Hydrogen is a medium for storing energy, otherwise known as an energy carrier. All energy carriers and fuels, such as gasoline and natural gas, have the characteristic of being volatile (containing potential energy). Hydrogen’s benefits and disadvantages differ from the fossil fuels commonplace in an advanced energy utilizing society such as in the United States.

The Hydrogen Industry often uses hydrogen sensors to help detect hydrogen leaks and has maintained a high safety record using them for decades. By comparison, natural gas is also odorless, colorless, and tasteless, but industry adds a sulfur-containing odorant to make it readily detectable by people.
The United States currently produces and safely uses more than nine million metric tons of hydrogen each year, but primarily in a controlled industrial environment. Codes and standards applicable to hydrogen technologies, as well as information on the unique characteristics of hydrogen and its handling, will be essential to achieving the vision of a hydrogen [...]
