7 EXECUTIVE SUMMARY Background The Regulations, Codes and Standards (RCS) gap analysis was undertaken in the frame of the HyLIFT-DEMO project as part of the activities described in Work package 3 entitled "Safety Certification and RCS" (WP3) of the Description of Work (DoW), where it is required to identify future RCS needs in order to enable commercial high volume certification & use of hydrogen powered fuel cell material handling vehicles. This report This report assesses the data and evidence resulting from a survey performed with the aim to identify and analysis of RCS gaps on fuel cell (FC) powered forklifts and duplications within the standards industry as they relate to the deployment of and Fuel Cell power system for the lift truck market. Findings Existing RCS gaps as regards fuel cell powered forklifts are currently addressed by the standardization process in place at Working Group 6 "Fuel cell system for propulsion and auxiliary power units (APU)" of the Technical Committee 105 "Fuel Cell Technologies" of the International Electrotechnical Commission (IEC TC 105 WG6) for both performance and safety. Eventually, the standards will have performance requirements and type test methods available for system components and the entire FC power system. It is expected that compliance of FC forklifts with these standards presumes to meet the essential legal requirements of the applicable EU directives (i.e. Machinery /42/EC, Low Voltage /95/EC, Pressure Equipment 3-97/23/EC, ATEX Equipment 4-94/9/EC) and to facilitate the product certification process. Permitting guidelines 5 for the installation of hydrogen refuelling stations are also available including for indoor use. 6,7 1 See at 2 See at 3 See at 4 See at 5 D K Pritchard, M Royle & D Willough, Installation permitting guidance for hydrogen and fuel cell stationary applications: UK version, HSE Research Report RR715, 2009, Health and Safety Laboratory, Harpur Hill Buxton, Derbyshire, SK17 9JN, accessible at 6 WP2 HyApproval - Handbook for Refuelling Station Approval, June 2008, accessible at v

8 Conclusions Overall conclusions are as follows: FC forklift performance test methods (IEC document 105/xxx/CD) and safety requirements and assessment methods (IEC document 105/407/CD) are currently under preparation at IEC TC 105 WG6, Existing permitting guidelines for the installation of hydrogen refuelling station should be used, and Operation and maintenance procedures should be defined by OEM (FC power system / forklift manufacturer). Suggestions and recommendations On the basis of the gap analysis, the following suggestions and recommendations emerge: To provide input on drafting of IEC & IEC Committee Drafts to IEC TC 105 WG6 and To demonstrate viability of these two Committee Drafts by validation trough testing. 7 NASA Safety Standard for and Systems: Guidelines for System Design, Materials Selection, Operations, Storage and Transportation, NSS , Office of Safety and Mission Assurance Washington, DC 20546, February 1997, accessible at cancelled in July 2005; Future acquisitions should cite AIAA Guide to Safety of and Systems, accessible at vi

9 1 INTRODUCTION AND MOTIVATION This chapter provides background information on the project and explains the set-up of this report. Background The Regulations, Codes and Standards (RCS) gap analysis was undertaken in the frame of the HyLIFT-DEMO project 8 as part of the activities described in Work package 3 (WP3) of the Description of Work (DoW), where it is required to identify future RCS needs in order to enable commercial high volume certification & use of hydrogen powered fuel cell material handling vehicles. This report This report assesses the data and evidence resulting from a literature survey performed with the aim to identify and analyse RCS gaps on fuel cell (FC) powered forklifts and duplications within the standards industry as they relate to the deployment of and FC power system for the lift truck market. RCS gap analysis evaluations for H 2 technologies have been performed in the past years, starting with the HarmonHy project, 9 an European Union funded Specific Support Action (SSA) under the Sixth Framework Programme of the European Community for research, technological development and demonstration activities contributing to the creation of the European Research Area and to innovation, 2002 to 2006 (FP6) aiming to make an assessment of the activities on hydrogen and fuel cell RCS on a worldwide level. This report focuses on gaps in RCS that enables the production, commercialization and use of lift truck based on fuel cell technology. 8 See the project website at 9 Harmonization of Regulations, Codes and Standards for a sustainable and Fuel Cell Technology, accessible at 7

10 2 METHODOLOGY This chapter explains the pilot assessment methodology piloted in the project for the gap analysis. The gap analysis process was designed as a review of RCS already available or under preparation that are specifically related to the forklift application. There are many processes related to H 2 technology, an overview of all processes is given in Table Only the processes with assess tag have been investigated in this document.

13 Table 2: RCS citations for hydrogen related to forklifts RCS Scope Reference Organization Comment Standard for Fuel cell Power System For Installation in Industrial Electric Trucks The requirements cover fuel cell power systems currently noted as intended to be installed in type E, industrial trucks used in locations as defined in the Fire Safety Standard for Powered Industrial Trucks including Type Designations, Areas of Use, Conversions, Maintenance and Operations NFPA 505, and the National Electrical Code NFPA 70. The scope only covers those systems that incorporate a permanently mounted pressure vessel containing compressed hydrogen gas for designs that are fuel cell without the pressure vessel being removed from the industrial truck (on board fuelling). At this time, the standard is limited to systems with maximum pressures of 25 or 35 MPa. UL 2267 UL Even though the work of the High Pressure Task Group has been completed, there is a current proposal bulletin out for balloting that addresses tank replacement markings, changes to vibration and other testing and additional proposals for the pressure vessel section. Follow up revisions to the standard such as replacing the "Type E" industrial truck designation with the new industrial truck "Type CGH" (compressed gaseous hydrogen) designation in accordance with NFPA 505 are planned, to address developments in the industry and the codes that affect it.
