Regulation (EC) No. 79/2009 Regulating the Principles for Type Approval of Hydrogen-Powered Motor Vehicles

Regulation 79/2009 published by the European Parliament and the Council regulates the principles for the type approval of hydrogen powered motor vehicles. This regulation also includes amendments to the directive 2007/46/EC, which establishes a framework for the approval of motor vehicles and their trailers and systems, components and separate technical units designed for such vehicles.

This regulation applies to:

• Hydrogen powered vehicles of categories M and N as defined in Annex IIA to directive 2007/46/EC, including impact protection and electrical safety of such vehicles
• Hydrogen components designed for motor vehicles of categories M and N as defined in Annex I
• Hydrogen systems designed for motor vehicles of categories M and N, including new forms of hydrogen storage or use

Manufacturers must demonstrate that all new hydrogen powered vehicles sold, registered or put into service in the European Union countries and all hydrogen components or hydrogen systems have type approval in accordance with this regulation. It must also provide approval bodies with appropriate information on vehicle characteristics and test conditions.

The test procedures for type approval of hydrogen containers designed to use liquid hydrogen are:

• Burst test: The purpose of this test is to provide evidence that the hydrogen container has not failed before a certain high pressure level has been exceeded, the explosion pressure being exceeded. To obtain type approval, the value of the actual burst pressure during the test must exceed the required minimum burst pressure.
• Bonfire test: The purpose of this test is to provide evidence that the container with the fire protection system did not explode when tested under specified fire conditions.
• Maximum fill level test: The purpose of this test is to prove that the system that prevents overfilling of the container is working adequately and that the hydrogen level during the filling process never causes the pressure relief devices to open.
• Pressure test: The purpose of this test is to provide evidence that the hydrogen container can withstand a certain high pressure.
• Leak test: The purpose of this test is to provide evidence that the hydrogen container shows no evidence of leakage under certain conditions.
