Safety
From Roads2HyCom Hydrogen and Fuel Cell Wiki - A Reliable Source of Information - Edited by Technology Experts Only
Safety metrics gives the information about how safe the process or system is. Energy convertors, local/on-borad storage, retail and depot, transport of the fuel and production of fuel are studied for safety ob the basis of following sub-metrics.
- Likelihood of technology breakdown (including misuse)
- Severity of failure
The Safety and Security Assessment is a vital part of the Roads2HyCom project. It also comprises the analysis of Hydrogen Regulations.
| OVERALL ASSESMENT OF TECHNOLOGY | ||
| Generic Sub Metric | Data or Rating | Units |
| Likelihood of safety-critical failure (Death, Injury, Damage): Relative to existing technology | Data | no./year |
| Severity of failure: Scale of seriousness | Rating | 0-4 |
| Task | Sub-metric | Data or Rating | Unit |
| FUEL (H2) PRODUCTION | No. of incidents: (shut-downs, fuel leakage, tech failure) | Data | no. / year |
| No. of accidents causing injury to people, damage to property/environment | Data | no. / year | |
| RETAIL & DEPOT | Leaks at retail/depot per number of tanks: Likelihood of a detonating gas concentration | Data | no./year |
| Severity of failure: Risk for workers and residents | Rating | 0-4 | |
| TRANSPORT | No. of transport interruptions | Data | no./year |
| Severity of failure: Danger for residents along the transportation routes | Rating | 0-4 | |
| LOCAL/ ON-BOARD STORAGE | Likelihood of technology breakdown (inc. misuse): Theoretically, how often a total break down happens | Data | no./year |
| Severity of failure: From not verry important, easily repaired, to dangerous for user and system | Rating | 0-4 | |
| ENERGY CONVERTER | Technology breakdown (including misuse): Number of failures that cause a system stop | Data | no./year |
| Severity of failure: From not verry important, easily repaired, to dangerous for user and system | Rating | 0-4 |
