Abstract

In order to achieve zero net emissions to limit the effects of climate change, a key sector that need decarbonising is transport. One idea is to use hydrogen-powered technologies. For example, Coexpair, a company specialised in composite materials, is interested in developing hydrogen tanks made of composite materials for the automotive and aeronautical sectors. To develop such a tank, it is important to have an idea of the certification process to be followed. It is essential to know the regulatory framework for the certification of hydrogen tanks. The lack of knowledge of the regulatory framework and the difficulty in navigating the regulations, codes and standards (RCS) is a significant barrier to market entry and the development of tank supply chains. Thus, in order to gain knowledge of the regulatory framework that applies to gaseous and liquid hydrogen tanks, a study on the certification process was performed. This study starts with the compilation of the different RCS that apply to both types of tanks. It continues with the compilation of the compliance and risk matrices for both tanks. The study then outlines the development plan for each tank and the associated development schedule. It concludes with the budget forecast estimates for developing the full-size gaseous and liquid hydrogen tanks to an approved prototype design. This report also proposes a general tank approval process for Type 5 hydrogen containers for the automotive sector and liquid hydrogen containers for the aeronautical sector.
