Proposal for a

REGULATION OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL

on type-approval of hydrogen powered motor vehicles and amending Directive 2007/46/EC

(presented by the Commission){SEC(2007)1301}{SEC(2007)1302}

EXPLANATORY MEMORANDUM

1) CONTEXT OF THE PROPOSAL

Grounds for and objectives of the proposal

The objective of the proposal is to lay down harmonised rules on the construction of motor vehicles with a view to ensuring the functioning of the internal market while at the same time providing for a high level of public safety and a high level of environmental protection.

The proper functioning of the single market in the European Union requires common standards regarding the approval of hydrogen powered vehicles. Action at Community level prevents varying product standards emerging across Member States which results in fragmentation of the internal market and imposition of unnecessary barriers to intra-Community trade.

At the same time, since there are perceived safety issues with using hydrogen for vehicle propulsion, it should be ensured that hydrogen systems are as safe as conventional propulsion technologies.

General context

Hydrogen is not a source of energy but a promising energy carrier.

The use of hydrogen as fuel for road vehicles offers an environmentally friendly solution for mobility. This is because with the use of hydrogen as fuel, whether in fuel cells or internal combustion engines, there are no carbon emissions and greenhouse gases produced from the vehicle. If the fuel is produced in a sustainable manner, the use of this propulsion technology could significantly contribute to the improvement of the environment.

However, at present hydrogen powered vehicles are not included in the European Community vehicle type-approval framework. This situation results in a fragmented internal market of these vehicles, which discourages the introduction of this environmentally friendly technology.

Furthermore, hydrogen is a substance that has different characteristics from conventional fuels that are used for vehicle propulsion. In order to realise the environmental benefits associated with the use of hydrogen vehicles, the share of these in the total vehicle fleet should be increased. One of the major factors contributing to the increasing number of hydrogen vehicles on the roads is the existence of public confidence in this new technology.

Existing provisions in the area of the proposal

There are no existing provisions in the area of the proposal.

Consistency with the other policies and objectives of the Union

The proposal is fully in line with the aims of the European Union's Sustainable Development strategy and contributes significantly to the objectives of the Lisbon strategy.

2) CONSULTATION OF INTERESTED PARTIES AND IMPACT ASSESSMENT

Consultation of interested parties

Consultation methods, main sectors targeted and general profile of respondents

In developing the proposal the Commission has consulted stakeholders in a number of ways:

- There was consultation with the Hydrogen Working Group. This is a specialist expert stakeholder working group responsible for supporting the Commission on issues related to the type-approval of hydrogen vehicles. A broad range of interested parties is involved in the work of this group: national authorities, vehicle manufacturers, component suppliers and industry associations.

- A questionnaire was sent to stakeholders in June 2006 on possible policy options regarding the approval framework for hydrogen vehicles. The questionnaire aimed at gathering views of stakeholders as to the preferred option and the associated costs of approval under each of these options.

- A consultant was engaged to provide input for the impact assessment and to give technical advice on the draft proposal for a potential regulation.

- To understand more fully the implications of the policy options, the consultant organised meetings with key automotive companies involved in hydrogen technology to generate additional data on safety, technology and the related costs.

- There were presentations to key stakeholders of the Hydrogen Working Group during the second half of 2006 and early 2007 on the results of the work carried out by the consultant.

- The preliminary draft proposal for a Regulation on the type-approval of hydrogen vehicles was put to public consultation in July 2006. The consultation generated around 20 responses from a range of different stakeholders.

Summary of responses and how they have been taken into account

During the internet consultation, a number of issues were raised by stakeholders.[1] The impact assessment that accompanies this proposal provides a full account of the substantive issues raised and discusses how they have been taken into consideration.

Collection and use of expertise

Scientific/expertise domains concerned

The proposal required analysis of the necessary safety provisions and the assessment of the available policy options as well as the associated economic, societal and environmental impacts.

Methodology used

The following work was carried out by the consultant:

- review of relevant literature to identify safety and environmental issues surrounding the introduction of hydrogen vehicles;

- gathering and evaluation of information on the impacts of the various policy options on public safety, the environment and the economy;

- assessment of stakeholder responses to the questionnaire sent out by the Commission services in June 2006 on the available policy options;

- comparison of impacts of policy options regarding public safety, the environment and the economy in qualitative and quantitative terms;

- review of technical requirements of a draft proposal for a potential regulation as to its ability to address the identified safety issues.

Main organisations/experts consulted

Input for the impact assessment and technical advice on the draft proposal for a potential regulation was provided by TRL Ltd. in the UK.

Summary of advice received and used

The Commission used the consultant’s report as an input to the analysis of the various policy options. The preferred policy option has been selected on the basis of a cost-benefit analysis, as explained in the impact assessment accompanying the proposal.

