Bellona welcomes the opportunity to provide feedback on the methodology for assessing hydrogen and electrolyser candidate PCI/PMI projects within the TEN-E framework. Building on our previous contributions to this process on hydrogen infrastructure needs and the 1st Union List of Candidate Projects, we commend the Commission’s recognition of the role of hydrogen as a decarbonisation tool for hard-to-abate sectors where alternative decarbonisation pathways may not be feasible or economic and aspiration to assess candidate projects for a trans-European hydrogen infrastructure and electrolysers against that background.
