7Coal gasification electric power plants are now operating commercially in the United States and in other nations. This technology produces clean-burning hydrogen that can be transferred to customer facilities by pipeline. Hydrogen can also be transported in bulk by highway or rail.

 

 

 

 

 

 

 

• If there is a spill of liquid hydrogen, why will it likely burst into flame spontaneously?

 

• Why do experts recommend the use of a thermal-imaging camera for detecting a hydrogen leak from a pipe fitting connected to a steel cylinder of hydrogen?