Means used to make the expert advice publicly available

The report of TRL is available on the DG Enterprise and Industry web site.[2]

Impact assessment

Four policy options have been considered:

(1) No policy change: This option would involve no further changes to the current situation. Currently, the scope of European Community type-approval legislation does not include hydrogen powered vehicles. Thus, Member States may grant individual approvals without introducing legislation.

With no change in the policy regarding the approval of hydrogen vehicles, there is a high risk that the functioning of the internal market would be impaired. This would result in substantial cost implications for manufacturers and would entail possible repercussions on public safety.

There is a high risk that with no policy change, poor air quality and high levels of noise in cities of the European Union will remain an issue as atmospheric pollution and noise will continue to have a detrimental impact on human health.

This policy option would lead to uneven treatment of vehicle manufacturers with regard to the vehicle approval procedure and would lack any predictability for manufacturers to design their vehicles. Further, it would constitute a substantial barrier for the development of hydrogen technology in the EU.

Therefore, this policy option is not considered to be viable.

(2) Legislation at Member State level: This policy option would involve adoption of legislation at Member State level to accommodate the introduction of hydrogen vehicles.

With diverging standards emerging from Member States, the fragmented situation regarding the approval of vehicles would continue to exist, which would result in manufacturers facing unduly high development and approval costs and limited market accessibility. The policy option would not offer a solution for the present uncertainty regarding the approval of hydrogen vehicles, therefore would discourage further investment in the hydrogen technology.

In comparison with the ' Legislation at EU level' option, this policy option would result in substantially lower environmental benefits and would not ensure that hydrogen vehicles are at least as safe as conventional vehicles.

Thus, the option would result in a fragmented internal market and would not ensure that the policy objectives are attained. Therefore, this is not the approach to be followed.

(3) Legislation at European Union level: This policy option would involve the extension of the EC type-approval legislation to include hydrogen powered vehicles and setting out harmonised provisions for these vehicles.

Legislation at Community level prevents varying product standards emerging across Member States which results in fragmentation of the internal market and imposition of unnecessary barriers to intra-Community trade. Through harmonised standards on hydrogen powered vehicles it is possible to reap the economies of scale as production series can be made for the whole European market. This policy option would open up markets in some Member States where hydrogen vehicles could not currently be sold.

As shown in the impact assessment, this option will have the clear benefits of ensuring the proper functioning of the internal market, providing a high level of public safety throughout all EU Member States and improving noise and air quality levels sooner. This, in turn, will improve public health and, thus, will enable governments to generate savings.

Further, it would be ensured that the European Union keeps pace with other important automotive regions of the World with regard to the introduction of advanced technologies and the international competitiveness of the European industry might be improved.

Thus, this option is pursued in the proposal.

(4) Non-regulatory approach: Self-regulation through a negotiated commitment with the automotive industry to establish requirements for hydrogen powered vehicles.

It is not clear that a self commitment provides an adequate guarantee that hydrogen vehicles will be as safe as conventional vehicles or that there will be appropriate sanctions available if the self-commitment were to be breached. In addition, this approach is not likely to ensure that hydrogen vehicles are treated equally in comparison to conventional vehicles in the type-approval procedure. Moreover, it is not apparent that the use of a voluntary approach would offer any additional benefits to the industry, governments or the general public.

The option of non-regulatory approach was therefore not considered further.

The Commission services carried out an impact assessment listed in the Work Programme under the reference number 2006/ENTR/044.

3) LEGAL ELEMENTS OF THE PROPOSAL

Summary of the proposed action

The impact analysis has identified that the preferred policy option is the adoption of an EU Regulation with the purpose of incorporating hydrogen vehicles of categories M1, M2, M3 and N1, N2, N3 in the EU whole vehicle type approval framework.

The proposal foresees the amendment of the Framework Directive[3] in order to include hydrogen vehicles in the approval procedure. It specifies technical requirements to be applied for the type-approval of hydrogen components (hydrogen containers and hydrogen components other than containers) included in the hydrogen system in order to ensure that hydrogen related components are working in a proper and safe way. In addition, it includes requirements for the type-approval of vehicles with regard to the installation of hydrogen components or systems in vehicles. The proposal foresees the amendment of separate type-approval Directives and Regulations in order to include specific requirements for hydrogen powered vehicles.

Legal basis

The legal basis of the proposal is Article 95 of the Treaty.

Subsidiarity principle

The subsidiarity principle is respected, since the policy objectives cannot be sufficiently achieved by actions of the Member States and can be better achieved at Community level. European Union action is necessary because of the need to avoid the emergence of barriers to the single market.

Community action will better achieve the objectives of the proposal because it will avoid fragmentation of the internal market which would otherwise arise and will ensure the safety of hydrogen vehicles.

