Summary
Functional unit: 
Hydrogen plant size : 1.5 million Nm3 / day (57 million scfd)
Goal and scope of the summary: 
Hydrogen is used in a number of industrial applications with today's largest consumers being ammonia producing facilities, oil refineries and methanol production plants. Hydrogen is generally produced by the consumer and the most common method is steam reforming of natural gas.

Although hydrogen is considered to be a clean fuel, it is important to recognize that its production may result in environmental consequences. The energy balance of the system shows that for every 0.66 MJ of hydrogen produced, 1 MJ of fossile energy must be consumed. From both an environmental and economic standpoint, it is important to increase the energy efficiencies and ratios of any process. Future work will involve comparing this study with hydrogen production via other routes such as biomass, wind and photovoltaics.
