Discussion Points on HyTunnel CS Recommendation Report

The three-year HyTunnel CS project culminated in the report titled Deliverable D6.9, “Recommendations for inherently safer use of hydrogen vehicles in underground traffic systems.” The HyTunnel CS project aimed to perform pre-normative research for the safety of hydrogen-fueled vehicles traveling through tunnels or entering confined spaces. The main objective was to compare the relative risk of hydrogen vehicles entering underground traffic systems to existing fossil fuel-powered vehicles [1]. Upon reviewing the risk assessment and research reported in this document, along with the recommendations, the Hydrogen Safety Panel (HSP) has identified several issues that warrant further consideration. It is the strong opinion of the HSP that until these concerns are resolved, these recommendations should not be used as a basis for regulatory decisions concerning fuel cell electric vehicle access to tunnels or parking garages.
