Quizplus · Accepted Answer

The primary commercial use of hydrogen in the United States is for the Haber process to manufacture ammonia, which is an important fertilizer and industrial chemical. While hydrogen has potential as an automobile fuel, it is not currently used on a large scale for this purpose. Hydrogenation of vegetable oils and manufacture of methanol are also important industrial uses of hydrogen, but they are not the primary commercial use in the United States. Hydrogen is used as a rocket fuel, but this is a relatively small market compared to the manufacture of ammonia.
