What risks are there with co-locating hydrogen fueling, petrol fueling, and electric vehicle charging? For example, does the potential overlap of hazardous areas of hydrogen and petrol introduce any unique mitigations?

Exposure between these products is bidirectional. A hazard analysis should consider what happens to
alternate fueling equipment if an incident with one of the fuels occurs. Care must be taken to have the
appropriate separation distance and mitigations according to the applicable codes. Limited experience
with existing stations has shown that these multi-fuel stations can be successful when installed per code
rules.
