.. Hydrogen has the widest
explosive/ignition mix range with air of all the gases except acetylene. That means that whatever the mix proportion between air and hydrogen, a hydrogen leak will lead to an explosion, not a mere flame.

Laws and RegulationsLaws and Regulations
Flame detectors must be used -Implementation of higher standards to detect
early leaks -“Standard for the installation of stationary fuel
cell power systems” (Wiki) - Codes and standards have been a major barrier to
deploying hydrogen technologies and developing a hydrogen economy
-DOE is currently in the process of devising safety codes, standards and regulations

SustainabilitySustainability
Hydrogen can be produced in a variety of ways -Most efficient way is by electrolysis of water -Water can be recycled and used for drinking -Overall sustainable as it is the most abundant
element in the universe
