ABSTRACT
Large quantities of hydrogen have been used safely as a chemical feedstock and industrial gas for many years, and standards, codes, and regulations governing its storage, distribution, and use at industrial sites are well established. Hydrogen is used as a feedstock in the petroleum refi ning, chemical, petrochemical, and synthetic fuels industries. Examples include making ammonia for fertilizer and removing sulfur in petroleum refi ning for products such as “reformulated” gasoline. Hydrogen is also used in the food processing, semiconductor, glass, and steel industries as well as by electricity utilities to cool the rotor and stator coils in large turbine generators. The use of hydrogen as an energy carrier for consumer markets is expected to grow over the next decade, and the development and promulgation of codes and standards for this use are essential to establish a marketreceptive environment for commercial hydrogen products and systems.
