Risk management of the PV - hydrogen storage - fuel cell system is a significant assessment within the project. As part of the overall design process we will include a risk management assessment of the system elements. This is to ensure that risk levels of hazards are managed so they can be either regarded as tolerable or negligible risks.

The Hindenburg Disaster. Hydrogen
can be highly explosive.

The risk management approach adopted is as follows;

1. Hazard identification.
2. Risk assessment
3. Risk reduction.

A 'hazard' is defined as 'something that can lead to an undesirable outcome in the process of meeting an objective'. A 'risk' is generally defined as 'a measure of a hazard's significance involving simultaneous examination of its consequences and probability of occurrence for the scenario.' The risk level has been assessed using the quantitative approach of a risk matrix system and the classifications for the consequences were as follows;

1. catastrophe
2. hazardous effect
3. major effect
4. minor effect

The classifications used for the probability of occurrence are as follows;

1. very likely
2. reasonably probable
3. very unlikely
4. reasonably remote
5. extremely remote.
