The hydrogen station at Messedamm in Berlin
Worldwide the largest H2 filling station with a capacity of more than 100 cars per day with CGH2 and LH2
First fully integrated H2 filling station in Europe
In operation since November 2004
Open 24hrs daily for hydrogen refuelling

Hydro – infrastructure partner delivering CGH2
Ref. no: 100020 • Date: 2005-09-09 • Page: 10 • Hydro Oil & Energy
The challenge How to incorporate a Hydrogen station into an ordinary petrol station
- Central location in Berlin with public and in highly populated area- Limited space available
Acceptable risk level- Hydrogen productions at site- Storage of both CGH2 and LH2
Approval from authorities
Ref. no: 100020 • Date: 2005-09-09 • Page: 11 • Hydro Oil & Energy
The response to the challengesSafety is CEP number one priority
Infrastructure partner agreement
- Use EIHP recommendations when planning and designing the station
- Use risk based safety management
- Perform HAZID- Perform HazOp studies- Perform QRAs- Follow BP HSE requirements
during construction and operation
Ref. no: 100020 • Date: 2005-09-09 • Page: 12 • Hydro Oil & Energy
Approvals: Roles and responsibilities
BP/Aral responsible for contact with authorities and TÜV for overall approvals
The individual partners responsible for their own properties to give sufficient information / documentation for the approval process
Hydro and Linde responsible for CE marking of all equipment
Ref. no: 100020 • Date: 2005-09-09 • Page: 13 • Hydro Oil & Energy
Background- Prepare approval of production unit- To address concerns raised in the MMI HAZID report for CEP Berlin- Use of the CFD software FLACS
Product- Explosion risk analysis, general- Explosion pressure contours for different risk levels- Missile evaluation

Risk and acceptance criteria
Consequence
Frequency
Risk is a combination of accidental event consequence and frequency
Unacceptable riskAcceptable riskNegligible risk
Acceptance criterion

Explosion risk analysis conclusions and results
Explosions with frequencies of 10-6, 10-5 and 10-4 y-1 will all detach wall panels from container steel frame
Explosions with a frequency of 10-3 y-1 or more often will not damage the container
Explosion pressures from the 10-6, 10-5 and 10-4 y-1 events will not harm humans, but may break glass up to 15 m away
Assumed that falling wall panels will cause damage to bystander, which lead to risk contours
Missiles were assessed to consist a minor hazard due to short explosion duration (small impulse) if walls were secured
Modifications of container design:- Split wall panel to reduce safety distance- Isolation valve to prevent backflow from
buffer tank to electrolyser container

Approvals
The hydrogen station is built and operated in accordance with BetrSichV
- CE marked
- Directives 1999/92/EC: Explosion Protection Document (EPD) from TÜV based on EPDs from Hydro and Linde
First permission from LAGetSi, to operate the hydrogen filling station, August 28th 2003
Updated permission from LAGetSi based upon the one from 2003, August 13th 2004
Final inspections certificates of TÜV and LAGetSi done after station was built
Ref. no: 100020 • Date: 2005-09-09 • Page: 18 • Hydro Oil & Energy
Lessons learned
Establish clear and common objectives
- Both for the design-phase and the operating phase
Ensure safety work is part of the project plan and safeguard a common approach to safety activities
Agree upon risk acceptance criteria
Involve authorities at an early stage