Proportionality principle

The proposal complies with the proportionality principle because it does not go beyond what is necessary in order to achieve the objectives of ensuring the proper functioning of the internal market while at the same time providing for a high level of public safety and environmental protection.

Choice of instruments

The proposed instrument is a Regulation. Other means would not be adequate for the following reason:

- The use of a Regulation is considered to be appropriate in providing the required assurance for compliance whilst not requiring the transposition into Member States legislation.

The proposal uses the "split-level approach" that has originally been introduced at the request of the European Parliament and used in other pieces of legislation, e.g. in the case of the Directive for heavy duty vehicle emissions[4] and the Regulation on the Euro 5 and 6 stage of light-duty vehicles emissions[5]. This approach foresees that the proposal and adoption of legislation will be made according to two different, but parallel, routes:

- first, the fundamental provisions will be laid down by the European Parliament and the Council in a Regulation based on Article 95 of the EC Treaty through the co-decision procedure (the 'co-decision proposal');

- secondly, the technical specifications implementing the fundamental provisions will be laid down in a Regulation adopted by the Commission with the assistance of a regulatory committee (the 'comitology proposal').

4) BUDGETARY IMPLICATION

The proposal has no implications for the Community budget.

5) ADDITIONAL INFORMATION

Simulation, pilot phase and transitory period

There are general transitory periods in the proposal in order to allow sufficient lead times for vehicle manufacturers.

Simplification

The proposal provides for simplification of administrative procedures for public authorities (EU or national). The proposal is included in the Commission's Work and Legislative Programme under the reference 2006/ENTR/044.

Repeal of existing legislation

The adoption of the proposal will not lead to the repeal of existing legislation.

Review/revision/sunset clause

The proposal foresees that technical requirements of the Regulation will be adapted to technical progress in the future.

European Economic Area

The proposed act concerns an EEA matter and should therefore extend to the European Economic Area.

Proposal for a

REGULATION OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL

on type-approval of hydrogen powered motor vehicles and amending Directive 2007/46/EC

(Text with EEA relevance)

THE EUROPEAN PARLIAMENT AND THE COUNCIL OF THE EUROPEAN UNION,

Having regard to the Treaty establishing the European Community, and in particular Article 95 thereof,

Having regard to the proposal from the Commission[6],

Having regard to the opinion of the European Economic and Social Committee[7],

Acting in accordance with the procedure laid down in Article 251 of the Treaty[8],

Whereas:

(1) The internal market comprises an area without internal frontiers in which the free movement of goods, persons, services and capital must be ensured. To that end a comprehensive Community type-approval system for motor vehicles is in place. The technical requirements for the type-approval of motor vehicles with regard to hydrogen propulsion should be harmonised to avoid the adoption of requirements that differ from one Member State to another and to ensure the proper functioning of the internal market while, at the same time, providing for a high level of environmental protection and public safety.

(2) This Regulation is a new separate Regulation in the context of the Community type-approval procedure under Directive [ .../.../EC ] of the European Parliament and of the Council of [DATE] establishing a framework for the approval of motor vehicles and their trailers, and of systems, components and separate technical units intended for such vehicles (Framework Directive)[9]. Therefore, Annexes IV, VI and XI to that Directive should be amended accordingly.

(3) Following the request of the European Parliament, a new regulatory approach has been introduced in EU vehicle legislation. This Regulation should therefore lay down only fundamental provisions on requirements for the type-approval of hydrogen systems and components, whereas the technical specifications should be laid down by implementing measures adopted following comitology procedures.

(4) In the transport sector, an increased share of more environmentally friendly vehicles should be aimed at and additional efforts should be undertaken in order to place more of those vehicles on the market. The introduction of vehicles with alternative fuels can produce a significant improvement in the urban air quality.

(5) Hydrogen is considered as a clean way of powering vehicles as vehicles propelled with hydrogen produce neither carbon based pollutants nor emissions of green-house gases from the tailpipe. However, care should be taken that the hydrogen fuel is produced in a sustainable manner, so that the overall environmental balance of introducing hydrogen as fuel for motor vehicles is positive.

(6) Defining the approval framework for vehicles using hydrogen would contribute to the confidence in the new technology for potential users and the public at large.

(7) Therefore, it is necessary to create an adequate framework in order to accelerate the placing on the market of vehicles with innovative propulsion technologies and vehicles which use alternative fuels with a low environmental impact.

(8) The majority of manufacturers are making important investments in the development of hydrogen technology and have already started to place such vehicles on the market. In future years, it is likely that the share of hydrogen powered vehicles will increase in the total fleet. Therefore, the specification of common requirements concerning the safety of those vehicles is necessary.

(9) It is necessary to implement safety measures for the hydrogen system and its components to obtain type-approval.

(10) It is necessary to take the installation of the hydrogen system and its components in the vehicle into account for the approval of the vehicle.

