. The targets emphasize the essential role of zero-emission trucks, including those powered by hydrogen technology, to significantly reduce greenhouse gas emissions. While the Commission has taken positive steps through directives like the Renewable Energy Directive and funding schemes, stakeholders highlight the existing uncertainty around the long-term business case, which hinders large-scale investments necessary for a sustainable transition. The collaborative effort advocates for joint funding of hydrogen refuelling stations and trucks, coordinated infrastructure planning, certainty in renewable hydrogen availability, and measures to enhance cost competitiveness with diesel trucks. These actions are seen as vital to pave the way for scaled deployment of hydrogen trucks and supporting infrastructure, essential for achieving emissions reductions and climate neutrality targets. The H2Accelerate collaboration stresses the urgency of implementing these measures to build a reliable and competitive hydrogen trucking ecosystem. By transparently working with policymakers, the collaboration aims to create the necessary conditions for accelerated innovation and infrastructure development in the hydrogen fuelled trucking sector, ultimately contributing to a sustainable and low-emission transport future.
