1 Safety aspects and stakeholders responsibilities EVS24 H2 Session2: Roles and responsibilities towards sustainable transportation Gerd Petra Haugom, DNV/International Association for Hydrogen Safety (HySafe) Angunn Engebø, DNV, Cleaner Energy 13 May 2009

2 Why DNV and Hydrogen Safety? In line with DNVs purpose, vision and values - Safeguarding life, property and the environment - Global impact for a safe and sustainable future Challenges: - New technological solutions - Further pre-normative work required - input to harmonised regulations, codes and standards for hydrogen - Limited availability of H 2 specific experience, data and information - Prediction tools need further development and validation Just what the environment needs from a car. Water Kilde: DaimlerChrysler Slide 2

3 DNV Hydrogen Services & Solutions We develop, implement, maintain and continually improve best practices in SHE management We safeguard integrity and maintain optimal production safely and cost-efficiently SHE Risk Management Asset Risk Management We provide you with the confidence that technology will function reliably We ensure your projects are properly managed through transparent risk based verification and certification Technology Qualification Verification Slide 3

4 NoE HySafe - Integration of the EU H2 Safety Research Consortium 24 partners from 12 European countries + Kurchatov Institute/Russia + University of Calgary/Canada 13 research institutes, 7 industry partners, 5 universities ~150 scientists actively involved GOAL: Contributing to the Safe Introduction of Hydrogen Technologies and Applications Budget Total > 13 M ; EC grant < 7 M Time frame: 5 years 03/ / Mai 2009 Det Norske Veritas AS.

5 HySafe NoE achievements Developing, harmonising and validating methodologies for safety assessments and undertaking safety studies - Risk Management and risk assessment methodologies - Acceptance criteria - Risk based determination of safety distances and zone classification - Developing reference QRA models (HyQRA) Dispersion, combustion and explosion modelling, benchmarking and validation of CFD tools Specialised research facilities Mitigation, material compatibility and structural integrity Input to and monitoring of regulatory activities Recommendations for the safety aspects of the use of high pressure H2 in fuel cell cars - Based on investigation of the effect of HPH2 induced cracking Slide 5

6 Achievements HySafe NoE Investigations on the use of hydrogen in enclosed spaces - Tunnels - Garages Development of a Hydrogen Incident and Accident Database (HIAD) Biennial Report Hydrogen Safety Dissemination website - Hydrogen Safety Information System (HySafe IS) Organizing training and educational programmes on hydrogen safety Slide 6

7 International Association for Hydrogen Safety the European focal point for hydrogen safety issues. Objectives Facilitate maintenance and further development of infrastructure for hydrogen safety research Provide support to EC, JTI and RCS bodies in hydrogen safety issues Provide/facilitate consolidated educational and training frameworks (academic & technical) Disseminate knowledge via communication/information platforms to stakeholders Initiate and promote coordinated hydrogen safety research Slide 7

8 Development needs (1) Further refine and develop risk assessment methodologies Further development of database for hydrogen incidents and accidents to facilitate learning from experiences (HIAD) Tunnel safety - Release, mixing and distribution phenomena; e.g. stratification - Fire and explosion effects Apply current knowledge to develop criteria for safe parking of hydrogen vehicles in confined spaces, -e.g. parking garages - Important with suitable ventilation criteria for garages - Permeation and ventilation criteria Slide 8

9 Development needs (2) Dissemination example: New version of ASHRAE building code (USA) (american standard for buildings) has removed general minimum criteria for ventilation in private parking garages For hydrogen vehicles parked in garages there will always be some permeation of hydrogen Maximum safely allowable permeation depends on ventilation where the car can be allowed parked for a long time Without a criteria for minimum ventilation, it therefore becomes very difficult to facilitate safe parking of hydrogen vehicles in such garages. If the body developing this standards had knowledge of hydrogen - and other gases as natural gas, this could been avoided! Slide 9

10 Development needs (3) Harmonisation of Approval procedures, - example: Hydrogen Refuelling Stations: - HyApproval Handbook for approval of Hydrogen Refuelling Stations in Europe is a good basis Hydrogen vehicles: - Regulation for type approval of hydrogen powered motor vehicles in Europe published Further work for harmonisation of approval procedures for hydrogen systems will contribute to the smooth introduction of hydrogen avoiding spending too much resources on varying local/regional approval regimes. General: - In general, risk assessments are recommended as a useful tool to secure an acceptable safety level for new technologies and solutions Slide 10

11 Recommendations National as well as international support and cooperation is important. Including private-public cooperation and partnerships - to facilitate the safe introduction of hydrogen as an energy carrier and contributing to closing knowledge gaps, and facilitate harmonisation of approval requirements Support dissemination and knowledge sharing, e.g.: - International Association for Hydrogen Safety - International harmonisation of requirements for the use of hydrogen systems at a level of detail adequate for current technology - IEA activities on hydrogen safety - International Partnership for the Hydrogen Economy (IPHE) - Continuation of education and training activities on Hydrogen Safety - Continuation of HIAD database for continued learning and knowledge development of hydrogen incidents and accidents Slide 11

12 Summary Governments and authorities should support the SAFE introduction of hydrogen as an energy carrier in the transport sector. This includes support to: - Close knowledge gaps on hydrogen safety - Facilitate European and International Cooperation, dissemination and knowledge sharing HySafe recommends funding of further pre-normative work to formulate requirements for use of hydrogen in confined spaces. Responsibility jointly on research, industry and regulatory bodies, but authorities must contribute with funding. Slide 12