(11) Due to the characteristics of the fuel, hydrogen powered vehicles may require a specific treatment from rescue services. It is, therefore, necessary to lay down vehicle labelling requirements to inform those services of the fuel stored on-board of the vehicle.

(12) The manufactures should also take appropriate measures to prevent misfuelling of the vehicle.

(13) The measures necessary for the implementation of this Regulation should be adopted in accordance with Council Decision 1999/468/EC of 28 June 1999 laying down the procedures for the exercise of implementing powers conferred on the Commission[10].

(14) In particular, power should be conferred on the Commission to introduce requirements and test procedures relating to new forms of hydrogen storage or usage, additional hydrogen components and the propulsion system. Power should also be conferred on the Commission to establish specific procedures, tests and requirements with regard to the impact protection of hydrogen vehicles and integrated system safety requirements. Since those measures are of general scope and are designed to amend non-essential elements of this Regulation and to supplement this Regulation by the addition of new non-essential elements, they must be adopted in accordance with the regulatory procedure with scrutiny provided for in Article 5a of Decision 1999/468/EC.

(15) The objectives of this Regulation, namely the realisation of the internal market through the introduction of common technical requirements concerning motor vehicles using hydrogen, cannot be sufficiently achieved by the Member States. Due to the scale of the action required the objectives can be better achieved at Community level. Therefore, the Community may adopt measures, in accordance with the principle of subsidiarity, as set out in Article 5 of the Treaty. In accordance with the principle of proportionality, as set out in that Article, this Regulation does not go beyond what is necessary for that purpose,

HAVE ADOPTED THIS REGULATION:

Type 1 Seamless metallic container

Type 2 Hoop wrapped container with a seamless metallic liner

Type 3 Fully wrapped container with a seamless or welded metallic liner

Type 4 Fully wrapped container with a non-metallic liner.

2. The test procedures to be applied for the type-approval of those containers:

21. Burst test: The purpose of the test is to provide the value of the pressure at which the container bursts. In order to prove this, the container shall be pressurized to a given value, which should be higher than the nominal working pressure of the container. The burst pressure of the container shall exceed a specified pressure. The burst pressure of the container shall be recorded and shall be kept by the manufacturer throughout the service life of the container.

ANNEX VI Requirements for the installation of hydrogen components and systems

1. The hydrogen system shall be installed such that it is protected against damage.

It should be isolated from heat sources in the vehicle.

2. The hydrogen container may only be removed for replacement with a hydrogen container for the purpose of refuelling or for maintenance.

In the case of internal combustion engine, the container shall not be installed in the engine compartment of the vehicle.

It shall be adequately protected against any kind of corrosion.

3. Measures have to be taken to prevent hydrogen leakage during refilling and to make sure that the removal of a removable hydrogen storage system is done safely.

4. The refuelling connection shall be secured against maladjustment and shall be protected from dirt and water.

5. The hydrogen container shall be mounted and fixed so that the specified accelerations can be absorbed without damage of the safety related parts when the hydrogen containers are full.

6. The hydrogen fuel supply lines shall be secured with an automatic valve. The refuelling line shall be secured with a valve. The valves shall close if a malfunction of the hydrogen system requires so or any other event that results in the leakage of hydrogen occurs. When the propulsion system is switched off, the fuel supply from the container to the propulsion system shall be switched off and remain closed until the system is required to operate.

7. No hydrogen component, including any protective materials that form part of such components, shall project beyond the outline of the vehicle or protective structure. This shall not apply if a hydrogen component is adequately protected and no part of the hydrogen component is located outside this protective structure.

8. The hydrogen system shall be installed such that it is protected against damage so far as is reasonably practical, such as damage due to moving vehicle components, impacts, grit or due to the loading or unloading of the vehicle or the shifting of loads.

9. No hydrogen component shall be located near the exhaust of an internal combustion engine or other heat source, unless such components are adequately shielded against heat.

10. The ventilating or heating system for the passenger compartment and places where leakage or accumulation of hydrogen is possible shall be designed so that hydrogen is not drawn into the vehicle.

11. In the event of accidents, it shall be ensured so far as is reasonably practicable that the pressure relief device and the associated venting system remain capable of functioning. The venting system of the pressure relief device shall be adequately protected against dirt and water.

12. The passenger compartment of the vehicle shall be separated from the hydrogen system in order to avoid accumulation of hydrogen. It shall be ensured that any fuel leaking from the container or its accessories does not escape to the passenger compartment of the vehicle.

13. Hydrogen components that could leak hydrogen within the passenger or luggage compartment or other non-ventilated compartment shall be enclosed by a gas tight housing or by an equivalent solution as specified in the implementing legislation.

14. Electrically operated devices containing hydrogen shall be insulated in such a manner that no current passes through hydrogen containing parts, in order to prevent electric sparks in the case of a fracture.
