Objectives and problems to be solved: Provide inputs for regulatory activities on an EU and global level to facilitate harmonised pro-cedars for the approval of hydrogen fuelled road vehicles (with both internal combustion en-gene and fuel cell drive trains), hydrogen refuelling infrastructure and the relevant interfaces between the vehicle and the filling station. Ensure safe development, introduction and operation of hydrogen fuelled road vehicles and hydrogen filling stations throughout the EU and also on a global scale. By achieving the above objectives one of the commonly perceived barriers for the introduction of hydrogen-fuelled vehicles with maximum well-to-wheel energy efficiencies and minimum well-to-wheel emissions - i.e. the approval of vehicles for operation on public roads with pub-lily accessible infrastructure - shall be achieved. Description of work: Draft regulations for the approval of hydrogen fuelled road vehicles have been developed in EIHP (Contract JOE3-CT97-0088) and were submitted to the relevant European regulatory bodies and to UN-ECE WP.29 in spring 2001. These draft regulations are on its way to be de-eloped to such a level that they can be harmonised on a global level, initially between the EU and North America. By applying these draft regulations to the design and approval of road vehicles with direct onboard hydrogen storage they are validated by taking into account not only hydrogen related vehicle components and systems but also safety requirements, refuelling pro-cedars and periodic inspections. For the relevant hydrogen refuelling infrastructure components and systems, applicable national standards and regulations are to be identified and necessary requirements for new draft standards and possibly draft regulations for approval be developed. These activities among others comprise refuelling procedures, safety aspects, periodic inspections and the layout of refuelling stations. The interface between the refuelling station and the vehicle (receptacle and nozzle) are an important issue. To what extent certain elements of the refuelling systems are suitable for harmonisation on a global scale, e.g. components, is an issue for investigation. Comparative risk and safety analyses with respect to the release of hydrogen in confined and semi-confined environments, such as tunnels, garages, refuelling stations, and inner city streets are undertaken in order to provide data in sufficient depth enabling the partnership to define the required inputs for hydrogen related standards and regulations. Expected Results and Exploitation Plans:
- Development of a worldwide-harmonised regulation for hydrogen fuelled road vehicles.
- Development of procedures for periodic vehicle inspections (roadworthiness).
- As far as possible development of a worldwide standard or regulation and of periodic inspection procedures for the relevant refuelling infrastructure, subsystems or components. These draft regulations and standards will enable vehicle and infrastructure industry to save enormous resources in bringing hydrogen fuelled road vehicles into everyday use. Many count-tries will for the first time have the legal basis to approve the operation of hydrogen-fuelled vehicles on public roads and refilling at public refuelling stations. In addition, the access of European vehicle and infrastructure component manufacturers to the EU market as well as the North American market will be facilitated in the medium and long term.
