  1. Safety Assessment Requirements for the Approval of a Hydrogen Refueling Station Menso Molag Ingrid Heidebrink Menso.Molag@TNO.NL

  2. HyApproval project Stakeholders for HRS Approval Interviews of Stakeholders Safety requirements of the approving authorities Conclusions and recommendations Contents Safety Assessment requirements for HRS Approval

  3. Demonstration projects: difficult to get approval for a HRS Need for Harmonisation of a HRS and HRS approval HyApproval: Facilitate the HRS approval WP3 Stakeholders? What safety information is needed? How is it assessed by the authorities? How can it be harmonised? Background of the HRS approval Safety Assessment requirements for HRS Approval

  4. Industry Authorities Advisors to the authorities Labour or industry or environmental inspectorate Fire Brigade Public Consumers People living or working in the environment of a HRS Stakeholders in the Approval Process Safety Assessment requirements for HRS Approval

  5. Responsibility and liability of stakeholders Required information Occupational and external safety policy concerning HRS Assessment criteria HRS Applied guidelines and methods to assess consequences and risks Off-site safety and land use planning Inspection Emergency planning Dissemination of HyApproval Handbook Remarks / gaps Interviews in: France, Germany, Italy, Netherlands, Spain, USA, Interview questionaire Safety Assessment requirements for HRS Approval

  6. Need for H2 specific laws/regulations Required permits Building permit Environmental permit Operating permit Safety policy Prevention of accidents Create a safety zone or safety distance Optimal preparation of emergency services Safety assessment Requirements of the approving authoritiesCommon elements Safety Assessment requirements for HRS Approval

  7. Definition of HRS Safety distances • Explosion Hazard zones • ATEX [94/9/EC, IEC/EN60079-10, NFPA 70] • 1st , (2nd ) party risks • Safety distances or minimum separation distances Low probabilty accidents with consequences • Frequency > 3.5 * 10-5 per year • Consequences inside HRS • 1st, 2nd party risks [EIGA DOC 75/07/E] • External safety distances: Very low probability, high consequence accident scenarios • Frequency ≤ 3.5 * 10-5 per year • Consequences outside boundary of HRS • 1st, 2nd, 3rd party risks Safety Assessment requirements for HRS Approval

  8. Prescriptive: built according applicable guidelines All interviewed countries Deterministic: no 2nd and 3rd party consequences Germany, Spain Probabilistic: demonstrate acceptable 2nd and 3rd party risks Netherlands Safety Assessment Requirements Safety Assessment requirements for HRS Approval

  9. Conclusions and recommendations • Industry focuss : Built and operate a safe HRS • Authority focuss : Safe environment of HRS • Early and good communication between stakeholders • Draft specific guidelines for design, lay-out and inspection HRS • HyApproval Handbook is a good start to facilitate HRS approval • Handbook must be updated • New technology • Reduction of uncertanties in safety assessment • Harmonisation approval process Safety Assessment requirements for HRS Approval
